The limiting auxiliary mechanism 6 includes a docking buckle 61 fixedly connected to one end of the main line clamp 1, one end of the docking buckle 61 is fixedly connected to a connecting frame 62, one end of the connecting frame 62 is provided with a mounting groove 63, a corresponding piece 64 is placed on the inner side of the mounting groove 63, one end of the corresponding piece 64 is fixedly connected to a protective piece 66, the internal thread of the connecting frame 62 is connected to a small bolt 65, one end of the protective piece 66 is fixedly connected to a limiting piece 67, the upper end of the limiting piece 67 is fixedly connected to a fastening seat 68, the inner side of the fastening seat 68 is threadedly connected to a large bolt 69, the large bolt 69 passes through the interior of the limiting piece 67, the large bolt 69 is threadedly connected to the limiting piece 67, and the lower end of the large bolt 69 is fixedly connected to a clamping piece 610.
[0021] In this embodiment, a protective pad 611 is fixedly connected to the inner top of the limiting plate 67, a small bolt 65 extends to the inside of the corresponding plate 64, and the small bolt 65 is threadedly connected to the corresponding plate 64. The corresponding plate 64, the protective plate 66, and the limiting plate 67 are all arc-shaped. The axial lines of the docking buckle 61, the connecting frame 62, the corresponding plate 64, the protective plate 66, and the limiting plate 67 are located on the same straight line. The clamping plate 610 is located on the inner side of the limiting plate 67. The main material of the clamping plate 610 is rubber. The shape of the protective pad 611 is arc-shaped, and the main material of the protective pad 611 is rubber.
[0022] Specifically, the corresponding piece 64 is inserted into the mounting groove 63, and the small bolt 65 is screwed from the connecting frame 62 into the corresponding piece 64, so that the limiting piece 67 is limited to the outside of the wire body, and the limiting piece 67 clamps the wire body through the protective pad 611, and then the large bolt 69 is rotated to move the large bolt 69 in the fastening seat 68, and then the large bolt 69 pushes the clamping piece 610 to move, so that the clamping piece 610 contacts the wire body, so that the two sets of large bolts 69 pass through the clamping piece 610 respectively. The wire body is clamped, and the main wire clamp 1 and the auxiliary wire clamp 2 are confined at the specified position. By inserting the corresponding piece 64 into the installation slot 63, and then screwing the small bolt 65 from the connecting frame 62 into the corresponding piece 64, and finally rotating the large bolt 69 to push the clamping piece 610 to contact the wire body, the two sets of large bolts 69 can be used to clamp the wire body through the clamping piece 610. This can not only fix the main wire clamp 1 and the auxiliary wire clamp 2 in the specified position, but also reduce the risk of their displacement on the exposed wire body, thereby improving the overall safety.

The fixing seat 68 moves, and the large bolt 69 pushes the clamping piece 610 to move, so that the clamping piece 610 contacts the wire body, and the two groups of large bolts 69 pass through the clamping piece 610 to clamp the wire body, thereby limiting the main wire clamp 1 and the auxiliary wire clamp 2 to the specified position. By inserting the corresponding piece 64 into the installation groove 63, and then screwing the small bolt 65 from the connecting frame 62 into the corresponding piece 64, and finally rotating the large bolt 69 to push the clamping piece 610 to contact the wire body, the two groups of large bolts 69 can pass through the clamping piece 610 to clamp the wire body, so that the main wire clamp 1 and the auxiliary wire clamp 2 can be fixed in the specified position, and the risk of displacement on the exposed wire body can be reduced, thereby improving the overall safety.
