Thermal resistor protection device with damping function

The invention relates to a thermal resistor protection device. The invention relates to a thermal resistor protection device with a damping function. The device comprises a testing device and a damping device arranged in the middle of the testing device, the testing device comprises a testing mechanism, the testing mechanism comprises a testing rod, and a positioning structure is arranged at the position, close to the middle, of the outer wall of the testing rod. Before the test rod is installed, the spiral cylinder, the sleeve and the insertion rod protect the test rod, meanwhile, the locking rod and the matching rod are linear, the test rod is prevented from being damaged when the test rod falls on the ground or is impacted by the outside, and compared with a common thermal resistor installation method, the thermal resistor is better protected before the thermal resistor is installed; after the spiral cylinder is installed, the damping spring and the lifting rod are matched to filter vibration borne by the
