The sliding component is installed on the support, and a welding layer is arranged in the sliding direction. One end of the swinging rod can swing by taking the rotating shaft as a fulcrum, and the end part is also provided with a first propping arm for propping against a key switch outside the bracket, and the other end of the swinging rod is arranged on the sliding component. When the welding layer is broken by surge, the sliding component is not blocked by the welding layer to start sliding, and the swinging rod is driven to swing, so that the first propping arm is separated from the key switch, and the key switch sends out a remote signaling signal.
