Description
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 the scissors structure, and cutting edge and handle one connect two handles by pin, utilize lever principle, realize clamping, fixedly processing work or torsion, bending, the function of cutting off tinsel.Although the scissors structure is simple, laborsaving, in use, application of force stroke is larger, and cutting edge easily misplaces.
Chinese Patent Application No. 200910192242.4 multipurpose pliers comprise: disjunctor binding clip, mobile binding clip, moving sets, handle, pincers,, connecting pin, is characterized in that: between disjunctor binding clip and mobile binding clip, the employing moving sets is connected; The disjunctor binding clip is one with the pincers handle; The pincers handle is to be connected by connecting pin with handle; The part of mobile binding clip is screw rod, and nut coordinates with screw rod in mouthful position of pulling of handle.
Although Chinese Patent Application No. 200910192242.4 multipurpose pliers have adopted the binding clip of moving sets, to have overcome application of force stroke larger for part, and cutting edge is the problem of dislocation easily, and the stroke of its jaw is too little, operates constant, nor enough laborsaving.
A kind of multi-funciton hand-vice that the patent No. is 200920164404.9, comprise jaw maxilla, jaw lower jaw, hinge, upper plier handle and lower plier handle.This utility model has adopted scissors mechanism, 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 on clamp handle, gathers multi-function in integral whole.
Although the multi-funciton hand-vice function that the patent No. is 200920164404.9 is a lot, what but this hand vice still adopted is the scissors structures, in use application of force stroke is larger, scissors structure centering is poor simultaneously, pincer cutting edge easily misplaces, after the cutting edge gap increases, can shorten the service life of cutting edge.
Summary of the invention
The purpose of this invention is to provide a kind of labor-saving plier, this labor-saving plier adopts slider-crank mechanism, laborsaving, province's stroke, and it is convenient that jaw moves the large use of opening.Its two, integrate eight covers cutting edge commonly used, have multi-functionally, can simple and easyly change.
In order to achieve the above object, labor-saving plier of the present invention, comprise vice body, fixedly cutting edge, movable cutting edge, handle, fixedly 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, the moving part of vice body, connecting rod, handle, moving sets and movable cutting edge have formed 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, with movable cutting edge, is connected, and protruding guide rail is fixed guide, is fixed on vice body.
Described fixedly 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; Can there is multi-functional effect.
Concavo-convex guide rail of the present invention plays the positioning and guiding effect, and recessed guide rail is movable guiding rail, and the protruding guide rail of Length Ratio is long, and movable cutting edge is with in the guide rail sliding process, and recessed guide rail can cover protruding guide rail fully, plays dustproof, protective effect.The eight cover cutting edges that can simple and easyly change are that screw is connected with vice body, between cutting edge and vice body, the installation and positioning structure coordinated are arranged, and during use, can simple and easyly change.
Labor-saving plier of the present invention can meet multiple job requirement, laborsaving, economizes application of force stroke.
