Abstract
The invention discloses a novel universal wrench, belonging to the technical field of wrenches. The novel universal wrench comprises a wrench body, a trepanning, a sleeve, a square hole, a connecting end, a first assembling column, a second assembling column and a third assembling column, wherein the trepanning is arranged in the wrench body, the square hole is arranged in an assembling end of the sleeve, the first and second assembling columns are arranged at two ends of the connecting rod, and the third assembling column is arranged at the end part of the first assembling column. According to the novel universal wrench, the problem that the traditional connecting piece is not universally used by square holes of different specifications is solved, a special type connecting rod is arranged, the first and second assembling columns with the same specification are arranged at two ends of the connecting rod, and the third assembling column with reduced specification is arranged at the end part of the first assembling column in a convex manner; and the large and small specifications of the assembling ends of the sleeve can be changed by utilizing change-over assembling of the connecting rod.
Description
Technical field
The present invention is a kind of novel universal spanner specifically, belongs to the spanner technical field.
Background technology
General sleeve all has the protruding axle of a square with the dog point of spanner, so as to insert group in the set square hole of sleeve, and then make spanner reach purpose with moving sleeve, common spanner, bolt, the nut that will uncage as people are when being arranged in depression, deep trouth environment, general spanner can't adopt the mode of direct combined sleeve to reach purpose, and then must reach the purpose of extending the protruding shaft length of this spanner by some connectors this moment; The at present design of this kind connector, its two ends specification is normally identical, but there are the different of metric system and British system specification in the sleeve that is commonly used at present, so that the size of its square hole is difference to some extent, so, cause this connector can't reach with singular association spare the purpose of the square hole that is common to public affairs, sleeve made in Great Britain, also therefore, the indispensable number of tools that causes the user must increase and empty gain in weight burden has improved cost simultaneously.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides a kind of novel universal spanner, solves the problem that traditional connector can't be common to the square hole of different size sleeve.
To achieve these goals, the technical solution used in the present invention is: a kind of novel universal spanner, comprise wrench body, be located at the trepanning on the wrench body, sleeve, and the square hole that is located at the sleeve connection terminal comprise connecting rod, be located at the first winding post and the second winding post at connecting rod two ends, be located at the 3rd winding post of the first winding column end.
Wherein, the first winding post is identical with the second winding post specification; The end of the first winding post more convexes with the 3rd winding post that specification is dwindled; The connecting rod section is circular or polygon or square; When connecting rod was square, the first winding post, the second winding post presented concordant the linking with connecting rod; First connects that post, second connects post, the 3rd winding post is the square cylinder, corresponding with the square hole of the connection terminal of sleeve.
The invention has the beneficial effects as follows: solve the problem that traditional connector can't be common to the square hole of different size sleeve; The present invention is provided with the connecting rod of specific pattern, and these connecting rod two ends have first, second identical winding post of specification, and wherein the end of a winding post more convexes with the 3rd winding post person that a specification is dwindled; Can utilize the commutation winding of this connecting rod, the large and small specification of convertible its sleeve connection terminal.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention
Among the figure: 1, sleeve, 10, connecting rod, the 11, first winding post, the 12, second winding post, the 13, the 3rd winding post, 20, wrench body, 21, trepanning.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of novel universal spanner, comprise wrench body 20, be located at the trepanning 21 on the wrench body 20, sleeve 1, and the square hole 02 that is located at sleeve 01 connection terminal comprise connecting rod 10, be located at the first winding post 11 and the second winding post 12 at connecting rod 10 two ends, be located at the 3rd winding post 13 of the first winding post 11 ends; The first winding post 11 is identical with the second winding post 12 specifications; The end of the first winding post more convexes with the 3rd winding post 13 that specification is dwindled; Connecting rod 10 sections are circular or polygon or square; When connecting rod 10 was square, the first winding post 11, the second winding post 12 presented concordant the linking with connecting rod 10; First connects that post 11, second connects post 12, the 3rd winding post 13 is the square cylinder, corresponding with the square hole of the connection terminal of sleeve.
The cubic hole 2 of described sleeve 1 is corresponding with the spanner 20 with trepanning 21, the present invention includes connecting rod 10, its two ends have the first identical winding post 11 of specification and the second winding post 12, and wherein the end of a winding post more convexes with the 3rd winding post 13 that a specification is dwindled; Can utilize the commutation winding of connecting rod 10, the large and small specification state of its sleeve connection terminal of conversion, since the first winding post 11, the second winding post 12, the 3rd winding post 13 all can with cubic hole 2 windings of sleeve 1, therefore be alleged sleeve connection terminal, and this moment, another end on the other side was the spanner connection terminal.
