Abstract
The invention discloses a wrench which comprises a wrench body. The wrench body is of a stereo structure with two arc-shaped ends. The two ends of the wrench body are each provided with clamping openings. The number of the clamping openings is four, and the two ends are each provided with two clamping openings. The clamping openings are of a closed regular hexagon structure, and inner angles are all 120 degrees. The four clamping openings are different in specification and type, the two clamping openings in any end comprise the large clamping opening and the small clamping opening in a combined and matched manner, and the clamping openings are the same in depth. In this manner, the wrench is simple in structure and reasonable in design; by means of the characteristic that the large clamping openings and the small clamping openings do not inference with one another, the four regular-hexagon clamping openings different in type are formed in the two ends of the wrench, the function is comprehensive, and high practicality is achieved; and the wrench can be matched with bolt or nut assemblies of multiple types and has certain economic benefits and market prospects.
Description
Technical field
The present invention relates to the fastener field of dismounting nut, particularly relate to a kind of spanner.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is shaped with opening or the trepanning of grip bolt or nut usually in the one or both ends of shank, during use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.Spanner can be divided into monkey wrench and solid wrench two kinds, and the opening size of monkey wrench is adjustable, can adapt to the nut dismounting of sizes; Solid wrench opening size is fixed, and usually needs to adopt the complete use of the spanner of multiple different size, and double offset ring spanner is exactly wherein a kind of, and in the market, a bayonet socket spanner only being arranged one or both specifications too wastes resource.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of spanner, possesses plurality of specifications and carries out choice for use.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of spanner, it is characterized in that, comprise: wrench body, the stereochemical structure of described wrench body to be two ends be arc-shaped, described wrench body two ends are provided with bayonet socket, described bayonet socket has 4, two ends respectively arrange two, and described bayonet socket is closed regular hexagon structure, and interior angle is 120 °, wherein, the specifications and models of four bayonet sockets are all different, and two bayonet sockets of any one end are a large bayonet socket and a little bayonet socket combination collocation, and the degree of depth of each bayonet socket is identical.
In a preferred embodiment of the present invention, the making material of described wrench body is chrome-vanadium steel.
In a preferred embodiment of the present invention, the specification of described bayonet socket can be 7,10,12,14,17,19,22,24.
In a preferred embodiment of the present invention, the thickness of described wrench body is 2cm.
In a preferred embodiment of the present invention, the degree of depth of described bayonet socket is the half of described wrench body thickness, is 1cm.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, adopt the non-interfering feature of size bayonet socket, the regular hexagon bayonet socket of four different models is set at spanner two ends, complete function, practical, bolt or the nut assembly of Multiple Type can be mated, have certain economic benefit and market prospects.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Fig. 2 is the front view of shown spanner;
Fig. 3 is the dorsal view of shown spanner;
In accompanying drawing, the mark of each parts is as follows: 1-wrench body, 2-bayonet socket.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1,2 and Fig. 3, the embodiment of the present invention comprises:
A kind of spanner, is characterized in that, comprising: wrench body 1, described wrench body 1 for two ends be the stereochemical structure of arc-shaped, described wrench body 1 two ends are provided with bayonet socket 2, and described bayonet socket 2 has 4, and two ends respectively arrange two, described bayonet socket 2 is the regular hexagon structure closed, interior angle is 120 °, and wherein, the specifications and models of four bayonet sockets 2 are all different, two bayonet sockets 2 of any one end are a large bayonet socket 2 and little bayonet socket 2 combination collocation, and the degree of depth of each bayonet socket 2 is identical.
Be different from prior art.
In another embodiment, the making material of described wrench body 1 is chrome-vanadium steel, and hardness is large, long service life.
In another embodiment, the specification of described bayonet socket 2 can be 7,10,12,14,17,19,22,24, and any four kinds of specifications can be arranged in pairs or groups making.
In another embodiment, the thickness of described wrench body 1 is 2cm.
In another embodiment, the degree of depth of described bayonet socket 2 is the half of described wrench body 1 thickness, is 1cm, to be independent of each other use at two bayonet sockets of any one end.
Structure of the present invention is simple, reasonable in design, adopts the non-interfering feature of size bayonet socket, the regular hexagon bayonet socket of four different models is set at spanner two ends, complete function, practical, bolt or the nut assembly of Multiple Type can be mated, have certain economic benefit and market prospects.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
