The side wall of the arc-shaped groove and the corresponding position of the drive groove are provided with an installation groove. The drive gear is rotatably connected in the installation groove. An arc-shaped toothed plate is fixed in the drive groove, and the drive gear meshes with the arc-shaped toothed plate.
[0007] Preferably, a servo motor that drives the drive gear to rotate is fixed to the side wall of the mounting slot.
[0008] Preferably, the arc-shaped frame has limiting grooves on both sides, and the sidewalls of the arc-shaped grooves are fixed with limiting blocks that are adapted to the limiting grooves.
[0009] Preferably, a connecting sleeve is fixed to the upper end of the fixed column, the bottom of the rotating rod is rotatably connected to the connecting sleeve, and an anti-slip sleeve is provided at the connection.
[0010] Preferably, a radio module and a playback module are installed on the lower front side of the display screen, and a wiring module is installed on the side of the display screen.
[0011] Compared with the prior art, the beneficial effects of this utility model are: by mounting the front-facing camera on the arc-shaped frame, the camera can be aimed at the desktop after the arc-shaped frame extends, making it more convenient to take desktop photos during online teaching without having to hold up paper teaching materials to aim at the camera, thus making online teaching more convenient.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4This utility model provides a technical solution: including a display screen 1 and a base 2. The display screen 1 is fixed on the base 2. A fixing post 21 is fixed on the upper rear side of the base 2. A rotating rod 22 is rotatably connected to the upper end of the fixing post 21. An mounting sleeve 3 is fixed on the upper front side of the rotating rod 22. An arc-shaped groove 31 is opened in the mounting sleeve 3. An arc-shaped frame 4 is slidably connected in the arc-shaped groove 31. The front end of the arc-shaped groove 31 is an open structure. A camera 5 is fixed to the front end of the arc-shaped frame 4. A driving component is provided between the side wall of the arc-shaped groove 31 and the arc-shaped frame 4. A sound receiving module 11 and a sound playing module 12 are installed on the lower front side of the display screen 1. A wiring module 13 is installed on the side of the display screen 1.
[0019] The drive assembly includes a drive groove 41 and a drive gear 32. The drive groove 41 is located in the middle of the outer wall of the arc-shaped frame 4. The side wall of the arc-shaped groove 31 and the corresponding position of the drive groove 41 are provided with an installation groove. The drive gear 32 is rotatably connected in the installation groove. An arc-shaped toothed plate is fixed in the drive groove 41 and meshes with the arc-shaped toothed plate. A servo motor that drives the drive gear 32 to rotate is fixed in the side wall of the installation groove. Limiting grooves 43 are provided on both sides of the arc-shaped frame 4. Limiting blocks that are adapted to the limiting grooves 43 are fixed in the side wall of the arc-shaped groove 31.
[0020] A connecting sleeve 23 is fixed to the upper end of the fixed column 21, and the bottom of the rotating rod 22 is rotatably connected to the connecting sleeve 23, and an anti-slip sleeve 24 is provided at the connection.
[0021] Working principle: First, the entire device is connected to an external power source. After connecting to a network signal, the camera 5, along with the audio receiving module 11 and the audio playback module 12, are used to achieve the purpose of remote online teaching. On this basis, the servo motor drives the drive gear 32 to rotate. The arc rack 42 drives the arc frame 4 to slide and extend within the arc groove 31. When the arc frame 4 extends out of the arc groove 31, the camera 5 on its front tilts downward, thus capturing the desktop content. Conversely, when the arc frame 4 retracts into the arc groove 31, the camera 5 can capture images horizontally, making teaching assignments more convenient. Furthermore, the rotation of the rotating rod 22 can drive the camera 5 to rotate horizontally, allowing for better adjustment of the working angle.
