Thus, the clamping plate 603 and the pressing frame 608 together clamp and position the die steel on one side of the support plate 601. After that, the displacement plate 4 continues to move. The displacement of the displacement plate 4 contacts the sliding plate 611, pushing the sliding plate 611 to be displaced, squeezing the second spring 612.
