Through the cooperation of the guide rod 10 and the movable block 4, the movement of the movable block 4 is guided and limited, thereby improving the stability of the movement of the movable block 4. After the knob 8 moves to a suitable position, a rubber sleeve adapted to the knob 8 is embedded outside the knob 8. At this time, the knob 8 will not continue to rotate without external interference, and at the same time, the gap between the knob 8 and the operating slot 9 is closed, thereby reducing the possibility of debris generated during the stamping process entering the operating slot 9 and affecting the operation;

To adjust the axial height of the punch 6, the staff slightly loosens the A nut 16 and the B nut, and manually pushes the moving block 17. The movement of the moving block 17 will drive the guide column 21 and the B nut of the integrated structure to move. The cooperation between the horizontal waist hole 20 and the guide column 21 guides the movement of the moving block 17. During the movement of the moving block 17, the adjustment plate 11 and the right clamping plate 12 move in the vertical direction through the cooperation between the A inclined surface 18 and the B inclined surface 19. After moving to the appropriate position, the staff rotates the A nut 16 and the B nut again, and the A nut 16 and the B nut come into contact with the rubber ring plate 22 and the ratchet, thereby fixing and connecting the moving block 17, the adjustment plate 11 and the mounting block 5.

According to the position of the punch 6, the right clamping plate 12 can be selected to be placed on the left side or head side of the adjustment plate 11 to further improve the utilization rate of the device. This is the use process of the punch seat that can fine-tune the position of the punch. At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
