Detailed description of the invention
Consult shown in Fig. 3 to 8, the ratchet spanner of a kind of variable clamping dimension that the embodiment of the present invention provides, need first illustrate, this ratchet spanner of the present embodiment is act reversible ratcheting tool is example, but not as limit, this ratchet spanner also can be a kind of one-way ratchet wrench.This ratchet spanner is mainly made up of body 20, ratchet 30, adjustment part 40, two grip block 50 and a spring 60, wherein:
Described body 20, has the reversing unit 23 that shank 22 and that a head 21, connects this head 21 is located at this head 21; Because this reversing unit 23 is common components, and its to make flowing mode all identical with common, the also creation emphasis of non-invention, therefore for this component detailed construction with make flowing mode and no longer describe in detail.
Described ratchet 30, is hubbed at this head 21, and has the guiding cylindrical void 33 that pivot groove 32 and that a ratchet part 31, engaged with this reversing unit 23 has a groove bottom 321 is located at this pivot groove 32 groove bottom 321; In the present embodiment, the guiding cylindrical void 33 of this ratchet 30 has large footpath section 331 and the path section 332 extended by these section 331 both sides, large footpath, in addition, this ratchet 30 one end has one in order to abut against the ring portion 34 at head 21, and another end is buckled 35 by a C type and is hubbed on this head 21.
Described adjustment part 40, is hubbed at this pivot groove 32, and has a rotating part 41 and towards the adjustment tank 42 of this guiding cylindrical void 33, and this adjustment tank 42 has one and surrounds non-circular trough wall surface 421; In the present embodiment, this adjustment part 40 more comprises two in being relatively located at the first card recess 422 and two of this adjustment tank 42 trough wall surface 421 in the second card recess 423 being relatively located at this adjustment tank 42 trough wall surface 421, and the distance between this two first card recess 422 is greater than the distance between this 2 second card recess 423; In addition, this adjustment part 40 buckle 43 by C type, plain washer 44, wave spring washer 45, limit buckle 46 and be hubbed on the pivot groove 32 of this ratchet 30.
Described two grip blocks 50, this ratchet 30 and this adjustment part 40 is located in relative shape, and respectively have one and be positioned at clamping part 51, outside this head 21 and connect this clamping part 51 and be positioned at the neck 52, that this ratchet 30 guides cylindrical void 33 and connect this neck 52 and be positioned at the expansion portion 53 of this adjustment part 40 adjustment tank 42, this expansion portion 53 and with this adjustment tank 42 trough wall surface 421 blocking, in the present embodiment, this two grip block 50 has more one and to be convexly equipped in outside this expansion portion 53 and the card convex portion 54 be simultaneously fastened with this 2 first card recess 422 or the second card recess 423, and a recessed groove 55 inside each this expansion portion 53, and this grip block 50 is when assembling, the large footpath section 331 of this guiding cylindrical void 33 is first arranged in by its expansion portion 53, and make this neck 52 to should path section 332, subsequently by this grip block 50 towards this path section 332 direction displacement, the neck 52 of this grip block 50 is made to be set in this path section 332, namely this guiding cylindrical void 33 completes the assembling of this grip block 50 between this expansion portion 53 and this clamping part 51 simultaneously.
Described spring 60, between the expansion portion 53 being located at this two grip block 50, the card convex portion 54 making to be located at respectively this expansion portion 53 keeps blocking with this 2 first card recess 422 or the second card recess 423 being located at this adjustment tank 42 trough wall surface 421; In the present embodiment, this spring 60 is that a Compress Spring has two and is embedded end 61 at this groove 55 respectively.
The above is structure and the configuration explanation thereof of each main member of the embodiment of the present invention.Flowing mode is made and effect please refer to the following description as of the present invention.
Accordingly, the present invention at least has the adjustment of two kinds of clamping dimension.
The first clamping dimension: make described two grip blocks 50 by the pushing and pressing of this spring 60, and the card convex portion 54 being located at each described grip block 50 is fastened on be located at this 2 first card recess 422 of this adjustment part 40, now, the clamping part 51 of this two grip block 50, at a distance of the first clamp distance, is used and can be carried out lock to the screw tightening 71 of the first size and unload operation.
The second clamping dimension: consult shown in Fig. 8 to 11, the rotating part 41 of this adjustment part 40 of turn, the adjustment tank 42 of this adjustment part 40 is rotated thereupon, now, neck 52 due to described two grip blocks 50 is the guiding cylindrical voids 33 being limited to this ratchet 30, therefore, described two grip blocks 50 can along with trough wall surface 421 curve of this adjustment part 40 linearly close to each other or away from, when the card convex portion 54 of described two grip blocks 50 departs from the blocking of this 2 first card recess 422 and is fastened with this 2 second card recess 423, the clamping part 51 of this two grip block 50 is at a distance of the second clamp distance, and be greater than the distance between this 2 second card recess 423 due to the distance between this 2 first card recess 422, therefore, second this first clamp distance of clamp distance difference (being namely less than) that the clamping part 51 of this two grip block 50 produces, and lock can be carried out to the screw tightening 72 of the second size and unload operation.
Accordingly, the present invention is by the rotating part 41 of this adjustment part 40 of turn, to adjust the relative position of this two grip block 50 expansion portion 53 in this adjustment part 40 adjustment tank 42, allow this two grip block 50 neck 52 along this guiding cylindrical void 33 displacement simultaneously, to change the distance between this two clamping part 51, and the lock that can be used as multiple different size screw tightening 71,72 unloads the use of operation, use the object reaching and promote this ratchet spanner applicability.
In sum, the various embodiments described above and diagram are only preferred embodiment of the present invention, when can not with the scope of restriction the invention process, the equalization change namely generally done according to the present patent application the scope of the claims with modify, all should remain within the scope of the patent.
