Description

The combined type screwdriver

Technical field

The utility model relates to screwdriver, specifically is a kind of combined type screwdriver.

Background technology

Existing combined type screwdriver is roughly between screwdriver bit and batch bar or batch bar and the handle and is removable the connection, form different screwdrivers by changing screwdriver bit or criticizing bar, though this class combined type screwdriver scope of application is wide, practical, be inconvenient to be used for the occasion of the big or small moment of needs.Prior art is in order to address the above problem, there is a kind of combined bolt to criticize, its structure comprises batch bar and the handle that is fixed with one, sleeve, these sleeve central authorities have the cross section and are polygonal jack, and described handle also has corresponding polygonal cross-section, and can with and overlap the inserting one, the screwdriver of this structure is because handle comes embedded the cooperation with sleeve by polygonal cross-section, but also there is following shortcoming: if polygonal limit is very few, though its circumferential spacing property is good, user's gripping sense is poor, if polygonal limit is too much, though user's gripping is felt, its circumferential spacing property is poor.

The utility model content

The technical problems to be solved in the utility model is, provide a kind of grip sense well, combined type screwdriver that axial limiting is good.

The technical solution of the utility model is, a kind of combined type screwdriver with following structure is provided, comprise batch bar, handle, sleeve, described batch of bar is connected with handle is removable, described handle is connected with sleeve is removable, be characterized in that the outside of described handle is the external tooth wheel shape, described sleeve and handle junction are corresponding internal tooth wheel shape.

After adopting above structure, the utility model compared with prior art, have the following advantages: because the outside of described handle is the external tooth wheel shape, described sleeve and handle junction are corresponding internal tooth wheel shape, like this when not having the hilt cover, user's hand directly is held on the handle, and the external tooth wheel shape on the handle is felt user's gripping; After loading onto sleeve, cooperate by the concavo-convex of inside and outside gear shape between handle and the sleeve, make its axial limiting good, guaranteed that handle loads onto behind the sleeve in use, can not make sleeve and Handle axis to relatively rotating.
