The longitudinal track has a first upper lateral segment and a second upper lateral segment, said first upper lateral segment having a ramp. An outer sleeve is fitted about the inner sleeve so as to be able to rotate with respect to the inner sleeve, said outer sleeve having an inner wall, an outer wall, and a helical track along the inner wall. A holder cup is fitted into the inner sleeve. The holder cup comprises a shell having an inner surface and an outer surface. A lug is attached to the outer surface and extends through the longitudinal track to engage the helical track. A bellows portion is located below the lug and comprises part of the shell of the holder cup, said bellows capable of occupying a first stretched position and a second contracted position.
