In order for your review board to have a better understanding of the creation, a preferred embodiment will be described in conjunction with the drawings, as detailed below:

Referring to Figures 2 to 6, the bicycle quick release shaft 20 is provided as a hollow round rod body having a rod through hole 21 therein. The shaft rod 20 is provided with a locking assembly 22 at one end and a rod at the other end. An inner sleeve 23 having an inner screw hole 231 is fixed in the through hole 21, and the inner sleeve 23 is located at a distance from the end edge of the rod through hole 21, so that the rod through hole 21 is formed at the outer end edge. An inner ring groove portion 24; The inner ring groove portion 24 can be embedded with a set of trays 25. The sleeve plate 25 is provided with a disk through hole 26 at the center, and one of the sleeve disks 25 is provided with a circular ring 27 at the axial end thereof, and the other axial direction thereof. A ring groove 28 is connected to the disk through hole 26, and the circular ring 27 of the socket disk 25 can be embedded in the inner ring groove portion 24 of the shaft 20; the ring groove 28 can be embedded with a thread. The outer surface of the cylinder 30 of the screw barrel 30 is provided with an external thread 31. The barrel of the screw barrel 30 has a through hole 32. One end of the screw barrel 30 is provided with a cylindrical ring 33. The other axial end is provided with a cylindrical groove 34 communicating with the through hole 32. The cylindrical protruding ring 33 can be embedded in the inner ring groove portion 24 of the shaft 20 or the ring groove 28 of the sleeve disk 25. The tube through hole 32 is formed with a bolt 35 having a driving portion 36 and an outer thread portion 37 through which the outer thread portion 37 passes, and through the disk through hole 26 or directly The through hole 21 is screwed into the inner screw hole 231 of the inner sleeve 23, so that the driving portion 36 of the bolt 35 is received in the cylindrical groove 34 and the screw barrel 30 is pressed and locked. With the shaft 20; by the above structure, the shaft 20 can be replaced differently And changing the length of the pattern effect.

The composition and function of the above embodiments are described in detail as follows: Please refer to Figures 2 to 6, the shaft 20 of the present invention selects a suitable screw cylinder 30 according to the frame screw hole specification, and when assembled, the screw barrel is assembled. 30, the cylindrical collar 33 is engaged with the inner ring groove portion 24 of the shaft 20 (as shown in FIG. 5), and the external thread 37 of the bolt 35 is inserted into and passed by the cylindrical groove 34. The through hole 32 is screwed into the inner screw hole 231 of the inner sleeve 23, and the cylindrical groove 34 is detached from the driving portion 36 of the bolt 35, and the bolt 35 can be screwed to the thread.
