Description

Technical Field

[0002] Building electrical wiring is an important part of building electrical installation engineering. It involves passing insulated wires through preset wire pipes or wire troughs to achieve the normal operation of the electrical system. Traditional electrical wiring usually uses hard steel wires first, bends one end of the steel wire into an unsealed circle, and inserts the steel wire into the pipe. The wire is brought into the threading pipe. When the pipeline is long, two steel wires are pulled at the same time to make the ends of the steel wires hook and twist together, and then the belt line is pulled out, and then the two ends of the cloth strip are firmly tied to the belt line. The belt line is pulled back and forth manually to achieve the purpose of threading. When the pipeline is long, there are many turns and there are many threads in the pipe, one person cannot pull it, and multiple people are required to cooperate. This purely manual pulling method is time-consuming and labor-intensive, and reduces labor efficiency. The existing threading auxiliary devices are relatively complex in structure, large in size, inconvenient to use, and not suitable for ordinary construction use.
