BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The embodiment of the invention relates to a tool holder, and in particular to a
tool holder which allows hexagon wrenches to be received therein and taken out easily.
2. Description of Prior Art
[0002] Currently, hexagon wrenches have been widely used in our daily life. In practice,
a plurality of hexagon wrenches having different outer diameters are received in a
hexagon wrench box, so that a user can carry these hexagon wrenches easily. For this
reason, the hexagon wrench box is a practical and popular utensil for most people.
[0003] A common tool holder is provided with a plurality of receiving holes having different
inner diameters corresponding to the outer diameters of the hexagon wrenches respectively,
so that all the hexagon wrenches can be inserted into these receiving holes correctly.
In general, the hexagon wrench having a smaller outer diameter is first inserted into
a corresponding receiving hole. Then, the hexagon wrench having a larger outer diameter
is inserted into another corresponding receiving hole. Further, bending portions of
all L-shaped hexagon wrenches are disposed horizontally on the tool holder for easy
use or stage. However, the fact that bending portions of all the L-shaped hexagon
wrenches are horizontally disposed in the tool holder will make it inconvenient for
the user to take the hexagon wrenches out of the tool holder. For example, if a user
needs to take a small-diameter hexagon wrench out of the tool holder, he/she has to
first rotate the bending portion of other large-diameter hexagon wrenches until they
do not interfere with the bending portion of the desired small-diameter hexagon wrench.
After using the small-diameter hexagon wrench and inserting it back into the tool
holder, the user has to rotate the bending portions of other large-diameter hexagon
wrenches back to their original position, which is inconvenient for the user. Further,
when the user intends to use a much smaller hexagon wrench, he/she needs to rotate
more hexagon wrenches each larger than the desired small-diameter hexagon wrench.
Thus, in the conventional tool holder, it is very inconvenient to take out the hexagon
wrenches and put them back.
[0004] In view of the above, the present inventor proposes a novel tool holder based on
his expert experience and delicate researches to solve the problems in conventional
tool holder that the hexagon wrenches cannot be taken out and put in conveniently.
SUMMARY OF THE INVENTION
[0005] A primary objective of the embodiment of the invention is to provide a tool holder,
which allows each hexagon wrench to be stored in position correctly without falling
off easily. When the user intends to take out a desired hexagon wrench, it is unnecessary
for the user the rotate other hexagon wrenches adjacent to the desired hexagon wrench.
The user only needs to rotate the desired hexagon wrench and forwardly draw it out,
which is convenient in use.
[0006] In order to achieve the above objective, the embodiment of the invention provides
a tool holder, which includes a receiving unit having a first receiving seat and a
second receiving seat. The tool holder is configured to allow hexagon wrenches (Allen
wrenches) to be received therein from two sides. The first receiving seat and the
second receiving seat are connected to each other via pivotal shafts and associated
pivotal holes, so that these two receiving seats can be pivotally folded or unfolded.
Each receiving seat is provided with a plurality of closed oval receiving holes having
different dimensions and arranged in a row, so that the hexagon wrenches can be inserted
in the receiving holes respectively. An axial end of each receiving hole is provided
with a tapered inclined surface. Each receiving hole is provided with two symmetrical
buckling portions. Each buckling portion is provided with a first rib and a second
rib. Since the hexagon wrench is formed into an L-shaped wrench having six engaging
surfaces. The user rotates the hexagon wrench in such a manner that the six engaging
surfaces cooperate with the two buckling portions to thereby fix or release the hexagon
wrench. Since both ends of each receiving hole are provided with two inclined surfaces,
the user rotates the hexagonal wrench by 60 degrees and forwardly draws the hexagonal
wrench with the engaging surfaces of the hexagonal wrench leaving the buckling portions
and passing through the second rib. In this way, the hexagonal wrench can be taken
out of the receiving seat.

DETAILED DESCRIPTION OF THE INVENTION
[0008] Please refer to FIGS, 1 to 9. A preferred embodiment of the invention provides a
tool holder, which includes a receiving unit 10.
[0009] First, with reference to FIGS. 1 to 3, the receiving unit 10 comprises a first receiving
seat 11, a second receiving unit 12, and a plurality of receiving holes 13 provided
on the two receiving seats 11 and 12. The first receiving seat 11 is provided with
pivotal posts 111 pivotally connected to pivotal holes 121 of the second receiving
seat 12 respectively. By this arrangement, the first receiving seat 111 and the second
receiving seat 12 can be pivotally folded or unfolded by using the pivotal connection
between the pivotal posts 111 and the pivotal holes 121. The receiving seats 11 and
12 are provided with the receiving holes 13 having closed oval shapes and arranged
in a row. An upper portion and a lower portion of each receiving hole 13 are symmetrical
to each other. An axial end of each receiving hole 13 is provided with a tapered inclined
surface 132. Each receiving hole 13 is provided with two buckling portions 131 symmetrically
to each other. Each buckling portion 131 is provided with a first rib 1311 and a second
rib 1312 for allowing a hexagon wrench 20 to be inserted in the receiving hole 13
properly. Two opposite sides of the hexagon wrench 20 cooperate with the two buckling
portions 131 to thereby fix or release the hexagon wrench 20. After the user slightly
rotates the hexagon wrench 20 to leave the buckling portions 131, the user can rotate
the hexagon wrench 60 by 60 degrees and then pushes the hexagon wrench 20 toward the
inclined surface 132 to thereby leave the bucking portions 131. In this way, the user
can take out the hexagon wrench 20 along the axial direction of the inclined surface
132.
[0010] Please refer to FIGS. 1 to 3 again. The hexagon wrench 20 is formed into an L shape
and has six engaging surfaces 21. The engaging surfaces 21 are configured to abut
against the buckling portions 131 of the receiving hole 13, so that the hexagon wrench
20 can be properly positioned in the receiving unit 10.
[0011] Please refer to FIGS. 3 to 9, which are schematic views showing the actions of the
embodiment of the invention respectively. When the hexagon wrench 20 is inserted into
the receiving hole 13, the engaging surfaces 21 will be wedged and thus positioned
between the first rib 1311 and the second rib 1312 of the buckling portion 131. The
distance between the first rib 1311 and the second rib 1312 is greater than the width
of the engaging surface. In the state shown in FIGS. 3 and 6 that the hexagon wrench
20 does not leave the buckling portions 131, after the user slightly rotates the hexagon
wrench 20 with its engaging surfaces 21 leaving the buckling portions 131 to cross
the first rib 1311 and the second rib 1312, the hexagon wrench 20 gets loosened as
shown in FIG. 4. Next, the user continues to rotate the hexagon wrench 20 until a
60-degree angle is formed between the hexagon wrench 20 and the receiving seat as
shown in FIGS. 5 and 7. At this time, by using the inclined surface 132 provided in
the receiving hole 13, the user can pull forwardly the hexagon wrench 20 inserted
into the receiving hole 13 to pass through the second rib 1312 until the hexagon wrench
20 abuts against the inclined surface 132 as shown in FIG. 8. Then, the user can exert
a force to draw the hexagon wrench 20 out of the buckling portions 131. At this time,
as shown in FIG. 9, the user can take the hexagon wrench 20 out of the receiving unit
10 easily.
[0012] Although the receiving unit 10 of the embodiment of the invention is constituted
of a first receiving seat 11 and a second receiving seat 12, the receiving unit 10
may be integrally formed into one body. Further, the receiving unit 10 may be made
of soft materials, so that the engaging surfaces 21 of the hexagon wrench 20 can be
wedged into or removed from the buckling portions 131 of the receiving hole 13 easily.
However, in other embodiments (not shown), the first receiving seat 11 and the second
receiving seat 12 can be used as two separate parts without departing from the scope
of the embodiment of the invention.
[0013] Although the invention has been described with reference to the foregoing preferred
embodiments, it will be understood that the invention is not limited to the details
thereof. Various equivalent variations and modifications can still occur to those
skilled in this art in view of the teachings of the embodiment of the invention. Thus,
