[0001] The utility model relates to the technical field of sprocket seat assembly, in particular to a clamping mechanism for assembling a motorcycle sprocket seat. Background Art

[0002] During the assembly process of the existing motorcycle sprocket seat, the sprocket seat needs to be installed and fixed, but the existing device has certain disadvantages. For example, the device described in Publication No. CN219152697U includes a bottom box and a placement seat. The placement seat is installed in the middle of the top side of the bottom box. The placement seat is provided with a limiting groove for limiting the sprocket seat and a plurality of bolt holes for placing bolts. The bottom box is symmetrically provided with through grooves. An L-shaped claw is rotatably installed in the through groove, and a rubber pad is installed on the claw.

[0003] Although the above device pre-fixes the threaded assembly and reduces the number of times the sprocket seat is turned over later, it is operated at a single station and there is a large time interval between loading and unloading, resulting in poor continuity of the device and reduced assembly efficiency.
