This simple improvement will facilitate the work standard screwdriver, especially where it is difficult to get the tip into the slot of the screw or screws. This will require only two items: a small spiral spring, is wound directly on the rod of the screwdriver, and cut a metal tube. Its inner diameter should correspond to the maximum width of the tip. After putting on the rod tube is slightly deformed to form the fixing belt (see Fig.). A spring-loaded tube will perform the role of a conductor. Enough to catch it on the screw head and screwdriver tip will go in the slot.
