Abstract
The invention relates to a spanner, in particular to a spanner for a single-way ratchet wheel. According to the technical scheme, the spanner for the single-way ratchet wheel comprises a handle body, a pressing spring, a hollow pin, a pawl and the ratchet wheel. The spanner is characterized in that the ratchet wheel is arranged at one end of the handle body, the ratchet wheel is meshed with a pawl gear, and a clamping spring is arranged on the ratchet wheel, so that the ratchet wheel rotates in a single direction.
Description
Technical field
The present invention relates to a kind of spanner, especially a kind of single direction ratchet spanner.
Background technology
In present tool world, rapid ratchet spanners more and more liked by people and uses it, and increasing people is constantly designing, inventing various new good spanner again.Such as fork spanner, adjustable wrench, speeder wrench etc.
Many tool manufacturer business, in order to promote the quality of rapid ratchet spanners, have devised different structures.Such as U.S.'s generation reaches instrument and just applies an iron sheet stamping, stage clip is disposed under straight line duty.Some Tianwan businessmans are with the diverse ways such as working of plastics, garden pin, steel ball and torsion spring, and object is also all to allow stage clip work better.But structure is all comparatively complicated, and processing cost is higher.
The present invention, in order to overcome above-mentioned defect, has carried out useful improvement.
Summary of the invention
The object of the invention is to solve above-mentioned deficiency of the prior art, done to improve, with a kind of structure of simple, reliable, low cost, provide a kind of single direction ratchet spanner.
Under the object of the invention is to allow stage clip and ratchet remain at good working order, thus keep high pulling torque and longer working life.
To achieve these goals, technical scheme of the present invention is: a kind of single direction ratchet spanner, comprise handle body, stage clip, hollow pins, ratchet, ratchet, it is characterized in that: described ratchet is installed on described handle body one end, described ratchet and ratchet gears meshing, described ratchet is provided with jump ring, described ratchet one-way is rotated.
Described ratchet to be installed in described handle body one end in circular hole.
Beneficial effect of the present invention: the present invention, with a kind of structure of simple, reliable, low cost, allows stage clip begin and under ratchet remains on good working order end, achieves good effect.Greatly improve the quality of this product! Through the test to product.The present invention reaches the highest level standard of pulling instrument soon, and torsion is apart from large, and working life is permanent, rotates, light and handy reliable again flexibly.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
Embodiments of the invention are with reference to shown in figure 1-5.
A kind of single direction ratchet spanner, comprises handle body, stage clip, hollow pins, ratchet, ratchet, it is characterized in that: described ratchet is installed on described handle body one end, and described ratchet and ratchet gears meshing, described ratchet is provided with jump ring, and described ratchet one-way is rotated.
Further, described ratchet is installed in described handle body one end in half-moon groove, and the ratchet of described ratchet is lower than the inner circle camber line of described half-moon groove.
Further, described half-moon groove side has the inclined hole installing described hollow pins, and utilizes stage clip to withstand hollow pins to enable pawl-and-gearing Elastic Meshing.
Further, described ratchet has the endoporus of 12 jiaos, and 72 ratchets of cylindrical are recessed straight-tooth.
Further, the tooth angle that described ratchet is is the one in 70 degree, 75 degree, 80 degree, 90 degree, 100 degree.
Further, the length specification scope of described spanner is 6m to 32mm.
Further, handle body selects steel alloy finish forge to form, and ratchet selects steel alloy cold forging to form.
This speeder wrench has six part compositions, and erection sequence is as follows:
(1) stage clip (2) is positioned in the aperture of hollow pins (3);
(2) hollow pins loading onto stage clip (2) is put into simultaneously the middle little inclined hole of half-moon groove of handle body (1);
(3) hollow pins is pushed down in the rear end of ratchet, by the interposition to half-moon groove, make the ratchet of ratchet lower than in the Nei Yuan hole line of spanner;
(4) put into ratchet (5) and jump ring (6) simultaneously;
(5) rotating ratchet (5) can hear smoothness, clear and melodious clearly demarcated tap-tap.
The course of work is as follows:
When external force F exerts a force to the direction of arrow, ratchet (4) will be subject to the extruding of semi-round groove garden cambered surface, and the outer straight-tooth on same ratchet (5) meshes together rotation tightly.12 jiaos of endoporus of ratchet (5) have just driven nut.When ratchet (5) band has rotated to certain angle with nut, handle can counter-rotation have been return.Ratchet (4) is due to the effect of stage clip, just be separated from together with the pointed tooth on ratchet (5), handle can do any rotation towards a direction, minimum angle is 5 degree, when handle remakes counter-rotation, ratchet (4) is by the effect of stage clip, and the outer straight-tooth again on same ratchet (5) has meshed together immediately.Be rotated further, ratchet (5) rotates with regard to driving workpiece, goes round and begins again.If need the operative orientation of lever change, spanner is stood up and uses.Unscrew or screw, just handyly can carry out operation rapidly continuously.
The above embodiment only have expressed one embodiment of the present invention, but therefore can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
