Description

Be applicable to the clamp that narrow space and multi-angle are used
Technical field
The utility model relate to a kind of hand-operated tools field be used for fastening, connect, the clamp of dismounting or clamping tools, particularly relate to a kind of can with the more laborsaving and application of force more smoothness be applicable to the clamp that narrow space and multi-angle are used.It is to utilize to be provided with pivot structure and to be hubbed on the clamp piece, can reach the effect that is applicable to that narrow space and multi-angle are used, and become a kind of new design that quite has practicality and progressive, is suitable for the industrial circle wide popularization and application.
Background technology
See also shown in Figure 1, the existing clamp of commonly using (10), its structure mainly is to include a jaw (12) and two levers (14), when using this lever (14) in order to action, together with the time control jaw (12) folding, come the clamping object by this; Yet the jaw (12) of this clamp (10) is to be to be a straight line to arrange with lever (14), so wrist is to need bending operation in use, so cause the injury of user's wrist portion easily, be the injury of so-called carpal tunnel syndrome (carpaltunnel syndrome), and be unfavorable in narrow space or confined space, operating.
Recently, there is the clamp of new structure to come out again, extremely shown in Figure 4 as Fig. 2, the improvement part of this clamp is that jaw (15) is positioned at different axial locations with lever (16), when operation, wrist can with the forearm state that is in line, meet ergonomics, and existing conventional clamp structure helps more at narrow spatial operation.
Though yet the clamp of above-mentioned modified form can increase function of use, but its jaw (15) is to be set to remain in a fixing angle with lever (16), therefore only be suitable in particular environment, using, and can't quite be unsuitable for practical defective and still have in response to various narrow space.
Therefore, the applicant just designs the clamp structure that another kind is applicable to narrow space again at above defective, it is No. 474238 " being suitable for the clamp of narrow space " (seeing annex one bulletin text for details) of the novel patent announcement in Taiwan, this case mainly is the neck end that is provided with correspondence in the end pivot joint of lever, and make that this lever is rotated, and can be transformed to different directions, lever is rotated, and can be transformed into different operation forms, can effectively promote clamp applicability in the use, really has progressive, but when using, reality but finds also to have in its structure a fly in the ointment, cause this clamp in practical application, fail to reach best result of use, and its shortcoming can be summarized as follows:
1, the function of utilizing the lever of big length to rotate, cause rotational angle limited easily, that is to say when the user when use rotating lever, because general clamp is in order to reach comparatively labour-saving effect, its lever all can be set to long length, therefore when the rotation lever, then be easy to run into or to snap into other restricted articles, and have the influence that is subjected to the usage space limitation easily.
2, the pin-jointed structure of this case is arranged between lever and the pliers head, makes it in this articulated section fracture easily because pulling force is excessive.
3, the user is when using this clamp, easily because lever is a turntable, and when the application of force the effective application of force, or can't come the application of force, and cause the inconvenience in the use with fixed angle.
This shows that above-mentioned existing clamp still has many defectives, and demands urgently further being improved.
In order to solve the defective that existing clamp exists, relevant manufacturer there's no one who doesn't or isn't seeks the road that solves painstakingly, but does not see always that for a long time suitable design finished by development, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing clamp exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of founding a kind of clamp that narrow space and multi-angle are used that is applicable to of new structure, can improve general existing on the market conventional clamp structure, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
