A limiting sleeve is slidably sleeved on the outer side of one end of the second positioning rod, and the limiting sleeve is fixedly connected to the bottom surface of the screen bracket. One end of the first and second positioning rods can be respectively engaged in the first and second grooves. A control component is installed between the two sets of positioning components, and the control component is drivenly connected to the first positioning rods of the two sets of positioning components.

[0008] Preferably, a limiting groove is provided inside the front end of the outer frame, and the limiting groove has an inverted "L" shape.

[0009] Preferably, a filler block is adhered to the center of the front end of the display screen body, and the filler block can be embedded in the limiting groove.
