This creation relates to a technical field related to transportation equipment, especially a quick release used for connecting components of bicycles, which is assembled through a locking shaft and can be detached from a manipulation tool such as a quick release handle.

According to the bicycle, the quick release group is used in many parts to achieve the function of connecting the components to the frame, such as the rear axle connecting the end of the chain fork, or the tight connection between the seat tube and the seat tube. There are different forms of quick release currently. Due to the open groove design of the rear fork which is different from the traditional hook claw, a perforated hole is formed at the end of the rear fork to allow the quick release shaft (also known in the industry as: The through shaft) can be passed through the hole, and it can be tightened with the screw lock.

For example, the new patent case of Certificate No. M589150 "Thread Replacement Structure of Bicycle Axles" <hereinafter referred to as: Reference Case> shows that the quick release is in the combination structure of the quick release handle and the shaft, and one end of the shaft is the driving end. , the driving end has an embedded portion with a larger outer diameter, the outer peripheral surface of the embedded portion is provided with a plurality of protruding teeth, the end surface of the driving end has a combined screw hole, and the quick-release assembly has a set portion and extends from the A handle part on one side of the sleeve part, one side of the sleeve part has a set of holes for matching the sleeve to be embedded on the embedded part, and the other side has a slot hole that penetrates into the sleeve hole for a combination bolt to pass through and screw lock at the end In the screw hole, the quick release assembly is combined with the driving end of the shaft rod, thereby driving the shaft rod to rotate axially.

However, because of the quick release component of the reference cited case, on the one hand, it is embedded in the embedded part of the shaft by means of a sleeve hole, and at the same time, the quick release component is screwed to the combination screw hole of the shaft by using a combination bolt. The shaft system is constantly connected; however, there are some problems:

1. Since the quick release assembly and the shaft are in a fixed connection state, if there is a space limitation in the operating environment, it will cause a block on the path of the full circumference rotation of the quick release shaft, so that the quick release shaft cannot be fully rotated. The shaft is rotated and tightened or loosened, and the operation is obstructed.

2. Although the quick-release shaft is embedded with the sleeve hole in the embedded part of the shaft, it still requires a screw-lock tool to fasten the combination bolt and screw-lock quick-release assembly and the shaft screw, which increases the operation time and does not have the ability to operate quickly. advantage.
