Scratching device in typewriters, characterized essentially by the fact of being constituted by three parts articulated with each other, a lower piece of U-shaped staple, which presents in a branch a screw displacing a clamping element against the edge of the machine housing, and as an integral part of the clip an open and elastic lug flange, provided with a clamping screw to lock the position of a central piece as a U-shaped lug, with a clamping screw between branches, which passes through a U-shaped opening, of a flat plate that forms part of the upper part, whose part is hollow for housing inside the tracer tool protruding at its ends, the hollow part comprising a longitudinal section at its front end as a clamp with a clamping screw so as to retain the position of the tool, the hollow part also comprising at its rear end a split lid in which cutting has the faculty of locating a step of a terminal part integral with the tracer tool to determine with them two positions of the tool, one forward of work and the other delayed or of rest.
