Preferably, the drive connecting rod may be a universal joint, a connecting joint, or a connecting rod. The function of the universal coupling is that when a person holds an electric tool to lift the material platform, he can stand on the side of the material platform or stand under the material platform. If the material platform is lowered to the ground, the electric tool can It is connected with the connecting part of the worm through the driving connecting rod from the side, which is very convenient to use.

The material platform is also provided with at least one pair of lower pulleys which are two pairs of lower pulleys, and the suspension device is provided with two pairs of upper pulleys corresponding to the lower pulleys one by one.

Preferably, the material platform includes a frame surrounded by plates or profiles, and a steel wire mesh is connected to the top of the frame.
