[0044] In actual operation, when this device is used, the plate to be stamped is manually placed on the top back side of the rectangular mold 1, and the bidirectional asynchronous motor 3 426 is energized. When the bidirectional asynchronous motor 3 426 is energized, it is fixedly installed between the transmission belt 424 between the output end, thereby driving the transmission belt 424 to rotate.

When the sprocket 26 rotates, it engages with the outer toothed disc 22 to rotate the toothed disc 22. When the toothed disc 22 rotates, it is fixedly installed with the top lifting screw 25, so that the lifting screw 25 can rotate. When the lifting screw 25 rotates, it is threadedly installed with the threaded sleeve 24, so that the threaded sleeve 24 can be lifted and lowered. In this way, the height can be adjusted by changing the distance between the base 23 and the rectangular mold 1, which can make the processing more convenient.
