Musical instrument stand

Abstract

This invention relates to a musical instrument rack, comprising: a connecting frame, a bracket arm assembly, and a limiting mechanism. The bracket arm assembly is connected to the connecting frame to form a clamping area for clamping musical instruments. The movable bracket arm of the bracket arm assembly can move along a moving axis to expand or shrink the clamping area. The limiting mechanism is disposed on the connecting frame, and the actuating member of the limiting mechanism moves along a braking axis, allowing the movable member of the limiting mechanism to separate from the movable bracket arm, thereby allowing the movable bracket arm to move freely relative to the connecting frame. The resetting member of the limiting mechanism can then drive the movable member to contact the movable bracket arm, thereby preventing the movable bracket arm from moving. In this way, the movable bracket arm, in conjunction with the limiting mechanism, can flexibly adjust the size of the clamping area, allowing musical instruments of various sizes and profiles to be clamped by the bracket arm assembly, thus increasing the practicality of the musical instrument rack.
