Two limiting plates 18 are symmetrically fixedly connected to the top of the base 1. The outer walls of the two limiting plates 18 are slidably connected with sliders 19. One end of the two sliders 19 is fixedly connected to a fixed plate 20. The inner walls of the two fixed plates 20 are slidably connected with sliding shafts 21. The bottoms of the two sliding shafts 21 are fixedly connected with lower pressure plates 23. The outer walls of the two sliding shafts 21 are sleeved with second springs 22. The tops of the two sliding shafts 21 are fixedly connected with limiting blocks 24. A linkage assembly is provided between the two sliders 19 and the motor 25.
[0024] Through the above technical scheme, the anti-stone chip protective film is placed on the base 1, and the motor 25 is started to drive the threaded rod 4 to rotate, so that the sleeve 5 moves downward, the fixed frame 6 moves downward, and the tool mold frame 8 moves downward. After the fixed frame 6 moves downward, the tool mold frame 8 is firmly connected to the fixed frame 6 through the cooperation of the limit assembly, and the anti-stone chip protective film can be cut into a required shape through the tool mold frame 8. At the same time as the motor 25 is started, the two sliders 19 are driven downward by the linkage assembly, so that the two fixed plates 20 move downward, and the two lower pressure plates 23 move downward. Through the two second springs 22, the lower pressure plate 23 is pressed against the top of the anti-stone chip protective film to prevent the anti-stone chip protective film from moving during the punching process. After the punching is completed, the fixed frame 6 is retracted upward, and the limit assembly is unlocked, which is convenient for removing the tool mold frame 8 from the bottom to the top, and convenient for replacing the tool mold frame 8 with different punching shapes.

The tops of the two clamping blocks 10 are provided with inclined grooves for cooperating with the push rods 13.
[0026] Through the above technical solution, after the fixed frame 6 moves downward, the two push rods 13 move out of the fixed frame 6, and under the action of the two first springs 11, the two card blocks 10 are pushed to move, so that the two card blocks 10 enter the two card slots 12 respectively, and the tool mold frame 8 is firmly connected to the fixed frame 6 through the limiting of the two card blocks 10. After the punching is completed, the fixed frame 6 is retracted upward. At this time, the two push rods 13 are inserted into the fixed frame 6, and the bottoms of the two push rods 13 are respectively pressed against the inclined grooves at the tops of the two card blocks 10, pushing the two card blocks 10 to move, so that the two card blocks 10 are respectively moved out of the two card slots 12. After the limiting of the two card blocks 10 is lost, the tool mold frame 8 can be removed from the bottom to the top.

After the two clamping blocks 10 lose their limit, the tool mold frame 8 can be removed from the bottom to the top, which is convenient for replacing the tool mold frame 8 with different punching shapes.
