Claim:
A musical instrument stand for a guitar-shaped musical instrument comprising: a post having a top end and a bottom end; multiple legs attached to the post close to the bottom end and extending radially out from the post; and a self-locking neck lock assembly attached securely to the top end of the post and having a stationary bracket attached securely to the top end of the post and: having a mounting bracket being hollow, attached securely to the top end of the post and having two sidewalls; a longitudinal leg attached securely to the top end of the post and having a top end; and a transverse arm formed on and extending perpendicularly from the top end of the longitudinal leg and having a distal end; and a stationary collar being U-shaped, formed on the distal end of the longitudinal leg and having two distal ends separated by a distance; and a gap defined between the distal ends of the stationary collar; two locking palms pivotally attached perpendicularly respectively to the distal end of the stationary collar, and each locking palm having an inner surface; a proximal end; a distal end; a length shorter than half the distance between the distal ends of the stationary collar; a slot defined longitudinally in the inner surface close to the distal end of the locking palm and facing the stationary collar; a through hole defined close to the proximal end of the locking palm and corresponding to one of the distal ends of the stationary collar; and a fastener passing through the through hole in the locking palm and rotatably holding the locking palm on the distal end of the stationary collar; a movable bracket attached pivotally to the stationary bracket and having a pivot bracket mounted pivotally between the sidewalls of the mounting bracket in the transverse arm and having two side edges, a rear end, a front end, a top and two connectors; and a movable collar being U-shaped and narrower than the stationary collar, formed on the front end of the pivot bracket and having two distal ends slidably mounted respectively in the slots in the locking palms; and a gap defined between the distal ends of the movable collar; and a spring mounted inside the mounting bracket and pressing against the pivot bracket to move the movable bracket upward and open the locking palms.
