Abstract
The utility model relates to a spanner, and particularly relates to a one-way rapid ratchet spanner. The one-way rapid ratchet spanner comprises a handle body, a pressure spring, a hollow pin, a pawl and a ratchet wheel. The one-way rapid ratchet spanner is characterized in that the ratchet wheel is arranged at one end of the handle body, and is meshed with a pawl gear; and a clamping spring is arranged on the ratchet wheel so that the ratchet wheel can rotate in a one-way way.
Description
Technical field
The utility model relates to a kind of spanner, especially a kind of unidirectional rapid ratchet spanners.
Background technology
In the present tool world, rapid ratchet spanners is more and more liked by people and use it, increasing people is constantly designing, is inventing various new good spanners again.Such as fork spanner, adjustable wrench, speeder wrench etc.
Many instruments manufacturer has all designed different structures in order to promote the quality of rapid ratchet spanners.For example U.S.'s generation reaches instrument and has just used an iron sheet and rush part, stage clip is disposed under the straight line duty.Some Tianwan businessmans use the diverse ways such as working of plastics, garden pin, steel ball and torsion spring, and purpose also all is in order to allow stage clip work better.But structure is all comparatively complicated, and processing cost is higher.
The utility model has carried out useful improvement in order to overcome defects.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, done to improve, with a kind of simply, reliably, structure cheaply, a kind of unidirectional rapid ratchet spanners is provided.
The purpose of this utility model is to allow stage clip and ratchet remain under the good working order, thereby keeps high pulling torque and long working life.
To achieve these goals, the technical solution of the utility model is: a kind of unidirectional rapid ratchet spanners, 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 the engagement of ratchet gear, on the described ratchet jump ring is installed, described ratchet one-way is rotated.
Described ratchet is installed in the interior circular hole of described handle body one end.
The beneficial effects of the utility model: the utility model with a kind of simply, reliably, structure cheaply, allow stage clip begin and ratchet remains under the good working order end, obtained good effect.Greatly promoted the quality of this product! Through the test to product.The utility model reaches the highest level standard of pulling soon instrument, and torsion is apart from large, and working life is permanent, rotation, lightly reliable again flexibly.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment of the present utility model is with reference to shown in the figure 1-5.
A kind of unidirectional rapid ratchet spanners 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 the engagement of ratchet gear are equipped with jump ring on the described ratchet, and described ratchet one-way is rotated.
Further, described ratchet is installed in described handle body one end in the half-moon groove, and the ratchet of described ratchet is lower than the interior circular arc line of described half-moon groove.
Further, described half-moon groove one side has the inclined hole that described hollow pins is installed, and utilizes stage clip to withstand hollow pins to make the pawl-and-gearing can Elastic Meshing.
Further, described ratchet has 12 jiaos endoporus, and 72 ratchets of cylindrical are recessed straight-tooth.
Further, the described ratchet tooth angle that is is a kind of in 70 degree, 75 degree, 80 degree, 90 degree, 100 degree.
Further, the length specification scope of described spanner is that 6m is to 32mm.
Further, the handle body selects the steel alloy finish forge to form, and ratchet selects the steel alloy cold forging to form.
This speeder wrench has six parts and forms, and erection sequence is as follows:
(1) stage clip (2) is positioned in the aperture of hollow pins (3);
(2) hollow pins of loading onto stage clip (2) is put into little inclined hole in the middle of the half-moon groove of handle body (1) simultaneously;
(3) hollow pins is pushed down in the rear end of ratchet, the interposition by to half-moon groove is lower than in the Nei Yuan hole line of spanner the ratchet of ratchet;
(4) put into simultaneously ratchet (5) and jump ring (6);
(5) rotating ratchet (5) can be heard smoothness, clear and melodious clearly demarcated tap-tap.
The course of work is as follows:
As external force F during to the direction of arrow application of force, ratchet (4) will be subject to the extruding of semi-round groove garden cambered surface, and the outer straight-tooth on the 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, but the handle counter-rotation is return.Ratchet (4) is because the effect of stage clip, just be separated from together with the pointed tooth on the ratchet (5), handle can be done any rotation towards a direction, minimum angle is 5 degree, when handle remakes counter-rotation, ratchet (4) is subjected to the effect of stage clip, and the outer straight-tooth on the same ratchet (5) has meshed together immediately again.Be rotated further, ratchet (5) just drives workpiece and is rotated, and goes round and begins again.If need the operative orientation of lever change, spanner stood up use get final product.Unscrew or screw, just can handyly carry out continuously rapidly operation.
The above embodiment has only been expressed a kind of embodiment of the present utility model, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
