The invention consists of two rigid parts (aI-a2), which are pivoted and are able to adjust and lock the angle formed (screw knob -b-); a set of sliders (c) with adjustable extension (d), present also at the two lateral ends of the rigid scales: one flexible scale (f) with an undercut in which sliding blocks can slide, which are then joined with an articulated joint (e) to the extensions (d). The various openings of the angle between the two rigid scales and the variety of co-ordinate positions taken up by the sliders and the extensions allow the flexible scale to be made to adhere to a discrete range of curves.
