It is especially used in electric poles, among which electric poles are also mainly square poles. The grounding method is generally to connect the copper stranded wire from the top of the pole to the grounding electrode. This method not only slows down the construction progress, but also affects the overall appearance of the pole. For example, as shown in the low-voltage pole grounding device with application number CN202022162228.4, the drop-pull grounding electrode is used to be fixedly set in the ground, and the supporting grounding wire is pulled and connected with the pole clamp to form a pulling grounding wire segment and an electrically connected wire segment. The pulling grounding wire segment is used to pull the pole clamp and the drop-pull grounding electrode, as well as a conductor for electrically connecting the drop-pull grounding electrode. The free end of the electrically connected wire segment is used to electrically connect to the grounded body, so that the supporting grounding wire and the drop-pull grounding electrode cooperate to form a grounding wire.

[0003] However, since the tension-bearing grounding conductor is exposed to the outside to stretch and fix the pole, it not only affects the overall appearance of the pole, but also affects the walking of pedestrians; in addition, the height of the lightning rod cannot be adjusted according to the usage scenario.
