[0035] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 5As shown, a hook structure includes a left hook and a right hook, wherein the left hook includes a left mounting claw 1 and a left mounting frame 2, and the right hook includes a right mounting claw 3 and a right mounting frame 4.

[0037] At the same time, the left mounting claw 1 and the right mounting claw 3 are used to connect with the rear axle, and the left mounting frame 2 is used to connect with the rear upper fork 7 and the rear lower fork 8, and the right mounting frame 4 includes a mounting frame 1 41 and a mounting frame 2 42, and the mounting frame 1 41 is used to connect with the rear upper fork 7 and the connection with the rear upper fork 7 is plug-in, and the mounting frame 2 42 is used to connect with the rear lower fork 8, and the mounting frame 1 41 and the mounting frame 2 42 are connected through the right mounting claw 3.

[0038] Therefore, in actual use, by setting the hook claw as a detachable mounting claw and mounting frame, different mounting claws can be replaced to adapt to different models, and the replacement can also be partial replacement. Secondly, the right mounting frame 4 is also detachable and plug-in, so as long as the connection between the mounting frame 41 and the right mounting claw 3 is removed and the mounting frame 41 and the rear seat fork 7 are separated, the transmission part can be removed. Compared with the existing removal of two connections, it is more convenient to remove one connection.

[0039] The connection method of the rear axle is that the bottom of the left mounting claw 1 and the right mounting claw 3 are grooved for the rear axle to be installed, and the connection between the utility model and the upper fork 7 and the rear chain fork 8 is plug-in, that is, the connection between the left mounting frame 2 and the upper fork 7 and the rear chain fork 8 is plug-in, and the connection between the mounting frame 2 42 and the rear chain fork 8 is plug-in.
