[0002] In the wiring construction of building electrical engineering, electrical conduits are usually pre-buried in the wall, and a tape is inserted into the conduit in advance to guide the wires into the conduit later. The tape is generally made of steel wire. First, one end of the steel wire is bent into an unsealed circle, and then a wire threader is used to pass the tape into the pipe, so that the cables can be installed in the electrical conduit after the main building is completed.

In the prior art, when it is necessary to guide the wire through a steel wire as a belt, one end of the wire is generally tied to one end of the steel wire, and then the steel wire is pulled from the other end of the steel wire to pull the wire into the wire tube. Since the threading end of the wire cannot be fixed, one end cannot be limited and fixed during threading and cannot be aligned with the penetration position, thereby wasting a lot of time and reducing the threading efficiency.

[0025] Working principle:

[0026] In the present application, when fixing, multiple cables are passed through multiple installation grooves 8, and the gear ring 19 is rotated, the gear ring 19 drives the transmission gear 18 to rotate, so that the worm 17 drives the worm wheel 16 to rotate, and the worm wheel 16 drives the threaded sleeve 15 to rotate, and then drives the stud 14 to drive the movable plate 12 to move, and the movable plate 12 moves to drive the limit plate 10 to move so that the limit plate 10 limits the cable, which is convenient for limiting;

[0027] In the present application, when the thickness of the cables threaded in the wire tube is different, when the limiting plate 10 drives the protective pad 9 to move and abut the cable, the toothed ring 19 is continuously rotated, so that the stud 14 continues to move, and the second spring 13 at the thicker cable is deformed, so that the movable plate 12 moves toward the limiting plate 10, and the fixed column 11 enters the limiting plate 10, and the second spring 13 is deformed until the limiting plate 10 in the installation groove 8 where the thinner cable is located limits the cable, which is suitable for limiting cables of different thicknesses, and improves the applicability of the limiting structure;

[0028] In the present application, before threading, the traction wire 5 and the traction head 4 can be passed through the wire tube 1, and then the traction head 4 is pushed so that the traction head 4 enters the traction seat 2.
