A positioning column 4 is provided at one end of the loading platform 2 close to the lower frame 1. The positioning column 4 is a frustum-shaped structure with a larger upper portion and a smaller lower portion. A positioning hole 5 matching the positioning column 4 is provided on the lower frame 1. It can be seen that the positioning hole 5 is also a conical hole. The positioning column 4 is arranged at the positioning In the hole 5, the conical structure has a self-centering effect, which facilitates the installation of the loading platform 2 and improves the installation efficiency. A first rolling mechanism is provided on the loading platform 2, and the first rolling mechanism is in rolling contact with the lower frame 1. Second rolling mechanisms are provided at both ends of the lower frame 1.
