[0023] The device is installed and used through the main board 1. Through the cooperation of the pressure control mechanism, the linkage plate 4, the mounting seat 5, the pressure plate 8 and the punch 6 are controlled to move up and down at the same time. The pressure plate 8 uses the extension of the connecting rod 7 to pre-contact and press the product during the downward movement. After pressing, the connecting rod 7 slides and the spring 9 around the connecting rod 7 rebounds. The thrust force allows the pressure plate 8 to maintain pressing while the punch 6 can continue to extend through the pressure plate 8 to punch the product. When the pressure plate 8 moves downward quickly, the multiple air guide holes 10 opened on its outer wall are used to guide the airflow to avoid a large airflow below it to push the product. The screw cap 11 can be rotated and detached, which is convenient for personnel to remove the connecting rod 7 and the pressure plate 8 and replace the fatigued spring 9.

[0024] Preferably, the pressure control mechanism includes a cylinder 12, a threaded joint 13, a threaded rod 14 and a screw block 16, the cylinder 12 is fixed to the outer wall of the main board 1, and the threaded joint 13 is fixed to one end of the telescopic shaft of the cylinder 12;

[0025] The cylinder 12 of the pressure control mechanism is the main power output component. A threaded joint 13 is installed at one end of the telescopic shaft of the cylinder 12 to cooperate with the connection of the cylinder 12 for subsequent transmission.

[0026] Preferably, the threaded rod 14 is threadedly connected to one end of the linkage plate 4, a thread groove 15 is provided at one end of the threaded rod 14, and one end of the threaded connector 13 is threadedly connected to the thread groove 15 of the threaded rod 14;

[0027] The threaded rod 14 is threadedly connected to the threaded joint 13 of the telescopic shaft of the cylinder 12 through the threaded groove 15 at one end thereof, so that the linkage plate 4 receives the control power, and the threaded rod 14 can be rotated and extended at one end of the linkage plate 4 to fine-tune the distance between the linkage plate 4 and the cylinder 12, thereby fine-tuning the drilling operation height.

[0028] Preferably, a screw block 16 is fixed to one end of the threaded rod 14;

[0029] The screw block 16 is used to facilitate personnel to rotate the threaded rod 14 to adjust it.

[0031] Through the cooperation of the slide rail 2 and the slider 3, the linkage plate 4 is more stable when moving up and down, and is not easy to deviate and affect the accuracy of the opening operation.

[0032] A specific application of this embodiment is: the soft material product that needs to be punched can be placed under the pressure plate 8, and the cylinder 12 of the pressure control mechanism is used to control the pressure plate 8 to move downward. When moving downward, the pressure plate 8 pre-presses the product around the punching position. During operation, the telescopic shaft of the cylinder 12 drives the linkage plate 4 to move up and down through the connection of the threaded joint 13 and the threaded rod 14, thereby driving the placement seat 5 and the pressure plate 8 to move up and down to complete the pressing operation. In the process of rapid downward pressing of the pressure plate 8, the multiple air guide holes 10 opened on its outer wall are used to reduce the downward airflow to prevent the soft material product such as a thin film from being blown by the downward airflow. When the placement seat 5 is controlled to punch downward, the punching knife 6 punches downward toward the operating hole of the pressure plate 8, and the punching knife 6 can pass through the operating hole of the pressure plate 8 through the cooperation of the connecting rod 7 and the spring 9 to punch the product pressed by the pressure plate 8.
