Abstract

A pair of pliers with adjustable handle length comprises a pliers mouth, a pliers cheek and handles. The tail ends of the handles are all hinged with foldable handles, and positioning devices are arranged at the inner sides of the tail ends of the handles. In the utility model, the structure is simple, the use is convenient and the manufacturing cost is low. The handles are respectively divided into two sections by a rotating shaft, and are folded when being used at ordinary time, and when in the special condition, the foldable handles is rotated easily so as to increase the arm of force, thus achieving better effect.

Description

A kind of pliers of adjustable handle length

Technical field

The utility model belongs to the service kit field, relates in particular to a kind of pliers.

Background technology

Pliers is generally used the structural carbon steel manufacturing, and forging and pressing earlier are rolled into pincers embryo shape, through metal cuttings such as milling, polishing processing, heat-treat at last then.The handle of pincers is designed to staight shank, curved handle and 3 kinds of styles of bow handle according to the gripping form.Pincers use and contact with the energized conductor of electric wire and so on often, thus generally all be with the pillar made from insulating materials such as polyvinyl chloride on its handle, to guarantee operator's safety.

The form of jaw is a lot, common Jian Zui, Ping Zui is arranged, twitches one's mouth, patterns such as circle mouth, curved mouth, can adapt to the operation needs to the difformity workpiece.By its major function and use character, pliers can be divided into clipping pliers, cutting pliers, wire stripper, pipe vice etc.

We usually can use this instrument in maintenance process, but general a kind of pliers has only a specification, meets more unmanageable situation, often needs to increase the arm of force, thereby saving is exerted oneself or reached the inaccessiable effect of pliers originally.In maintenance process, once had the workman to utilize steel pipe socket to be located at and be used for increasing the arm of force on the handle, but make the steel pipe that just needs to be equipped with suitable diameter like this, and this thing not can find everywhere, use and be not very convenient.

The utility model content

Technical problem to be solved in the utility model provides a kind of pliers that can increase the Foldable handle of the arm of force easily.

In order to solve the problems of the technologies described above by the following technical solutions: a kind of pliers of adjustable handle length, comprise jaw, the pincers cheek and handle, the end of described handle all is hinged with folding handle, and the handle end inboard is provided with positioner.

Be provided with positioning baffle in the handle end inboard.

Described handle lateral surface is provided with groove, and the diameter of folding handle and groove match and fold time part folding handle and embed in the groove.

Described handle and folding handle all are enclosed with electro-insulating rubber outward.

The folding handle of left end is rotated counterclockwise to locating with the same straight line of left handle the time along jointed shaft; The folding handle of right-hand member goes to and locatees during with the same straight line of right handles along the jointed shaft dextrorotation.

The utility model is simple in structure, easy to use, low cost of manufacture.Utilize rotating shaft that handle is divided into two sections, use at ordinary times and fold up, special circumstances are arranged,, thereby reach better effect easily the folding handle rotating lengthening arm of force.
