Abstract
Perfected screwdriver, characterized in that it is essentially constituted by a handle in which there is inserted a cylindrical shank, terminated by a flat angular head, in which there is interposed a sliding bushing capable of being displaced from the handle itself to drive a plate that it is partially inserted in a longitudinal groove made in the cylindrical shank, to which it is held by means of a transverse axis, and whose plate that at its front end ends in a point, makes a tightening by expansion against the inner walls of cutting the head of the screw into which the screwdriver's mouth is inserted.
