Abstract
A kind of blossom type open-end wrench, comprise wrench body, handle, opening, wrench body is rounded, the periphery of wrench body is also provided with handle, handle is integrated with wrench body and is connected, opening is arranged in wrench body, and wrench body is also provided with plum blossom opening, and opening parallels setting with orthohexagonal two parallel edges of plum blossom opening.The utility model is by changing common spanner into blossom type endoporus, connect from being applicable to compacter pipeline, simultaneously, opening portion in wrench body is added chamfered part, thus further less space required when using, can joint on arbitrary pipeline in dismounting or the compact fluid pressure line of fastening inspection, and the pipeline of outside need not be dismantled, save the repair time, saving the waste of the hydraulic oil caused because disconnecting head more, also avoid the situation that pollution because dismounting joint may cause or sealing property decline.
Description
Technical field
The utility model belongs to professional tool field, especially relates to a kind of blossom type open-end wrench.
Background technology
Plum blossom spanner and opening spanner are all daily general instruments, and wherein plum blossom spanner two ends are garland shape, and its endoporus is mutually staggered with one heart 30 ° by 2 regular hexagons to form.A lot of double offset ring spanner has elbow, and common angle of bend is between 10 ° ~ 45 °, and swivel bolt part and handle portion stagger from the side.This structure is convenient to dismantle the bolt, the nut that are assemblied in dented space, and can provide operating clearance for finger, to prevent scratch.Being used in supplement tightens with in similar operations, and double offset ring spanner can be used to apply high pulling torque to bolt or nut.Double offset ring spanner has all size, will select the spanner corresponding with bolt or nut size during use.Because jaw of spanner is bihexagon, can easily assembling bolt/nut.This can reinstall in a confined space.Its main feature is: be applicable to working space narrow and small, can not use the occasion of common wrench.
Open-end wrench is generally used for twisting bolt, screw, nut and other screw threads and tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
Use hydraulic powers as in the arranging of power unit at some, the circuit design of hydraulic valve platform is all compact, joint that is that have or even that do not dismantle outside and pipeline, cannot joint inside dismounting or pipeline, and existing instrument, common opening spanner size is large, and work angle is 60 °, and plum blossom spanner size is little, but there is no opening, cannot be used for fluid pressure line, so, difficulty can be very large sometimes in the service work of fluid pressure line.
Utility model content
Problem to be solved in the utility model is the problem overcoming prior art, and body weight is a kind of can be the spanner used in compact pipeline equipment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of blossom type open-end wrench, comprise wrench body, handle, opening, it is characterized in that: described wrench body is rounded, the periphery of wrench body is also provided with handle, handle is integrated with wrench body and is connected, described opening is arranged in wrench body, described wrench body is also provided with plum blossom opening, described plum blossom opening by two in the same center of circle, the regular hexagon that circumscribed circle diameter is identical cuts out, opening parallels setting with orthohexagonal two parallel edges of plum blossom opening.
Concrete, the periphery of described wrench body and opening is also provided with chamfering.
Concrete, described two regular hexagons rotate 30 degree relative to the center of circle.
Concrete, orthohexagonal two of described and opening parallel are also parallel to each other between limit and handle.
Concrete, described and opening parallel orthohexagonal two between limit and handle in the angle of 9 degree.
The advantage that the utility model has and good effect are: a kind of blossom type open-end wrench, by changing common spanner into blossom type endoporus, connect from being applicable to compacter pipeline, simultaneously, opening portion in wrench body is added chamfered part, thus further less space required when using, can joint on arbitrary pipeline in dismounting or the compact fluid pressure line of fastening inspection, and the pipeline of outside need not be dismantled, save the repair time, saved the waste of the hydraulic oil caused because disconnecting head more, also avoid the situation that pollution because dismounting joint may cause or sealing property decline.
Accompanying drawing explanation
Fig. 1 is that staight shank connects spanner schematic diagram;
Fig. 2 is that oblique handle connects spanner schematic diagram.
In figure: 1 wrench body, 2 openings, 3 plum blossom openings, 4 handles, 5 chamferings.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of blossom type open-end wrench as shown in Figure 1 and Figure 2, comprises wrench body 1, opening 2, handle 4.Wrench body 1 is the object of a similar circle, has also cut that two circumscribed circle diameters are identical, the regular hexagon of angle difference 30 degree at the home position place of wrench body 1, and two regular hexagons are plum blossom opening 3 in wrench body.In wrench body 1, be also provided with opening 2, the size of opening 2 is identical with the distance between hexagonal two parallel edges simultaneously.Like this, the advantage of common open-end wrench and double offset ring spanner is combined, not only can not be used in environment less, when having a limitation, can also be used in that environment is little, in pipeline environment when having a limitation.Opening 2 with the contact position of wrench body 1 are also provided with chamfering 5, and chamfering 5 not only further can reduce the length stretched into of spanner, and spanner can also be allowed more convenient when turning.
Wrench body is also provided with handle 4, handle 4 be provided with two kinds of modes:
Mode one
A kind of blossom type open-end wrench as shown in Figure 1, wrench body 1 is provided with handle 4, is parallel to each other between the side of handle 4 and the limit of opening 2.
Mode two
A kind of blossom type open-end wrench as shown in Figure 2, wrench body 1 is provided with handle 4, there is certain angle between the side of handle 4 and the limit of opening 2, and the angle between both sides is 9 degree.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
