As shown in Figures 2 and 3, spanner head assembly 400 includes：Driving end 410, positioning bead 420, spanner spring 430, rotation
Axle 440 and the second jump ring 450.
The front end of driving end 410 is wrench operated end 411, and rear end profile is regular hexagon 412, also with centre bore 413
With location hole 414, tail end has fixed card slot 415.Each side of regular hexagon 412 has escape groove 416, and escape groove 416 exists
The center on each side.Location hole 414 is perpendicular to centre bore 413 and in the position of operating side 411；Location hole 414 it is straight
Diameter of the footpath less than positioning bead 420.
The point diameter of rotary shaft 440 is matched with centre bore 413, and rear end diameter is big；Front end has locating slot 441, positioning
The front end of groove 441 is inclined-plane.440 front end of rotary shaft passes through stop sleeve 510, is then passed through spanner spring 430；Positioning bead 420 is put
Put in locating slot 441, in insertion centre bore 413, the second jump ring 450 is embedded in fixed card slot 415.Positioning bead 420 is in spanner
In the presence of spring 430, it is partially in location hole 414.
Stop assembly 500 includes：Stop sleeve 510 and 6 latch 520.Outside the quantity and driving end 410 of latch 520
The quantity of shape regular polygon is identical.
Stop sleeve 510 circumference uniform distribution, 6 locking grooves 511, and correspond with latch 520, latch 520 is only arranged on
In dynamic groove 511.
Stop sleeve 510 is enclosed within driving end 410,413 1 sides of regular polygon of fitting on the inside of each latch 520, outside
The inwall of laminating rotating hole 310.
Fig. 4 is the rear exploded view of novel ratchet spanner.
As shown in Figure 3 and Figure 4, transition components 700 include：Three conversion pearls 610 and three throw over springs 620.
Stop sleeve 510 is with 3 conversion holes 512.Conversion pearl 610, throw over spring 620, conversion hole 512 correspond, and
Circumference uniform distribution.
Driving end 410 has the conversion groove group 417 of 6 groups of circumference uniform distributions, is arranged on and 510 sides adjacent of stop sleeve.Conversion groove
Group 417 is two neighboring conversion groove 417；Radius of the depth of conversion groove 417 less than conversion pearl 610.Throw over spring 620 is arranged on
In conversion hole 512, conversion pearl 610 is arranged in throw over spring 620 and a conversion groove 417.
Rotation stop sleeve 510, conversion pearl 610 receive torsion, and throw over spring 620 is compressed, into another adjacent turn
Change groove 417.
Conversion groove group 417 actually used herein only needs to 3 groups, with conversion pearl 610, throw over spring 620, conversion hole 512
Correspond.It is on driving end 410 to arrange 3 groups more, avoid the need for being accurately positioned during installation, conversion pearl 610 is automatic
Into in corresponding conversion groove 417.The quantity of conversion groove group is the multiple of transition components 600.
The operation principle of novel ratchet spanner：
Fig. 5 is the rotate counterclockwise state diagram that novel ratchet spanner removes front shroud.
As shown in figure 5, when 300 rotate counterclockwise of handle of novel ratchet spanner, latch 520 is subject to rotatable handle hole
The pressure of inwall, the driving end of regular hexagon 412 stop that frictional force between the two is big.Latch, stop sleeve and driving end are only
Can be with 300 rotate counterclockwise of handle of novel ratchet spanner.
When the handle 300 of novel ratchet spanner turns clockwise, latch to size it is big where rotate, frictional force subtracts
Little, relative between latch, stop sleeve and handle 300 to slide, driving end 410 is not with 300 up time of handle of novel ratchet spanner
Pin rotates.
It is the rear end for turning stop sleeve to need to convert direction of rotation, and conversion pearl 610 is received torsion, and throw over spring 620 is received
Compression, into another adjacent conversion groove 417, driving end rotates a certain angle with respect to stop sleeve, by novel ratchet spanner
The state of Fig. 6 is switched to from the state of Fig. 5.
Fig. 6 is the suitable pin rotation status figure that novel ratchet spanner removes front shroud.
In the same manner, as shown in fig. 6, when the handle 300 of novel ratchet spanner turns clockwise, latch 520 is subject to handle
The pressure of rotating hole inwall, the driving end of regular hexagon 412 stop that frictional force between the two is big.Latch, stop sleeve and pull
At hand can only be with 300 rotate counterclockwise of handle of novel ratchet spanner.
When 300 rotate counterclockwise of handle of novel ratchet spanner, latch to size it is big where rotate, frictional force subtracts
Little, relative between latch, stop sleeve and handle 300 to slide, driving end 410 is not with 300 inverse time of handle of novel ratchet spanner
Pin rotates.
Variation
Novel ratchet spanner in embodiment one, uses 6 latch and orthohexagonal structure is combined.New spine
Wheel spanner can set the latch of varying number and polygonal combination, do not limit according to the size of spanner and the size of force
Structure in embodiment one.
