[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. In this embodiment,

[0020] like Figures 1-4The LED high-definition display screen fixing device shown has the following structure: it includes a stand 1, a display screen 2 and other components. The stand 1 is vertically fixed at both ends of the top of the equipment box 3. Each end of the bottom of the equipment box 3 is provided with a support plate 4. The inner side of the stand 1 has a limit groove 5. A vertical lead screw 6 is provided in the limit groove 5. The lead screw 6 can be a ball screw. A servo motor in the equipment box 3 drives the lead screw 6 to rotate synchronously. A slider 7 is provided in the limit groove 5. The lead screw 6 passes through the slider 7 and matches it, so that the lead screw 6 can drive the slider 7 to move up and down synchronously along the limit groove 5. The two sliders 7 are horizontally opposite each other and a crossbar 8 is provided between them.

[0021] Installation and locking of rotating seat 9: A rotating seat 9 is provided in the middle of the crossbar 8. The rotating seat 9 is rotatably installed in the middle of the crossbar 8, and the crossbar 8 at both ends is threaded, called threaded section 81. A locking nut 10 is provided on the threaded section 81. By tightening the locking nut 10, the rotating seat 9 can be locked to the crossbar 8, thereby fixing the rotating seat 9 on the crossbar 8.

[0022] The rotating base 9 is connected to the display screen 2: a short rod 11 is provided on the front side of the rotating base 9, and a ball head 12 is provided at the front end of the short rod 11. A ball seat 13 is provided in the middle of the rear side of the display screen 2, and a spherical cavity 14 is provided in the middle of the ball seat 13.
