The fixedly connected transmission rod 217 will also rotate accordingly and drive the display screen body 6 to adjust the angle. The rotating shaft 211 is rotationally connected to the top of the mounting base 1. The surface of the rotating shaft 211 is fixedly connected with a transmission gear 212. The top of the rotating shaft 211 is fixedly connected with a handle 213. The top of the handle 213 is provided with a card slot 214. The hidden column 215 is fixedly connected to the top of the mounting base 1 and is located on one side of the rotating shaft 211. The inside of the hidden column 215 is rotationally connected with a force gear 216. The top of the force gear 216 is fixedly connected with a transmission rod 217 rotationally connected to the hidden column 215.

[0023] The fixing assembly 22 includes a mounting plate 221, a pull rod 222, a clamping column 223 and a spring telescopic rod 224. By setting the fixing assembly 22, after the angle of the display screen body 6 is adjusted, the pull rod 222 is loosened, so that the clamping column 223 is re-inserted into the inside of the clamping slot 214 under the effect of the spring telescopic rod 224, and the transmission gear 212 is fixed, and the display screen body 6 is fixed accordingly.

[0024] Among them, the mounting plate 221 is fixedly connected to the top of the mounting base 1, and the mounting plate 221 is internally slidably connected with a pull rod 222, the bottom of the pull rod 222 is fixedly connected with a card column 223 embedded in the card slot 214, and the top of the card column 223 is fixedly connected with a spring telescopic rod 224 fixedly connected to the mounting plate 221.

At this time, the card column 223 will move out of the interior of the card slot 214, and the handle 213 loses the fixing force of the card column 223 and becomes a rotatable state. Then the handle 213 is manually controlled to rotate, and the handle 213 immediately drives the rotating shaft 211 to rotate, and the transmission gear 212 will also rotate together. When the transmission gear 212 rotates, it will drive the force-bearing gear 216 to rotate in the hidden column 215, and the transmission rod 217 fixedly connected to the force-bearing gear 216 will also rotate accordingly, and drive the display screen body 6 to adjust the angle. After the adjustment is completed, the pull rod 222 is released, so that the card column 223 is re-inserted into the interior of the card slot 214 under the effect of the spring telescopic rod 224, the transmission gear 212 is fixed, and the display screen body 6 is fixed accordingly.

[0028] When the height of the display screen body 6 needs to be adjusted, the threaded rod 5 can be unscrewed and the display screen body 6 can be pulled upward, so that it drives the adjusting rod 3 to move upward, and the screw hole 4 rises accordingly. At this time, the corresponding positions of the corresponding screw hole 4 and the threaded rod 5 are adjusted. After the adjustment, the threaded rod 5 is tightened inside the screw hole 4 to fix the adjusting rod 3, thereby achieving the purpose of adjusting the height of the display screen body 6.
