[0035] The working principle of the above embodiment is:

[0036] (1) When the propaganda machine body 5 needs to be cleaned, the first motor 402 is started. The first motor 402 drives the worm 403 to rotate, and the worm 403 drives the worm wheel 405 and the upper first screw 404 to rotate. The upper first screw 404 drives the upper sprocket to rotate. The upper sprocket drives the lower sprocket and the lower first screw 404 to rotate together through the chain. The two first screws 404 rotate simultaneously, driving the movable block 407 to move. The movable block 407 drives the slider to slide inside the slide groove, thereby increasing the stability of the movable block 407 when moving. When the movable block 407 moves, it drives the roller 409 to move through the fixed block 408. The roller 409 slides on the front of the propaganda machine body 5 to clean the dust on the front of the propaganda machine body 5 and prevent the dust from affecting the use of the propaganda machine body 5.

[0037] (2) When the height of the propaganda machine body 5 needs to be adjusted, the second motor 201 is started. The second motor 201 drives the first bevel gear 202 to rotate, and the first bevel gear 202 drives the two second bevel gears 204 to rotate in the opposite direction at the same time. The second bevel gear 204 drives the second screw rod 203 to rotate together. The two second screw rods 203 rotate simultaneously, and the two moving blocks 205 move relative to each other at the same time. The moving block 205 slides on the slide rod, which increases the stability of the moving block 205 when it moves. When the moving block 205 moves, it drives the hinge rod 206 to rotate, and drives the shell 3 and the propaganda machine body 5 to move together through the hinge rod 206. When the shell 3 moves, it drives the limit block to slide on the limit rod, which increases the stability of the shell 3 and the propaganda machine body 5 when they move, making it convenient to change the height of the propaganda machine body 5 and facilitating use.
