Description

Technical Field

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

[0002] Wire stripping pliers are a commonly used hardware tool. Their main purpose is to strip the outer skin of wires and cut wires during high-voltage construction. At present, some wire stripping pliers are provided with rollers to improve the efficiency of wire stripping. The cooperation of the rollers and the cutter heads can achieve fast wire stripping operations. For example, the utility model patent with application number 202323215168.8 (the same applicant as the present case) discloses an adjustable wire stripping pliers, which is provided with a wire stripping blade and a blade adjustment mechanism on a first pliers body, an auxiliary roller on a second pliers body, the auxiliary roller is rotatably arranged on the second pliers body, the wire stripping blade and the auxiliary roller are arranged relative to each other, and an auxiliary cavity is formed between the wire stripping blade and the auxiliary roller for stripping wires. The wire is allowed to pass through, and the blade adjustment mechanism can adjust the distance between the stripping blade and the auxiliary roller, so that when stripping the wire, the distance between the stripping blade and the auxiliary roller can be adjusted according to the wires of different diameters to ensure the stripping effect. At the same time, when assisting, the auxiliary roller guides the wire. When stripping, as the wire moves, the auxiliary roller can rotate, thereby reducing the resistance to the movement of the wire during assistance, which can reduce the difficulty of stripping, reduce the labor intensity of the operator, and achieve the purpose of labor saving. At the same time, the cutter head is arranged at the end of the threaded rod, and an adjusting nut is arranged on the first pliers body. By rotating the adjusting nut, the cutter head can be driven to telescopically move to adjust the distance between the cutter head and the auxiliary roller.

[0003] In actual production, the cutter head and the threaded rod are integrally formed, which is achieved by milling the finished screw rod into a thin sheet shape along the axial direction, and then grinding the cutting edge at the end. During processing, the threaded rod part is thicker, otherwise it is difficult to cut. The cutter head is kept sharp and needs to be processed thinner. This type of wire stripping blade is difficult to process, which seriously affects production efficiency. Utility Model Content
