Thus, when a tablet personal computer is placed on the base unit, the width adjustment unit is adjusted freely to fit the width of the tablet personal computer, and the height adjustment unit is adjusted freely to fit the height of the tablet personal computer, so that the support device is available for tablet personal computers of different sizes.

Abstract: A musical instrument stand includes a base, a resting member, and two support units. The base includes two elastic units and two slideways. Each of the slideways has a folding recess and an expanding recess. Each of the elastic units includes two elastic strips. Each of the support units includes a pivot rod which has two opposite locking ends and a slide. The locking ends press the elastic strips, and the pivot rod is retained on the base by an elastic restoring action of the elastic strips. The slide slides reciprocally in one of the slideways and is detachably positioned in the folding recess and the expanding recess, so that each of the support units is positioned at a folded position and an expanded position.

Abstract: A musical instrument stand includes a base, two support units, and a backrest unit. The support units are pivotally mounted on two opposite sides of the base. Each of the support units includes a holding portion mounted the top of the base. The backrest unit includes an extension arm disposed between the support units and having a first end pivotally connected with the base, and at least one resting portion mounted on a second end of the extension arm. The backrest unit is movable relative to the base between an expanded position where the resting portion of the backrest unit is far away from the base, and a folded position where the resting portion of the backrest unit is adjacent to the base.

Abstract: A positioning device includes a base, a press board, an antislip piece, and a positioning unit. The base includes an opening, and a mounting space. The mounting space is mounted on a rod. The press board is slidably mounted in the opening. The antislip piece is mounted on the press board and is close to the mounting space. The antislip piece is made of elastic material and is softer than the press board. The positioning unit includes a shaft mounted on the base and a driving member rotatably and eccentrically connected with the shaft. The driving member is driven between a pressing position for locking the rod and a releasing position for unlocking the rod. Thus, the user only needs to drive the driving member to lock or unlock the rod so that the rod is locked or unlocked easily and quickly.

Abstract: A musical instrument stand includes a frame unit, and at least one support unit. The frame unit includes two side modules, a top bar mounted between the side modules, and a bottom bar mounted between the side modules. The support unit includes a supporting seat for supporting a musical instrument, and a mounting sleeve connected with the supporting seat and rotatably mounted on the bottom bar of the frame unit. Thus, the support unit is pivotally mounted on the frame unit, so that a user only needs to place the musical instrument on the support unit and to push the musical instrument toward the top bar of the frame unit, so as to pivot the support unit and to support the musical instrument between the top bar of the frame unit and the supporting seat of the support unit.

Abstract: A musical instrument stand includes a clamping unit and a support unit connected with the clamping unit. The support unit includes a base frame and a connecting module. The connecting module includes a connecting portion and a spherical universal connector. The clamping unit includes a clamp assembly, a spherical mounting seat, and a positioning nut. The mounting seat has an external thread onto which the positioning nut is screwed onto and has a periphery provided with at least two elongate slits. Thus, the mounting seat of the clamping unit is pivotally connected with the universal connector of the support unit so that the support unit can be pivoted relative to the clamping unit so as to adjust the angle of the support unit freely and variably.

Abstract: A musical instrument stand includes an upright rod, a support assembly, and a transverse rod. The support assembly includes a base unit mounted on the upright rod, a holding unit mounted on the base unit, a locking unit connected with the base unit and pressing the holding unit, and a damping member located between the base unit and the holding unit. Thus, the damping member provides a damping effect to the holding unit so that the holding unit is rotated relative to the base unit stably. In addition, the holding unit can be rotated relative to the base unit to adjust the angle of the transverse rod relative to the upright rod and can be moved in the holding unit to adjust the horizontal position of the transverse rod.

Abstract: A musical instrument stand includes a top seat including a seat body and a holding unit. The holding unit includes two pivot members, a torsion spring, and two holding rods. Thus, when the musical instrument is pulled upward relative to the holding unit to detach from the two holding rods of the holding unit, the two pivot members of the holding unit are pushed upward by the restoring force of the torsion spring so that the two pivot members of the holding unit are moved upward to the expanding position, and the two holding rods of the holding unit are moved to space from each other such that the neck of the musical instrument can be removed from the two holding rods of the holding unit easily and conveniently.

Abstract: A musical instrument stand includes a telescopic unit, a braking unit and an operation unit. The telescopic unit includes an outer tube and an inner tube. The braking unit includes a mounting sleeve, a plurality of locking pieces, a pressing block and an elastic member. The operation unit includes a connecting bar, a driven block and an operation handle. Thus, the inner tube is movable successively relative to the outer tube by pressing the operation handle and is locked onto the outer tube immediately by releasing the operation handle to adjust the distance between the inner tube and the outer tube so as to adjust the height of the telescopic unit freely so that the height of the musical instrument stand is adjustable in a stepless manner.

Abstract: Disclosed is a saxophone-supporting stand including two legs and a connective apparatus. The legs can be open and closed. The connective apparatus is used to keep the legs open. The connective apparatus includes a first link, a second link and two rods. The first link includes a first end pivotally connected to one of the legs and a second end. The second link includes a first end pivotally connected to the other leg and a second end pivotally connected to the second end of the first link so that the first and second links are open when the legs are open. Each of the rods is obliquely raised from a related one of the first and second links so that the rods form a V-shaped structure for supporting a portion of the saxophone when the first and second links are open.

Abstract: A wind instrument stand includes a base and a holding unit. The base includes a front support frame and a rear support frame. The holding unit includes a support rod rotatably mounted on the front support frame, two holding members pivotally mounted on the support rod respectively, and two torsion springs each biased between the support rod and the respective holding member. Thus, when the neck of the saxophone is placed between the holding members, the holding members are pivoted and moved toward each other by the weight of the saxophone to clamp the neck of the saxophone, so that the neck of the saxophone is clamped between the holding members exactly and stably to prevent the saxophone from being detached from the holding members due to an accidental vibration or hit.
