[0040] By starting the second motor 30, the second motor 30 can drive the threaded rod 29 to rotate forward and backward. Then the threaded rod 29 drives the tooth column 26 to move inside the fixed frame 7, causing the tooth column 26 to drive the first gear 27 to rotate. After that, the first gear 27 drives the engaged second gear 28 to rotate, so that the second gear 28 can drive the connecting shaft 9 to rotate. Then the connecting shaft 9 can drive the movable frame 10 to rotate, that is, the movable frame 10 can drive the teaching board 11 to rotate, and thus the deflection angle of the teaching board 11 can be accurately adjusted for better viewing by the trainees.

[0041] Sliding bars 31 are symmetrically arranged on both sides of the tooth column 26, and sliding grooves 32 matching the sliding bars 31 are opened on both sides inside the fixed frame 7. Based on this, by setting the sliding bars 31 and the sliding grooves 32, the tooth column 26 can drive the sliding bars 31 to slide in the sliding grooves 32, thereby greatly enhancing the stability of the tooth column 26 during movement.

[0042] On both sides of the back of the teaching board 11, extension plates 12 are symmetrically arranged, and an extension mechanism is arranged between the two extension plates 12.
