In the working process, as the number of wires to be threaded is large, the friction force between the threading pipe and the wires is large in the threading process, workers often perform brute force construction due to unsmooth threading, so that the phenomena of knotting of a plurality of groups of wires and abrasion and skin breaking of the wires and the 86-type bottom box occur at the pipe orifice junction box, and the workers are required to finish and assist in threading the plurality of groups of wires at the 86-type bottom box at any time. The whole process consumes a great deal of time and physical strength, which not only causes time waste, but also affects construction efficiency.
