Abstract
A suction disc unit, especially a suction disc unit that can be adsorbed on a smooth surface to support a hung article, it comprises a pressing lid, a suction disc, a link and a pressing rod; wherein the pressing rod at least has a first eccentric protruding portion and a second eccentric protruding portion; when the pressing lid is pulled up to make abutment of the suction disc against the smooth surface by pushing of the pressing rod, the air in the gap between the suction disc and the smooth surface is removed as much as it can; when the pressing rod is pressed down, the pressing lid abuts against the periphery of the suction disc, and the central portion of the suction disc is pulled up tight, the air pressure in the gap is much lower than that of the atmosphere to thereby induce a strong suction force, and thereby to increase the bearing strength of the suction disc unit.
