Abstract

The invention relates to a pair of practical multifunctional pliers. A rotary rod is arranged at the lower parts of plier sides of a plier body through a coupling shaft, and a hollow hexagonal socket plug-in joint is arranged at the lower end of the rotary rod; the plier body, the rotary rod and the hollow hexagonal socket plug-in joint form a rotary tool for a quick connecting with a screwdriver bit or an hexagonal socket wrench head; the screwdriver bits or the hexagonal socket wrench heads are respectively arranged in the inner sides of two plier handle sleeves, and the inner side of each plier handle sleeve is provided with a storage box for a clamp spring wire; the rotary rod can be rotated, and have three fixed working stations, such as 0 degree, 90 degrees and 180 degrees; according to the requirements, the rotary rod is moved to the 90 degrees or the 180 degrees and is locked, the hollow hexagonal socket plug-in joint in the rotary rod is connected with the corresponding screwdriver bit or the corresponding hexagonal socket wrench head, and then the pair of multifunctional pliers can be used as a screwdriver or a wrench. The pair of practical multifunctional pliers has the advantage that the clamping and twisting, the shearing and the rotary tool are integrated, so the effect of one tool with multiple functions is realized, the structure shape and strength of the traditional pliers are maintained, the convenience in use is realized, and the pair of practical multifunctional pliers is more suitable for the field of maintenance and installation.

Description

Practical multiduty pliers

Technical field

The present invention relates to a kind of hardware hand-operated tools, more particularly to a kind of practical multiduty pliers.

Background technology

In order to overcome the single defect of pliers performance, China Patent No.: 200920287730.9 give a kind of multipurpose Pliers；201320324692.6 giving a kind of pipe clamp multiduty pliers；Cn 203317377 u gives a kind of many recruitments of torch of pincers Tool.Three kinds of patented technologies are all to open up groove on the handle of traditional pliers, arrange the torch connecting by connection shaft in groove Multiple conventional small tool such as cylinder, flat file, blade, saw blade, bottle opener.The drawbacks of above-mentioned pliers one is that multiple conventional small tools are contained in In the confined space of handle, cause that unskilled labourer's lamps structure is little, low intensity, practicality is bad；Two is that some small tools are not belonged to pliers In an application category, the suitability is not strong；Three is the intensity that the putting groove opening up on pliers handle has damaged pliers handle, increases Pliers manufacture difficulty also makes the ruggedness of pliers have a greatly reduced quality；Four is to change smooth arc surface arcuate structure handle for four rib right cylinders Type structure handle, destroys application on pliers for the base of principle of human engineering, using uncomfortable and so that palm is got blisters injured； Five is that the folder that pliers script has is turned round, shearing function is not expanded.

Content of the invention

The invention aims to providing a kind of clamp handle shape do not destroyed according to base of principle of human engineering design and structure Intensity, keeps traditional clamp structure shape invariance, using comfortable, turn round, sets up on the basis of shearing function again originally having folder There is driver function, and the practical multiduty pliers of portability double-head screwdriver or double end inner hexagon spanner.

The purpose of the present invention is that by.The practical multiduty pliers of the present invention includes caliper and is socketed in two clamp handles Taper knob, the practical multiduty pliers of the present invention is characterised by: the pincers cheek bottom of described caliper is provided with an axis hole, and axis hole sets There is coupling spindle, coupling spindle passes through to rotate the hinged rotating bar of pilot hole of rod end shoulder, the lower end of rotating bar connects six in a hollow To connection-peg, in rotating bar that described caliper, caliper connect, the hollow of rotating bar bottom, connection-peg is collectively formed can for hexagonal at angle Change the driver of tool heads, the end shoulder of described rotating bar is additionally provided with three alternate 90 ° of location holes, described pincers cheek left-external side sets There is a positioning and locking screw, the right end of positioning and locking screw becomes work matching pair with three location holes rotating rod end shoulder, Described rotating bar has one in 0 °～180 ° interval round rotary motion trace on coupling spindle, and at 0 ° or 90 ° or 180 ° When become fixing locking state.

The practical multiduty pliers of the present invention, wherein said two handles are placed on inside clamp handle and are each provided with one and handle respectively Set all-in-one-piece case.

The practical multiduty pliers of the present invention, is provided with several jump ring silks, described jump ring silk bottom edge in wherein said case It is embedded in case bottom, upper end becomes smooth convergence shape semi-ring.

The practical multiduty pliers of the present invention, wherein said case pass through jump ring silk fixation deposit some different sizes or Double-head screwdriver or double end inner hexagon spanner, described double-head screwdriver or double end inner hexagon spanner and hexagonal in described hollow are to slotting Joint is inserted in pairs and is connected work matching pair.

The present invention practical multiduty pliers difference from prior art is this practical multiduty pliers under the pincers cheek of caliper A rotating bar is installed by coupling spindle by portion, and rotating bar bottom is provided with order to quick connecting screw screwdriver bit or internal hexagonal wrench head Hollow in hexagonal to connection-peg.In caliper, rotating bar and hollow, hexagonal collectively forms replaceable attachment head to connection-peg Driver.It is respectively provided with one inside two clamp handle taper knobs and can place depositing of double-threaded screw screwdriver bit or double end internal hexagonal wrench head Box, double-threaded screw screwdriver bit or double end internal hexagonal wrench head are fixed in case by the jump ring silk in case.Rotating bar Practical multiduty pliers can rotate, and there is 0 °, 90 °, 180 ° three and be locked station by fixing.As needed, move and turn , to 90 ° of positions or 180 ° of positions and after locking, in the hollow of rotating bar, hexagonal is to connecting corresponding double end on connection-peg for lever Screwdriver bit or double end internal hexagonal wrench head are so that it may conveniently and efficiently make this practical multiduty pliers as screwdriver or spanner With.The practical multiduty pliers of the present invention integrates folder torsion, shearing, driver, has the multi-functional effect of an instrument, it both kept The planform of traditional pliers and intensity, and convenient use, are more applicable for maintenance and installing area.

Below in conjunction with the accompanying drawings the practical multiduty pliers of the present invention is described further.
