The closing rod 42 and the extrusion plate 4 are both located inside the installation groove, and the closing rod 42 is used to close the cable inlet 3, thereby preventing the cable from escaping from the cable hole 2. A spring groove 43 is opened on the side wall surface of the closing rod 42, and the inner wall of the spring groove 43 and the inner wall of the hinge groove 41 are both installed with a rotating shaft 44, and the surfaces of the two adjacent rotating shafts 44 are fixedly connected with thrust springs 45, which are compressed into the spring groove 43 by the thrust spring 45, thereby folding and contracting the closing rod 42 and the extrusion plate 4.

[0025] By setting up an improvement on the positioning plate 1 and opening the surfaces of multiple cable holes 2 to facilitate the insertion of cables into the cable holes 2, a wire clamping mechanism is installed in the positioning plate 1, and the closing rod 42 in the wire clamping mechanism is used to deflect the axis around the positioning plate 1, and when it is rotated outward, the wire inlet 3 on the surface of the positioning plate 1 is closed, thereby facilitating the prevention of the cables from falling out. Moreover, after the closing rod 42 is deflected out, the extrusion plate 4 is deflected into the cable hole 2, and while the cable is pressed tightly, the closing rod 42 is effectively prevented from retreating into the installation groove, thereby improving the sealing effect of the cable hole 2.

[0026] In order to drive the closing rod 42, a rotating groove is provided on the side wall surface of the positioning plate 1, and the inner wall of the rotating groove is rotatably connected to a control cylinder 46 through a bearing, one end of the control cylinder 46 is located outside the rotating groove, and a connecting rod 47 is fixedly connected to the outer wall surface of the control cylinder 46, and a connecting groove 48 is provided on the side wall surface of the positioning plate 1.
