Wrench quick release apparatus and wrench quick release handle

摘要

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 protrudes out from the channel of the sleeve. The wrench unit is pivotally connected to the positioning unit and protrudes 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.

主权项

1. A wrench quick release apparatus, for engaging with a first plate and then engaging with a second plate, comprising:
a sleeve having a first end, a second end opposite to the first end, a channel in communication with 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 protruding 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 protruding out from the second end of the sleeve; a wrench unit comprising a wrench section and a pushing section connected to the wrench section, the pushing section being a column body and movably and pivotally connected to the activating end of the positioning unit, such that the wrench unit substantially rotates in two directions, the two directions being clockwise and anticlockwise, by 90 degrees to push the pushing section against the second end of the sleeve, thereby driving the positioning end and the positioning section of the positioning unit to protrude or retreat; and an elasticity unit fitted around the positioning unit, comprising an end pushed against the positioning unit and another end pushed against the sleeve; wherein, the second end of the sleeve is flat, the pushing section has a first contact surface and a second contact surface, the first contact surface and the second contact surface are flat, the second contact surface being connected to the first contact surface, the first contact surface being a lateral surface of the pushing section, the second contact surface being an end surface of the pushing section, the second contact surface being perpendicular to the first contact surface substantially, wherein a vertical distance from a point of pivotal connection of the pushing section and the activating end to the first contact surface does not equal a vertical distance from the point of pivotal connection to the second contact surface, wherein the first contact surface and the second contact surface are movably pushed against the second end of the sleeve.
