Adjustable support for glasses and cans which can support the weight of a plurality of containers of potable liquids, exploiting engagement with a vertical axis present in the vicinity; said adjustable support being further suitable for being quickly disassembled from said vertical axis, resulting in easy disassembly and facilitating transport and handling from one location to another; said adjustable support comprising: - at least a coupling clip, having a "C" shape, suitable for engaging with any vertical axis, thereby providing sufficient grip to support the entire adjustable support; said coupling clip comprising a rigid horizontal extension, suitable for facilitating installation of the entire adjustable support for glasses and cans, externally to said vertical axis; - at least a coating, installed internally to said coupling clip, suitable to increase the adherence of said clip on said vertical axis, limiting any possible downward sliding by the whole adjustable support installed on said coupling clip; - at least a vertical dorsal reinforcement, installed below said coupling clip, extending for at least 2 cm along said vertical axis, suitable to confer rigidity to the whole support limiting its vertical oscillations; said dorsal reinforcement being further suitable to increase the adherence of the whole support to the vertical axis; - at least a central pivot, having a tapered conical shape in which the thin upper tip is turned upward, suitable to engage within said rigid horizontal extension included in said coupling clip; said central pivot being suitable to accommodate a plurality of rings, each suitable to contain a different liquid container; - a plurality of rings suitable for being stacked on the upper tip of said central pivot, by means of a hole provided in the contour of said rings; each ring consequently being suitable for rotating around said central pivot, ensuring the support of several glasses and cans at the same time; - at least a LED light, included at the top of each ring, suitable to facilitate the recognition of the glasses assigned to specific persons, following the choice of a colour previously established; - at least a closing cap suitable for being engaged on said upper tip of the central pivot, once all the necessary rings have been stacked, for the purpose of closing the central pivot, preventing it from sliding downwards; - at least a disc, installed below said central pivot, suitable for constituting the base necessary to provide support for said central pivot on any surface, in the event that the constraint provided by the coupling clip is not sufficient; - at least an opening rod, one end of which is linked to the lower edge of said vertical dorsal reinforcement by means of a generic hinge, suitable to be disposed parallel to said rigid horizontal extension, in order to engage its free end with said disc, increasing the rigidity of the whole adjustable support subject of the invention. - at least a coupling clip, having a "C" shape, suitable for engaging with any vertical axis, thereby providing sufficient grip to support the entire adjustable support;
