Description
Technical field
The utility model relates to a kind of technical field of hand tools, relates in particular to a kind of labor-saving plier.
Background technology
Existing its structure of common pliers is all very simple, use also very convenient, it mainly is made up of moving caliper and fixed clamp, the center position of the connecting portion on moving caliper and fixed clamp has hinged through hole, it is hinged with moving caliper and fixed clamp that one connecting pin passes above-mentioned hinged through hole, so just formed common pliers.Because, the connecting pin of common pliers on it is the hinged through hole that passes the center position of hinge point, and moving caliper and fixed clamp is hinged, yet can relatively require great effort when using above-mentioned pliers to shear various steel wires or electric wire, sometimes need us steel wire or electric wire could be cut off with very big power, if user's strength is little, then probably can not cut off and be cut thing, therefore, brought certain inconvenience for our use, so the structure of this common pliers awaits further to improve.At original common pliers this defective of labour-saving not, in order to adapt to the needs in market, but therefore a lot of labour-saving pliers has appearred, as an application number is 01215423.7, publication number is that 2472878 Chinese utility model patent discloses a kind of instrument pincers, comprise binding clip, left socle, right support, travel(l)ing rest, gear is buckled, locking and opener, wherein at left socle, the jaw position of right support is equipped with binding clip, is provided with the hexagonal alveolus of a plurality of different sizes on binding clip, left socle, right support, travel(l)ing rest, link together in twos by the axle bolt between gear is buckled, and be provided with locking mechanism in the lower end.Above-mentioned utility model is simple in structure, and is easy to use, by a linkage is set, can make that the binding clip part of instrument pincers is constantly compacted; Thereby coupling compression joint to coaxial line, is not only saved time but also laborsaving.Though above-mentioned utility model has reached laborsaving timesaving purpose, its element that relates to is many, and structure is not very simple, and assembles also very complicated difficulty, has increased production cost virtually.Therefore, above-mentioned prior art awaits further to improve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of labor-saving plier at above-mentioned prior art present situation, and it has, and common labor-saving plier is simple in structure, easy to assembly, low cost and other advantages, can also reach time saving and energy saving purpose simultaneously.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of improved labor-saving plier, it includes moving caliper and fixed clamp, moving caliper and fixed clamp are by the operate portions that is arranged on front end, be arranged on the handle portion of rear end, and the connecting portion that operate portions and handle portion link together is formed, and on described connecting portion, have a hinged through hole, connecting pin passes described hinged through hole and moving caliper and fixed clamp is movably hinged, the center that it is characterized in that described hinged through hole is arranged on the connecting portion center line, and deflection is near the place, position of operate portions.
Above-mentioned connecting portion be shaped as the circle that diameter is 24.5mm, its position deviation connecting portion center, center of hinged through hole 4mm-5mm, the diameter of hinged through hole is 11.5mm, like this can be laborsaving, can take into account the whole firmly degree of pliers simultaneously.
Above-mentioned handle portion is provided with the waveform decorative pattern, when we put the plastic insulation sleeve pipe on handle portion, just can play better anticreep effect like this, also can play directly anti-skidding effect if be directly used in the five metals construction.
Compared with prior art, advantage of the present utility model is that its center of circle with hinged through hole is arranged on the connecting portion center line, and deflection is near the position of operate portions, pass described hinged through hole by a connecting pin again and moving caliper and fixed clamp are movably hinged, when therefore we use this labor-saving plier, certain distance because the fulcrum of pliers has moved forward, thereby increased moment, according to lever principle as can be known, we just can reach the labour-saving purpose with this labor-saving plier work the time, and, its structure is the same substantially with original common pliers, has simple in structure, easy to assembly, low cost and other advantages.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Figure 1-3, a kind of improved labor-saving plier, it includes moving caliper 1 and fixed clamp 2, the shape of moving caliper 1 and fixed clamp 2 is symmetrical, it is to be forged or cold stamping shaped forming by vanadium steel, Shot Blasting is also passed through on its surface, moving caliper 1 is by the operate portions 3 that is arranged on front end, be arranged on the handle portion 5 of rear end, and connecting portion 7 three parts that operate portions 3 and handle portion 5 link together are formed, fixed clamp 2 is by the operate portions 4 that is arranged on front end, be arranged on the handle portion 6 of rear end, and connecting portion 8 three parts that operate portions 4 and handle portion 6 link together are formed, its connecting portion 7,8 shape roughly is the circle that diameter is 24.5mm, connecting portion 7 on above-mentioned moving caliper 1 and fixed clamp 2,8 have hinged through hole, the aperture of hinged through hole is 11.5mm, and the position of these two hinged through holes is one to one, the center of above-mentioned hinged through hole is arranged on connecting portion 7, on 8 center lines, and deflection is near operate portions 3,4, connecting portion 3 is roughly departed from the center, 4 center 4mm-5mm, a connecting pin 9 passes hinged through hole 9,10 and moving caliper 1 and fixed clamp 2 are movably hinged.
We can also directly be provided with on handle portion and a series ofly make things convenient for us to hold the waveform decorative pattern of taking 10, so not only make things convenient for us to hold and take, but also can increase the attractive in appearance of whole labor-saving plier.Certainly we also can put insulating sleeve on handle portion.
