Abstract
The utility model discloses a kind of fasteners to screw multi-functional conversion head, belongs to hardware tool.It includes the ontology of sleeve-shaped, the outer surface (1) of the ontology is made of left section of outer surface (1-1) being distributed in the axial direction and right section of outer surface (1-2), and the inner surface (2) of the ontology is made of left section of inner surface (2-1) being distributed in the axial direction and right section of inner surface (2-2)；Left section of outer surface (1-1) and right section of outer surface (1-2) are quadrangle or hexagon or hexagon or dodecagon or 12 tooth-shape structures, and left section of inner surface (2-1) and right section of inner surface (2-2) are interior quadrangle or interior hexagon or interior hexagon or interior dodecagon or interior 12 tooth-shape structure.The utility model can not only be matched with a variety of force application means, and can be screwed to the fastener of different size, shape by matched combined；It is a kind of for screwing the hardware tool of fastener.
Description
Technical field
The utility model relates to a kind of wrench sockets more particularly to a kind of for screwing the conversion element of fastener；Belong to
Hardware tool.
Background technique
Wrench socket is the specific purpose tool for screwing fastener.The inner surface of wrench socket, which is widely used, at present is usually
Interior hexagon or interior hexagon or interior 12 tooth-shape structure, outer surface use cylindrical structure.Although relatively simple for structure,
But there is also following defects.
1) matched loop bar handle can only be used to be screwed, loop bar handle, which is once lost, just cannot use；
2) nut or bolt head with outer seamed edge can only be screwed, hexagon socket head cap screw can not be screwed；
3) sleeve can only correspond to a kind of shape and (or) a kind of fastener of size, it is therefore desirable to be equipped with several sizes
The sleeve of sequence is just able to satisfy requirement, and manufacturing cost is high；
4) fastening such as it can not be inserted in the pipe fitting being mounted in pipeline, therefore the pipe fitting being mounted in pipeline cannot be screwed
Part；Function is relatively simple.
Summary of the invention
In view of the above defects of the prior art, the utility model is intended to provide a kind of fastener and screws multi-function rotating
Change head；The utility model can not only be matched with a variety of force application means, and by matched combined can to different size,
The fastener of shape is screwed.
To achieve the goals above, the utility model uses following technical scheme: it includes the ontology of sleeve-shaped, the ontology
Outer surface be made of left section of outer surface being distributed in the axial direction and right section of outer surface, the inner surface of the ontology is by along axis side
It is constituted to left section of inner surface of distribution and right section of inner surface；Left section of outer surface and right section of outer surface be quadrangle or hexagon,
Or hexagon or dodecagon or 12 tooth-shape structures, left section of inner surface and right section of inner surface are interior quadrangle or interior six
Side shape or interior hexagon or interior dodecagon or interior 12 tooth-shape structure.
There is the notch opened up in the axial direction on the barrel of ontology；Through-hole is offered on two corresponding barrels of ontology.
Compared with the prior art, the utility model is by adopting the above-described technical solution, right on the basis of conventional sleeve
Its surfaces externally and internally improves, there is an advantage in that:
1) original external cylindrical surface quadrangle or hexagon or hexagon or dodecagon or 12 teeth have been changed to
Shape etc. have seamed edge geometry, therefore only need to by way of being mutually socketed, utilize a kind of force application means (such as double offset ring spanner
Hand, back-up wrench, monkey wrench, sleeve special spanner, allen wrench, force application rod etc.) it fastener can be realized screws；
2) due to using the polygonal exterior surface with seamed edge, there is no need to allen wrenches (such as using general utility wrench
Monkey wrench) also it is able to achieve screwing for hexagon socket head cap screw；
3) due to being provided with the opening of C font on the barrel of sleeve body, the pipe being mounted in pipeline can be made
Connector is embedded in the utility model, then can carry out screwing adjusting to pipe fitting by monkey wrench；
4) multiple the utility model are mutually socketed to the effect that may also function as lengthening sleeve ontology, even if in narrow space
Occasion is also able to achieve fastener and screws.
