The cooperation of the parts makes the clamping plate 34 pop out outward, and the staff holds the control rod 310 to pull out the clamping assembly 3. At this time, the switch assembly 2 can be removed. When installing, the reverse operation can be performed. When the wire 4 needs to be removed, the threaded rod 1 54 is rotated and removed to remove the threaded rod 1 54, and then the threaded rod 2 55 is rotated. The threaded rod 2 55 rotates on the arc plate 52, and the threaded rod 2 55 drives the arc pressure plate 53 to move. After the arc pressure plate 53 is away from the wire 4, the arc plate 52 is pulled outward, and the arc plate 52 moves along the limit rod 51. The wire fixing assembly 5 leaves the wire 4. At this time, the wire 4 can be taken out and removed normally. When it needs to be fixed, the reverse operation can be performed.
