Abstract
The utility model provides a simple structure, conversion make things convenient for, can deal with the novel bolt fastening spanner of multiple model bolt. A novel bolt fastening spanner, includes the handle, the one end of handle or both ends are provided with the pivot, the the central axis of pivot is perpendicular with the length direction that the handle belonged to, be provided with solid wrench end in the pivot, the wrench end is regular polyhedron, be provided with the screw draw -in groove that the size is different on every side of wrench end. Simple structure, convenient, the swift characteristics of conversion along with the rotation of wrench end, can set up the screw draw -in groove that matches with the hex bolts head of multiple model simultaneously on instrument, the integrated level that has improved the instrument work efficiency during with the construction.
Description
Technical field
This utility model relates to a kind of Novel bolt spanner, is widely used in the fastening of different model bolt during power system site operation, belongs to electric power construction field technical field.
Background technology
Spanner is a kind of conventional installation and extracting tool.It generally makes grip bolt or the opening of nut or trepanning in the one or both ends of shank.Utilizing lever principle during use, threadingly direction of rotation applies external force at spanner shank, it becomes possible to twist bolt or nut.
Phase of Electric Power Projects scene needs to fasten the bolt of different model, and main tool is the stiff hands of opening, double offset ring spanner or box spanner.The bolt of 2 kinds of models can be fastened by one stiff hands of opening or double offset ring spanner, and box spanner needs to change collet head according to different bolt models, and this means that site operation personnel need to carry many wrench or collet head.Aloft during operation, workmen bears more instrument and causes very big inconvenience to work high above the ground.If the instrument model carried is the most right, in addition it is also necessary to tool for transmitting upper and lower with ground staff, reduces work efficiency, transmittance process is also easy to bring potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned instrument to provide a kind of simple in construction, conversion convenient, can tackle the Novel bolt spanner of Multiple Type bolt.
Technical solution of the present utility model is:
A kind of Novel bolt spanner, including handle, it is characterized in that one end of described handle or two ends are provided with rotating shaft, the central axis of described rotating shaft is vertical with the length direction at handle place, solid driving end it is provided with in described rotating shaft, described driving end is regular polygon, and each of described driving end is provided with the screw draw-in groove that size is different.
Further, driving end includes two bottom surfaces parallel to each other and multiple side, and described side is rectangle, and described bottom surface is regular polygon, and the central axis of described driving end overlaps with rotating shaft.Preferably, driving end selects regular hexahedron.
Further, above-mentioned rotating shaft is fixedly connected on handle, and described driving end can rotate around the axis.Or above-mentioned rotating shaft is movably connected on handle, described driving end is fixedly connected in rotating shaft.
Further, above-mentioned handle can use yi word pattern handle；Can also arrange heel in one end of handle or two ends, the angle of bend of described heel is 10 °-45 °, and described rotating shaft is positioned in heel, and the design of this heel is similar with existing double offset ring spanner, may be used for the bolt loading and unloading of recess.
This utility model has compared with the prior art: simple in construction, change convenient, fast, rotation along with driving end, the screw draw-in groove that hexagonal bolt head with Multiple Type mates can be set on one instrument simultaneously, improve work efficiency during integrated level and the construction of instrument.

Detailed description of the invention
Below in conjunction with the accompanying drawings using method of the present utility model is elaborated.
A kind of Novel bolt spanner, it is made up of handle 1, rotating shaft 2, driving end 3, screw draw-in groove 4.The two ends of handle are provided with rotating shaft, the central axis of rotating shaft is vertical with the length direction at handle place, solid driving end it is provided with in rotating shaft, described driving end includes two bottom surfaces 5 parallel to each other and multiple side 6, described side 6 is rectangle, described bottom surface 5 is square, and the central axis of described driving end overlaps with rotating shaft, and each side of described driving end is provided with the screw draw-in groove that size is different.
Embodiment one: see Fig. 1-3, the handle 1 of steel is connected by the rotating shaft 2 of steel with the driving end 3 of steel, driving end 3 is regular hexahedron, and on four sides of steel driving end 3, each interior milling goes out the regular hexagon inner groovy of a specification and can use yi word pattern handle as screw draw-in groove 4, handle.Above-mentioned rotating shaft is fixedly connected on handle, and described driving end can rotate around the axis.During use, rotate steel driving end 3 according to bolt model and choose corresponding screw draw-in groove 4, bolt head is stuck in screw draw-in groove 4, pulls pinch bar 1 fastening bolt.
In this embodiment, a Novel bolt spanner can tackle the bolt loading and unloading of 8 kinds of models.
Embodiment two: driving end 3 can also use structure as shown in Figure 4, described driving end includes two bottom surfaces 5 parallel to each other and 5 sides 6, side 6 is rectangle, bottom surface 5 is regular pentagon, the central axis of described driving end overlaps with rotating shaft, and 5 sides of described driving end are provided with the screw draw-in groove that size is different.Above-mentioned rotating shaft is movably connected on handle, and described driving end is fixedly connected in rotating shaft.Arrange heel in one end of handle or two ends, the angle of bend of described heel is 10 °-45 °, and described rotating shaft is positioned in heel, and the design of this heel is similar with existing double offset ring spanner, may be used for the bolt loading and unloading of recess.
This Novel bolt spanner can tackle the bolt loading and unloading of 10 kinds of models.
