This driving lever 30, this driving lever 30 is formed with a clicking section 31 and a fixed leg 32, this fixed leg 32 is provided with one and fastens in the fitting portion 33 of this moving part 22 draw-in grooves 224 towards differing from these clicking section 31 directions, and this fixed leg 32 is concaved with an annular groove 34 in outer peripheral edges, with to annular groove 16 that should combined hole 15, this fixed leg 32 is placed in this combined hole 15, and this fitting portion 33 runs through this head 11, be fixed in this moving part 22, and cooperate C shape button 35 to be fastened in the annular groove 34,16 of this fixed leg 32 and this combined hole 15.
This driving body 40, this driving body 40 is equipped with a circular tooth part 41 that is placed in this perforation 12 in side face, and these circular tooth part 41 central authorities run through and are provided with a connecting hole, and this connecting hole such as drawing are a plum blossom hole 42.
This keeper 50, this keeper 50 is established in the form of a ring, and be located in these 12 tops of boring a hole, this keeper 50 is provided with an annular groove 51, be embedded in for the annular groove 14,51 of this head 11 and this keeper 50 and be provided with C shape button 52, make the circular tooth part 41 top end faces that the end face of this keeper 50 can effectively spacing this driving body 40.
When spanner 10 is the bidirectional idling state, extremely shown in Figure 4 as Fig. 3, this moment, this driving lever 30 was parallel these spanners 10, and make this moving part 22 be positioned at this storage tank 13 middle positions relatively, and make the portion of balancing or cancel each other 213 of this gear block 21, the 214 neither walls that are resisted against storage tank 13, and two location divisions 222 of this moving part 22,223 neither two bearing surfaces 215 that are resisted against gear block 21,216, and the two ends of this springing part 23 are resisted against respectively in groove 221 and the locating slot 212, and make this spanner 10 can form two-way idling conditions, when being sleeved on the bolt (not shown) for the combined hole 15 of this driving body 40, rotate this spanner 10 this moment, this gear block 21 can compress this springing part 23, make these gear block 21 springing in this storage tank 13, to form idling conditions.
When spanner 10 is counterclockwise unidirectional use, just spanner 10 is when first operating position, as shown in Figure 5, the clicking section 31 of pulling this driving lever 30 is towards turning clockwise, make second bearing surface 216 of second location division, 223 these gear blocks 21 of pushing and pressing of this moving part 22, support portion 213 against wall and guide first of this gear block 21 to storage tank 13, and make this spanner 10 form the effect that can be counterclockwise unidirectional use, and cooperate second location division 223 of this moving part 22 effectively only to support for second bearing surface 216 of this gear block 21, to reach effective locating effect;
Must be noted that a end that this springing part 23 is located at locating slot 212 herein because of comparatively tightening, so spanner 10 oppositely during idle running, this springing part 23 is that unlikely breaking sold off shape, so that this spanner 10 reason part deformation and can't re-using not;
In addition, when clicking section 31 courts that pull this driving lever 30 are rotated counterclockwise, make first bearing surface 215 of first location division, 222 these gear blocks 21 of pushing and pressing of this moving part 22, support portion 214 against the time and guide second of this gear block 21 to storage tank 13 walls, this spanner 10 is to be clockwise unidirectional use, just spanner 10 is positioned at second operating position, so this inverse operation pattern be can think easily and, disclose so do not make accompanying drawing in addition.
Extremely shown in Figure 8 as Fig. 6, it is another preferred embodiment of the present invention, not not existing together of present embodiment and the foregoing description, mainly be less in combined hole 15 apertures of this spanner 10, and the periphery of combined hole 15 does not excavate, this driving lever 60 does not then have fixed leg, annular groove and C type and design such as buckles, and this driving lever 60 differs from the end in addition of clicking section 61, still extend and be provided with one and be enough to the fitting portion 62 that combines with moving part 22 draw-in grooves 224 towards combined hole 15, thus, this driving lever 60 is higher with respect to the raised position of this spanner 10, and the user can be provided the effect than this driving lever 60 of easy operating;
Moreover, another of present embodiment changes part, be to be this start assembly, wherein the springing part 25 of this start assembly 24 (also being a spring in the present embodiment) integral body is all laxly, and have preferable elasticity, and this springing part 25 is towards an end of locating slot 212, be to be sheathed on a stop part 26 in addition, and these stop part 26 1 ends be for cylinder 261 to be inserted in the springing part 25, the other end then is provided with butting section 262, and can be resisted against in this locating slot 212;
Mandatory declaration herein be; the cylinder 261 of this springing part 25 because of being sheathed on this stop part 26; therefore make that this springing part 25 is comparatively tight towards an end of locating slot 212; so no matter spanner 10 is under the state of counterclockwise unidirectional use or clockwise unidirectional use; during its idle running; neither this springing part 25 that causes produces the phenomenon of distortion, more therefore can protect the service life of this spanner 10.
As shown in Figure 9, it is an embodiment more of the present invention, and wherein roughly the structure with above-mentioned is identical for the whole kenel of this spanner 10, start assembly 20, driving lever 30, keeper 50, and the change part of present embodiment mainly is to be this driving body; Wherein, this driving body 70 axially is equipped with a joint portion, this joint portion is to be a muff joint 71, and this muff joint 71 is embedded with a steel ball 72 outwardly, and running through this driving body 70 is provided with one and takes off device 73 soon, taking off device 73 soon for this can break away from fast for the sleeve (not shown) that is linked to this muff joint 71, to increase the range of application of commutation driving rotary spanner 10.
