Abstract
The utility model relates to a tightening device for tightening a screw and a nut, in particular to a multi-specification sleeve for tightening a screw and a nut. The multi-specification sleeve comprises a similar-sphere body, wherein the similar-sphere body is provided with a plurality of polygonal holes. The polygonal holes with same specifications are symmetrically arranged on the similar-sphere body. The polygonal holes with different specifications are symmetrically arranged on the similar-sphere body. The polygonal holes are asymmetrically arranged on the similar-sphere body. Compared with the prior art, the tightening device has the advantages of capability of fastening multiple specifications of bolts or nuts because multiple specifications of polygonal holes are arranged on the similar-sphere body, multiple specifications of screws or nuts can be fastened, small volume, reduced cost, and convenience for carrying and using.
Description
Technical field
The utility model relates to a kind of fastened tools that is used for the fastening bolt nut, particularly a kind of many specifications sleeve that is used for the fastening bolt nut.
Background technology
Box spanner is difficult for slipping out of the hand and is used widely with easy to operate.But box spanner generally comprises the barrel bore of 2 specifications, and this just makes a box spanner to operate to the nut of 2 specific standards.In the time will tackling the operation of multiple different specifications nut, then need many cover box spanners.It is thus clear that there is following defective in existing box spanner:
The specification of the barrel bore of box spanner is few, causes range of application little, and barrel bore is prone to lose.
The utility model content
The utility model purpose is to provide a kind of many specifications sleeve, and is few with the specification that solves the barrel bore of existing box spanner in the prior art, causes range of application little, and the barrel bore technical matters that are prone to lose.
The utility model purpose realizes through following technical scheme:
A kind of many specifications sleeve comprises one type of spherosome, and said type of spherosome is provided with some polygonal hole.
Preferably, the polygonal hole of same size is symmetricly set on the said type of spherosome.
Preferably, the polygonal hole of different size is symmetricly set on the said type of spherosome.
Preferably, said polygonal hole is asymmetric is arranged on the said type of spherosome.
Preferably, said polygonal hole comprises one of them of hexagonal hole, dodecagon hole, or its combination.
Preferably, said type of spherosome surface is provided with anti-skid structure.
Preferably, said anti-skid structure comprises the rubber layer that is coated on said type of spherosome surface.
Preferably, said anti-skid structure comprises the anti-skidding line that is arranged on said type of spherosome surface, and said anti-skidding line and said type of spherosome are made into integration.
Preferably, said anti-skid structure comprises the antiskid particles that is arranged on said type of spherosome surface, and said antiskid particles and said type of spherosome are made into integration.
Preferably, said type of spherosome is hollow type of spherosome or solid type of spherosome.
Compared with prior art, the class of the utility model is provided with the polygonal hole of plurality of specifications on the spherosome, bolt or nut that can fastening more specifications, and volume is little, and cost-saved, easy to carry and use.
Description of drawings
Fig. 1 is the vertical view of the utility model;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1, many specifications sleeve of the utility model comprises one type of spherosome, and a type spherosome is provided with some polygonal hole 11,12,13,14,15,16,17.Polygonal hole can be one of them of hexagonal hole, 20 quadrilateral holes, or its combination.Certainly, also can be other polygonal hole.The polygonal hole of plurality of specifications is set on the class spherosome, and bolt or nut that can fastening more specifications use more convenient.
Fig. 2 is the structural representation of first embodiment of the utility model.In the present embodiment, be provided with on the class spherosome that shape is identical, the identical polygonal hole of size, on polygonal hole type of the being symmetricly set on spherosome of those same sizes, like polygonal hole 11,14,17 etc.Need be with bigger power fastening looser a bolt or nut in, can in the polygonal hole of symmetry, insert boosting-rod, to help fastening or looser a bolt or nut.
Second embodiment of the utility model; In the present embodiment; Variform polygonal hole is set on the class spherosome, on polygonal hole type of the being symmetricly set on spherosome of those different sizes, need be with bigger power fastening looser a bolt or nut in; Can in polygonal hole, insert boosting-rod, to help fastening or looser a bolt or nut.
The 3rd embodiment of the utility model in the present embodiment, on asymmetric ground of polygonal hole type of being arranged on spherosome, compares with symmetrically arranged situation, more polygonal hole can be set, with the bolt or the nut of fastening more specifications on the class spherosome.
In the utility model, the polygonal hole that on the class spherosome, is provided with can be a through hole, also can be the hole of not running through.
Further, for prevent rotate type spherosome with fastening looser a bolt or the process of nut in skid, can anti-skid structure be set on class spherosome surface.This anti-skid structure can be the rubber layer on type of being coated on spherosome surface, and rubber layer is set on class spherosome surface can be anti-skidding, strengthen feel, and the processing cost of this anti-skid structure is low.
This anti-skid structure also can be the anti-skidding line or the antiskid particles on type of being arranged on spherosome surface; Those anti-skidding lines or antiskid particles can be made into integration with the class spherosome; Rotating type spherosome with fastening or looser a bolt or during nut, anti-skidding line or antiskid particles can prevent that hand from skidding.This anti-skid structure is simple, and is easy to processing.Certainly, anti-skid structure also can be arranged to other anti-skidding form.
Further, a type spherosome can be set to hollow type of spherosome, also can be set to solid type of spherosome.In this example, a type spherosome is set to hollow type of spherosome, can save material like this, reduces cost.And in needs, can in symmetrically arranged polygon through hole, can insert boosting-rod, to help fastening or looser a bolt or nut.
During use, corresponding polygonal hole in the class spherosome is enclosed within on bolt or the nut, rotates a type spherosome, can be fastening or looser a bolt or nut.If when being difficult to the class spherosome rotated, can in the polygon through hole, insert boosting-rod with hand, rotate boosting-rod, a promptly rotatable class spherosome, thus fastening or looser a bolt or nut.
The utility model is provided with the polygonal hole of plurality of specifications on the class spherosome, bolt or nut that can fastening more specifications, and volume is little, and cost-saved, easy to carry and use.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
