When a workpiece needs to be supported by the support structure 20 on the other working surface 11, an external force is only required to be applied to the working table 10, so that the working table 10 can rotate relative to the base, and the switching between the two working surfaces 11 of the working table 10 can be realized.

The workpiece may be a front end module of a vehicle or other workpiece suitable for use in the trolley 100 of the present application. In the present embodiment, the structure of the cart 100 in the present application will be described with a workpiece as a front end module of a vehicle. The front end module of a vehicle refers to a carrier in front of the vehicle, which may integrate other functional components of the vehicle, such as a radiator panel in a cooling system.
