When the compression inner spring contacts the floating joint 13, the floating joint 13 moves upward together. When the floating joint 13 moves to a certain distance from the proximity switch 8, the proximity switch 8 sends information to the PLC. The PLC issues a command to proceed to the next function. Due to inertia and external forces, the fixed bracket 2 continues to descend with the device, and the device housing 1 also descends at the same time. Since there is a clearance fit between the device housing 1 and the fixed bracket 2, the device housing 1 also continues to ascend with the device until the downward movement ends. When the external force is eliminated, the spring acts and the pressure plate 11 and the device housing 1 are restored to their maximum distance. The utility model is easy to operate and ensures detection reliability.
