[0023] Working principle:
[0024] Example 1
[0025] During use, the tablet computer 5 provides a display of real-time pictures or teaching videos, while the writing whiteboard 6 provides writing conditions for students. When the use angle of the tablet computer 5 or the writing whiteboard 6 needs to be adjusted, the brake servo motor 73 is started, and the brake servo motor 73 drives the transition sleeve 72 and the first protective sleeve 3 to rotate synchronously through the bevel gear box 74 and the second pin shaft until the use angle of the tablet computer 5 or the writing whiteboard 6 is rotated to a suitable angle, and then the brake servo motor 73 is closed.
[0026] When the height of the tablet computer 5 or the writing whiteboard 6 needs to be adjusted, the electric cylinder 9 is started, and the electric cylinder 9 drives the support rod 2, the first protective cover plate 3, the second protective cover plate 4, the tablet computer 5, and the writing whiteboard 6 to be raised or lowered until the appropriate height is reached. After completion, the electric cylinder 9 is closed.
[0027] Example 2
[0028] When the entire device needs to be placed idle, the auxiliary rod 83 can be twisted first to disengage the auxiliary rod 83 from the internal threaded sleeve 82. Then, the second protective cover plate 4 is flipped over until the second protective cover plate 4 covers the top surface of the first protective cover plate 3 with the support of the first protective cover plate 3 and the first pin, and the writing whiteboard 6 covers the tablet computer 5.
[0029] Next, start the brake servo motor 73, which drives the transition sleeve 72 and the first protective sleeve 3 to rotate synchronously through the bevel gear box 74 and the second pin shaft, until the first protective sleeve 3, the second protective sleeve 4, the tablet computer 5, and the writing whiteboard 6 form a composite plate and rotate to an angle perpendicular to the top surface of the hollow base 1, and turn off the brake servo motor 73. In this way, the storage and use effect of the entire device can be achieved.
