Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
As shown, the present invention includes wrench body 1, described 1 one end of spanner is double offset ring spanner at hand 8, the plum blossom
Driving end 8 includes a mounting hole 6 and accommodating cavity 12, is equipped with torsion circle 7 in the mounting hole 6,7 lower part of torsion circle is set
There is jacking block 10, the jacking block 10 is placed in 12 side of accommodating cavity, and 12 other side of accommodating cavity is equipped with spring 9, the bullet
9 one end of spring peaks on jacking block 10, and the other end peaks on the inner wall of accommodating cavity 12.
The torsion circle 7 can relatively rotate in mounting hole 6, and the torsion circle 7 and jacking block 10 are integrally formed knot
Structure.
The mounting hole 6 is connected to accommodating cavity 12, is shelves point 11, the accommodating cavity on the right side of the position of the connection
12 be " ﹄ " structure, and " ﹄ " structure upper has certain length S1.
The shelves point 11 to the right side of accommodating cavity 12 inner wall distance S be greater than or equal to 12 maximum compression of spring away from
From so that spring 12 be prevented to be overly compressed and fail.After spring reaches maximum compression, due to the effect of shelves point 11, jacking block 10
It is no longer displaced, so that spring 12 be prevented to be overly compressed and fail.
The torsion circle for the position that 10 rear end of jacking block is intersected with torsion circle 7 is equipped with arrow 5.
The double offset ring spanner is external at hand to be equipped with holddown plate 2, and the holddown plate 2 is equipped with direction board 3.
The holddown plate 2 uses screw 4 to connect at hand with double offset ring spanner.
The direction board 3 is torque gear direction board, including the range indicating area (14,15) that can exert a force, can not be exerted a force
Range indicating area (16,17) and limit range indicating area 13.
The range indicating area (14,15) that exerts a force, the range that can not exert a force indicating area (16,17) and the limit range
Indicating area 13 is located at 5 lower section of arrow.
7 inner wall of torsion circle is that the polygon of fitted bolt head engages mouth.The polygonized structure of 7 inner wall of torsion circle
As common spanner interior wall construction.
Embodiment 1: such as Fig. 6-8, the invention patent is, for example, that bolt specification is M10*1.5P, and bolt grade is 8.8 grades,
Minimum breakdown torque is set as 66N.m, when the double offset ring spanner headgear on bolt when being exerted a force, since the effect of power is phase
Mutually, when turn left to spanner from the right side exert a force when, bolt can give the power of torsion circle from left to right, to drive torsion circle from left to right
Rotation, the rotation of torsion circle drive jacking block rotation, so that jacking block is by spring-compressed, when the power to spanner is gradually increased, jacking block
To spring-compressed is bigger, the swing offset of torsion circle is bigger, and arrow will be moved constantly from left to right, due to indicator
Head lower section is equipped with direction board, and arrow locations movement is moved to when can not exert a force range indicating area from the range indicating area that can exert a force
It waits it is necessary to stop exerting oneself, if continuing to exert oneself, arrow locations will be moved into limit range indicating area, at this point, may destroy
Bolt torque, due to the present invention be provided with shelves point, although so the present invention regardless of apply external force, after jacking block peaks at shelves point,
Jacking block would not be subjected to displacement, due to being equipped with shelves point, so being overly compressed and failing invention prevents spring.Fig. 6 instruction
Arrow is in the range indicating area that can exert a force, and Fig. 7 arrow is at the range indicating area that can not exert a force, Fig. 8 arrow
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 mutually, when to spanner from
The right side is turned left when exerting a force, and bolt can give the power of torsion circle from left to right, so that torsion circle is driven to rotate from left to right, torsion circle
Rotation drives jacking block rotation, so that jacking block is by spring-compressed, when the power to spanner is gradually increased, jacking block is got over to by spring-compressed
Greatly, the swing offset of torsion circle is bigger, and arrow will be moved constantly from left to right, due to being equipped with instruction below arrow
Board, arrow locations are mobile to be moved to when can not exert a force range indicating area it is necessary to stopping using from the range indicating area that can exert a force
Power, if continuing to exert oneself, arrow locations will be moved into limit range indicating area, at this point, bolt torque may be destroyed, due to
The present invention is provided with shelves point, although after jacking block peaks at shelves point, jacking block would not occur so the present invention is regardless of applying external force
Displacement, due to being equipped with shelves point, so being overly compressed and failing invention prevents spring.Fig. 9 arrow is in and can exert a force
Range indicating area, Figure 10 arrow are in the range indicating area that can not exert a force, and Figure 11 arrow refers in limit range
Show region.
