Description

Technical Field

[0001] The utility model relates to the technical field of pliers, in particular to a labor-saving wire stripping pliers. Background Art

[0002] Pliers are commonly used hardware tools that can perform operations such as cutting and stripping wires. However, the wire stripping solutions of the wire strippers currently on the market are mostly to set a wire hole on the pliers head and then set a blade in the wire hole. When in use, the wire is passed through the wire hole, and the blade strips the wire by pulling the wire. For example, the utility model patent with authorization announcement number CN218678241U discloses a wire stripper that strips wires by setting a wire splitter and a copper ring. When using this wire stripper, the wire needs to be pulled vigorously to achieve stripping, which is inconvenient to use.

[0003] Later, some wire strippers that save more effort appeared, such as the utility model patent with application number 202323215168.8 (the same applicant as the present case), which involves an adjustable wire stripper. A cutting blade is arranged on the first pliers body, a cutting and stripping roller is arranged on the second pliers body, and the cutting and stripping roller is rotatably arranged on the second pliers body. A power line is passed between the cutting and stripping roller and the cutting blade. When stripping the wire, the cutting and stripping roller guides the wire, reduces the resistance to the movement of the wire during stripping, reduces the difficulty of stripping, reduces the labor intensity of the operator, and achieves the purpose of saving effort.

[0004] Although this arrangement can reduce the resistance to wire movement during wire stripping to a certain extent, only a portion of the wire can contact the cutting and stripping roller, and the remaining wire still has a certain resistance when it moves relative to the pliers body, thereby limiting the labor-saving effect.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a labor-saving wire stripping pliers, which can realize fast stripping and cutting of wires, and can save labor in operation during use, thereby improving the wire stripping efficiency.

[0026] like Figure 1-Figure 4As shown, the labor-saving wire stripping pliers include a first pliers body 1 and a second pliers body 2 connected by a hinge shaft, a cutting blade 3 and a first cutting and stripping roller 4 are arranged on the first pliers body 1, and a second cutting and stripping roller 5 is arranged on the second pliers body 2, the first cutting and stripping roller 4 is rotatably arranged on the first pliers body 1, and the second cutting and stripping roller 5 is rotatably arranged on the second pliers body 2, and a stripping portion 6 for the wire to pass through is formed between the first cutting and stripping roller 4 and the second cutting and stripping roller 5, and the end of the cutting blade 3 is located in the stripping portion 6. In actual operation, the user only needs to place the wire in the stripping portion 6, and then close the first pliers body 1 and the second pliers body 2, so that the first cutting and stripping roller 4 and the second cutting and stripping roller 5 clamp the wire. At this time, the wire and the wire stripping pliers are relatively moved, and the end of the cutting blade 3 will strip the wire, and the first cutting and stripping roller 4 and the second cutting and stripping roller 5 play a guiding role for the wire, so that the wire stripping operation can be performed without effort, and the wire can be stripped quickly and labor-savingly.

[0027] like Figure 3 As shown, an avoidance groove 41 is provided on the first cutting and stripping roller 4, and the cutting blade 3 is arranged through the avoidance groove 41 to ensure that the end of the cutting blade 3 can be accurately located in the stripping portion 6, thereby achieving accurate cutting of the wire and avoiding interference of the first cutting and stripping roller 4 with the cutting blade 3.

[0028] In some embodiments, Figure 2 As shown, a first mounting groove 11 is provided on the first pliers body 1, first clamping grooves 12 are provided on both sides of the first mounting groove 11, first rotating shafts 42 are provided on both ends of the first cutting and stripping roller 4, and the first rotating shaft 42 is rotatably provided in the first clamping groove 12, so that the first cutting and stripping roller 4 can stably and flexibly rotate on the first pliers body 1. Similarly, a second mounting groove 21 is provided on the second pliers body 2, second clamping grooves 22 are provided on both sides of the second mounting groove 21, and second rotating shafts 51 are provided on both ends of the second cutting and stripping roller 5, and the second rotating shaft 51 is rotatably provided in the second clamping groove 22, so that the second cutting and stripping roller 5 can stably and flexibly rotate on the second pliers body 2.
