Molinillo, characterized by comprising a support base of generally cylindrical shape and reduced height, open by its lower surface, on which is applied a flat disc, made of elastic material, which has a rigid central area, since it is interposed between discs metallic reinforcing elements, to which a rod is rigidly fixed, which is arranged in axial direction and crosses the upper surface of the base by a corresponding central hole, projecting to the outside and relating to a steering mechanism, by means of which it is possible to determine its axial movements of ascent and descent between two limit positions; all in such a way that, once the apparatus is placed on the supporting surface of interest, on which the expressed elastic disc rests in all its extension, it is enough to act on the indicated mechanism of government, determining the movement of ascent of the stem, for forcing the disk to assume a bulging position, creating between it and the support surface a vacuum chamber which, by a suction effect, determines a perfectly secure attachment of the apparatus to said surface.
