Under the action of the punching tool 53, it is convenient to perform the perforation operation on the film.

[0018] Furthermore, the air chamber 5 acts above the bearing plate 2 through the mounting plate 3. The cross-section of the pressure rod 51 is "T" shaped. Through the connection between the air chamber 5 and the mounting plate 3, and the connection between the mounting plate 3 and the screw 31, the support effect of the air chamber 5 at the position of action is achieved.

[0019] Furthermore, the support blocks 52 are distributed in two groups on both sides of the pressure rod 51. The drilling tool 53 is connected to the support blocks 52. The pressure rod 51 is slidably connected to the support blocks 52 through the adjustment groove 55. Through the connection between the air chamber 5 and the pressure rod 51, the support control effect of the drilling tool 53 is achieved under the connection of the pressure rod 51 and the support blocks 52.

With the connection of the support block 52 and the punching tool 53, the punching operation of the film is completed. Under the action of the extension spring 91, when the solenoid valve 81 performs the air release operation, the pressure rod 51 is reset in the air chamber 5. When it is necessary to adjust the position of the punching tool 53, the adjusting rod 57 is rotated to change the position of the support block 52 on the pressure rod 51, thereby improving its application range and performance. With the connection of the connecting cover 54 and the air supply pipe 6, the passage of the solenoid valve 81 and the air supply pipe 6 are connected.
