Abstract
The utility model discloses a free wrench belonging to a wrench tool technical field including a wrench body. The containing space at the head of the wrench body is engagingly provided with a circlip, a pawl, a spring and a ratchet wheel, wherein the ratchet wheel comprises a ratchet wheel body and a sleeve gasket, the sleeve gasket is a loop which is periphery provided with a hollow toroid groove, and the sleeve gasket is engagingly covered at one side of the wrench body. As prior ratchet wheel components which are of integrated construction are dissociated into the ratchet wheel body and the sleeve gasket, the free wrench can avoid that one side of the hollow toroid groove of the prior ratchet wheel components is high while the other side is low which is of difficult manufacture. As the processing of the ratchet wheel body and the sleeve gasket is relatively easy, the processing and production efficiency of the free wrench is largely improved and the cost is reduced. Meanwhile, the original function of the free wrench is not affected.
Description
Technical field
The utility model belongs to the Wrench technical field, is specifically related to a kind of ratchet spanner.
Background technology
Ratchet spanner is one of instrument common in the present Wrench.Existing ratchet spanner generally comprises a wrench body, is equipped with jump ring, ratchet, spring and ratchet in the accommodation space by this wrench body head and constitutes.Referring to used ratchet in the existing ratchet spanner shown in Figure 1, this ratchet is structure as a whole, and periphery one side of this ratchet is provided with concave ring groove 2; Yet,, greatly increased the difficulty of processing of these parts, thereby the production efficiency of ratchet spanner reduces, and production cost improves by the radius of the outer trough edge 3 of this concave ring groove 2 radius greater than interior trough rim 1.
The utility model content
For overcoming problems of the prior art, the utility model aims to provide a kind of technical scheme of ratchet spanner, this ratchet spanner can be enhanced productivity, reduce production costs by improving used ratchet part, does not also influence the original function of ratchet spanner simultaneously.
Described ratchet spanner, comprise a wrench body, be equipped with jump ring, ratchet, spring and ratchet in the accommodation space of this wrench body head, wherein, described ratchet is made of ratchet main body and spacer, this spacer is the annulus that a periphery is provided with concave ring groove, and this spacer engage sleeves is located at a side of ratchet main body.
Described ratchet spanner, wherein, the other end of wrench body is provided with open-end wrench.
Described ratchet spanner, wherein, the other end of wrench body is provided with ratchet spanner.
Described ratchet spanner, be decomposed into by ratchet main body and spacer by ratchet part and constitute original integrative-structure, avoided the high low difficulty of processing that causes on one side in one side of the concave ring groove on original ratchet part, again because ratchet main body and spacer component processing are relatively easy, make this ratchet spanner processing efficient improve greatly, also reduce production costs, also do not influence the original function of ratchet spanner simultaneously.
Description of drawings
Fig. 1 is the structural representation of existing ratchet part.
Fig. 2 is the decomposition texture schematic diagram of ratchet spanner described in the utility model.
Fig. 3 is a ratchet spanner head construction cutaway view described in the utility model.
Specific embodiment
Now, further specify specific embodiment of the utility model in conjunction with Figure of description.
Referring to Fig. 2, ratchet spanner shown in Figure 3, comprise a wrench body 5, be equipped with jump ring 9, ratchet 11, spring 10 and ratchet in the accommodation space 6 of these wrench body 5 heads, wherein, described ratchet is made of ratchet main body 7 and spacer 8, this spacer 8 is the annulus that a periphery is provided with concave ring groove 81, and these spacer 8 engage sleeves are located at a side of ratchet main body 7; The jump ring 9 of C type is fastened between concave ring groove 81 and the accommodation space 6, plays the effect that fixed ratchet wheel does not skid off accommodation space, thereby ratchet can be fixed in the accommodation space 6 rotationally; The other end of wrench body 5 is provided with open-end wrench 4, and the ratchet spanner of above-mentioned same spline structure, different size specification perhaps is set.
