Description

Technical Field

[0001] The utility model relates to the field of electrician tool pliers, in particular to a multifunctional manual wire stripping pliers with adjustable size. Background Art

[0002] Wire strippers are one of the commonly used tools for interior electricians, motor repairers, 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.

[0003] Many wire strippers on the market are also designed with multiple functions in addition to the basic functions of cutting and stripping, such as crimping, splitting, winding, twisting, etc. However, these improved wire strippers with added functions are still difficult to meet the various applications of workers in actual application scenarios. In the actual work of electricians, it is often necessary to strip and open wires of different diameters and different materials. The various wire strippers on the market currently have relatively single functions and can only strip wires of a single diameter. They do not have the function of opening wires and cannot strip and open wires of different diameters. Users need to carry multiple types of wire strippers during use, which will increase the user's load and increase the user's cost of use; different wire strippers need to be replaced during use, which will also reduce the user's work efficiency. Utility Model Content

The utility model can strip and open wires of different diameters and with different outer materials while having conventional functions of the wire stripper. At the same time, the utility model also integrates the clamping function, the nut removal function and the wire crimping function. The user can use a pair of pliers to handle different needs and complete different application scenarios. A pair of pliers can realize multiple functions and multiple uses, reduce the tools carried with the user, facilitate the user's use and improve work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a first pliers head 1, a second pliers head 2, a left pliers handle 3 and a right pliers handle 4, the first pliers head 1 and the second pliers head 2 are hinged to each other, the first pliers head 1 and the left pliers handle 3 are an integral structure, and the second pliers head 2 and the right pliers handle 4 are an integral structure; a roller mechanism 31 is arranged on the inner side of the left pliers handle 3, and a cutter mechanism 41 is arranged on the inner side of the right pliers handle 4, the positions of the roller mechanism 31 and the cutter mechanism 41 correspond to each other, and the blade of the cutter mechanism 41 corresponds to the middle position of the roller mechanism 31; the pliers heads of the first pliers head 1 and the second pliers head 2 are provided with a clamping head 11, and the lower part of the clamping head 11 is provided with an upper wire stripping hole 12.

[0007] The cutting mechanism 41 comprises a blade 411 and a blade fixing rivet pin 412 , and the blade 411 is fixed to the right pliers handle 4 via the blade fixing rivet pin 412 .

[0008] Two hexagonal wrench holes 21 are arranged on the outer side of the second clamp head 2 , and the two hexagonal wrench holes 21 are hexagonal wrench holes of different specifications.

[0009] A semicircular pressing piece 34 is disposed on the upper portion of the roller mechanism 31 , and a triangular pressing piece 35 is disposed on the lower portion of the roller mechanism 31 .

[0010] The left pliers handle 3 and the right pliers handle 4 are both covered with a rubber sheath 5. The rubber sheath 5 can facilitate the user to apply force, and can also make the user feel better and protect the user's hand skin.

[0011] The left pliers handle 3 is provided with a winding mechanism 36, and the winding mechanism 36 has a four-hole structure.

[0012] A wire breaking hole 6 is provided at the hinged overlap of the left clamp handle 3 and the right clamp handle 4. The wire breaking hole 6 can conveniently and directly cut the wire.

[0013] The outer side of the left pliers handle 3 is rotatably connected with a locking paddle 37, and the outer side of the first pliers head 1 is provided with a locking protrusion 38 adapted to the locking paddle 37. The locking can be performed by rotating the locking paddle 37, and the locking or opening of the wire stripper is controlled by the cooperation of the locking paddle 37 and the locking protrusion 38.

[0014] The upper two sides of the upper stripping hole 12 are respectively provided with cutting grooves 13 , and a blade 131 is installed in each of the two cutting grooves 13 . The blade 131 is riveted to the first clamp head 1 and the second clamp head 2 by rivets.

[0015] The working principle of the utility model: it improves the existing wire stripping pliers and adds a number of functions commonly used by staff, especially the functions of wire stripping and wire opening. When wire opening is needed, the wire only needs to be pressed into the roller mechanism 31, and the blade on the other side is pressed into the wire, and the wire can be pulled to complete the wire opening action. The whole process is easy and fast. Since the roller mechanism 31 adopts a V-shaped structure, it can work for wires of different diameters.
