Since the second end of the fourth rotating shaft 213 is connected to the mounting block 28, the second rotating shaft 27 rotates and penetrates the mounting block 28, so that the second rotating shaft 27 and the fourth rotating shaft 213 are vertically arranged, thereby ensuring that the fourth rotating shaft 213 moves linearly in the vertical plane and does not rotate, the fourth rotating shaft 213 moves downward to drive the demonstration screen 102 to move downward, and the demonstration screen 102 moves downward to facilitate its storage, so as to prevent the demonstration screen from being easily damaged by external objects when the demonstration device is transferred for secondary use, causing economic losses and inconvenience for the next use. At the same time, the demonstration screen 102 moves downward, driving the moving plate 31 to move downward, the moving plate 31 moves downward, driving the rack to move downward, the rack moves downward, driving the gear 33 to rotate, the gear 33 rotates, driving the fifth shaft 32 to rotate, the fifth shaft 32 rotates, driving the fifth rotating rod 34 to rotate, the fifth rotating rod 34 rotates, driving the sixth shaft 35 to rotate, the sixth shaft 35 rotates, driving the writing board 4 to move inward, and the writing board 4 is convenient to be stored when it moves inward, so as to prevent the demonstration device from being damaged by collision with external objects due to its large volume when it is transferred for secondary use; At the same time, the rotation of the third rotating shaft 29 drives the first sprocket 41 to rotate, and the rotation of the first sprocket 41 drives the second sprocket 43 to rotate. Specifically, the radius of the first sprocket 41 is larger than the radius of the second sprocket 43, so that when the first sprocket 41 rotates a quarter of a circle, it can drive the second sprocket 43 to rotate many circles, and the rotation of the second sprocket 43 drives the seventh rotating shaft 44 to rotate, and the rotation of the seventh rotating shaft 44 drives the sixth rotating rod 45 to rotate, and the rotation of the sixth rotating rod 45 drives the seventh rotating rod 46 to rotate, and the rotation of the seventh rotating rod 46 drives the moving rod 47 to move up and down reciprocatingly, and the moving rod 47 moves up and down reciprocatingly to drive the moving block 48 to move up and down reciprocatingly, and the moving block 48 moves up and down reciprocatingly to drive the first telescopic plate 49 to move up and down reciprocatingly, and the first telescopic plate 49 moves up and down reciprocatingly to drive the slider 411 to move up and down reciprocatingly, and the slider 411 moves up and down reciprocatingly to drive the brush plate 412 to move up and down reciprocatingly, and the brush plate 412 moves up and down reciprocatingly to clean and erase the writing board 4, so as to avoid manual cleaning and erasing after use, which is relatively time-consuming and convenient for next use; At the same time, the moving block 48 reciprocates up and down to drive the eighth rotating shaft 55 to reciprocate up and down; When the eighth rotating shaft 55 moves from the upper side to the lower side, the sliding column 52 moves from the third sliding groove above to the Y-shaped groove. When the sliding column 52 moves to the inclined groove above the Y-shaped groove, since the moving rod 47 is always in a vertical state, the sliding column 52 drives the eighth rotating rod 53 to rotate. The rotation of the eighth rotating rod 53 drives the eighth rotating shaft 55 to rotate. The rotation of the eighth rotating shaft 55 drives the knocking rod 5 to rotate. The second end of the knocking rod 5 rotates from the vertical state to the inclined state. When the sliding column 52 moves to the bottom end of the Y-shaped groove through the upper oblique groove of the Y-shaped groove, the second end of the knocking rod 5 rotates from the inclined state to the horizontal state; When the sliding column 52 moves from the bottom end of the Y-shaped groove to the oblique groove below the Y-shaped groove, the second end of the knocking rod 5 rotates from the horizontal state to the inclined state. When the sliding column 52 moves from the oblique groove below the Y-shaped groove to the third sliding groove below, at this time, the second end of the knocking rod 5 rotates from the inclined state to the vertical state. At this time, the second end of the knocking rod 5 knocks the second telescopic plate 54 located below, thereby driving the writing board 4 to vibrate, thereby improving the cleaning effect of the brush plate 412 on the writing board 4, so that the dust on the writing board 4 falls off quickly. When the eighth rotating shaft 55 moves from the bottom to the top, at this time, the sliding column 52 moves from the third sliding groove below to the Y-shaped groove. When the sliding column 52 moves to the oblique groove below the Y-shaped groove, since the moving rod 47 is always in a vertical state, the sliding column 52 drives the eighth rotating rod 53 to rotate, and the rotation of the eighth rotating rod 53 drives the eighth rotating shaft 55 to rotate. The rotation of the eighth rotating shaft 55 drives the knocking rod 5 to rotate, and the second end of the knocking rod 5 rotates from the vertical state to the inclined state. When the sliding column 52 moves to the bottom end of the Y-shaped groove through the oblique groove below the Y-shaped groove, the second end of the knocking rod 5 rotates from the inclined state to the horizontal state; When the sliding column 52 moves from the bottom end of the Y-shaped groove to the upper inclined groove of the Y-shaped groove, the second end of the knocking rod 5 rotates from the horizontal state to the inclined state. When the sliding column 52 moves from the upper inclined groove of the Y-shaped groove to the upper third sliding groove, the second end of the knocking rod 5 rotates from the inclined state to the vertical state. At this time, the second end of the knocking rod 5 knocks the second telescopic plate 54 located above, thereby driving the writing board 4 to vibrate, thereby improving the cleaning effect of the brush plate 412 on the writing board 4, so that the dust on the writing board 4 falls off quickly. By moving back and forth in this way, the two second telescopic plates 54 can be knocked alternately at the same time, thereby improving the cleaning effect of the brush plate 412 on the writing board 4.

When the writing board moves inward, it is convenient to store it. At the same time, the brush board moves up and down reciprocatingly for cleaning and erasing the writing board, avoiding the need for manual cleaning and erasing after use, which is time-consuming and convenient for next use. By arranging the knocking mechanism, the demonstration screen moves downward to facilitate storage, the writing board moves inward to facilitate storage, and the brush board moves up and down reciprocatingly for cleaning and erasing the writing board, thereby driving the writing board to vibrate, thereby improving the cleaning effect of the brush board on the writing board and allowing dust on the writing board to fall off quickly.
