Description

Difunctional screwdriver

Technical field

The utility model relates to a kind of screwdriver, particularly has the screwdriver of two kinds of functions.

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.

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 difunctional screwdriver easy to use.
