At this time, the workpiece can be placed on the upper end surface of the lifting chassis 19. At this time, the clamping motor 14 is started to drive the clamping rotating shaft 20 to rotate, thereby driving the matching gear 25 to rotate, and then driving the clamping rotating shafts 20 at four places to rotate, so that the clamping moving blocks 13 at four places begin to move toward the center side, so that the clamping moving blocks 13 move toward the center.
