Description

The screwdriver that can be used for the nut assembling

Technical field

The utility model relates to a kind of screwdriver, particularly not only can be used for the screw assembling but also can be used for the screwdriver that nut assembles.

Background technology

Screwdriver is a kind of hardware ﹠ tools commonly used, is used to tighten or knockout screw.General screwdriver is made up of handle of a knife and knife bar, and according to the structure at knife bar tip, screwdriver is divided into yi word pattern and cross two kinds.At present, screwdriver only is used for the occasion of dismounting screw, and function is more single.But in practice, in the occasion of dismounting screw, often need the nut on the while assembling-disassembling bolt, the user must carry screwdriver and spanner simultaneously like this, not only takes up room, and carries and use all inconveniences.Particularly in some narrow spaces, spanner can not be stretched, and makes that the dismounting of nut is very difficult.

The utility model content

Technical problem to be solved in the utility model be to provide a kind of take up room little, carry and the screwdriver that can be used for the nut assembling easy to use.

The technical solution of the utility model is as follows: a kind of screwdriver that can be used for the nut assembling, comprise handle of a knife and knife bar, handle of a knife one end is fixedlyed connected with knife bar, and its key is: have groove on the end face of the described handle of a knife other end, the profile of this groove is a regular polygon.

Adopt above technical scheme, the tip of knife bar is a yi word pattern or cross, can be used for the dismounting of all kinds screw; Away from an end of knife bar the regular polygon groove is set at handle of a knife, this groove can be placed on the nut, is used for the dismounting of nut, is specially adapted to use in the narrow space.This shows that the utlity model has two kinds of functions, it is little not only to take up room, and carry and use all very convenient.

For the nut with dismounting adapts, the profile of described groove is regular hexagon or square.

In order to prevent to skid with nut, the degree of depth of described groove is 6-15mm.

In order to guarantee structural strength, prevent that handle of a knife from damaging that make things convenient for the user to hold simultaneously, described handle of a knife is an ironcasting, is set with antiskid glue sleeve in the outside of handle of a knife.

Beneficial effect: the utility model can either be used for the screw dismounting, can be used in nut assembling again, have reasonable in design, simple in structure, little, use and characteristics such as easy to carry take up room.
