Abstract
The utility model discloses a multiformat wrench, relating to a manual hardware tool, in particular to a technical field of opening wrench. The multiformat wrench comprises a wrench body and a wrench head; the two working faces of the opening of the wrench head are respectively provided with a wrench working face made of a plurality of surfaces, or a working face is provided with a wrench working face made of a plurality of surfaces and the other is a rectilineal face. The utility model changes the working mode that the bolt cusps of the primary bolts are inside the two opposite rectilineal faces to the working model that the two opposite rectilineal faces form a trilinear contacted with the bolt, making the cusps of the bolt not contact with the wrench port working faces and avoiding the abrasion of the bolt cusps; the working face made of a plurality of surfaces increases the specification of the wrenches, and makes a wrench port can operate bolts in two specifications; the surface of the corresponding working face combined with the surfaces can be back in the estate that the blots are not detached. The utility model is convenient to use, has high work efficiency, and does not break the bolts.
Description
Technical field
The utility model relates to manual hardware ﹠ tools, relates in particular to a kind of open-end wrench technical field.
Background technology
One of present employed open-end wrench is pulled mouth only can corresponding specification, in the occasion of using the plurality of specifications bolt, then just must carry the spanner of plurality of specifications, simultaneously, because spanner is pulled oral-lateral face and bolt point angular contact when work, make bolt be easy to damage, make the bolt corner wear, the bolt after the wearing and tearing can not normally use.
Technical scheme
At above defective, it is a kind of easy to use that the utility model provides, and high efficiency is not damaged many specifications spanner of bolt.
The utility model comprises pulls body, driving end, is respectively equipped with the spanner working face of being made up of a plurality of curved surfaces on two working faces of driving end opening; Or one of them working face is provided with the spanner working face that a plurality of curved surfaces are formed, and another working face is for facing directly.
The wedge angle that the utility model has changed original bolt all is in the interior working method of two corresponding straight flanges, but forms three-way the contact with bolt, makes the wedge angle of bolt not contact with plate mouth working face, has avoided the bolt point corner wear; The working face that a plurality of curved surfaces form has increased the specification of spanner, makes a plate mouth can operate the bolt of two specifications; The curved surface of corresponding working face in conjunction with above-mentioned curved surface, makes spanner when work, can be under the state that does not break away from bolt return.The utility model is easy to use, and high efficiency is not damaged bolt.

The specific embodiment
The utility model is established many curved surfaces on two working faces 1,2, the curved surface 3 oral area openings that are provided with on the working face of a plate mouth 2 therein are big, and bottom opening is little, forms step-likely, constitutes the embedded location of corresponding two kinds of specification bolts with another working face.Make a double (end) wrench can realize the job requirement of four specifications.
On working face 1, corresponding above-mentioned curved surface 3 is established curved surface 4, and this curved surface 4 is more shallow, is the convenient wrench return.
Operation principle of the present utility model is: wrench opening is designed to the open surfaces be made up of some curved surfaces, the bolt of the corresponding different size of energy, during each working surface work, contact with bolt with contact point 7 by contact point 5, contact point 6 and to carry out work, wherein contact point 5, contact point 6 and contact point 7 have left the cusp at bolt angle, then easy damaged bolt angle not; The bolt that fillet has been damaged at the bolt angle also can use simultaneously.
In addition, this structure also makes the spanner can be to the active force reversed turning under the prerequisite of not leaving bolt, and bolt is motionless, and this kind structure can not worked under spanner does not break away from the situation of bolt like this, has the function of ratchet spanner, has improved operating efficiency.
Working face 1 can also be set to straight flange 8, can adapt to two kinds of different size bolts.
Claims (1)
1, a kind of many specifications spanner comprises and pulls body, driving end, it is characterized in that, is respectively equipped with the spanner working face of being made up of a plurality of curved surfaces on two working faces of driving end opening; Or one of them working face is provided with the spanner working face that a plurality of curved surfaces are formed, and another working face is for facing directly.
