Embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
As illustrated, the utility model includes wrench body 1, described one end of spanner 1 is double offset ring spanner at hand 8, described
Double offset ring spanner 8 includes a mounting hole 6 and accommodating cavity 12 at hand, is provided with torsion circle 7 in described mounting hole 6, under described torsion circle 7
Portion is provided with jacking block 10, and described jacking block 10 is placed in the side of accommodating cavity 12, and the described opposite side of accommodating cavity 12 is provided with spring 9, described
The one end of spring 9 peak on jacking block 10, the other end is peaked on the internal face of accommodating cavity 12.
Described torsion circle 7 can relatively rotate in mounting hole 6, and described torsion circle 7 and jacking block 10 are formed in one knot
Structure.
Described mounting hole 6 connects with accommodating cavity 12, is shelves point 11 on the right side of the position of described connection, described accommodating cavity
12 be " ﹄ " structure, and described " ﹄ " structure upper has certain length S1.
The distance S of described shelves point 11 to the internal face on the right side of accommodating cavity 12 be more than or equal to the maximum compression of spring 12 away from
From so as to prevent that spring 12 is overly compressed and is failed.After spring reaches maximum compression, due to the effect of shelves point 11, jacking block 10
No longer displacement, so as to prevent that spring 12 is overly compressed and is failed.
The torsion circle for the position that the described rearward end of jacking block 10 intersects with torsion circle 7 is provided with arrow 5.
Described double offset ring spanner is outside at hand to be provided with holddown plate 2, and described holddown plate 2 is provided with direction board 3.
Described holddown plate 2 is connected using screw 4 at hand with double offset ring spanner.
Described direction board 3 is moment of torsion gear direction board, including the scope indicating area that can exert a force（14,15）, can not exert a force
Scope indicating area（16,17）With limit range indicating area 13.
The described scope indicating area that exerts a force（14,15）, the scope that can not exert a force indicating area（16,17）And limit range
Indicating area 13 is located at the lower section of arrow 5.
The described inwall of torsion circle 7 engages mouth for the polygon of fitted bolt head.The polygonized structure of the inwall of torsion circle 7
As common spanner interior wall construction.
Embodiment 1：Such as Fig. 6-8, the utility model patent is, for example, that bolt specification is M10*1.5P, and bolt grade is 8.8
Level, minimum breakdown torque is set to 66N.m, when the double offset ring spanner headgear on bolt when being exerted a force, due to the work of power
With being mutual, when force is turned left from the right side to spanner, power that bolt can be to torsion circle from left to right, so as to drive torsion circle from
Rotate from left to right, the rotation of torsion circle drives jacking block rotation, so as to which jacking block is by spring-compressed, when the power to spanner gradually increases
When, for jacking block to spring-compressed is bigger, the swing offset of its torsion circle is bigger, and arrow will be moved constantly from left to right, by
Direction board is provided with below arrow, arrow locations movement is moved to the scope that can not exert a force from the scope indicating area that can exert a force and referred to
It is necessary to stop exerting oneself when showing region, if continuing to exert oneself, arrow locations will be moved into limit range indicating area, now, can
Bolt torque can be destroyed, because the utility model is provided with shelves point, so the utility model is although no matter application external force, works as top
After block peaks at shelves point, its jacking block would not be subjected to displacement, due to provided with shelves point, so the utility model prevents spring excessive
Compress and fail.Fig. 6 arrows are in the scope indicating area that can exert a force, and Fig. 7 arrows are in the scope instruction that can not exert a force
Region, Fig. 8 arrows are in limit range indicating area.
Embodiment 2：Such as Fig. 9-11, bolt specification M10*1.5P, bolt grade is 12.9 grades, and minimum breakdown torque is set
For 90N.m；When the double offset ring spanner headgear on bolt when being exerted a force, due to the effect of power be it is mutual, when to spanner from
The right side turn left force when, power that bolt can be to torsion circle from left to right, so as to drive torsion circle to rotate from left to right, torsion circle
Rotation drives jacking block rotation, and so as to which jacking block is by spring-compressed, when the power to spanner gradually increases, jacking block is to spring-compressed is got over
Greatly, the swing offset of its torsion circle is bigger, and arrow will be moved constantly from left to right, due to being provided with instruction below arrow
Board, arrow locations movement are moved to when can not exert a force scope indicating area from the scope indicating area that can exert a force it is necessary to stopping using
Power, if continuing to exert oneself, arrow locations will be moved into limit range indicating area, now, may destroy bolt torque, due to
The utility model is provided with shelves point, so the utility model is although no matter apply external force, after jacking block peaks at shelves point, its jacking block is just
It will not be subjected to displacement, due to provided with shelves point, so the utility model prevents spring to be overly compressed and fail.Fig. 9 indicators
Head is in the scope indicating area that can exert a force, and Figure 10 arrows are at the scope indicating area that can not exert a force, Figure 11 arrows
In limit range indicating area.
