Abstract:
1. An adapter mount for attaching to a fitting tube having an inner surface comprising: an adapter tube having an outer circumferential surface; a first expandable ring placed on the outer circumferential surface of the adapter tube and comprising of elastic material for expanding and fitting to the inner surface of the fitting tube; a hollow adjustment ring configured to be threaded to the outer circumferential surface of the adapter tube to generate a rotational threading force; a compression ring for translating the rotational threading force from the adjustment ring to a longitudinal compressing displacement of the first expandable ring, causing an outer surface of the first expandable ring to fit to the inner surface of the fitting tube; a stop attached to the adapter tube for preventing the adjustment ring from separating from the adapter tube; a second expandable ring placed on the outer circumferential surface of the adapter tube and comprising of elastic material for expanding and fitting to the inner surface of the fitting tube; and a spacer placed on the outer circumferential surface of the adapter tube for keeping the first expandable ring and the second expandable ring apart at a predetermined distance.
