A camera 13 is set up to capture the live broadcast. When the teaching tablet computer 10 rotates, the camera 13 needs to be readjusted. Otherwise, the front of the camera 13 will be covered by the teaching tablet computer 10 and cannot work properly. This application sets a linkage lifting component between the teaching tablet computer 10 and the lifting rod 14. When the teaching tablet computer 10 rotates, it synchronously pushes the camera 13 to rise, thereby realizing automatic adjustment of the height of the camera 13 without manual adjustment, improving the convenience and practicality of operation.

[0035] Please see Figure 2 The lifting rod 14 moves through the top of the bracket 11, and a locking groove is provided at the rear end of the bracket 11. A guide rod 16 is fixedly installed in the locking groove, and a guide block 15 is fixedly connected to one end of the lifting rod 14 inside the cavity of the bracket 11.

At this time, the teaching tablet computer 10 is in a vertical state.

[0042] A drive shaft 28 is movably mounted inside the rectangular box 20. The drive shaft 28 is fixedly connected to the second gear 25. The output shaft of the servo motor 27 is fixedly connected to the third gear 26. The third gear 26 is movably meshed with the second gear 25, and the second gear 25 is movably meshed with the first gear 22.

[0043] Specifically, during operation, the servo motor 27 drives the third gear 26 to rotate, the third gear 26 engages with the second gear 25, and the second gear 25 engages with the first gear 22, thereby driving the first gear 22 to rotate forward and backward.

[0044] The implementation principle of an online teaching live streaming device according to an embodiment of this application is as follows: the camera 13 is used to capture the live streaming screen. When the teaching tablet computer 10 rotates, the camera 13 needs to be readjusted. Otherwise, the front end of the camera 13 will be covered by the teaching tablet computer 10 and cannot work normally. This application sets a linkage lifting component between the teaching tablet computer 10 and the lifting rod 14. When the teaching tablet computer 10 rotates, it synchronously pushes the camera 13 to rise, which improves the convenience of use. When working, the servo motor 27 drives the third gear 26 to rotate. The third gear 26 is in active engagement with the second gear 25. The second gear 25 is in active engagement with the first gear 22, thereby driving the first gear 22 to rotate forward and reverse.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
