Abstract

The utility model relates to a continuously adjustable ratchet wrench, which comprises a wrench handle. The two ends of the wrench handle are provided with a ratchet device in a hollow pipe shape, and the two opening ends of the hollow pipes are both provided with two sleeve openings. The sizes of the sleeve openings of the ratchet devices differ from each other and respectively correspond to different nut or bolt models. The wrench handle is provided with a sleeve, and the model of the sleeve matches with the model of the sleeve openings. The utility model has the advantages of simple structure and convenient operation, and can adapt to nuts or bolts of various models, thereby preventing the application of solid wrenches of different models. Moreover, the utility model can be used for continuous twisting. Therefore, the utility model not only has wide range of application, but also has high efficiency of use.

Description

Continuous adjustable ratchet wrench

Technical field

The utility model relates to a kind of hardware ﹠ tools, particularly a kind of continuous adjustable ratchet wrench.

Background technology

Irommongery is that both tradition presented the industry in generation again, and hardware is of many uses, and in the past, people are its Xiao Jin, such as nail, scissors, spanner, cutter.Nowadays the hardware that these are slight has developed into the big industry with world's influence power.And spanner is as an important part wherein, bringing into play the effect that can not despise in the production of modern society and life.At present more common spanner is gone up by society has following several: 1. fork spanner, the one or both ends of this spanner are shaped on the opening of fixed dimension, in order to the nut or the bolt of twisting certain size, the fixed size at the two ends of this type of spanner, therefore, when the nut of facing different model or bolt, need to use simultaneously spanner with different model.2. double offset ring spanner, these spanner two ends have the working end in band hexagon ring or 12 jiaos of holes, are applicable to that working space is narrow and small, can not use the occasion of common wrench.3. adjustable wrench, this type of width across flat can be regulated in the certain size scope, can twist the bolt or the nut of different size.4. box spanner, it is by the sleeve in a plurality of band hexagon rings or 12 jiaos of holes and be furnished with multiple annexes such as handle, extension bar and form, and is specially adapted to twist status very narrow and small or cave in the very bolt or the nut of depths.5. ratchet spanner, manual screw degree of tightness instrument, single head, many specifications of double end activity handle ratchet (fixing hole) double offset ring spanner.More above listed several spanner commonly used can not twist when fork spanner and double offset ring spanner work continuously and model is fixed, and size can not be transferred, and can only reverse the nuts and bolt of certain size; And adjustable wrench though box spanner can be adjusted the model size, is appointed so and can not be twisted continuously when work.Ratchet spanner has then solved the common drawback of several spanners in front---can not twist continuously.But it still has only fixedly model, can not realize changing between different model.

Summary of the invention

The purpose of this utility model provides a kind of continuous adjustable ratchet wrench with regard to being to overcome the deficiency of above-mentioned prior art, and this spanner can either realize often having the conversion between the model, can twist continuously when work again.

Realize that the technical scheme that the utility model purpose adopts is: a kind of continuous adjustable ratchet wrench, comprise pinch bar, the two ends of pinch bar are provided with ratchet device, and wherein ratchet device is a hollow tubular, and two openends of hollow tube all are equipped with two running-ons.Each cuff size of ratchet device is different, corresponding different respectively nut or bolt model.Have sleeve on the handle of spanner, sleeve model and running-on coupling.

The cuff size of the ratchet device openend at handle two ends differs, and can mate the nut of four kinds of different models or bolt.Running-on places the sleeve of model correspondence, if need spanner to twist the nut or the bolt of a certain model, then only needs the running-on of this model is taken out, and twists on the ratchet device in the corresponding running-on.This spanner is the running-on of four kinds of models simultaneously.The utility model can be provided with different running-on models according to different needs, can realize the running-on of 4 different models on a spanner.

The utility model is simple in structure, and is easy to operate, can adapt to the nut or the bolt of multiple model, avoids using the fork spanner of multiple model, and can twist continuously.Not only applied widely, and the service efficiency height.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Accompanying drawing is a front view of the present utility model.

Among the figure, 1. handle, 2. running-on, 3. ratchet device, 4. sleeve, 5. sleeve, 6. running-on, 7. ratchet device.

The specific embodiment

Embodiment

The front view of the continuous adjustable ratchet wrench of the utility model comprises pinch bar 1 as shown in drawings, and the two ends of pinch bar 1 are provided with

ratchet device

3,7, and wherein ratchet device is a hollow tubular, and two openends of hollow tube all are equipped with two running-ons 2,6.Each cuff size of ratchet device is different, corresponding different respectively nut or bolt model.Have

sleeve

4,5 on the handle of spanner, sleeve model and running-on coupling.

The cuff size of the ratchet device openend at handle two ends differs, and can mate the nut of four kinds of different models or bolt.Running-on places the sleeve of model correspondence, if need spanner to twist the nut or the bolt of a certain model, then only needs the running-on of this model is taken out, and twists on the ratchet device in the corresponding running-on.This spanner is the running-on of four kinds of models simultaneously.

In the present embodiment, running-on 2 and sleeve 4 couplings, running-on 6 and sleeve 5 couplings.In like manner, at the another side of spanner, running-on also mates with corresponding sleeve.When use needs the running-on of model, only need to take out this running-on, be installed on the corresponding end of ratchet device, can use.

Claims

1. a continuous adjustable ratchet wrench comprises pinch bar, it is characterized in that: the two ends of pinch bar are provided with ratchet device.

2. continuous adjustable ratchet wrench according to claim 1 is characterized in that: ratchet device is a hollow tubular, and two openends of hollow tube all are equipped with two running-ons.

3. continuous adjustable ratchet wrench according to claim 2 is characterized in that: each cuff size of ratchet device is different, corresponding different respectively nut or bolt model.
