ABSTRACT:
An instrument stand with variable ground contact positions of its supporting pods is disclosed. It has a standing post mounted with two positioning rings. One of them is fixed, and the other can slide relative to the former. The positioning rings have several supporting bases and several connecting elements that fix with the supporting bases after angle adjustment. The supporting pods are locked on the two positioning rings. Each supporting pod is controlled by the relative motion of the two positioning rings to expand and collapse. The ground contact positions of the supporting pods of the invention are thus variable.
