[0025] By adopting the above technical solution, the tightening screw 62 is rotated to rotate and move along the fixing sleeve 61. The movement of the tightening screw 62 drives the moving rod 63 to move along the inside of the fixing sleeve 61 under the action of the connecting piece 65. The movement of the moving rod 63 drives the tightening block 64 to move. When the tightening block 64 fits the side wall of the power tower, the rotation of the tightening screw 62 is stopped.

When the tightening block 64 is in contact with the side wall of the power tower, the tightening screw 62 is stopped from being rotated. Under the action of the tightening block 64, the power tower can be tightened and fixed, thereby ensuring the stability of the connection between the entire device and the power tower, and then under the action of the rotating mechanism 1, the stabilizing mechanism 2 and the support plate 3 are rotated and unfolded, and the support plate 3 is used to support the stabilizing mechanism 2, and then the stabilizing mechanism 2 is used to support and fix the insulator, thereby improving the stability of the insulator.
