When offseting, torsional spring deforms upon, and to after to a certain degree, torsional spring pushes linkage block rotation, linkage block to drive eccentric shaft for torsional spring deformation
Rotation, eccentric shaft drives pushing block to be rotated in linkage rack, and to drive linkage rack to swing, linkage rack drives ratchet circle to swing, spine
Wheel rim swings by the rotation of coupled ratchet driving rotating bodies, and then drives export head rotation, realizes power output.Work as ratchet spanner
By it is electronic be switched to manual when, motor stalls, so that transmission shaft, drive block, linkage block and pushing block stop turning in succession
It is dynamic, it is in " dead point " position when if pushing block stopping at this time, then torsional spring can be made to deform upon in rotation due to drive block,
When being in " dead point " position when pushing block stops, torsional spring elastic reset, torsional spring can offset when resetting with linkage block to push linkage
Block rotates, and linkage block rotation can drive eccentric shaft turns, to drive pushing block to deviate " dead point " position, in order to which spine is manually operated
Wheel spanner, and during ratchet is manually operated, the inner wall of handle is in contact with linkage rack outer wall, to drive linkage rack
Rotation, linkage rack rotation can be contacted with pushing block to drive pushing block to rotate, and pushing block rotation drives linkage block rotation, linkage block to rotate
Cheng Zhong can offset with torsional spring to push torsional spring to rotate, and torsional spring turns to when offseting with drive block, and torsional spring deforms upon, torsional spring shape
After fading to a certain degree, torsional spring pushes drive block rotation, and drive block is by driving transmission shaft to dally, when pushing block is moved at " dead point "
When position, torsional spring elastic reset, torsional spring can offset to push linkage block to rotate when resetting with linkage block, and linkage block rotation can drive
Eccentric shaft turns, to drive pushing block to deviate " dead point " position, therefore the present invention can substantially reduce the opposite linkage of eccentric pushing block
The stuck probability of frame, does not interfere with the using effect of ratchet spanner.
Ratchet spanner is in commutation, if the output end of rotary body is to rotate forward, turns to turn round by rotating backward, revolve at this time
The output end of swivel will not be dynamic with torsion is turned, and turns twisted strip and moves reversing piece rotation, the first end rotation of reversing piece pushes linkage
Pawl is rotated around installation axle so that ratchet and ratchet circle positioned at coupled ratchet with the matched one end of reversing piece first end are nibbled
It closes, the ratchet and ratchet circle for being located at the coupled ratchet other end are detached from, and the end face of one end of the separate ratchet circle of coupled ratchet
It is inconsistent with the respective stopping face of mounting groove, that is, the limit to coupled ratchet is realized, at this point, ratchet circle is in anti-with coupled ratchet
To linkage, positive slipping state, i.e., when ratchet circle rotates backward, ratchet circle can be rotated by coupled ratchet driving rotating bodies, and
It when ratchet circle rotates forward, skids between ratchet circle and coupled ratchet, rotary body will not rotate, and it is defeated that export head is unpowered
Go out.Smoothly realize and rotated backward by rotating forward to be switched to, similarly, when rotate forward turn to turn round when, ratchet circle and coupled ratchet are just
In positive direction linkage, reversed slipping state.Compared with prior art, it only needs singlehanded directly rotation turn torsion that can realize when commutation to change
To increase work smoothness improves work efficiency, and reversing piece pushes directly on coupled ratchet rotation, without along connection
The side of pawl is opposite to be slided, and to reduce the abrasion of reversing piece, extends the service life of reversing piece, dependable performance.

Turn turns round 12, and the output end of rotary body 3 will not turn to turn round the 12 drive rotations of reversing pieces 123, reversing piece with 12 rotation of turn torsion at this time
123 rotation of first end 124 pushes coupled ratchet 4 to be rotated around installation axle 11 so that is located at coupled ratchet 4 and reversing piece 123
The ratchet 41 of the matched one end of first end is engaged with ratchet circle 2, is located at the ratchet 41 and ratchet circle 2 of 4 other end of coupled ratchet
It is detached from, and the end face of one end of the separate ratchet circle 2 of coupled ratchet 4 and the respective stopping face 321 of mounting groove 32 are inconsistent, i.e.,
The limit to coupled ratchet 4 is realized, at this point, ratchet circle 2 is in reversed linkage, positive slipping state, i.e. ratchet with coupled ratchet 4
When rotating backward, ratchet circle 2 can be rotated circle 2 by 4 driving rotating bodies 3 of coupled ratchet, and when ratchet circle 2 rotates forward, ratchet
It skids between circle 2 and coupled ratchet 4, rotary body 3 will not rotate, 31 unpowered output of export head.Smoothly realize by forward direction
Rotation is switched to and rotates backward, similarly, when rotate forward turn to turn round 12 when, ratchet circle 2 be just in coupled ratchet 4 positive direction linkage,
Reversed slipping state.Compared with prior art, commutation can be realized by only needing singlehanded directly rotation to turn torsion 12 when commutation, increase work
Smoothness improves work efficiency, and reversing piece 123 pushes directly on the rotation of coupled ratchet 4, without along coupled ratchet 4
Side it is opposite slide, to reduce the abrasion of reversing piece 123, extend the service life of reversing piece 123, dependable performance.
