Description

TECHNICAL FIELD

[0001] The utility model relates to a pair of pliers, in particular to a pair of pliers with special handles, and belongs to the technical field of pliers. BACKGROUND

[0002] Pliers are a kind of hand tools used for clamping, fixing workpieces or twisting, bending and cutting metal wires. The shape of pliers is V-shaped, generally comprising a handle, a jaw and a mouth. Pliers are usually made of carbon structural steel, which is forged and rolled into a blank shape, then subjected to metal cutting processes such as milling and polishing, and finally heat treated.

[0003] Chinese patent No. CN211136837U provides a pair of pliers, comprising a first plier body and a second plier body. The first plier body includes a first plier head, a first plier jaw, a first plier neck and a first plier handle. The second plier body includes a second plier head, a second plier jaw, a second plier neck and a second plier handle. The first plier head and the second plier head are oppositely arranged at the head of the pliers. The first plier jaw and the second plier jaw are hinged. The first plier jaw is between the first plier head and the first plier neck. The second plier jaw is between the second plier head and the second plier neck. The first plier neck and the second plier neck are oppositely arranged. The first plier handle and the second plier handle are oppositely arranged at the tail of the pliers. A wire stripping part one is provided on the first plier head. A wire stripping part two is provided on the second plier head. The wire stripping part one and the wire stripping part two form a non-circular blade wire stripping part. A pressing part is also provided on the pliers.

[0004] However, the above-mentioned case improves the wire stripping effect and is beneficial to popularization and application, but cannot solve or does not have the limiting function. When stripping the wire, it is usually only relied on the worker's feeling to control the clamping degree. If the clamping degree of the two plier heads is too large, the opening of the two plier heads will be too small, which may easily damage the wire core inside the wire. If the clamping degree of the two plier heads is too small, the opening of the two plier heads will be too large, which makes it difficult to break the wire skin.

[0005] Therefore, the utility model is proposed. UTILITY MODEL CONTENT

[0026] As a technical optimization scheme of the utility model, the handle front section 101 and the handle rear section 102 are provided with the adjusting assembly 500, the extension block 502 is fixedly arranged at one end of the handle rear section 102, and the extension block 502 is slidably inserted in the inside of the sliding cavity 501, the fixing box 503 is fixedly arranged on the outer wall of the handle front section 101, the inside of the fixing box 503 is slidably connected with the insertion block 504, the outer wall of the insertion block 504 is provided with the extension to the push block 506, the inside of the extension block 502 is provided with the insertion slot 505, and the insertion block 504 penetrates the insertion slot 505, the inner wall of the fixing box 503 is provided with the spring 507 connected with the insertion block 504, and the adjusting assembly 500 is used for adjusting the total length of the handle front section 101 and the handle rear section 102, so that the pliers can be used for different sizes of hands.

[0027] In use, the two handle assemblies 100 are opened so that the two clamp heads 401 are open to the point where they can clamp the outer sheath of the wire without damaging the wire core. The limiting blocks 201 slide inside the through slots 202, causing them to abut against each other. Rotating the clamping screw 212 moves the upper clamping plate 203 downwards. As the upper clamping plate 203 moves downwards, it causes the clamping block 208 to press against the rotating block 210, causing the rotating block 210 to rotate. The end of the rotating block 210 away from the clamping block 208 pushes the lower clamping plate 204 upwards. The upper and lower clamping plates 203 and 204 clamp and fix the limiting blocks 201. When in use, the rear sections 102 of the two handles are gripped tightly, at which point the two clamp heads 401 are widest open. The opening is just right to cut the outer sheath of the wire without damaging the wire core, thus avoiding the problem of easily damaging the wire core by relying on the worker's sense of touch to cut the outer sheath. When different pliers heads 401 need to be replaced according to different usage needs, the fixing screw 404 is threaded out from the inside of the fixing hole 405. When adjusting the total length of the component away from the fixing block 402, the rear section 102 of the handle is moved so that the extension block 502 slides inside the sliding cavity 501. After adjusting to the required length, the push block 506 is released. The elastic force of the spring 507 can push the plug 504 to be inserted into the slot 505. The total length of the front section 101 and the rear section 102 of the handle can be adjusted, making it suitable for different hand sizes and achieving flexible adjustment function.
