Abstract: An assembly for holding cup-shaped objects. The assembly includes an outer retaining tube, an inner retaining tube having a diameter smaller than that of the outer retaining tube, wherein the inner retaining tube engages the outer retaining tube in a telescoping manner, a spring positioned inside the tubes, a piston positioned at a first end of the spring, and a head assembly that engages the outer retaining tube, the head assembly containing a ring assembly operably connected to a plurality of flippers that, in response to rotation of the ring assembly, provide a varying diameter within the head assembly. The telescoping feature provides for adjustable length of the assembly while the varying diameter of the head assembly provides for cups of various diameters to be used in the assembly.
