The utility model content
The utility model provides a kind of small-bore hexagonal short sleeve, and it mainly is that to solve the structure of existing in prior technology screwdriver comparatively complicated, and production cost is higher, is not suitable for the technical problem of general family, enterprise etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of small-bore hexagonal short sleeve of the utility model; Comprise upper bush body and lower sleeve body that integral body is processed, be provided with square hole in the described upper bush body, the edge of square hole is provided with deep-slotted chip breaker; Be provided with hexagon ring in the lower sleeve body; The edge of hexagon ring is provided with the arc lower groove, is provided with changeover portion between upper bush body and the lower sleeve body, and the bore of lower sleeve body is less than the bore of upper bush body.Can insert the handle of a knife of various tool in the square hole of upper bush body, last deep-slotted chip breaker can limit handle of a knife and can not rotate.Can insert various cutterheads in the hexagon ring of lower sleeve body, the arc lower groove can limit cutterhead and can not rotate.Can make up different handle of a knifes and cutterhead through short sleeve like this, the scope of application is wider.The bore of lower sleeve body makes the handle place can apply bigger power less than the bore of upper bush body, and cutterhead is can the place of working more smooth and easy.Upper bush body and lower sleeve body integral body are processed.
As preferably, have annular groove on the inwall of described upper bush body.Can be provided with place kick on the handle of a knife, place kick can be connected in the annular groove, prevents that handle of a knife from deviating from short sleeve in use.
