[0002] The piano is a keyboard instrument in Western classical music. It has the reputation of "the king of musical instruments". It consists of 88 keys, 52 white keys, 36 black keys and metal string soundboards. Lee invented the piano in 1709. The range of the piano ranges from A027.5Hz to C84186Hz, covering almost all the tones in the music system. It is the instrument with the widest range except the organ. The piano is generally used for solo, ensemble, accompaniment and other performances. Composing and rehearsing music is very convenient. The player presses the keys on the keyboard, moves the small mallet covered with felt inside the piano, and then strikes the steel strings to make sound. The piano needs regular maintenance to ensure its timbre remains unchanged. The piano casters in the prior art include a wheel, a bracket, a central shaft and a bushing that is sleeved on the central shaft. There is a ball between them, and the central shaft rotates and cooperates with the shaft sleeve through the rolling of the ball. The piano caster with the above structure has the following defects in the actual use process: because the existing caster only relies on a ball to roll in the shaft sleeve, it cannot move on the piano frame. During the process, the balls can easily deviate from the predetermined center position under the action of the gravity of the piano frame, causing the balls to be stuck between the bushing and the central shaft, which makes it inconvenient to move the piano. Moreover, the existing casters cannot adjust the height. When the piano is installed, it is necessary to adjust the height of different casters so that the piano is in a horizontal position. During the installation of the piano, the installation of the piano casters is essential, because the piano is heavy and expensive, and more importantly, it is somewhat Loved by lovers, most of the piano casters on the market will bump into the piano when installing the piano casters, and the piano casters cannot be accurately aligned with the piano support legs, which is very inconvenient to use. According to the needs, it is necessary to design a fast Align the piano casters with the piano support legs, not only to prevent bumps, but also to install the equipment very conveniently
