In addition, the inner surface of the four clamping arc plates 4 is provided with an insulating non-slip pad (not shown in the figure), and the insulating non-slip pad can prevent the cable from sliding in the clamping cavity 3.

[0024] The linkage pull and pressure expansion cavity mechanism 5 is arranged on the cable mounting ring 1 for linkage and downward pressing of the two clamping arc plates 4 to expand the clamping cavity 3 so as to facilitate the cable to pass in. The linkage pull and pressure expansion cavity mechanism 5 comprises a pull rod 503, a fixed sleeve 501 and two pull ropes 504. A sliding groove 101 is formed in the thickness direction of the wall of the cable mounting ring 1, and the sliding groove 101 is arranged between the two clamping arc plates 4. The pull rod 503 is slidably arranged in the sliding groove 101.

[0025] Two arc grooves 505 are formed in the wall of the cable mounting ring 1 and are communicated with the sliding groove 101. One end of the arc groove 505 is arranged on the groove wall of the sliding groove 101, and the other end of the arc groove 505 is arranged on the inner circumferential wall of the cable mounting ring 1 at the bottom of the corresponding side spring 2.
