At this time, the player 15 is located at the top of the protective shell 1, and the student can be lectured through the player 15. When the player 15 is used, the servo motor 23 is started again, and the output shaft of the servo motor 23 drives the threaded rod 24 to rotate clockwise. When the threaded rod 24 rotates clockwise, the placement seat 14 moves downward, when the placement seat 14 moves downward, the rack 1601 is inserted into the cylindrical frame 18, and the gear 19 rotates, so that the player 15 is more stable when it is reset. When the placement seat 14 moves downward, the second clamping column 1401 moves downward. When the second clamping column 1401 moves to the lower part of the moving rod 20, the second spring 21 is reset, and then the wheel 4 is reset. If the player 15 is damaged and needs to be repaired, just grab the handle 17 with two hands and pull it upward, the player 15 will be separated from the placement seat 14 until the player 15 is pulled out of the protective shell 1 and sent for repair. After the repair, put it back and then cover the cover 10.
