The outer wall of the connecting air pipe 11 is fixedly connected to the electromagnetic valve induction switch 12. The magnetic valve sensing switch 12 is used to control the on and off of the gas, thereby achieving precise control of the action of the clamping component, such as loosening or clamping the workpiece at the appropriate time. The detection component includes a detection rod 20, which is directly involved in the detection process of the puncture strength. During the test, it contacts the workpiece and applies force.
