[0028] like Figure 5 As shown, the utility model also includes an intermediate rotating shaft 4, which is coaxially arranged with the shaft hole 28. The first screw 5 passes through the first decorative cover 9, the first side ear 31, the first friction pad 6, and the intermediate side plate 27 on one side of the intermediate bracket 21 in sequence and is threadedly connected to one end of the intermediate rotating shaft 4. The first friction pad 6 is pressed between the first side ear 31 and the intermediate bracket 21. The first decorative cover 9, the first side ear 31, the first friction pad 6, and the intermediate side plate 27 on the same side are pressed by the first screw 5. The friction force between the first friction pad 6 and the first side ear 31 and the intermediate side plate 27 on the same side can adjust and position the installation angle of the display screen support 3.

[0029] The second screw 7 passes through the second decorative cover 10, the second side ear 34, the second friction pad 8, and the middle side plate 27 on the other side of the middle bracket 21 in sequence and is threadedly connected to the other end of the middle rotating shaft 4.

[0032] A second arc 36 is provided in the second notch 35 . The second arc 36 is an outwardly convex arc. The protrusion 29 in the second notch 35 presses against the second arc 36 . The second arc 36 can ensure that the protrusion 29 in the second notch 35 can move smoothly.

[0033] like Figure 6 As shown, the protrusion 29 includes a blocking piece 291, and the blocking piece 291 is connected to the square opening 293 of the middle side plate 27 through an arc segment 292, and the blocking piece 291 is placed in the corresponding notch.

[0034] By adjusting the screw-in length of the first screw 5, the friction between the first friction pad 6 and the first side ear 31 and the middle side plate 27 on the same side is adjusted. By adjusting the screw-in length of the second screw 7, the friction between the second friction pad 8 and the second side ear 34 and the middle side plate 27 on the same side is adjusted. Under the action of the first friction pad 6 and the second friction pad 8, the angle of the display screen support 3 relative to the auxiliary bracket 2 can be flexibly adjusted. After the adjustment is completed, the display screen support 3 can be locked on the middle rotating shaft 4 and will not rotate at will. The adjustment is flexible and convenient. In addition, under the action of the first notch 32 and the second notch 35, the rotation angle of the display screen support 3 is limited to avoid adjusting the angle too large. The display screen support 3 has a good adjustment effect and is easy to use. It can be widely promoted and used.
