Claim:
An instrument stand with variable ground contact positions of its supporting pods, comprising: a standing post, which is mounted with a tool for a music player to use; two positioning rings mounted around the standing post, one of them being fixed and the other being able to slide within an appropriate interval relative to the former, wherein each positioning ring has a ring part whose outer side is symmetrically disposed with a plurality of supporting bases, each of which has a first connecting part, and a plurality of connecting elements that get fixed once their supporting angles relative to the supporting bases are adjusted, and a third connecting part extends from a second connecting part of each connecting element; and a plurality of supporting pods that change their supporting angles with the connecting elements, wherein the number of the supporting pods is the same as that of the supporting bases, a crank is provided between the two ends of each supporting pod, one end of the supporting pod has a supporting part, and each of the other end of the supporting pod and the end of the crank has a fourth connecting part corresponding to the third connecting part of the connecting element, and each supporting pod is controlled by the relative motion of the two positioning rings to expand and collapse.
