Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, in particular to a special electric tool for making wire drawing and tying wires. Background Art

[0002] The geographical environment in Qinghai is complex, and most of the distribution poles are arranged in the wild. The poles are mostly in Gobi, open-ground, and swampy areas. It is common for poles to tilt, which can cause pole toppling and affect power supply reliability. Distribution workers have to spend a lot of time every year to straighten the tilted poles, and often need to use wire pulling and tying tools to fix cables and wires.

[0003] However, existing wire drawing and tying tools usually use manual or semi-automatic tools to complete the wire tying work, which is inefficient and labor-intensive. The uncertainty of manual operation leads to different tightness of the wire ties for each wire. In addition, when using a wire tying disc for wire drawing and tying, there is a lack of effective devices for fixing the wire heads. After the wire tying is completed, if the wire heads are not fixed in time, the wires are easy to loosen, resulting in poor fixing effect. The wires need to be pulled again when used for the second time.

[0004] Therefore, it is necessary to design a special electric tool for making wire tie wires to solve the above-mentioned technical problems. Summary of the invention

[0005] In response to the above-mentioned problems, the present application provides a special electric tool for wire pulling and tying, which places the pulling wire and the return wire in the notch of the cover shell, pulls the tying wire to the position to be tied, starts the power motor, and during the rotation of the internal gear unit of the adjustable damping wire feeding box, a pulling force is generated between the tying wire at the tying position and the adjustable damping wire feeding box, so that the wire threading hole and the wire lead hole are connected, and the pulling wire and the return wire are continuously tied, which greatly improves the construction efficiency, reduces the labor intensity of workers, and can also ensure that the tightening force of the wire is consistent each time, thereby improving the consistency and quality of the wire tying.
