This invention relates to a locking device applied to the supporting stand of percussion instruments, for example snare stand, tom-tom holder, cymbal stand, timbales stand and all kinds of joints of drum outfits, etc., which locking device allows the splaying angle of the two arms to be adjusted to any operable degree without the inconvenient constraint of the calibrating teeth, thereby largely simplifying the operating procedure and enhancing the practicality thereof.
