Patent ID: 8857238

Claim:
A method for manufacturing a quick release axle assembly, comprising: a first step of preparing an elongate bar having a circular shape; a second step of pressing the elongate bar to form two mounting portions on two opposite ends of the elongate bar, at least one elongate groove between the two mounting portions, and a projection on a periphery of the at least one elongate groove; a third step of cutting the elongate bar to remove the projection from the periphery of the at least one elongate groove of the elongate bar; a fourth step of dieing the elongate bar to form a first external thread on one of the two mounting portions of the elongate bar and a second external thread on the other one of the two mounting portions of the elongate bar so as to produce an axle which includes the two mounting portions, the at least one elongate groove, the first external thread and the second external thread; a fifth step of providing a surface treatment on the axle to enhance toughness and hardness of the axle; a sixth step of providing two elastic members on the two mounting portions of the axle respectively; a seventh step of providing a fixing member which is locked onto the first external thread of the axle and abuts one of the two elastic members; a eighth step of providing a quick release device which is locked onto the second external thread of the axle; and a ninth step of providing a pressing member which is mounted the second external thread of the axle and biased between the quick release device and the other one of the two elastic members.
