Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
As illustrated, the present invention includes wrench body 1, described 1 one end of spanner is double offset ring spanner at hand 8, described plum blossom
Driving end 8 includes an installing hole 6 and accommodating cavity 12, is provided with torsion circle 7 in described installing hole 6, and described 7 bottom of torsion circle sets
There is jacking block 10, described jacking block 10 is placed in 12 side of accommodating cavity, and described 12 opposite side of accommodating cavity is provided with spring 9, described bullet
9 one end of spring is peaked on jacking block 10, and the other end is peaked on the internal face of accommodating cavity 12.
Described torsion circle 7 can be relatively rotated in installing hole 6, and described torsion circle 7 and jacking block 10 are formed in one knot
Structure.
Described installing hole 6 is connected with accommodating cavity 12, is shelves point 11 on the right side of the position of described connection, described accommodating cavity
12 is " ﹄ " structure, and described " ﹄ " structure upper has certain length S1.
Described shelves point 11 to the internal face on the right side of accommodating cavity 12 apart from S more than or equal to 12 maximum compression of spring away from
From failing so as to prevent spring 12 to be overly compressed.After spring reaches maximum compression, due to the effect of shelves point 11, jacking block 10
No longer displacement, fails so as to prevent spring 12 to be overly compressed.
The torsion circle of the position that described 10 rearward end of jacking block is intersected 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.
Described exerted a force scope indicating area（14,15）, the scope that can not exert a force indicating area（16,17）And limit range
Indicating area 13 is located at below arrow 5.
Polygon engagement mouth of described 7 inwall of torsion circle for fitted bolt head.The polygonized structure of 7 inwall of torsion circle
As common spanner interior wall construction.
Embodiment 1：Such as Fig. 6-8, it is M10*1.5P that patent of the present invention is, for example, bolt specification, and bolt grade is 8.8 grades,
Minimum breakdown torque is set to 66N.m, when the double offset ring spanner headgear is exerted a force on bolt, as the effect of power is phase
Mutually, when force is turned left from the right side to spanner, the power that bolt can be to torsion circle from left to right, so as to drive torsion circle from left to right
Rotation, torsion circle rotarily drive jacking block rotation, so as to jacking block is by spring-compressed, when the power to spanner gradually increases, jacking block
To spring-compressed is bigger, the swing offset of its torsion circle is bigger, and arrow is constantly moved from left to right, due to indicator
Head lower section is provided with direction board, and arrow locations movement is moved to from the scope indicating area that can exert a force when can not exert a force scope indicating area
Wait it is necessary to stop exerting oneself, if continuing to exert oneself, arrow locations will be moved into limit range indicating area, now, may destroy
Bolt torque, as the present invention is provided with a grade point, although so the present invention no matter apply external force, after jacking block peaks at shelves point, its
Jacking block would not be subjected to displacement, due to being provided with a grade point, so invention prevents spring is overly compressed and fails.Fig. 6 is indicated
In the scope indicating area that can exert a force, Fig. 7 arrows are in the scope indicating area that can not exert a force to arrow, at Fig. 8 arrows
In limit range indicating area.
Embodiment 2：Such as Fig. 9-11, bolt specification is M10*1.5P, and bolt grade is 12.9 grades, and minimum breakdown torque sets
For 90N.m；When the double offset ring spanner headgear is exerted a force on bolt, due to the effect of power be it is mutual, when to spanner from
The right side is turned left when exerting a force, the 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
Jacking block rotation is rotarily driven, so as to 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 is constantly moved from left to right, as instruction is provided with below arrow
Board, arrow locations movement are moved to from the scope indicating area that can exert a force when can not exert a force scope indicating area it is necessary to stop 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 present invention is provided with a grade point, although so of the invention no matter applying external force, after jacking block peaks at shelves point, its jacking block would not occur
Displacement, due to being provided with a grade point, so invention prevents spring is overly compressed and fails.Fig. 9 arrows are in and can exert a force
Scope indicating area, Figure 10 arrows refer in limit range in the scope indicating area that can not exert a force, Figure 11 arrows
Show region.
