Description

Technical Field

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

[0002] Wire strippers are one of the common tools used by interior electricians, motor repairmen, and instrumentation 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] How to use wire strippers: select the corresponding stripping blade according to the thickness of the cable; place the prepared cable in the middle of the blade of the stripping tool and select the length to be stripped; hold the handle of the stripping tool, clamp the cable, and slowly apply force to peel off the outer skin of the cable; loosen the tool handle and take out the cable. At this time, the metal of the cable is neatly exposed and the rest of the insulating plastic is intact.

[0004] After searching, it is known that the utility model patent type with the authorization publication number CN 218919807 U in the prior art involves a wire stripping pliers, which discloses a wire stripping pliers composed of two pliers bodies with the same appearance hinged by a pin shaft, wherein the pliers body is composed of a pliers head, a pin shaft hole and a pliers handle; a spring is arranged between the two pliers handles to facilitate the opening of the two pliers handles; a limit lock plate is arranged on the pliers handle of one pliers body to put the two pliers heads in a clamping state; a dial hole and a tool hole arranged perpendicular to the dial hole are arranged at a position of the one pliers handle close to the shaft hole, and a roller is arranged at a position corresponding to the tool hole on the inner side of the other pliers handle close to the shaft hole; a dial wheel is arranged in the dial wheel hole, and the central shaft hole of the dial wheel is threadedly connected to a wire stripping tool with a threaded rod passing through the tool hole. This patent uses a single roller and a blade of a wire stripping tool to cut cables. During the cable cutting process, the friction between the outer rubber layer of the cable and the pliers handle without a roller is relatively large. When stripping the cable, the wire strippers do not slide smoothly along the cable; when cutting the cable in a ring, the wire strippers do not rotate smoothly. Utility Model Content
