[0023] In the utility model, the clamping mechanism includes a plurality of elastic card plates 3, and the plurality of elastic card plates 3 are evenly distributed on one side of the shell 1. The circumferential outer wall of the shell 1 is symmetrically distributed with a plurality of slide bars 2. One end of the plurality of slide bars 2 is fixed with a moving ring 4 by bolts, and the moving ring 4 is in contact with the elastic card plate 3. The moving ring 4 squeezes one end of the elastic card plate 3 to move toward the cable, clamps and fixes the cable, and makes the fixing effect of the cable better, avoids the cable from sliding outward, and improves the fixing effect of the cable. A linkage component for driving the moving ring 4 to move is provided on the top of the shell 1.
