The rotating shaft 401 is rotatably installed inside the support frame 3. The L-shaped plate 402 is fixedly installed at one end of the rotating shaft 401. The threaded rod 403 is threadedly installed inside the L-shaped plate 402. The limiting rod 404 is slidably installed inside the L-shaped plate 402. The lower pressing plate 405 is fixedly installed at the bottom of the limiting rod 404. While the lower pressing plate 405 is connected to the limiting rod 404, it is rotatably installed at the bottom of the threaded rod 403. By rotating the threaded rod 403, under the action of the limiting rod 404, the lower pressing plate 405 can move up and down inside the L-shaped plate 402. The support plate 406 is fixedly installed at the bottom of the L-shaped plate 402. Rubber sleeves are provided on the bottom of the lower pressing plate 405 and the top of the support plate 406. The rubber sleeves are provided to increase the friction between the lower pressing plate 405 and the support plate 406 and the LED display screen, so that the LED display screen can be better clamped and fixed. The rotating shaft 401, the L-shaped plate 402, the threaded rod 403, the lower pressing plate 405, the support plate 406 are all one, and two limiting rods 404 are in a group, symmetrically arranged inside the two support frames 3. A sleeve rod is fixedly installed on the side of one of the support plates 406, and a sliding rod is fixedly installed on the side of the other support plate 406. The sliding rod is slidably installed inside the sleeve rod. With this setting, under the action of the moving component 2, the two support frames 3 can drive two groups of this component to move respectively, so that the sliding rod can slide inside the sleeve rod, adapting to LED display screens of different sizes. The turntable 407 is fixedly installed at the other end of the rotating shaft 401. The slider 408 is slidably installed inside the support frame 3. The spring 409 is arranged inside the support frame 3. One end of the spring 409 is connected to the support frame 3, and the other end of the spring 409 is connected to the slider 408.
