The support frame 4 can support the fixed frame 1 to prevent the fixed frame 1 from being too low and causing discomfort to the teacher, thereby increasing the practicability of the device.

[0025] The inner wall of the fixed frame 1 is rotatably connected to two rotating rods 204, the outer surface of each rotating rod 204 is rotatably connected to the inner wall of the movable plate 201, the top of each rotating rod 204 is fixedly installed with a threaded rod 205, the top of each threaded rod 205 is rotatably connected to the inner top wall of the fixed frame 1, four connecting plates 6 are fixedly installed on the bottom surface of the support plate 5, and the bottom surface of each connecting plate 6 is fixedly installed with a universal wheel 7, and the universal wheel 7 can be fixed by the connecting plate 6, so as to facilitate the movement of the device and increase the convenience of moving the device.

[0026] The outer surface of each threaded rod 205 is threadedly connected to a movable block 206, and the bottom surface of each movable block 206 is in contact with the upper surface of the movable plate 201. The dust removal mechanism 3 includes a collecting box 301, and the upper surface of the collecting box 301 is fixedly connected to the bottom surface of the fixed frame 1. The upper surface of the support plate 5 is fixedly installed with a limiting block 8, and the side surfaces of the two limiting blocks 8 that are close to each other are respectively fixedly connected to the two side surfaces of the support frame 4.
