During the installation process, it is only necessary to use the sliding plate 10 to press the cable tightly into the first arc-shaped clamp 3, rotate the turntable 6 in the second limiting assembly, and then insert the movable wire clamp shell 2 into the support column 1. The first limiting assembly automatically limits the wire clamp shell 2, thereby completing the installation.
