[0035] Working principle: Through the fixing device 2, when it is necessary to fix the music score and adjust the viewing angle, the operator first places the music score on the placing plate 205, so that the edge of the music score is between the elastic piece 206 and the placing plate 205. The music score is fixed by the elastic force of the elastic piece 206 itself. When it is necessary to adjust the viewing angle of the music score, rotate the threaded rod. The threaded rod adjusts its position in the internal thread ring 216. The movement of the threaded rod causes the I-shaped block 214 to rotate in the ring 213 and drives the ring 213 to move. The movement of the ring 213 drives the moving plate 212 to move. The moving plate 212 drives the rack 208 to move. The rack 208 drives the meshing gear 207 to rotate. The rotation of the gear 207 drives the round rod 203 to rotate. The round rod 203 drives the adjusting plate 204 to rotate. The adjusting plate 204 drives the placing plate 205 to rotate around the round rod 203 to adjust the inclination angle of the music score. Through the fixing device 2, the problem that in a traditional digital piano, the place for placing the music score is a flat plate, the music score placing plate 205 has no measures to fix the music score, and the inclination angle of the music score cannot be rotated and adjusted during use, making it difficult to meet the needs of different users and even affecting the performance is solved.

[0036] Through the clamping device 3, when it is necessary to place the unused music score, the operator first pulls the handle 36 in the direction away from the piano body 1. The handle 36 is driven by a pulling force to drive the connecting plate 35 to move. The connecting plate 35 drives the U-shaped elastic piece 33 to move. After the U-shaped elastic piece 33 drives the clamping block 34 to move away from the anti-slip pad 32, the unused music score can be placed on the U-shaped elastic piece 33 through the gap between the anti-slip pad 32 and the clamping block 34. After the placement is completed, the handle 36 can be released. The U-shaped elastic piece 33 rebounds to make the clamping block 34 clamp and fix the music score. Through the clamping device 3, the problem that in a traditional digital piano, it is not convenient to place the unused music score is solved.
