Abstract
A quick release structure for a bicycle includes a locking rod fixed securely, wherein the locking rod has a polygonal groove formed therein. The driving post of the locking rod includes a polygonal head. As desiring to lock the locking rod on the bicycle frame or to unlock the locking rod from the bicycle frame, the polygonal head of the driving post retains with the polygonal groove of the locking rod so as to rotate the locking rod. When the locking rod is rotated tightly, the polygonal head of the driving post removes from the polygonal groove so that the locking rod cannot be rotated, and the driving post of the locking rod does not drive the locking rod to rotate loosely after vibration, thereby obtaining positioning safety.
