The sliding operating part 8-7 extends into the mounting groove 8-1a through the sliding groove 8-1b and connects with the pin rod 8-3 to facilitate the operation of the pin rod 8-3.

[0071] See Figure 5 and Figure 6 In order to achieve damped rotation of the front support rod 1-1 and the rear support rod 2-1, the front support rod 1-1 and the rear support rod 2-1 are installed on the main support rod 6-1 via the first screw 9. The first screw 9 passes through the front support rod 1-1 and the rear support rod 2-1 in sequence and is threadedly connected to the main support rod 6-1. The side of the rear support rod 2-1 facing the main support rod 6-1 is provided with a first nut 10 that is threadedly engaged with the first screw 9. A first spring plate 11 is provided between the first nut 10 and the rear support rod 2-1, and between the first screw 9 and the front support rod 1-1, respectively. A first friction plate 12 is provided between the front support rod 1-1 and the rear support rod 2-1. The rear support rod 2-1 is mounted on the bottom support rod 3-1 via a second screw 14. The second screw 14 passes through the bottom support rod 3-1 and the rear support rod 2-1, and is threadedly connected to the second nut 15 inside the rear support rod 2-1. Second friction plates 16 are respectively provided between the bottom support rod 3-1 and the rear support rod 2-1, and between the second nut 15 and the rear support rod 2-1. A second spring plate 17 is provided between the second screw 14 and the bottom support rod 3-1. Among them, the first spring plate 11 and the second spring plate 17 are butterfly spring plates.

[0072] The working principle of this invention is as follows:

[0073] Rotate the first shelf 4 to a horizontal position. The rear side of the first shelf 4 is fixed to the middle of the rear support rod 2-1 via the pin mechanism 8. At this time, the front support rod 1-1, the rear support rod 2-1, and the bottom support rod 3-1 are arranged in a stable triangular structure, which can stably support the display screen 7 and also serve as a shelf, making full use of the space between the front support assembly 1 and the rear support assembly 2 (e.g., Figure 1 and Figure 2(As shown); Rotate the first shelf 4 to a vertical position. After rotating, the front support rod 1-1 and the rear support rod 2-1 will fit together in a vertical position. The pin mechanism 8 is fixed to the upper part of the rear support rod 2-1 on the rear side of the first shelf 4. At this time, the front support rod 1-1, the rear support rod 2-1, and the first shelf 4 are all perpendicular to the horizontal plane and can lean against the wall 19 without tipping over. The entire bracket can be hidden behind the TV cabinet 18 for convenient storage and use. There is no need to drill holes in the wall 19 to install the display screen 7 (as shown). Figures 11 to 13 (As shown).

[0074] In summary, this bracket has a simple structure, is easy to fold and store, and can be used in two different states.
