[0032] Further, the anti-loosening assembly 207 further comprises two positioning rods 207g for limiting the movable plate 207d, and the end of the positioning rod 207g is fixedly installed on the top of the inner cavity of the mounting box 207a.

[0033] The positioning rod 207g is used to limit the movable plate 207d, and two positioning holes for the positioning rod 207g are arranged on the outer side of the movable plate 207d. One end of the positioning rod 207g is inserted into the inner side of the positioning hole, and the movable plate 207d is limited by the positioning hole and the positioning rod 207g when moving.

[0034] Preferably, the bottom of the limiting plate 207c is inclined to the direction of the pulley 207f, and the surface of the pulley 207f is in contact with the inclined surface of the limiting plate 207c.

[0035] Further, the two sides of the bottom of the inner cavity of the mounting box 207a are provided with drainage grooves 207h, which are used for draining water in the inner cavity of the mounting box 207a.

[0036] The drainage groove 207h is used to drain the rainwater in the inner cavity of the mounting box 207a, so as to avoid the corrosion of the rainwater in the inner cavity of the mounting box 207a to the parts in the inner cavity of the mounting box 207a.

[0037] Specifically, the outer surface of the fixing nut 206 is provided with a clamping groove 208 matched with the clamping column 207e, and the size of the clamping groove 208 and the clamping column 207e is matched.

[0038] The size of the clamping groove 208 and the clamping column 207e is matched, so as to improve the stability of the clamping column 207e in the inner cavity of the clamping groove 208.

[0039] Further, the top of the second connecting plate 204 is fixedly provided with a connecting head connected with the suspension device on the tower.

[0040] In use, the first and second clamps 201 and 202 are closed to fix the outer cable 101, the first and second connecting plates 203 and 204 are installed together through cooperation between the mounting bolt 205 and the fixing nut 206 to fix the outer cable 101, the fixing nut 206 needs to be rotated to the horizontal direction, the mounting box 207a is fixedly installed on the outer side of the first connecting plate 203 through a screw, the limiting plate 207c is clamped on the outer side of the fixing nut 206, the end of the clamping column 207e is clamped in the inner side of the clamping groove 208, the fixing nut 206 is limited, the limiting principle is that when the fixing nut 206 is loose during use, the fixing nut 206 will rotate at a certain angle, which causes the fixing nut 206 to extrude the limiting plate 207c at the angle, so that the limiting plate 207c rotates, the inclined surface at the bottom end of the limiting plate 207c extrudes the pulley 207f, the pulley 207f transmits the extrusion force to the movable plate 207d, the movable plate 207d pushes the clamping column 207e to be clamped in the inner side of the clamping groove 208, the fixing nut 206 is limited, which can prevent the fixing nut 206 from being further loose, and when the clamping column 207e is clamped in the inner cavity of the clamping groove 208, the clamping groove 208 will react force on the clamping column 207e, preventing the clamping column 207e from being further clamped in the inner side of the clamping groove 208, and further preventing the movable plate 207d and the pulley 207f from moving, thereby preventing the limiting plate 207c from further rotating, improving the limiting effect of the limiting plate 207c on the fixing nut 206, and preventing the fixing nut 206 from being loose under the action of double limiting.

[0041] In summary, the anti-loose assembly 207 can be used to limit the fixing nut 206, solve the problem of loosening of the fixing nut 206 during long-term use, and improve the limiting effect of the optical cable.
