[0031] Put the steel plate between the vertical plates 5 and 5, adjust the position of the steel plate above the bottom plate 1 to a suitable state, turn on the electric telescopic rod 6 so that the end of the extension rod extends to push the rack 7 forward, and the forward movement of the rack 7 drives the gear 8 to rotate, and the gear 8 drives the pressure block 9 to rotate, and the pressure block 9 presses the lower pressure plate 10 downward. At this time, the spring 11 is squeezed and elastically deformed, and the elastic pad at the lower end of the spring 11 fits tightly against the upper surface of the steel plate to fix the position of the steel plate to prevent the steel plate from being touched and displaced, resulting in errors.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the connecting plate 12 and the protective plate 13 are both slidably connected in the cavity opened inside the bottom plate 1, and the protective plate 13 is rotatably connected to the inner side of the connecting plate 12.
