ABSTRACT:
A telescoping support post having a bell member slide mounted thereon to engage a mouth of a musical instrument in a manner to support the instrument. The inner telescoping member has a releasable holding member eccentrically mounted thereon. This holding member has a resilient finger frictionally engaging the inner surface of the outer telescoping member to insure proper locking and release action. In addition, the holding member has cooperating stop means to limit rotation between these two positions.
A similar device is operatably positioned between the bell member and the upper telescoping member so that the bell member can be adjusted vertically on the second telescoping member and held in any selected position.
