Abstract

The utility model discloses a portable acoustic tester for music teaching, which relates to the technical field of music teaching and comprises an acoustic tester, wherein a casing component is arranged on the surface of the acoustic tester, and a clamping mechanism is arranged on the surface of the casing component. According to the utility model, the threaded column is connected with the shell assembly, when the clamping slot of the U-shaped frame is aligned with the desk side, the pressing block is pressed down, so that the movable column pushes the clamping plate to slide on the surface of the guide block, the first spring is compressed at the moment, meanwhile, when the movable column is displaced downwards, the inclined surface at the upper end of the clamping groove contacts with the inclined surface of the clamping block, so that the sliding plate slides on the surface of the sliding rail, when the clamping plate is matched and clamped on the desk side with the U-shaped frame, the clamping block is clamped with the vertical surface at the lower end of the clamping groove, when the clamping plate is required to be loosened, the connecting seat is matched and pressed with the vertical plate to compress the second spring, and meanwhile, the sliding plate slides on the surface of the sliding rail, so that the clamping block is separated from the clamping groove, and the first spring rebounds to drive the movable column to slide upwards, so that the clamping plate loosens the desk side.
