A folding frame for supporting a musical instrument is disclosed. The frame includes a first leg and a second leg pivotally connected to each other. The first leg is formed with a disk defining a plurality of holes. The second leg is formed with a spring-loaded pin that tends to be moved into one of the holes in the disk. A handle is pivotally connected to the second leg, and has a first end spaced from the second leg and a second end engaged with the pin. Therefore, the pin can be moved out of one of the holes in the disk simply by pressing the first end of the handle towards the second leg.
