Field of the invention
[0001] The invention relates to a tack device, more particulary to a tack device for multi-purpose fastening tool.
Background and Prior Art
[0002] Referring to FIG. 1,2,3,and 4, a conventional tack device includes a stationary part, a slidable part, a fastener-impelling plunger, and a first and second cover plate 22 23. The elongated nose plate16 has opposite front and rear faces 163 165, and extends in a vertical direction from the distal end166 in the slidable part 20. The second cover plate 22 is mounted to the front face 231 of the first cover plate 23 that is also mounted to the front face of elogated nose plate 16 to define a fastener-impelling track 162 therebetween. The first and second cover plates are coupled to the stationary part 14 by welding such that the fastener-impelling track 162 is in alignment with the stationary part 14.The fastener-impelling plunger 15 that drivers and discharges a fastener from which proximate to the first cover plate 23 and on the elongated base 12 ,is inserted between the first cover plate 23 and the front face 163 of stationary part 14 therebetween, and goes through from downwardly from distal end that forms a fastener-impelling track 162 to the discharging end 168. The fastener-supporting members 18 extending rearwardly from the rear face of elongated nose plate 16 in the transverse direction are disposed on the elongated base 12 and inside of the elongated rails 13 of slidable part 20 and are received in the inner space 144 of stationary part 14 and are in spatial communication with the stationary part 14 when cooperating with the fastener-holding members 146 and peripheral wall 145, to define the fastener-impelling track 162 of elongated nose plate 16 therebetween. A plurality of inverted U-shaped staples 8 are perfectly covered on the fastener-supporting members 18 , and slidable in the inverted nail-receiving channel and inverted staple-receiving channel 27 28 that are formed with the spatial communication of the fastener-supporting members 18 of slidable part 20 and fastener-holding members 146 of stationary part 14.(SEE FIG. 2). A plurality of inverted nails are disposed and slidable in the conveted nail-receiving channel 27 of slidable part 20 ,that received in the straight branch portion for nail 143 of stationary part 14 and discharged by the fastener-impelling plunger 15 on the front face 163 of elongated nose plate 16. (SEE FIG.3). A urging part 17 of slidable part 20 includes bar 171, fastener-pushing member 175 and hook 172. The fastener-pushing members 175 of urging part 17 that are pulled by the hook 172 and that push a plurality of U-shaped staples 8 and nails 9 by the bar 171 are properly covering on the fastener-supporting members 18 of slidable part 20.(SEE FIG.5)
[0003] The conventional tack device is disadvantageous in that the inverted U-shaped staples 7 (SEE FIG.9); aren't slidable on the inveted nail-receiving channel 27 and staple-receiving channel 28 when using a multi-purpose fastening tool according to the above descriptions, which is mainly because the side thickness and crown size are a bit different between the U-shaped staple 8 and U-shaped staple that fixed the cable. Thus, for a same conventional multi-purpose fastening tool, the worker can not operate successfully to load and fasten the U-shaped staples 8 and U-shaped staples 7 and nails 9 at the worksite and which results in undesirably increasing the cost of construction and non-convenient bringing different machines.

[0004] Therefore, the object of this invention is to provide a tack for a multi-purpose fastening tool which can overcome the aforementional disadvantages of the convenrtional tack device.
[0005] Accordingly. A tack device of present invention includes a stationary part, a fastener-impelling plunger, a slidable part.The stationary part has a straight branch portion for nails receiving a plurality of inverted nails and a branch portion for U-shaped staples cooperates with the peripheral wall and fastener-holding members receivng a plurality of inverted U-shaped staples, and has the first and second cover plates respectively includes a converted U-shaped flute, are in alignment with the front face of the stationary part in a vertical direction ; The slidable part includes elongated nose plate has opposite front and rear faces, extending in the vertical direction , and elongated base extending rearwardly from the rear face in the transverse direction, and urging part extending rearwardly from elongated nose plate in transverse direction and are perfectly covering on the fastening-supporting membersThe elongated nose plate has U-shaped staple impelling track,U-shaped staple impelling track and nail-impelling track respectively for a plurality of U-shaped staples, U-shaped staples and nails being discharge; and has a Hign-Low gap called "H"between the flat of nail impelling track and U-shaped impelling track, which is about 0.3-0.5mm and a Hign-Low gap called "2H"between the flat of U-shaped staple-impelling track and U-shaped staple- impelling track,which is also about 0.3-0.5mm. The elongated base extending rearwardly from the elongated nose plate in transverse direction, which has the fastener-supporting members and elongated rails formed with the right and left grooves therebetween, and has elongated projection to cooperate with the the fastener-supporting members that formed with nail passage and U-shaped staple passage thereinto. The urging part extending rearwardly from the elongated nose plate in transverse direction, which includes bar, hook and pushable bar together with fastener-pushing members and cooperates with the fastener-supporting members to define the nail passage and U-shaped staple passage;The fastener-impelling plunger drives downwardly from the distal end to the discharging end of slidable part in the vertical direction, which is adapted to discharge the U-shaped staple through both left and right section and to discharge the nails through right section and the U-shaped staples through the middle section.There is a nail-discharging opening is disposed adjacent to distal end of elongated nose plate and that extends through the front and rear faces of elongated nose plate in the vertical direction ,which separates the total fastener-impelling_track into U-shaped staple-impelling track, nail-impelling track, and U-shaped staple-impelling track.
