Since the support arms and the support arms are hinged with the first sliding hinge, the second sliding hinge, the upper base, and the lower base, when the first sliding hinge and the second sliding hinge move toward the middle When the position moves, the seat surface rises, thereby increasing the height. When the first sliding hinge and the second sliding hinge move outward, the seat surface descends, thereby reducing the height. Since the transmission screw is screwed with the sliding hinge, when the height of the seat surface is adjusted There will be no displacement in any direction, and the stability is good; the connecting plate and the mounting plate can also be used for footrest. Directional wheels are arranged under the outriggers, which can make the piano chair move freely and have a brake device to keep it stable.

The beneficial effects of the utility model are:

The utility model is simple in structure and easy to use. The stool surface can be raised and lowered by turning the handle, so that the height of the chair surface can be adjusted. It is suitable for people of different heights and has good versatility. When the height of the chair surface is adjusted, there will be no displacement in any direction, and the stability is good. When the height of the stool surface is adjusted, there will be no displacement in any direction, and the stability is good; there is a storage cavity on the panel, and the musical score can be placed in the storage cavity and other sundries, and at the same time, a locker is set under the chair surface, where different musical instruments can be placed, which increases the entertainment of piano playing and is more ornamental. At the same time, a metronome is set at the bottom of the chair, so that the pianist can better grasp the rhythm when playing.
