Abstract:
1. A quick release structure for a bicycle comprising: a locking rod, a driving post, a positioning member, a connecting protrusion, and a fixing lever; the driving post being in connection with the connecting protrusion and being mounted in the fixing lever, the driving post being also fixed into the locking rod, and the locking rod including external threads formed on a first end thereof and screwing with a bicycle frame; the locking rod also including a threaded orifice defined on a second end thereof, and the threaded orifice having a polygonal groove formed therein; the threaded orifice of the locking rod including a screw bolt with a through hole, the screw bolt inserting through the positioning member, and the driving post inserts through the through hole of the screw bolt, the driving post including a polygonal head for matching with the polygonal groove, such that the fixing lever drives the driving post to move forward so that the polygonal head of the driving post moves into the threaded orifice to retain with the polygonal groove of the locking rod, thus driving the locking rod to rotate, or the fixing lever drives the driving post to move backward so that the polygonal head of the driving post removes from the polygonal groove of the locking rod, and the locking rod is not rotated.
