Description
Technical field
The utility model relates to hardware ﹠ tools, particularly a kind of monkey wrench.
Background technology
Monkey wrench is widely used hardware ﹠ tools, common monkey wrench is two parallel planes with the plane of action of nut, the weak point of this monkey wrench is that the field of conjugate action with nut has only two faces, can be easy to skid and wear and tear because of the torsion that bears is excessive, even nut can be stung badly, make monkey wrench and the split loading nut performance of all losing the job.
Summary of the invention
In order to overcome the shortcoming of prior art, goal of the invention of the present utility model is: a kind of monkey wrench is provided, can form four fields of conjugate action between this monkey wrench and the nut, area of contact is big, can bear bigger torsion, can not cause skidding and wear and tear between the field of conjugate action, can make monkey wrench and demolished nut can both keep good working performance.
The purpose of this utility model is achieved in that a kind of monkey wrench, comprise handle body, movable jaw, the front end of described handle body is provided with the fixedly spanner with hexagonal hole, the front portion of described handle body is provided with cavity volume, the middle part of described handle body is provided with groove and groove, and described groove connects by cavity volume and hexagonal hole, and the middle part bilateral symmetry of described groove is provided with the guide block of projection, the both sides, rear end of described groove are provided with dop, and the handle body center at described groove rear portion is provided with back-up block; Described movable jaw is the shovel shape, front end is provided with V-notch, the V-arrangement angle of this V-notch is 120 degree, the both sides, middle part of described movable jaw are provided with slideway, this slideway front end is provided with and the identical breach of described guide block shape, the afterbody of described movable jaw is a screw rod, and the middle part of described movable jaw also is provided with screw and wears groove; Described movable jaw is movably arranged in the described groove, ccontaining proficiency wheel nut in the described groove, and described hand wheel nut and described screw rod are spirally connected, and described hand wheel nut tail end and described back-up block are movable pegs graft; Described monkey wrench also comprises a cover plate, and this cover plate is fastened on described movable jaw top and fixedly mounts by screw and handle body.
On the described fixedly spanner opening is arranged.
Described back-up block is the inverted cone shape back-up block.
The beneficial effect that the utility model produces is: can form four fields of conjugate action between the utility model and the nut; area of contact doubles; stressed more even; fit is stable, can bear bigger torsion, sliding dental phenomenon can not occur; can effectively protect nut; can make monkey wrench and nut can both keep good working performance, and make things convenient for the user to operate, light, laborsaving.
The utility model is described in further detail below in conjunction with drawings and Examples.
