Abstract

The invention discloses a flexible wrench which comprises a wrench body and a driving end. A screwing sleeve hole is formed in the working end of the driving end, an inserting groove is formed in one end of the wrench body, due to the fact the non-working end of the driving end is inserted into the inserting groove, the driving end and the wrench body are installed together, a hanging ring is arranged at the other end of the wrench body, a hanging hole is formed in the non-working end of the driving end, and therefore when not used, the driving end is hung on the hanging ring of the wrench body through the hanging hole. The flexible wrench has the advantages that the wrench body and the driving end are of an independent structure, a plurality of driving ends can be assembled according to requirements so that a proper driving end can replace an improper driving end at any time in work, the wrench is flexible and convenient to use, and cost is reduced while the weight of the tool is reduced.

Description

A spanner alive

Technical field

The present invention relates to a kind of spanner, relate in particular to the work spanner that a kind of driving end can be changed at any time.

Background technology

Spanner be a kind of be used to tighten or looser a bolt, the instrument of nut, normally an end is provided with the trepanning of fixed dimension or shape.But because in the practical application, bolt, nut size, shape specification are various, often one-stop operation will be run into multiple size, and this just need join individual a plurality of spanners.And spanner generally all is metallic article, and Heavy Weight carries inconvenience, and need make different spanners, the cost height at bolt, the nut of different size.

Summary of the invention

Goal of the invention: goal of the invention of the present invention provides a kind of work spanner, can be equipped with a plurality of driving ends as required, changes suitable driving end at any time when satisfying work, and is flexible and convenient to use, and the weight that has alleviated instrument has also reduced cost simultaneously.

Technical scheme: a work of the present invention spanner, comprise wrench body and driving end, the working end of described driving end is provided with screws trepanning, one end of described wrench body is provided with slot, described driving end is installed together by non-operative end being inserted described slot and wrench body, the other end of wrench body is provided with link, and the driving end non-operative end is provided with hanging hole, does not hang on the link of wrench body by described hanging hole when driving end is not worked.

In order to guarantee to have certain fastness in the driving end non-operative end insertion wrench body slot, described driving end non-operative end is inserted the thickness of wrench body socket portion and is thickeied gradually.

Beneficial effect: the present invention compares with existing spanner, its distinguishing feature is that wrench body and driving end are absolute construction, can be equipped with a plurality of driving ends as required and change suitable driving end at any time when satisfying work, flexible and convenient to use, the weight that has alleviated instrument has also reduced cost simultaneously.

The specific embodiment

The present invention is described further below in conjunction with specific embodiment.

As shown in Figures 1 to 4, a work of the present invention spanner comprises wrench body 1 and driving end 2.The working end of driving end 2 is provided with screws trepanning.One end of wrench body 1 is provided with slot 11.Driving end is provided with link 12 by non-operative end being inserted described slot 11 with the other end that wrench body 1 is installed together wrench body 1, and driving end 2 non-operative end are provided with hanging hole 21, do not hang on the link 12 of wrench body 1 by hanging hole 21 when driving end 2 is not worked.Driving end 2 non-operative end are inserted the thickness of wrench body 1 slot 11 parts and are thickeied gradually, to guarantee having certain firmness in driving end 2 non-operative end insertion wrench body 1 slot 11.

Can be equipped with a plurality of driving ends 2 as required, the trepanning of screwing of each driving end 2 working end is different size, different size, as undersized hexagonal trepanning, large-sized hexagonal trepanning, undersized five jiaos of trepannings etc., hang over all driving ends 2 on the link 12 of wrench body 1 by hanging hole 21 when not using, select suitable driving end 2 to be installed on the wrench body 1 during work as required, use flexible.Because wrench body 1 of a plurality of driving end 2 common uses, the weight that has alleviated instrument has also reduced cost simultaneously.
