Abstract
A multi-leg stand mainly includes a vertical main tube and a tripod structure connected to a lower end of the main tube. The tripod structure includes an inner tube around which a locking element and three unions are sequentially mounted from top to bottom. Three legs are separately connected at inner ends to the three unions. When the locking element engages with the first union at a first locking position, the three legs are folded to locate at the same side of the main tube, and when the locking element engages with the first union at a second locking position, the three legs are equally angularly spaced and radially extended. And, when the locking element is in a releasing position on the inner tube, the three unions may be freely turned in one direction with only one hand to quickly and accurately move into the folded or the spaced position.
