[0027] A connecting gear 211 is fixedly installed on the outer surface of the rotating shaft 205, and a toothed disc 212 is fixedly installed on the outer surface of the rotating rod 209. The outer surface of the toothed disc 212 meshes with the outer surface of the connecting gear 211. The toothed disc 212 is an incomplete gear. A connecting bearing 10 is fixedly installed on the upper surface of the turntable 208. The upper surface of the inner ring of the connecting bearing 10 is fixedly connected to the inner top wall of the connecting box 202, and the bottom surface of the outer ring of the connecting bearing 10 is fixedly connected to the upper surface of the turntable 208. The installation of the connecting bearing 10 plays a role in stabilizing the turntable 208, thereby preventing the turntable 208 from shaking when rotating.

[0028] A rack plate 213 is slidably connected inside the connecting box 202. The front of the rack plate 213 meshes with the outer surface of the connecting gear 211. The toothed disc 212 alternately meshes with the rack plate 213 and the connecting gear 211. A slide plate 11 is fixedly installed on the back of the rack plate 213. A slide rail 12 is provided on the inner wall of the connecting box 202. The slide plate 11 is slidably connected inside the slide rail 12. The installation of the slide plate 11 and the slide rail 12 restricts the movement trajectory of the rack plate 213, thereby ensuring the stability of the movement of the rack plate 213.

[0029] The working principle of this utility model is as follows: In use, the teacher opens the electric push rod 203 via an external remote control device. The power provided by the electric push rod 203 drives the movable seat 204 to move, thereby causing the movable seat 204 to rotate in conjunction with the slider 7 to move the connecting box 202. This allows the teacher to adjust the angle of the multimedia main body 206 according to the position of the students at the back of the classroom, making it easier for them to view the content. When it becomes inconvenient for students on the sides of the classroom to view the teaching content on the multimedia main body 206, the teacher opens the rotating motor 207 via the external remote control device. The power provided by the rotating motor 207 drives the turntable 208 to move... The rotating disc 208 intermittently drives the connecting piece 210 to rotate, which in turn drives the rotating rod 209 and the toothed disc 212 to rotate intermittently. At the same time, the toothed disc 212 alternately meshes with the connecting gear 211 and the rack plate 213, so that the toothed disc 212, in conjunction with the rack plate 213, drives the connecting gear 211 to rotate back and forth, which in turn drives the rotating shaft 205 to rotate back and forth. This causes the multimedia main body 206 to swing back and forth intermittently during the display, making it convenient for students in different positions to view, thereby improving the teaching quality of teachers.
