A portable trumpet stand has an instrument bracket, multiple legs and a central post. The instrument bracket has a central hole, a top and a bottom. The legs are mounted pivotally around and protrude out radially from the instrument bracket, and each leg has a proximal end pivotally mounted in the instrument bracket. The central post is mounted slidably in the central hole of the instrument bracket, has a top end, a bottom end and a spherical cushion. The bottom end can be secured in the central hole so the central post protrudes perpendicularly up to be mounted in a cylindrical metal tube of a trumpet to hold the trumpet in position. The portable trumpet stand can be collapsed and stored in the cylindrical metal tube of a trumpet so the portable trumpet stand and the trumpet can be stored in a case altogether.

A pedal assembly has a base and a pedal. The pedal is pivotally mounted on the base and has two mounting sleeve mounted between the base and the pedal. A resilient element is mounted between the mounting sleeves. A retaining element is secured to the base. Each mounting sleeve has a rubbing surface abutting against the pedal. Accordingly, gaps between the mounting sleeves and the pedal due to attrition will be automatically eliminated.

A musical instrument supporting bar with an adjusting device has a cam connected to an end of an inner tube of the supporting bar, which is mounted rotatably and slidably in an outer tube, and a collar mounted around the cam. The cam has an eccentric rod formed longitudinally. A collar is mounted around the eccentric rod, and the cam and the collar are mounted slidably and rotatably in the outer tube. When the inner tube is rotated relative to the outer tube, the eccentric rod is pressed against or released from an inner wall of the outer tube so that the relative position of the inner tube and outer tube can be adjusted conveniently.

A quick-acting telescopic tube has a stationary tube, a detent lining, an extension tube, a lock activating assembly, a bottom plug, an activating rod, a spring and a ball. The detent lining is mounted securely in the stationary tube and has multiple detents. The extension tube is mounted movably in the detent lining and has a top and a bottom. The lock activating assembly is mounted around the top of the extension tube and has a lever extending into the extension tube. The bottom plug is mounted securely in the bottom of the extension tube and has a transverse through hole. The activating rod is mounted in the extension tube, connects to the lever and has a locking piston with an annular recess. The ball is mounted in the transverse through hole and selectively in either one of the detents or the annular recess.

A snare-adjusting device for adjusting a tension of a snare on a snare drum has a drum mount, a slide assembly and a tone lever assembly. The drum mount is mounted the snare drum and has a slide cavity, an opening and multiple blind holes. The slide assembly is mounted in the drum mount and has a slider and a snare fastener. The slider is mounted slidably in the slide cavity and has an inclined slot. The snare fastener is mounted to the slider and holds the snare. The tone lever assembly is mounted pivotally on the drum mount and has a tone lever, a sliding member and an alignment member. The sliding member is mounted slidably the inclined slot in the slider. The alignment member detachably engages one of the blind holes. Pivoting the tone lever to align with different blind holes easily changes the tone of the snare.

A musical instrument stand with a self-locking neck lock assembly for a guitar-shaped musical instrument has a post, multiple legs and a self-locking neck lock assembly. The self-locking neck lock assembly is attached to the post and has a stationary bracket, two locking palms, a movable bracket and a spring. The stationary bracket is attached securely to the post and has a U-shaped stationary collar having two distal ends. The locking palms are rotatably mounted on respectively the distal ends. The movable bracket is mounted pivotally on the stationary bracket and has a U-shaped movable collar. The movable collar has two distal ends mounted slidably to the palms to open or close the palms. The spring is mounted between the stationary and movable brackets and biases the movable collar upward to open the palms. When the movable bracket pivots down, the locking palms pivot to lock the neck.

An instrument support has a bracket provided with a first leg, a second leg, a disk and two forks. Each of the first leg and the second leg has a through hole defined in a side face of the first leg and second leg to communicate with an interior of the first leg and second leg to receive therein a spring-ball combination. A fork is movably and respectively received in the first and second legs and has an adjustable rod integrally formed with the fork and having recesses defined in a side face of the adjustable rod to correspond to the spring-ball combination so that movement of the two forks provide adaptation to thickness of different instruments.
