The power connection method of each electrical device is an existing mature technology, which is a well-known technology for people in this field and will not be described in detail here.

[0036] Two sliders 12 are provided on the one-way screw 11, so as to facilitate the subsequent loading and unloading operations of the materials;

[0037] When in use, first place the material on the placement seat 3, then place the placement seat 3 on the slider 12, then start the one-way screw 11, so that the one-way screw 11 drives the slider 12 to slide, and at the same time the slider 12 slides along the arc plate 14, so that the arc plate 14 guides the slider 12 while blocking the one-way screw 11;
