ABSTRACT:
A cup-holder stabilizer includes an upper holder portion adapted for the insertion of a cup or glass and formed with plural inner cylinders under the holder portion each formed with a valve inside the inner cylinder, a supporting base correspondingly formed with plural outer cylinders each reciprocatively engaged with each inner cylinder, and a plurality of suction cups each formed a central hole on the bottom portion of the suction cup, so that upon the gravitational retraction of the inner cylinders into the outer cylinders, the valves will seal all suction cup bottom holes so as to form vacuum for stably gripping the cup holder on a supporting surface and upon the raising of the cup with the upper holder, the valve will open the suction cup bottom hole to release vacuum for their easy removal.
