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 scissors structures, in use application of force stroke is larger, scissors structure centering is poor simultaneously, pincer cutting edge easily misplaces, after cutting edge gap increases, can shorten the service life of cutting edge.
Summary of the invention
The purpose of this utility model is to provide a kind of labor-saving plier, and this labor-saving plier adopts slider-crank mechanism, laborsaving, province's stroke, and it is easy to use greatly that jaw moves opening.Its two, integrate the conventional cutting edge of eight covers, have multi-functionally, can simple and easyly change.
In order to achieve the above object, labor-saving plier of the present utility model, 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, is connected with movable cutting edge, and protruding guide rail is fixed guide, is fixed on vice body.
Described fixedly cutting edge, movable cutting edge for being flexibly connected, are furnished with the cutting edge that eight covers can simple and easyly change with vice body, 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 utility model plays 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 guide rail sliding process, and recessed guide rail can cover protruding guide rail completely, 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, have the installation and positioning structure coordinating, and during use, can simple and easyly change.
Labor-saving plier of the present utility model can meet multiple job requirement, laborsaving, economizes application of force stroke.
