Description

Practical multiduty pliers

Technical field

The present invention relates to a kind of hardware hand-operated tools, particularly relate 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 give a kind of pipe clamp multiduty pliers; CN 203317377 U gives a kind of pincers torch all-purpose instrument.Three kinds of patented technologies are all offer groove on the handle of traditional pliers, are arranged through the multiple conventional small tool such as flashlight, flat file, blade, saw blade, bottle opener that connection shaft connects in groove.The drawback one of above-mentioned pliers is that multiple conventional small tool is contained in the confined space of handle, causes that small tool structure is little, intensity is low, and practicality is bad; Two is that some small tool and pliers do not belong to an application category, and applicability is not strong; Three is the intensity that the putting groove that pliers handle is offered has damaged pliers handle, increases pliers manufacture difficulty and also makes the durability of pliers have a greatly reduced quality; Four is that to change smooth arc surface arcuate structure handle be the straight columnar structures handle of four ribs, destroys the application of base of principle of human engineering on pliers, uses uncomfortable and easily to make palm get blisters injured; Five is that the folder that pliers has originally is turned round, shearing function is not expanded.

Summary of the invention

The object of the invention is to provide and a kind ofly do not destroy clamp handle shape according to base of principle of human engineering design and structural strength, keep traditional clamp structure shape invariance, use comfortable, set up again originally having that folder is turned round, on the basis of shearing function and there is driver function, and the practical multiduty pliers of double-head screwdriver or double end inner hexagon spanner can be carried.

The object of the invention is to realize.The practical multiduty pliers of the present invention comprises caliper and is socketed in the taper knob in two clamp handles, the feature of the practical multiduty pliers of the present invention is: the pincers cheek bottom of described caliper is provided with an axis hole, axis hole is provided with coupling spindle, coupling spindle is by rotating the hinged dwang of pilot hole of rod end shoulder, the lower end of dwang to connect in a hollow hexagonal to connection-peg, described caliper, the dwang that caliper connects, in the hollow of dwang bottom, hexagonal forms the driver of replaceable attachment head jointly to connection-peg, the end shoulder of described dwang is also provided with three alternate locating holes of 90 °, described pincers cheek left-external side is provided with a positioning and locking screw, three locating holes that right end and the rotation rod end of positioning and locking screw are takeed on become work matching pair, described dwang has one 0 ° ~ 180 ° interval round rotary motion trace on coupling spindle, and become fixing locking state when 0 ° or 90 ° or 180 °.

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

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

The practical multiduty pliers of the present invention, that wherein said case fixedly deposits some different sizes by jump ring silk 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 inserted in pairs connection-peg and are connected work matching pair.

The present invention's practical multiduty pliers difference from prior art is that this practical multiduty pliers installs a dwang in the pincers cheek bottom of caliper by coupling spindle, and dwang bottom to be provided with in the hollow in order to quick connecting screw screwdriver bit or internal hexagonal wrench head hexagonal to connection-peg.In caliper, dwang and hollow, hexagonal forms the driver of replaceable attachment head jointly to connection-peg.Respectively be provided with the case that can be placed double-threaded screw screwdriver bit or double end internal hexagonal wrench head inside two clamp handle taper knobs, double-threaded screw screwdriver bit or double end internal hexagonal wrench head are fixed in case by the jump ring silk in case.Dwang can rotate on practical multiduty pliers, and has 0 °, 90 °, 180 ° three the locking stations that are fixed.As required, move dwang to 90 ° of positions or 180 ° of positions and after locking, in the hollow of dwang, hexagonal is to connection-peg connecting corresponding double-threaded screw screwdriver bit or double end internal hexagonal wrench head, just can be used as screwdriver or spanner by this practical multiduty pliers quickly and easily.Practical multiduty pliers of the present invention integrates that folder is turned round, sheared, driver, and have the multi-functional effect of an instrument, it had both maintained planform and the intensity of traditional pliers, easy to use again, was more applicable for maintenance and installing area.

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