When the contact plate 14 inside the connecting clamp 13 is squeezed into contact with the arm body 1, the movable part 18 compresses the buffer spring 17 in the buffer sleeve 16.

[0109] During use, the telescopic rebound force of the buffer spring 17 is used to leave a margin when clamping to avoid indentation on the arm body 1. Then, the through nails connecting the arm body 1 and the rod insulator body 9 are removed, and then the screw jack 4 is shaken to extend the telescopic rod 3, so that the arm body 1 moves to one side, so that the rod insulator body 9 is separated from the arm body 1. Then, a new rod insulator body 9 is replaced, and the screw jack 4 is shaken in the opposite direction to insert the arm body 1 into the bottle mouth of the rod insulator body 9.

[0110] Finally, the connection is fixed by nailing, and the operation is completed, so that the arm body 1 can be replaced without changing the original force direction and magnitude. The equipment replacement movement is small, which can improve the operation efficiency and the safety factor of the operator.

[0111] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
