Abstract

The utility model relates to a combination wrench, which comprises a handle, a first clamping part and a second clamping part, wherein the first clamping part and the second clamping part are arranged on both sides of one end of the handle respectively; the first clamping part and the second clamping part form a first space for clamping a nut; a third clamping part is rotationally arranged on the handle; when the third clamping part is unscrewed, the third clamping part is positioned between the first clamping part and the second clamping part; a second space for clamping a nut is formed between the third clamping part and the second clamping part; meanwhile, a third space for clamping a nut is formed between the third clamping part and the second clamping part. According to the combination wrench in the scheme of the utility model, the third rotational clamping part is arranged between the first clamping part and the second clamping part; an original wrench which is only suitable for nuts of one specification is changed into a wrench which is suitable for nuts of two or three specifications. The combination wrench is simple in structure, and can be suitable for nuts of a plurality of specifications.

Description

A kind of combination wrench

Technical field

The utility model relates to a kind of improvement of spanner, particularly a kind of combination wrench of simple in structure, the nut that goes for plurality of specifications.

Background technology

Spanner, it is a kind of specific purpose tool, be used for tightening or unscrew nut or screw etc., because the specification of nut has a variety of, for easy to use, must support the use corresponding spanner, there are at present two kinds of common spanners, the first is the spanner that only adapts to a certain specification, and the second is the spanner of nut that is applicable to the width of certain limit; The first spanner structure simply, not general, the second spanner structure is complicated, cost is high; For this reason, we have developed combination wrench simple in structure, nut that go for plurality of specifications.

Utility model content

The utility model object is the combination wrench that a kind of simple in structure, nut of going for plurality of specifications is provided in order to overcome the deficiencies in the prior art.

For achieving the above object, the technical solution adopted in the utility model is: a kind of combination wrench, comprises handle, the first clamping part, the second clamping part; Described the first clamping part, the second clamping part are arranged on respectively the both sides of one end of handle; Described the first clamping part and the second clamping part form the first space of a clamping nut; Described the 3rd clamping part rotatably arranges on handle; When the 3rd clamping part screws out, described the 3rd retaining part is between described the first clamping part and the second clamping part; Between described the 3rd clamping part and the first clamping part, form the second space of a clamping nut, meanwhile, between described the 3rd clamping part and the second clamping part, form the 3rd space of a clamping nut.

Preferably, on described handle, be provided with strip hole, described the 3rd clamping part can precession strip hole in.

Preferably, when described the 3rd clamping part screws out, described the 3rd clamping part is not positioned at the center in the first space.

Preferably, when described the 3rd clamping part screws out, described the 3rd retaining part is in the center in the first space.

Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:

Combination wrench described in the utility model scheme by being provided with rotatably the 3rd clamping part between the first clamping part and the second clamping part; The spanner that originally can only be suitable for a kind of nut of specification has been become to the spanner of the nut of applicable 2 kinds or 3 kinds different sizes, the nut that the utility model is simple in structure, go for plurality of specifications.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

The stereogram of the first use state that accompanying drawing 1 is combination wrench described in the utility model;

Accompanying drawing 2 is the front view of accompanying drawing 1;

The front view of the second use state that accompanying drawing 3 is combination wrench described in the utility model;

Wherein: 1, handle; 2, the first clamping part; 3, the second clamping part; 4, the 3rd clamping part; 5, strip hole.

The specific embodiment

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

Accompanying drawing

1,2,3 is a kind of combination wrench described in the utility model, comprises handle 1, the first clamping part 2, the second clamping part 3; Described the first clamping part 2, the second clamping part 3 are separately positioned on the both sides of one end of handle 1; Described the first clamping part 2 and the second clamping part 3 form the first space of a clamping nut; Described the 3rd clamping part 4 rotatably arranges on handle 1; When the 3rd clamping part 4 screws out, described the 3rd clamping part 4 is between described the first clamping part 2 and the second clamping part 3; Between described the 3rd clamping part 4 and the first clamping part 2, form the second space of a clamping nut, meanwhile, between described the 3rd clamping part 4 and the second clamping part 3, form the 3rd space of a clamping nut; On described handle 1, be provided with strip hole 5, described the 3rd clamping part 4 can precession strip hole 5 in; When described the 3rd clamping part 4 screws out, described the 3rd clamping part 4 is not positioned at the center in the first space; Now, the nut of applicable three kinds of different sizes.

Certainly, when described the 3rd clamping part 4 screws out, described the 3rd clamping part 4 also can design the center that is positioned at the first space, now, can only be suitable for the nut of two kinds of different sizes.

Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
