[0002] When the automobile factory produces complete vehicles, there are many types of power, and the power of almost every model is different. Generally, during the assembly process, each engine or gearbox can only use the corresponding power support.

[0003] At present, the power support is almost always connected to the tray by bolts. When replacing the power support, the fixing bolts of the power support need to be removed and then replaced with another power support. It is time-consuming and inconvenient.

[0004] In the patent document with publication number CN218478233U, a pallet quick replacement device is disclosed. The device arranges a support mechanism and a cross-shaped through slot on a support table, and arranges a limit assembly at the concave corner of the cross-shaped through slot, so that the pallet can be placed above the cross-shaped through slot in a vertical or horizontal manner. When the device is set to switch between the two processing modes, there is no need to disassemble and assemble some parts, and it is only necessary to adjust the stacking method of the pallet accordingly. The operation is simple, time-saving and labor-saving, shortens maintenance time, improves production efficiency, and reduces labor costs, and the use effect is better.

[0005] However, the convenience of the device for replacing trays needs to be improved.

[0006] If the power support is switched by using a pressure claw fixing method, a lot of time can be saved. The present invention uses a pressure claw fixing method to switch the power support. Utility Model Content
