the wrench 30 is rotated relative to the main body 40 of the tool display rack to
test the rotation angle of the drive stud 310 of the wrench 30. However, the square
hole 43 of the main body 40 is larger than the drive stud 310 of the wrench 30, so
that the rotation angle of the drive stud 310 of the wrench 30 is not tested exactly.
[0004] Another conventional tool display rack in accordance with the prior art shown in
Figs. 10-12 comprises a main body 40 formed with a circular hole 41, and a locking
member 50 extended through the drive head 31A of a wrench 30A and having a first end

extended through the circular hole 41 and locked on a bottom of the main body 40 to
secure the drive head 31A of the wrench 30A on the main body 40. In such a manner,
the hexagonal positioning portion 52 of the locking member 50 is secured in the drive
head 31A of the wrench 30A, and the wrench 30A is rotated relative to the main body
40 of the tool display rack to test the rotation angle of the ratchet wheel 32A of
the drive head 31A of the wrench 30A. However, the tool display rack needs to provide
a locking member 50, so that the tool display rack has a complicated construction,
thereby increasing costs of fabrication. In addition, the locking hook 51 of the locking
member 50 cannot hold the main body 40 closely, so that the locking member 50 is easily
rotated with the drive head 31A of the wrench 30A, thereby decreasing the testing
precision.

DETAILED DESCRIPTION OF THE INVENTION
[0012] Referring to the drawings and initially to Figs. 1-4, a tool display rack 20 in accordance
with a first embodiment of the present invention is used for mounting a tool 10. The
tool 10 has a drive head 11 and a neck portion 12. The drive head 11 of the tool 10
has a square drive stud 110.
[0013] The tool display rack comprises a main body 21, a mounting portion 211 mounted on
the main body 21 to allow passage of the drive stud 110 of the tool 10 and having
an inner edge closely urged on a peripheral wall of the drive stud 110 of the tool
10 to produce a contact friction therebetween, and a pressing member 22 pivotally
mounted on the main body 21 and urged on the neck portion 12 of the tool 10.
[0014] The main body 21 has a first end formed with a hanging portion 210 for hanging the
main body 21. The mounting portion 211 is mounted on a mediate portion of the main
body 21 and is preferably a through hole having a diameter slightly smaller than a
size of the drive stud 110 of the tool 10. Preferably, the main body 21 is integrally
formed with the mounting portion 211.
[0015] The mounting portion 211 has a peripheral wall provided with a plurality of elastic
portions 212 each radially extended outward therefrom. Preferably, each of the elastic
portions 212 of the mounting portion 211 is an elongated slit. The peripheral wall
of the mounting portion 211 is provided with a plurality of elastically deformable
holding portions 213 located between the elastic portions 212. Preferably, the mounting
portion 211 is integrally formed with the elastic portions 212 and the holding portions
213.
[0016] As shown in Fig. 3, the drive stud 110 of the tool 10 is inserted into the mounting
portion 211 of the tool display rack 20. At this time, the mounting portion 211 has
a diameter slightly smaller than a size of the drive stud 110 of the tool 10, so that
when the drive stud 110 of the tool 10 is inserted into the mounting portion 211 of
the tool display rack 20, the drive stud 110 of the tool 10 is urged on the holding
portions 213 of the mounting portion 211 to deform the holding portions 213 of the
mounting portion 211 As shown in Fig. 4. In such a manner, the deformed holding portions
213 of the mounting portion 211 are urged on the peripheral wall of the drive stud
110 of the tool 10 closely so as to clamp the drive stud 110 of the tool 10 rigidly
and stably, so that the drive stud 110 of the tool 10 is secured in the mounting portion
211 and cannot be rotated relative to the main body 21 of the tool display rack 20.
[0017] As shown in Fig. 1, the pressing member 22 is pivotally mounted on a second end of

neck portion 12 of the tool 10. Preferably, the passage 220 of the pressing member
22 has a side having two ends each formed with an oblique limit portion 221 to limit
a further movement of the neck portion 12 of the tool 10.
[0018] In such a manner, the neck portion 12 of the tool 10 is movable in the passage 220
of the pressing member 22 between the limit portions 221 of the passage 220, so that
the drive head 11 of the tool 10 is rotated relative to the main body 21 of the tool
display rack 20 to test the rotation angle of the drive stud 110 of the tool 10.
[0019] Accordingly, the main body 21 of the tool display rack 20 is integrally formed with
the mounting portion 211, the elastic portions 212 and the holding portions 213, so
that the tool display rack 20 has a simplified construction, thereby decreasing costs
of fabrication. In addition, the holding portions 213 of the mounting portion 211
are deformed and urged on the peripheral wall of the drive stud 110 of the tool 10
closely so as to clamp the drive stud 110 of the tool 10, so that the drive stud 110
of the tool 10 is secured in the mounting portion 211 rigidly and stably. Further,
the drive stud 110 of the tool 10 is closely secured on the mounting portion 211 and
cannot be rotated relative to the main body 21 of the tool display rack 20, so that
the drive head 11 of the tool 10 is rotated relative to the main body 21 of the tool
display rack 20 to test the rotation angle of the drive stud 110 of the tool 10 exactly.
Further, the passage 220 of the pressing member 22 has a side having two ends each
formed with an oblique limit portion 221 to increase the testing travel of the tool
10, so that the rotation angle of the drive stud 110 of the tool 10 is tested more
exactly.
[0020] Referring to Fig. 5, the mounting portion 211 is provided with three elastic portions
212 and three holding portions 213.
