Description

Labor-saving plier
Technical field
The present invention relates to a kind of hand vice in hardware & tools, particularly relate to a kind of labor-saving plier.
Background technology
Existing hand vice mostly are scissors structure, and cutting edge and handle one, connect two handles by pin, utilize lever principle, realize clamping, fixing processing work or torsion, bend, cut off the function of tinsel.Although scissors structure is simple, laborsaving, in use, forcing stroke is comparatively large, and cutting edge easily misplaces.
Chinese Patent Application No. 200910192242.4 multipurpose plier, comprising: disjunctor binding clip, mobile binding clip, moving sets, handle, pincers handle, connecting pin, is characterized in that: adopt moving sets to be connected between disjunctor binding clip with mobile binding clip; Disjunctor binding clip and pincers are being one; Pincers handle is be connected by connecting pin with handle; The part of mobile binding clip is screw rod, and nut coordinates with screw rod in a mouthful position of pulling for handle.
Although Chinese Patent Application No. 200910192242.4 multipurpose plier have employed the binding clip of moving sets, it is comparatively large that part overcomes forcing stroke, the problem that cutting edge easily misplaces, and the stroke of its jaw is too little, operates constant, nor enough laborsaving.
The patent No. is a kind of multi-funciton hand-vice of 200920164404.9, comprises jaw maxilla, jaw lower jaw, hinge, upper plier handle and lower plier handle.This utility model have employed scissors mechanism, clamp handle is provided with turret head bayonet socket, octagonal head bayonet socket, cruciform screw driver head, in-line crewdriver attachment, chopping sword and internal hexagonal wrench head, gathers multi-function in integral whole.
Although the patent No. be 200920164404.9 multi-funciton hand-vice function a lot, but what this hand vice still adopted is scissors structures, in use forcing stroke is larger, scissors structure centering is poor simultaneously, pincer cutting edge easily misplaces, cutting edge radius can shorten the service life of cutting edge after increasing.
Summary of the invention
The object of this invention is to provide a kind of labor-saving plier, this labor-saving plier adopts slider-crank mechanism, and laborsaving, province's stroke, it is easy to use greatly that jaw moves opening.Its two, integrate the conventional cutting edge of eight covers, have multi-functional, can simple and easyly change.
In order to achieve the above object, labor-saving plier of the present invention, comprise vice body, fixing cutting edge, movable cutting edge, handle, fixing cutting edge, movable cutting edge are that moving sets connects, and it is characterized in that: also comprise connecting rod, movable cutting edge is connected with connecting rod by the moving part of moving sets, moving part and the movable cutting edge of vice body, connecting rod, handle, moving sets constitute slider-crank mechanism, and movable cutting edge can slide, and handle is the point of application of mechanism.
Described moving sets is concavo-convex guide rail structure, positioning and guiding, and centering is good, and recessed guide rail is movable guiding rail, is connected with movable cutting edge, and convex guide rail is fixed guide, is fixed on vice body.
Described fixing cutting edge, movable cutting edge and vice body, for being flexibly connected, are furnished with the cutting edge that eight covers can simple and easyly change, and are respectively comprehensive sword, flat mouth sword, nock sword, edge of a knife sword, sharp mouth sword, arc line ball sword, square line ball sword, wire stripping edge; Multifunctional effect can be had.
Concavo-convex guide rail of the present invention plays positioning and guiding effect, and recessed guide rail is movable guiding rail, and length is longer than convex guide rail, and movable cutting edge is with in slide process, and recessed guide rail can cover convex guide rail completely, plays dust-proof, protective effect.Eight to overlap the cutting edge that can simple and easyly change be that screw is connected with vice body, has the installation and positioning structure coordinated, during use, can simple and easyly change between cutting edge with vice body.
Labor-saving plier of the present invention can meet multiple job requirement, laborsaving, economizes forcing stroke.
