The first push switch 403 is electrically connected to the dual-axis motor 202, the cylinder 2124, the motor 2092 and the first servo motor 206. When it is necessary to turn the page, the output end of the cylinder 2124 contracts, and the clamping plate 2122 is relaxed to release the paper. The dual-axis motor 202 rotates, and under the action of the main shaft 203, the first straight groove plate 204 and the second straight groove plate 205 are moved to the surface of the paper that needs to be turned, and then the motor 2092 rotates, and the first rough sleeve 2091 on the revolution shaft 209 moves the paper to a bowed state, and the bowed part of the paper is located between the rotation shaft 210 and The motor 2092 continues to rotate between the revolution axis 209 until the side edge of the paper leaves the revolution axis 209, and then the first servo motor 206 rotates, driving the first rotating plate 207 and the second rotating plate 208 to rotate. At this time, the driving shaft 211 and the revolution axis 209 rotate 180 degrees around the rotation axis 210 until the driving shaft 211 is located on the back of the turned paper. The dual-axis motor 202 drives the main shaft 203 to rotate, flips the turned paper to the left, and then repeats the above-mentioned loosening action of the cylinder 2124 on the clamping plate 2122. After the paper is attached to the first teaching board 201, the cylinder 2124 is set in the opposite direction to press the clamping plate 2122 to fix the paper. When playing and learning in a standing posture, the second servo motor 306 drives the second gear 3061 to rotate, so that the third rotating plate 303 drives the revolution wheel 304 to rotate, and the right half of the paper is partially lifted and in a partially arched state. At this time, under the action of the first bevel gear 308 and the second bevel gear 309, the third gear 310 drives the crescent plate 311 to rotate, and the crescent plate 311 moves the right paper to the left, completing the page turning.
