This tool consists of a deformable plastic supporting base plate (1) bearing on its lower outer surface the stopper and abrasive materials, it further includes two upwards slanting interconnecting elements (2) in indeformable material or plates having a low deformability index, the lower end of these elements (2) being fastened to the transverse legs of the supporting base (1), two rotating cross journal (6) being secured to the upper end of the interconnecting elements (2), each journal (6) featuring at both ends threaded holes (9') as well as a longitudinal central boring (3', 4') with opposed threads, a screw (3, 4) half of which is left-threaded and the other half is right-threaded separated by a small control wheel (5), a guide (8) bearing the handgrips (10), provided with a central hole (11) through which the control wheel (5) is protruding, lateral slots (12) through which to fit the locking screws (9) into the borings (9') in both ends of the journals (6). The supporting base may be adjusted to the shape of the surface to be treated by changing the distance (L) between the journals (6) and the height (H1, H2) of the journals (6) above the supporting base (1).
