Description

Technical Field

[0001] The utility model relates to the technical field of wire stripping tools, and more particularly to a labor-saving wire stripping pliers. Background Art

[0002] Wire strippers are one of the commonly used tools for inside electricians, motor repairers, and instrument electricians. They are used by electricians to strip the surface insulation layer of the wire head; wire strippers can separate the cut insulation of the wire from the wire and can also prevent electric shock.

[0003] To use a standard wire stripper: Find a wire stripping hole that's slightly smaller than the wire you need to strip. Place the wire you want to strip into the hole. Gently tighten the handles so the blades cut into the insulation on one side. Then, slowly slide the stripper along the length of the wire, cutting and stripping the insulation.

[0004] However, sliding the wire strippers along the insulation along the length of the wire is laborious due to frictional resistance between the insulation and the wire.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Example:

[0021] A labor-saving wire stripper, such as Figure 1-Figure 3As shown, it includes a handle 1, a pliers head 2 and a hinge part 3 arranged between the handle 1 and the pliers head 2. The outer surface of the handle 1 is provided with an insulating and anti-slip layer. After the two pliers heads 2 are fitted together, several stripping holes with different apertures are formed. The stripping holes formed are prior art and will not be described in detail here. A layer-breaking member 4 for breaking the insulation layer is fixedly provided at one end of the handle 1 near the hinge part 3. After the two layer-breaking members 4 are fitted together, several layer-breaking holes 5 with different apertures are formed, so that they can be rotated according to the diameter of the wire. The layer-breaking member 4 is fixedly connected to a layer-breaking blade 6 in the layer-breaking hole 5. The layer-breaking blade 6 is arranged along the axial direction of the layer-breaking hole 5. When the wire stripping pliers slide along the insulation layer along the length direction of the wire, the layer-breaking blade 6 will cut an opening in the insulation layer, thereby separating the insulation layer from the inner core of the wire, and the insulation layer can be directly torn off from the wire, avoiding excessive friction resistance in subsequent wire stripping operations, thereby saving effort and reducing work intensity.

[0022] like Figure 2 As shown, the symmetrically arranged layer-breaking blades 6 in the two layer-breaking parts 4 form a V-shaped angle. Through the V-shaped angle design, when the layer-breaking hole 5 is formed, the layer-breaking blades 6 can stably cut the insulating layer, and when the layer-breaking blades 6 slide along the insulating layer, a good cutting effect can be formed.

[0023] like Figure 1 and Figure 3 As shown, kneading blocks 7 are slidingly provided at the ends of the two handles 1. The kneading blocks 7 are connected to a pushing member 8 which has one end extending to the outside of the handle 1 and is used to drive the kneading blocks 7 to move. When the kneading blocks 7 clamp the wires, the pushing member 8 drives the kneading blocks 7 to move to form a kneading effect, thereby avoiding the problem that the cut insulation layer sticks to the inner core of the wire and is difficult to separate.

[0024] like Figure 3 As shown, a slide groove 11 is provided on the push member 8, and a protrusion 12 for embedding into the slide groove 11 is fixedly provided on the handle 1. The cooperation between the protrusion 12 and the slide groove 11 can prevent the push member 8 from falling off the handle 1.

[0025] At the same time, one of the handles 1 is provided with a steering gear 9 at the connection between the pushing member 8 and the kneading block 7, wherein the pushing member 8 and the kneading block 7 are all provided with a plurality of teeth at the connection between the steering gear 9, thereby realizing the engagement of the steering gear 9 with the pushing member 8 and the kneading block 7. In the other handle 1, the pushing member 8 is fixedly connected to the kneading block 7, so that the staff only needs to apply external force in the same direction to the two pushing members 8 to realize the movement of the two kneading blocks 7 in opposite directions.

[0026] An elastic member 10 is provided between the handle 1 and the kneading block 7 for fixing the normal position of the kneading block 7. The elastic member 10 prevents the kneading block 7 from sliding freely, thereby protecting the kneading block 7.

[0027] The side walls of the two kneading blocks 7 that are close to each other are provided with anti-slip lines, which increase the stability of the kneading blocks 7 when in contact with the insulating layer and improve the kneading effect.

[0028] Working principle: When stripping the wire, find the stripping hole that matches the thickness of the wire, put the wire to be stripped into the stripping hole, gently tighten the handle 1 of the wire stripper, and the blade of the pliers head 2 cuts into the insulation layer of the wire on one side, then loosen the handle 1, and then find the corresponding breaking hole 5, put the wire to be stripped into the breaking hole 5, and leave a section of space for the staff to hold at the position where the stripping hole is cut, then gently tighten the handle 1 of the wire stripper, and the breaking blade 6 on the breaking piece 4 cuts into the insulation layer of the wire. Insulation layer, then slowly slide the wire stripper along the insulation layer along the length direction of the wire to break the insulation layer, then loosen the handle 1, place the broken part of the insulation layer on the kneading block 7, and then tighten the handle 1 of the wire stripper. The two kneading blocks 7 will clamp the insulation layer, and then knock the pushing piece 8 to make the two kneading blocks 7 move in opposite directions, forming a kneading effect on the broken insulation layer, so that the insulation layer is separated from the inner core of the wire, and then it is convenient for the staff to remove the broken insulation layer.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
