As shown in fig. 7, toggle 3 includes driving lever 31 and rotation column 32, the setting of spring block 7 is on rotation column 32,13 lower part of toggle groove
Equipped with the limiting slot 14 being connected to toggle groove 13,32 one end of rotation column is inserted into toggle groove 13, and driving lever 31 is located in limiting slot 14, with
Tooth block 6 is pushed to the position that deviation is engaged with ratchet 2 by spring block 7 caused by preventing 31 rotation amplitude of driving lever excessive, is ensured
Stable engagement between tooth block 6 and ratchet 2.The rotation column other end can extend into arc regulating tank 62 and match with arc adjusting groove groove wall
It closes.Groove groove wall force further is adjusted to arc by rotating end, with spring block collective effect so that tooth block and ratchet external tooth
Between transmission more stablize, efficiently.
When needing to install the ratchet wrench head, installation personnel is first by ratchet 2 from the one of 1 through-hole 11 of pawl seat
End is inserted into, and the collar flange 112 on ratchet 2 is resisted against on the rear end face of pawl seat 1, and spring is then put into pushing block
In shrinkage pool 71 inside 72, and pushing block 72 and spring are put into the slot 33 in 32 center of rotation column；It again will be in control assembly
Tooth block 6, spring block 7 and toggle 3 are put into the storage tank 12 on 1 surface of pawl seat, and the installation of control assembly is just completed；Then
Pressing plate 5 is placed into the front end of ratchet 2, and is snapped onto in annular groove 22 by snap ring so that snap ring can fix pressing plate 5
In the outside of ratchet 2；So that pressing plate 5 is packed into annular recessed shoulder 111, and pressing plate 5 is made to be resisted against the cascaded surface of annular recessed shoulder 111
It on 131, then is caught in the annular groove 22 on 2 surface of ratchet by spacing ring 4 and ratchet 2 is fixed, complete the ratchet spanner
Head whole fixation and installation.
Axis is carried out to ratchet 2 by the spacing ring 4 of the collar flange 112 of 2 one end of ratchet and the other end in the present embodiment
It avoids ratchet 2 the case where sliding or falling off occur to avoid ratchet 2 from the case where play occur to limit, increases user
To the using effect of the ratchet wrench head, the usage time of the ratchet wrench head is also improved.Meanwhile the shape of this kind of single side assembly
Formula facilitates Fast Installation of the installation personnel to the ratchet wrench head, improves the installation effectiveness of installation personnel.
The tooth of latch 61 is towards difference on tooth block 6, and works as the arc regulating tanks 62 of spring block 7 or so and 66 bottom of tooth block
When, tooth block 6 can be made to tilt to the left or to the right, when spring block 7 acts on arc 62 left side of regulating tank, tooth block 6 is tilted to the right,
Ratchet 2 can rotate counterclockwise at this time, locked clockwise；When spring block 7 acts on arc 62 right side of regulating tank, tooth block
6 are tilted to the left, and ratchet 2 can rotate clockwise at this time, counterclockwise locked, to be realized to ratchet by the control assembly
The external tooth 21 in 2 outsides engages direction and is controlled, and ratchet 2 is made to have the function of controlling bidirectional rotation, improves user to the spine
The using effect of wheel spanner.
In the present embodiment on the one hand the set-up mode of 1 middle through-hole 11 of pawl seat and storage tank 12 changes conventional spine
The structure type and processing method of wheel spanner allow processing staff to be not necessarily to carry out hole milling operation to pawl seat 1, only need to be by pawl seat 1
A punching press, that is, plastic is carried out, the processing convenience of processing staff is improved, on the other hand, using this kind of assembling form,
Fast Installation of the installation personnel to the ratchet wrench head is facilitated, the installation effectiveness of installation personnel is improved, effectively reduces ratchet 2
Gap between 1 inner surface of surface external tooth 21 and pawl seat, so that the latch of the external tooth 21 and tooth block 6 of 2 outer surface of ratchet
Engagement between 61 is more complete, then so that the torsion of spanner increases substantially, and traditional pawl seat 1, by table in the inner
Face uses the form of plane, and the gap between 2 external tooth 21 of ratchet and 1 inner surface of pawl seat is larger, and torsion is smaller, experiment card
Bright, compared to traditional pawl seat 1 for not using cascaded surface 131, torsion improves 40% or more.
Embodiment 2
Ratchet spanner, as shown in figure 9, including plate body 10, the unidirectional fixed ratchet being connected on plate body 10 in embodiment 1
Driving end.
Embodiment 3
With embodiment 1, as shown in Figure 10, except that pawl seat 1 is stretched out at the both ends of ratchet 2 in the present embodiment, make
Obtain the spanner only needs ratchet portions to stretch into operating position when in use, is all stretched into without entire ratchet wrench head, is pulled to improve
The application place of hand.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the claims institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
