Abstract
An insulating screwdriver includes a handle, a drive shank having a first end mounted in the handle and a second end protruding outwardly from the handle, an insulating jacket mounted on the second end of the drive shank, and an identification insulating sleeve mounted between the second end of the drive shank and the insulating jacket. Thus, when the insulating jacket is worn out or broken due to friction or hit, the identification insulating sleeve is still located outside of the drive shank to provide a secondary insulating effect to the drive shank so as to protect the user when operating the drive shank.
