WRENCH QUICK RELEASE APPARATUS
A wrench quick release apparatus includes a sleeve, a positioning unit, a wrench unit and an elasticity unit. The sleeve includes a channel and an engaging section for engaging to a first plate. The positioning unit inserts in the channel of the sleeve, and includes one end inserted through the first plate and an opposite end extends out from the channel of the sleeve. The wrench unit is pivotally connected to the positioning unit and extends out from one end of the sleeve. The elasticity unit includes one end pushed against the positioning unit and an opposite end pushed against the sleeve. Accordingly, the wrench quick release apparatus is first engaged to the first plate through the sleeve and then engaged to or disengaged from a second plate to achieve a steady and quick assembly effect with minimal efforts in a convenient manner.
1 . A wrench quick release apparatus, for engaging with a first plate and then engaging with a second plate, comprising:
a sleeve, comprising a first end, a second end opposite to the first end, a channel connecting the first end and the second end, and an engaging section for engaging to the first plate;
a positioning unit, being a column body movably inserted in the channel of the sleeve, comprising a positioning end extending to the first end of the sleeve, a positioning section provided at the positioning end and for engaging to a positioning section of the second plate, and an activating end opposite to the positioning end and extending out from the second end of the sleeve;
a wrench unit, comprising a wrench section, and a pushing section connected to the wrench section and movably and pivotally connected to the activating end of the positioning unit, so as to give impetus to the positioning end and the positioning section of the positioning unit for extension and contraction when the pushing section is pushed against the second end of the sleeve by rotating the wrench unit; and
an elasticity unit, fitted around the positioning unit, comprising an end pushed against the positioning unit and another end pushed against the sleeve.
2 . The wrench quick release apparatus as claimed in claim 1 , wherein the pushing section of the wrench unit comprises a pivot groove and a pivot inserted through the pivot groove, the pivot groove is fitted around the activating end of the positioning unit, and the pivot is inserted through the activating end of the positioning unit.
3 . The wrench quick release apparatus as claimed in claim 1 , wherein the positioning section of the positioning unit is a positioning column inserted in the second plate.
4 . The wrench quick release apparatus as claimed in claim 1 , wherein the positioning section of the positioning unit is a threaded column fastened to the second plate.
5 . The wrench quick release apparatus as claimed in claim 1 , wherein the positioning section of the positioning unit is at least two elastic fastening bodies each comprising at its one side a protruding fastening section for fastening to the second plate.
6 . The wrench quick release apparatus as claimed in claim 1 , wherein the positioning section of the positioning unit is a hook for fastening to the second plate.
7 . The wrench quick release apparatus as claimed in claim 1 , wherein the engaging section of the sleeve is a press-in section for installing to the first plate.
8 . The wrench quick release apparatus as claimed in claim 1 , wherein the engaging section of the sleeve is a fastening section for fastening to the first plate.
9 . The wrench quick release apparatus as claimed in claim 8 , wherein the fastening section comprises a first screw thread at the channel and a fastening element fastened to the first screw thread, and the fastening element comprises a second screw thread matching the first screw thread; the engaging section of the sleeve first accommodates one side of the first plate and the fastening element then fastens another side of the first plate to fasten the second screw thread to the first screw thread.
10 . The wrench quick release apparatus as claimed in claim 1 , wherein the engaging section of the sleeve is a welding section for welding to the first plate.
11 . The wrench quick release apparatus as claimed in claim 1 , wherein the engaging section of the sleeve comprises a flare-in section for installing to the first plate.
12 . The wrench quick release apparatus as claimed in claim 1 , wherein the sleeve is not provided with the engaging section, and the first end of the sleeve is integrally formed on the first plate and the channel connects the first plate and the second end.
13 . The wrench quick release apparatus as claimed in claim 1 , wherein the pushing section of the wrench unit is movably and pivotally connected to the second end of the sleeve; so as to give impetus to the positioning end and the positioning section of the positioning unit for extension and contraction when the pushing section is pushed against the activating end of the positioning unit by rotating the wrench unit.
14 . The wrench quick release apparatus as claimed in claim 13 , wherein a wall of the second end of the sleeve is provided with two corresponding pivot sections, between which the pushing section of the wrench unit is movably and pivotally connected, and the pushing section is pushed against the activating end of the positioning unit.
