Abstract
The utility model relates to a convex wrench comprising a wrench head and a wrench handle body, wherein the working surface of wrench head is arcuate, the utility model can screw the screw bolts and screw nuts with recesses, when in use, the arc protrusion of the wrench is stuck in the recesses of the screw bolts and screw nuts, and the wrench is fixed and rotated. The wrench head of the wrench can be either movable wrench head to meet the demands of screw bolts and screw nuts with different sizes, or fixed wrench head to take down the screw nuts of a fixed size.
Description
Technical field:
The utility model relates to a kind of nut spanner, and especially a kind of working face is the spanner of convex-edge shape, belongs to hardware ﹠ tools
Technical field.
Background technology:
Nut spanner claims adjustable wrench again, is the hardware ﹠ tools of using always.Existing nut spanner, mainly by movable jaw, handle body, fixedly spanner, adjusting screw(rod) are formed, wherein fixedly spanner and handle body are usually made an integral body, and a side of movable jaw is shaped on partial screw threads, be contained in the chute of fixing spanner, be meshed with adjusting screw(rod).During use, by adjusting screw(rod) can make movable jaw fixing spanner chute in move, thereby regulate movable jaw and the fixing distance between the spanner, to adapt to the size of different nuts.The problem of this existing spanner is that when twisting common hex bolts, if bolt is too tight, often the corner angle of bolt are worn into fillet by the working face of spanner, cause the cunning of spanner and nut to twist.
The utility model content:
The purpose of this utility model is, a kind of spanner of the convex-edge shape at the bolt and nut correspondence that has groove is provided.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of spanner of convex-edge shape comprises spanner and handle body, and the working face that it is characterized in that described spanner is a convex-edge shape.
The working face of described spanner is in the inboard of spanner, and working face is an arc, can be nested on the bolt and nut that has groove and work.
Described spanner can be movable jaw, comprises fixedly a spanner and a movable jaw, can screw different bolt and nuts like this.
Described spanner can be back-up wrench, comprises the spanner that two ends are fixing, can screw the bolt and nut of correspondingly-sized so accurately.
The beneficial effects of the utility model are, use the spanner of a kind of convex-edge shape of the utility model, and the corner angle that can not produce bolt head or nut are worn into fillet, cause the dismounting situation of difficult, are easy to dismantle the bolt or the nut that have groove, and are simple and practical.
Description of drawings:
Fig. 1 is the spanner of the convex-edge shape of the utility model embodiment 1 activity.
Fig. 2 is the spanner of the fixing convex-edge shape of the utility model embodiment 2.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1, referring to Fig. 1, and a kind of convex-edge shape spanner of activity, comprise movable jaw 31, fixedly spanner 33 and handle body 32, the working face of spanner is a convex-edge shape 30, can block the bolt and nut that has groove, sliding phenomenon of twisting can not take place, and fixedly spanner 33 and handle body 32 are structure as a whole usually; One side of movable jaw 31 is shaped on partial screw threads, is contained in the chute of fixing spanner 33, can regulate the spanner size by adjusting screw(rod) 34, satisfies the needs of different size bolt and nut.
Embodiment 2, referring to Fig. 2, and a kind of fixing convex-edge shape spanner, comprise spanner 41 and handle body 40, described spanner 41 is at the two ends of handle body 40, and there is a convex-edge shape working face 411 inboard of spanner 41, the spanner 41 at handle body 40 two ends is a different size, can screw different bolt and nuts.
During use, the arc-shaped protrusions of spanner is blocked in the groove of bolt and nut, the spanner rotation gets final product.
Be not difficult to find out; the utility model is turned round reliable than the prior art folder; can slippage; it is handy to use; effectively improve maintenance efficiency of assembling, in addition to the implementation; the utility model can also have other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the protection domain of the present utility model.
