Abstract
A slotted screwdriver with saw teeth on tool bit side edge is composed of a shank (1) and a cutter bar (2) on the structure, and the slotted screwdriver is characterized in that tool bit side edge saw teeth (3) are arranged on the side edge of the tool bit of the cutter bar (2), the tool bit side edge saw teeth (3) are arranged on the side edge of the tool bit of the cutter bar (2), so that when a screw groove is broken during the screw twisting process caused by too small hardness of a screw cap material or a too shallow screw groove, the tool bit side edge saw teeth (3) can be used for cutting back and forth along the trace of the screw groove to form a deeper screw groove so as to conveniently continue to utilize the slotted screwdriver provided by the utility model to unscrew or screw down the screw, namely, backing out or screwing in the screw, and the slotted screwdriver creates a condition of solving the problem that the screw with broken screw groove is difficult to be unscrewed or screwed down.
Description
Technical field
The utility model relates to the screwdriver structure technology.
Background technology
At present, people are when using screwdriver to unscrew or screwing screw, if the screw cap material hardness is too small or screw slots are shallow excessively; Then be easy to twist bad screw slots; In case it is bad that screw slots are twisted, with the problem that causes difficult back-out of screw or precession, when especially unscrewing screw; If it is bad that screw slots are twisted, even the problem that might cause this screw to screw out.
Summary of the invention
The purpose of the utility model is to propose a kind of screwdriver structure that addresses the above problem.
The key of the utility model is: structurally be made up of: handle of a knife and knife bar.
