[0032] When the wire needs to be installed and connected, the wire is wound and sleeved on the circumferential surface of the mounting column 4, and then the force block 7 and the clamping plate 6 are pulled downward by the pull-back of the pull-back spring 10, and the wire is clamped between the clamping plate 6 and the flexible copper bus 1 to complete the connection and installation of the wire. When the wire needs to be removed, the clamping plate 6 is pushed upward, and when the clamping plate 6 rises to the maximum, the clamping block 19 is pushed and clamped into the clamping groove 18 by the elastic push of the push spring 15, and the position of the clamping plate 6 is temporarily fixed, and then the wire is taken from the circumferential surface of the mounting column 4, which is convenient for personnel to remove the wire.
