[0031] In this embodiment, when the metal thermal compensator is impacted by an external force, the external force first contacts the protective plate 21, and the protective plate 21 is moved towards the metal thermal compensator due to the external force, and when moving, the connecting rod 25 is pressed, so that one end of the connecting rod 25 drives the fixed block 23 to move along the sliding rod towards the middle of the protective plate 21, and at the same time, the second buffer spring 27 arranged on the sliding rod buffers the impact force on the fixed block 23 and the protective plate 21, preventing the fixed block 23 from rapidly impacting the limiting plate 26 and causing damage, so that the external impact force is blocked and buffered by the protective plate 21 and the second buffer spring 27, and the metal thermal compensator is not affected, and the bolts arranged on the side surface of the fixed block 23 on the second guide rod 24 can fix the fixed block 23 on the second guide rod 24 to prevent rotation.
