[0002] The wire threader is an indispensable wiring tool for electricians in buildings. At present, the wire threaders available on the market are composed of a steel wire rope and a smooth steel head connected to both ends of the steel wire rope. With the development of my country's economic construction, my country's construction industry has developed rapidly, and traditional wire threaders can no longer meet the needs of this development. During construction or line modification, there are often places where the pipeline has an arc or a bend. The wire threader cannot manually control the direction of the threading head, so it cannot pass through. The pipe can only be disassembled at the turning point and threaded twice. This construction operation wastes manpower and material resources, is cumbersome to operate, and greatly reduces construction efficiency. How to provide a wire threader that can control the direction of the threading head to make left or right bends and better pass through complex pipeline environments has become an imminent problem.

[0011] The beneficial effects of the utility model are:
[0012] The utility model provides a threader with a direction changeable, which can be used when encountering a curved or curved pipeline. By pulling the traction line, the movable connecting rod in the middle part of the guide groove is subjected to the tension of the threading head and the annular iron hoop, causing the rod to bend. The traction line changes the shape of the guide groove to cause the threading head 2 on the upper part of the steel wire to generate tension, so that the threading head can turn, thus solving the problem that the original threader cannot pass through the curved or curved pipeline, and can manually control the direction of the threading head, bend left or right, so that it can better pass through complex pipeline environments. The guide groove is made of hard material, which has a certain ability to resist deformation and is durable. The device has a simple structure and is easy to operate, thus saving manpower and material resources and improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Reference Figure 1A threader with changeable direction, comprising a threader body, a fixing, a guide groove and a traction line 8, the threader body comprising a steel wire 1 and a threading head 2, a threading head 2 is arranged on the upper part of the steel wire 1, a fixing is arranged on the steel wire 1, the fixing comprises a first fixing member 3 and a second fixing member 4, the guide groove comprises a first guide groove 6 and a second guide groove 5, one end of the guide groove is fixedly connected to the threading head 2, the other ends of the first guide groove 6 and the second guide groove 5 are respectively fixedly connected to the first fixing member 3 and the second fixing member 4, the middle part of the guide groove is a movable connecting rod 7, the guide grooves are provided with traction lines 8, and the traction lines 8 can move in the guide grooves and the fixings. By setting a fixing part on the steel wire 1, one end of the traction line 8 is fixed at the connection between the threading head 2 and the steel wire 1, and part of the traction line 8 is placed in the left and right guide grooves. The position of the traction line 8 is fixed by the fixing part. If there is a bend or an arc, and the threader needs to bend left or right, the direction of the threading head 2 can be controlled by pulling the traction line 8 on the left or the traction line 8 on the right, so that the threader can pass through the pipeline environment with a bend or an arc.
[0019] The fixing part is an annular iron hoop. The guide groove is made of hard material, which has a certain ability to resist deformation and is durable. The distance between the first fixing part 3 and the connection between the steel wire 1 and the threading head 2 is 300 mm. The distance between the second fixing part 4 and the connection between the steel wire 1 and the threading head 2 is 350 mm. The threading head 2 is a smooth steel head, and the diameter of the threading head 2 is consistent with the diameter of the steel wire 1.
[0020] The working principle of the utility model is as follows: a fixing is set at 300mm and 350mm from the connection between the threading head 2 and the steel wire 1, one end of the traction line 8 is fixed at the connection between the threading head 2 and the steel wire 1, one end of the guide groove is fixedly connected to the connection between the threading head 2 and the steel wire 1, and the other end is fixedly connected to the fixing, and the control line of the traction line 8 is put into the left guide groove and the right guide groove, and the position of the traction line 8 is fixed by the fixing. When the operator is in use, the threader is put into the pipeline. When encountering a pipeline that needs to change the direction of the threader, if you want to control the threading head 2 to bend to the left, pull the traction line 8 on the left side, and the movable connecting rod 7 is subjected to the tension of the threading head 2 and the annular iron hoop, and bends. The traction line 8 generates a pulling force to the left of the threading head 2 through the shape of the guide groove, so that it turns left. When the threader needs to bend to the right, pull the traction line 8 on the right side, and the threading head 2 generates a pulling force to the right, so that it turns right. If the threader needs to be restored to a vertical state, just release the traction line 8. When not in use, the movable connecting rod 7 is straightened and is in a parallel state with the threader, so as to be integrated.
[0021] The utility model provides a threader with a direction changeable, which can be used when encountering a curved or curved pipeline. By pulling the traction line 8, the movable connecting rod 7 in the middle part of the guide groove is subjected to the tension of the threading head 2 and the annular iron hoop, causing the rod to bend. The traction line 8 changes the shape of the guide groove to cause the threading head 2 on the upper part of the steel wire 1 to generate tension, so that the threading head 2 can turn, thus solving the problem that the original threader cannot pass through the curved or curved pipeline, and can manually control the direction of the threading head 2, left or right, so that it can better pass through the complex pipeline environment. The guide groove is made of hard material, which has a certain ability to resist deformation and is durable. The device has a simple structure and is easy to operate, thus saving manpower and material resources and improving construction efficiency.

Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
