A connector structure of a music instrument stand includes a first connector and a second connector. Each of the connectors has an annular gear part that matches with each other. A first through hole and a second through hole are formed at the center of the annular gear parts of the two connectors, respectively. A screw is fastened from the first through hole to the second through hole and fixed so that the two connectors can pivotally rotate. Each of the connectors has a groove for the disposition of a bar. A corresponding cover covers the bar and is fixed by a screw and a nut.
