The direction of force applied by one first reset elastic piece 137 to the limiting swivel 134 is opposite to the direction of force applied by the other first reset elastic piece 137 to the limiting swivel 134, so that when the limiting swivel 134 is forced by external force, the limiting swivel 134 is restored to the initial state through the two first reset elastic pieces 137 under the action of removing the external force after the limiting swivel 134 rotates. In one embodiment, one of the first restoring springs 137 is coupled to one of its radial protrusions 136, and the other first restoring spring 137 is coupled to the other radial protrusion 136; one end of the first restoring elastic member 137 is connected with the radial protrusion 136, the other end of the first restoring elastic member 137 is connected with the mounting base, and the first restoring elastic member 137 is a tension spring; when the first rotating shaft 132 rotates, one tension spring is lengthened, the tension is increased, the other tension spring is shortened, the tension is reduced, and after the external force is removed, the first rotating shaft 132 finally returns due to the fact that the tension at the two ends of the limiting rotating ring 134 is different in size, the tension of the two tension springs is equal, and the directions of the tension springs on the radial protrusions 136 are the same; the rotation angle range of the first rotation shaft 132 is ±7.5°.
