Abstract
A new screwdriver, characterized in that it consists essentially of a screwdriver rod coupled to a cylindrical extension that has the handle, said rod having, near its head, a channel that surrounds it and in which a washer is placed, arranging the wrapped rod in a spring that abuts on said washer and that is pushed by a bushing, and the whole assembly being contained in a tube shaped at one end and internally threaded on the other, in which a nut is provided that stops with the cylindrical projection of the handle of the screwdriver; in such a way that when exerting pressure on said nut, the tube descends outside and the cap and the tip of the screwdriver are hidden inside, at that moment entering the mouth of the tube, the head of the screw, so that when leaving of pressing on the nut, the inner spring is free and pushes the tube towards the handle, leaving the tip of the screwdriver that fits in the head of the screw, which is thus retained by the constant pressure exerted by said spring.
