[0002] Wire lugs are often used for cable end connection and splicing. They can make the connection between cables and cables, cables and electrical appliances more secure and safer. They are commonly used materials for construction, power equipment, electrical appliance connections, etc. The insulation layer at the end of the soft cable is generally cut and stripped by hand with a handheld knife. After the insulation layer is stripped, the end wire without the insulation layer will loosen and expand outward, and the wire cross-section is not round, and the wire head is tilted. The wire at the end of the cable is forked. When the wire lug is put on, only part of the wire enters the wire lug. Even if the wire is straightened and re-put on the wire lug many times, a small number of wire forks cannot enter the wire lug. The wire outside the wire lug can only be clamped off; clamping off part of the wire at the end of the cable will reduce the cross-sectional area of the cable end and reduce the current carrying capacity of the cable; and it will increase the cavity in the cable lug, so that the wire lug and the cable are not squeezed tightly and the contact is not tight. The cable end is easy to heat up or even burn out, causing electrical accidents. Utility Model Content

[0019] The utility model is described in conjunction with the accompanying drawings.
[0020] like Figure 1-Figure 4As shown, an auxiliary device for cable installation nose comprises an annular tightening belt 1 and a tightening component arranged at one end thereof; the other end of the annular tightening belt 1 is arranged in the tightening component; the annular tightening belt 1 as a whole is an annular belt with two ends open, and the middle position of the annular belt is provided with equally spaced card slots 2; an annular positioning groove 3 is provided below each card slot 2 on the annular tightening belt 1; the tightening component comprises a tightener 4, and a rotating handle 5 is fixedly connected to the rear end of the tightener 4.
[0021] The tightener 4 is a horizontal columnar structure as a whole, and a horizontal rotating shaft 6 is arranged inside the tightener 4; the rotating shaft 6 runs through the tightener 4, and the rotating shaft 6 is connected to spiral pieces 7 arranged equidistantly outside the axial diameter of the inner part of the tightener 4; the spiral pieces 7 are meshed and connected with the slot 2, and the slot 2 can move with the rotation of the spiral pieces 7; here, the rotating handle 5 drives the rotating shaft 6 to rotate, and then drives the spiral piece 7 to rotate, so that the slot 2 meshed with it can be moved, so that the annular tightening belt 1 can be tightened or Relax, thereby stirruping the wire core 13 of the cable 12; the rotating handle 5 is a rectangular structure as a whole, and its interior is a cavity structure, and a cutting knife 8 is inserted in its cavity; the cutting knife 8 includes a knife body 9; the front end of the knife body 9 is connected to a knife head 10 by a thread; the knife head 10 is threadedly connected to facilitate the replacement of different types of knife heads 10 to adapt to different types of cables 12. When the insulation layer 14 of the cable 12 is thicker, a longer knife head 10 can be selected. When the insulation layer 14 of the cable 12 is thinner, A blade head 10 of a shorter length can be selected to cut the insulation layer 14 of the cable 12 without easily cutting the cable core 13, thereby achieving a multi-purpose purpose; the volume of the blade body 9 is smaller than that of the rotating handle 5, and the blade body 9 can be partially inserted into the cavity of the rotating handle 5; a pull ring 11 is also fixedly connected to the rear end of the blade body 9; the blade body 9 can be conveniently inserted into the rotating handle 5, reducing the volume of the entire tool, making it convenient to carry, and the pull ring 11 can be conveniently used to take the blade body 9, which is convenient to use; the positioning groove 3 is hollow The structure has a groove length parallel to the long side of the annular tightening band 1; the positioning groove 3 here is used to locate the position and neatness of the cutting cut of the cable 12. After the annular tightening band 1 is tightened on the outside of the insulating layer 14 of the cable 12 to be cut, the cutting knife 8 is taken out, and the knife head 10 is inserted into the positioning groove 3 and annular cutting is performed along the positioning groove 3.
