Problems solved by technology
[0005] Due to the limitation of the height of a single pole, it is often necessary to add another pole to the pole to meet the normal use on site. However, if the connection between the pole and the pole is unstable, it will cause the construction workers to fall from the height. Falling in the air caused personal injury to the construction workers, and delayed the construction period, and the circuit could not be repaired in time, affecting normal use
