Background Art

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.

Most of the current wire strippers are used for the surface insulation layer of the wire head. If it is necessary to strip the insulation layer in the middle of the wire, it is necessary to use the wire strippers to open two disconnection points in the insulation layer in the middle of the wire to disconnect it from the overall insulation layer for stripping. If it is necessary to strip the insulation layer of the corresponding length, it is also necessary to measure the positions of the two disconnection points, which is very troublesome. Therefore, an adjustable wire stripper is needed to solve the above problem.

The upper parts of the first handle 1 and the second handle 2 are rotatably connected by a rotating shaft 6. The first handle 1 and the second handle 2 are sleeved with rubber sleeves. The rubber sleeves on the first handle 1 and the second handle 2 can increase the friction and comfort of the user's grip; the positioning plate 3 is fixedly mounted on the upper end of the second handle 2, and a semicircular positioning groove 301 is provided from left to right on the front side of the positioning plate 3. There are a plurality of semicircular positioning grooves 301, and a plurality of semicircular positioning grooves 301 are provided. The positioning grooves 301 are evenly arranged on the front side of the positioning plate 3 from top to bottom, and the diameters of the several semicircular positioning grooves 301 increase from top to bottom. Through the several semicircular positioning grooves 301 with different diameters, it is convenient to clamp wires of different diameters; the adjusting frame 4 is fixedly installed on the upper end of the first handle 1, and a fixed blade 401 is fixedly installed on the rear side of the left end of the adjusting frame 4. The rear end of the fixed blade 401 can contact the front side of the positioning plate 3, and a threaded shaft 402 is rotatably installed at the inner center of the adjusting frame 4 from left to right. A limit plate 404 and a measuring plate 403 are fixedly installed inside the adjusting frame 4 from left to right, and the measuring plate 403 and the limit plate 4 04 are respectively located at the upper and lower sides of the threaded shaft 402, and a ruler is drawn on the front side of the measuring plate 403.
