Abstract
The utility model relates to a spanner with double heads and mouths, having four functions. The utility model is characterized in that an inner side surface of each mouth of tongs of an existing double end dead spanner is changed, wherein, the shape of an inner side surface is still a straight line, but the length is a little bit extended to contain the length of the side of two kinds of nuts and bolts in similar specifications; wherein, the shape of the other inner side surface is made to a fold line to form two short mouth of tongs in different sizes; wherein, the inner short mouth of tongs is used for nuts and bolts in a smaller size, and the outer short mouth of tongs is used for nuts and bolts in a longer size. To sum up, the utility model can adapt to the nuts and bolts in four specifications, and the utility model has the advantages that the range of applicability is wide, the portability and the utilization are convenient, and the material and the cost are saved.
Description
Technical field
The utility model relates to a kind of instrument, double end double-end wrench that especially can a four-function.
Background technology
At present, known double ended spanner can only a dual-purpose, and the scope of application is narrow, often need be equipped with a plurality ofly, carries inconvenience, seeks time-consuming.
Summary of the invention
In order to overcome the narrow deficiency of the existing double ended spanner scope of application, the utility model provides a kind of double end double-end wrench, and four-function of energy portably uses conveniently, and one is alternative two existing double ended spanners.
The technical scheme that its technical problem that solves the utility model adopts is: it is the medial surface that changes each jaw in existing double ended spanner, one of them medial surface shape still is a linearity, but length slightly lengthens, and makes it can contain the length of side of two kinds of adjacent-specification nut bolts; Wherein another medial surface shape is made polyline shaped, forms two short jaws that size is different, and wherein interior short jaw is used for than the small dimension nut bolt, and short outward jaw is used for big specification nut bolt.More than amount to nut bolt applicable to four kinds of different sizes.Because in fact there is foozle, the fork spanner impetus also only is two segment medial surfaces of diagonal position, all the other most medial surfaces are also inoperative not essential, and the utility model has only omitted the inoperative dispensable part of part, does not influence practical effect.
The beneficial effects of the utility model are, can four-functions, and applied widely, portably use conveniently, and saved material and expense.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
In the drawings, double end double-end wrench jaw medial surface, for making it, linearity can contain the length of side of two kinds of adjacent-specification nut bolts on one side, another side is a polyline shaped, the two forms two short jaws that size is different, it is 17 millimeters nut bolt that the short outward jaw of big in the present embodiment first end is used for the across flats, and it is 14 millimeters nut bolt that interior short jaw is used for the across flats; It is 10 millimeters nut bolt that the short outward jaw of microcephaly's one end is used for the across flats, and it is 8 millimeters nut bolt that interior short jaw is used for the across flats.
When need are wrenched nut bolt, with spanner as shown in FIG. direction use, insert nut bolt and pull clockwise and revolve, two opposite side of this moment, broken line one side contacted with nut bolt a bit of wherein a bit of and nut bolt together with straight line one side diagonal position mesh.Because in fact there is foozle, the fork spanner impetus also only is two segment medial surfaces of diagonal position, all the other most of medial surfaces are inoperative not essential, and the utility model has only omitted the inoperative not essential part of part, does not influence practical effect.
When need are pulled loose nut bolt, need only be with the spanner anti-face use of direction as shown in the figure, the insertion nut bolt is pulled counterclockwise and is revolved, and all the other are the same.
