[0039] Working principle: When in use, the first two-way threaded rod 9 and the second two-way threaded rod 13 are driven to rotate by the first knob 10 and the second knob 14 to adjust the two upper fixing seats 19 and the two lower fixing seats 11 to a suitable spacing, and then the upper fixing seat 19 is pulled upward to compress the first spring 17 to increase the spacing between the upper fixing seat 19 and the lower fixing seat 11, and at the same time, the four corners of the display screen are placed on the inner side of the upper fixing seat 19 and the lower fixing seat 11, and then the upper fixing seat 19 is released. Under the action of the elastic force of the first spring 17, the display screen is fixed between the upper fixing seat 19 and the lower fixing seat 11, and then the card block 23 is pulled outward. When the card block 23 exceeds the surface of the display screen, the card block is rotated. The block 23 is stuck on the surface of the display screen to limit it and prevent the display screen from sliding down due to looseness. Then, by pressing the control button 35, the electric telescopic rod 3 is controlled to drive the lifting seat 4 to rise or fall, thereby adjusting the height of the display screen. After adjusting the height to a suitable position, the third knob 26 is turned to drive the one-way threaded rod 25 to rotate through the third knob 26, so that the second slider 27 slides along the fourth slide groove 24, and then the support rod 33 pushes the third slider 31 to slide in the fifth slide groove 29, so that the rotating shaft 6 drives the support plate 7 to rotate, thereby adjusting the angle of the display screen. After the display screen is adjusted to a suitable angle, the display screen can be connected to a power source for use.
