Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a multifunctional wire stripping pliers. Background Art

[0002] Wire cutters are currently a conventional hardware tool. Although the use scenarios of wire cutters are more and more demanding, the functions of wire cutters are also more and more. For example, the utility model document with publication number CN216940203U discloses a multifunctional wire cutter, which can cut, press, pull and strip wires. However, this wire cutter still has the following technical problems: 1. The wire cutter uses conventional shears to cut wires, which is suitable for some metal steel wires. However, when cutting electrical cables and optical cables, the cut cross-section is not smooth and flat, and optical cables with uneven cross-sections cannot be used; 2. The wire cutter uses a first wire pulling groove or a second wire pulling groove for pulling wires, and the groove width of this wire pulling groove is difficult to control, that is, the force of pressing the wire harness when pulling the wire is completely controlled by the operator holding the handle sleeve, which makes pulling the wire more difficult, especially the situation where the wire clamping force is too large when pulling the wire, resulting in the wire harness being clamped and broken.

[0033] The pair of pliers heads 1 are movably hinged by a pliers head pin 3, and each pliers head 1 is provided with a wire cutting edge for cutting the steel wire. The wire cutting edges of the pair of pliers heads 1 cooperate with each other to form a wire cutting opening 4, and the pliers heads 1 are provided with a screwing groove 18 at the wire cutting opening 4 for conveniently screwing a nut. The two pliers heads 1 are also provided with a clamping half groove and a nail protecting half groove that cooperate with each other near the head, and the clamping half groove and the nail protecting half groove cooperate with each other for clamping and nail protecting.

[0034] A wire pressing protrusion 12 is provided on one of the pliers handles 2 near the pliers head pin 3, and a wire pressing groove 11 is provided on the corresponding other pliers handle 2 to cooperate with the wire pressing protrusion 12; the wire pressing protrusion 12 extends into the wire pressing groove 11 with a certain gap between the two, so that when wire pressing is required, the wire ends of two or more wire harnesses can be inserted into the wire pressing groove 11, and then the wire pressing protrusion 12 is pressed into the wire pressing groove 11 to crimp the wire ends of the wire harnesses together.

[0035] The two pliers handles 2 are also provided with a protruding plate portion 13, and the distance between the protruding plate portion 13 and the pliers head pin shaft 3 is greater than the distance between the wire pressing groove 11 and the pliers head pin shaft 3; in this way, there is enough space to set the protruding plate portion 13, thereby facilitating the subsequent setting of the wire stripping hole 14 and the cable cutting port 15.

[0036] The thickness of the protruding plate portion 13 gradually decreases from the outer pliers handle 2 toward the center. Each protruding plate portion 13 is also provided with a plurality of stripping half-grooves of different apertures and a cutting edge. The stripping half-grooves cooperate with each other to form a stripping hole 14 for convenient wire stripping. The cutting edges cooperate with each other to form a cable cutting opening 15 for convenient cutting of electrical or optical cables. The cable cutting opening 15 is generally crescent-shaped and is provided with a transversely extending transverse cutting edge on the side near the pliers head 1. The head portion mentioned in this embodiment refers only to the portion near the pliers head 1, and the transverse direction is the width of the wire cutters.

[0037] The pliers handle 2 is sheathed with a plastic handle cover 16, and the handle cover 16 is provided with an aperture mark 20 corresponding to the stripping hole 14. The aperture mark 20 can mark the wire diameter size or wire diameter number.

[0038] Each pliers head 1 is provided with a movable groove 9 for easy engagement. The movable grooves 9 of the two pliers heads 1 are interlocked and movably connected through the pliers head pin 3.

A wire clamping seam 21 is formed between the side wall of the groove bottom surface of each movable groove 9 and the groove side wall. The width of the wire clamping seam 21 gradually increases from the pliers handle 2 to the pliers head 1. Wire clamping teeth are provided on the arc surface 10 and / or on the groove side wall. Preferably, the wire clamping teeth are provided only on the arc surface 10, which simplifies the processing while being sufficient to meet the existing wire clamping requirements.

[0039] The pliers head 1 is also provided with an insertion hole 8 for convenient screw insertion, and the insertion hole 8 is located between the pliers head pin 3 and the wire pressing groove 11. The insertion hole 8 can facilitate the insertion of the screw, thereby facilitating bending or straightening.

[0040] The outer side surfaces of the pair of pliers heads 1 are provided with a toothed portion 5, and a toothed surface 6 with teeth is provided on the toothed portion 5. The width of the toothed surface 6 is smaller than the width of the pliers heads 1. The front and back surfaces of the toothed portion 5 near the short portion of the pliers handle 2 are provided with a wavy curved surface 7.
