Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
example (b):
referring to fig. 1, the present embodiment provides an electric pole grounding structure for reducing the risk of ground wire damage; it includes the pole body 1 of the electric pole; a plurality of hoops 2 are arranged on the rod body 1; a guide groove 1A is formed on the rod body 1; the guide groove 1A is arranged along the length direction of the rod body 1, and the grounding piece 3 is placed in the guide groove 1A; a movable auxiliary pressing piece 4 is also arranged on the rod body 1; the movable end of the auxiliary pressing member 4 is attached to the outer end face of the grounding piece 3.
