A plurality of connecting rods 22 are arranged between the first retaining ring 20 and the second retaining ring 21. The second retaining ring 21 and the first retaining ring 20 can press the workpiece against the top surface of the support platform 11. The bottoms of the first retaining ring 20 and the second retaining ring 21 are both removable contact bodies 30. The first retaining ring 20 and the second retaining ring 21 are both annular structures. The inner diameter of the first retaining ring 20 is greater than the outer diameter of the second retaining ring 21. An annular punching channel is formed between the first retaining ring 20 and the second retaining ring 21. A plurality of holes are provided on the top surface of the support platform 11, and the punching channel is opposite to the holes. The connecting rod 22 forms a rectangular rod structure. The two ends of the connecting rod 22 are fixedly connected to the circumferential surfaces of the first retaining ring 20 and the second retaining ring 21, respectively. The holes on the top of the support platform 11 are staggered, and a cross bar is fixedly connected to the inner circumferential surface of the second retaining ring 21. An elastic member is provided on the top of the cross bar. The elastic member includes an elastic telescopic rod but is not limited to the elastic telescopic rod. The elastic member connects the cross bar to the connecting seat 12. In this scheme, an elastic member is installed at the bottom of the connecting seat 12. The elastic member takes the elastic telescopic rod as an example. The cylinder of the elastic telescopic rod is fixedly connected to the bottom of the connecting seat 12, and the cross bar is fixedly connected to the output shaft of the elastic telescopic rod. As the connecting seat 12 descends, the first retaining ring 20 and the second retaining ring 21 press the workpiece against the top surface of the frame 10. The punching channel formed between the first retaining ring 20 and the second retaining ring 21 is used to avoid the punch 13. Before the punch 13 contacts the workpiece, the workpiece is pressed and limited by the first retaining ring 20 and the second retaining ring 21. When the punch 13 punches, the first retaining ring 20 and the second retaining ring 21 can limit the deformation of the punching position of the workpiece, thereby ensuring the limiting effect and punching effect on the workpiece, which helps to improve product quality.

As the connecting seat 12 descends, the first retaining ring 20 and the second retaining ring 21 press the workpiece against the top surface of the frame 10, and the punching channel formed between the first retaining ring 20 and the second retaining ring 21 is used to avoid the punch 13. Before the punch 13 contacts the workpiece, the first retaining ring 20 and the second retaining ring 21 are used to press and limit the workpiece.
