A stand adjustment device has a tripod-connecting member, a connecting seat, a distal clamping plate, a boom-connecting tube, a locking shaft, and a manual operating member. The connecting seat is rotatably located around the tripod-connecting member. The distal clamping plate is detachably attached to a side of the connecting seat. One end of the locking shaft is movably disposed in the boom-connecting tube. The boom is slidably mounted through the boom-connecting tube and the locking shaft. The locking shaft is slidably mounted through the boom-connecting tube, the distal clamping plate, and the connecting seat such that the boom-connecting tube is rotatable relative to the connecting seat. The manual operating member and the locking shaft are configured to clamp the boom-connecting tube, the distal clamping plate, and the connecting seat therebetween into a locked condition.

A stand adjustment device has a tripod-connecting member, a connecting seat, a proximal clamping plate, a boom-connecting tube, a locking shaft, and a manual operating member. The connecting seat is rotatably located around the tripod-connecting member. The proximal clamping plate is detachably attached to a side of the connecting seat. One end of the locking shaft is movably disposed in the boom-connecting tube. The boom is slidably mounted through the boom-connecting tube and the locking shaft. The locking shaft is slidably mounted through the boom-connecting tube, the proximal clamping plate, and the connecting seat such that the boom-connecting tube is rotatable relative to the connecting seat. The manual operating member and the locking shaft are configured to clamp the boom-connecting tube, the proximal clamping plate, and the connecting seat therebetween into a locked condition.

A foldable stand has a base, a riser, and a switching mechanism. The riser is located on the base. The switching mechanism connects the base and the riser such that the riser selectively pivots relative to the base from an upright position to a folded position. The switching mechanism has a locked status and a released status. In the locked status, the switching mechanism prevents the riser from pivoting relative to the base. In the released status, the switching mechanism allows the riser to pivot relative to the base from an upright position to a folded position. The switching mechanism is configured to be switched from the locked status to the released status by rotation of the riser around a centerline of the riser.

Foldable stand

A stand adjustment device has a tripod-connecting member, a connecting seat, two clamping plates, a boom-connecting tube, a locking shaft, and a manual operating member. The connecting seat is rotatably located around the tripod-connecting member. The two clamping plates are detachably attached to two opposite sides of the connecting seat respectively. One end of the locking shaft is movably disposed in the boom-connecting tube. The boom is slidably mounted through the boom-connecting tube and the locking shaft. The locking shaft is slidably mounted through the boom-connecting tube, the two clamping plates, and the connecting seat such that the boom-connecting tube is rotatable relative to the connecting seat. The manual operating member and the locking shaft are configured to clamp the boom-connecting tube, the two clamping plates, and the connecting seat therebetween into a locked condition.

A multi-functional and extendable mounting stand has a clamp and an extending assembly including at least one coupling joint and at least one extending rod arranged alternately and connected sequentially. Each coupling joint has a first connecting seat, a mounting seat mounted on the first connecting seat, a second connecting seat mounted through the first connecting seat and the mounting seat, and a knob connected to the second connecting seat. At least one ends of the extending rod is connected to at least one ends of the at least one coupling joint. The clamp is connected to one end of the extending assembly. A holder, a lighting apparatus or a recording apparatus is connected to the extending assembly and can be adjusted to a height and an angular position that allow a user to use the holder in a comfortable pose or to the best recoding or lighting position.

A cable-driven beater mechanism for a percussion instrument has a base, a transmission shaft pivotally mounted on the base, a beater connected to the transmission shaft, a cable transmission assembly, a restoring spring and a cable. An elongated guiding slot is formed in the standing plate. The cable transmission assembly is pivotally mounted on the base and protrudes into the guiding slot. The cable and the transmission shaft are connected via the cable transmission assembly. Pulling force from a player is transferred via the cable to pivot the transmission shaft and the beater. The restoring spring returns the transmission shaft and the beater to an original position. The cable moves along a straight line during operation to reduce rubbing and repeated bending of the cable, which prolongs service life of the cable, reduces noise during operation, and allows the beater to respond more swiftly to the pulling force.

Provided is a current supply for providing a charge current to a load. The current supply includes: a driving transistor, providing the charge current to the load; a sensing transistor, limiting the charge current; a pulling low transistor, pulling low a controlling node which controls the driving transistor and the sensing transistor; a constant voltage controller, pulling up the controlling node, controlling the conduction state of the driving transistor and accordingly maintaining the voltage across the load at the first reference voltage, when a voltage across the load rises up and comes close to a first reference voltage; and a constant current controller, controlling the controlling node and the pulling low transistor to limit the charge current to be constantly provided to the load, when the voltage across the load drops much lower than the first reference voltage.

In a voltage reference circuit, a bandgap reference circuit, for generating a bandgap reference voltage and a reference current, includes an operation amplifier, and a first transistor for providing the reference current. Another transistor mirrors the reference current to provide a first current. A compensation controller converts a node voltage from the bandgap reference circuit into a second current and performs current subtraction on the first current and the second current to provide a compensation feedback current to another node of the bandgap reference circuit. So that, second order temperature compensation is performed on the bandgap reference voltage.
