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.
