The shaft adapter 12 is arranged on the side of the fixed seat 1125 close to the ball head 1111. A notch 1128 is provided on the second fixed portion 1127, and a transition portion 1129 is formed between two adjacent notches 1128. A second protrusion 122 is provided on the side of the shaft adapter 12 away from the fixed seat 1125. A second fastener is arranged to pass through the transition portion 1129 and the second protrusion 122 in sequence to connect the transition portion 1129 with the second protrusion 122.

[0064] The arc-shaped connecting portion 2102 at the other end of the support member 21 is partially thinned along the thickness direction to form a mounting portion 211, and a first protrusion 2111 is provided on the mounting portion 211, and the notch 1128 is matched with the first protrusion 2111.

B is mainly to match the size of F, and F is the outer diameter of the first fixing portion 1126. To ensure the strength after locking, G>6mm, by limiting the size of I and the size of G, the shaft joint 1112 and the shaft limit sleeve 13 are interference fit. Wherein, I is the width of the limiting hole 1321, and G is the outer diameter of the shaft joint 1112. H>4mm, H is the height of the shaft joint 1112, mainly to match the depth J of the limiting hole 1321.

[0070] E is the clearance between the shaft limiting sleeve 13 and the shaft 11 after they are matched, that is, the clearance between the first fixing portion 1126 and the inner side of the limiting sleeve body 131, that is, the clearance between the limiting strip 1311 and the first fixing portion 1126. In the initial state, the shaft limiting sleeve 13 and the center of the shaft 11 coincide. When E is 0, the shaft 11 cannot rotate any more, so the initial clearance is strongly related to the maximum rotation angle of the shaft 11.

The side wall of the cylindrical fixing part 151 is arranged adjacent to the side wall of the mounting hole 323, and the bottom wall of the cylindrical fixing part 151 is arranged adjacent to the end cover 132 of the rotating shaft limiting sleeve 13. The limiting part 152 is vertically connected to one end of the cylindrical fixing part 151 away from the rotating shaft limiting sleeve 13, and the bottom wall of the cylindrical fixing part 151 is fixedly connected to the end cover 132, so that the shell is clamped between the limiting part 152 and the rotating shaft limiting sleeve 13.

[0073] A first groove 324 is provided in the area of ​​the rear housing 32 located at the periphery of the end cover 132, the outer diameter of the stopper 152 is larger than the outer diameter of the end cover 132, and a fourth fastener is provided to pass through the first groove 324 and connect with the stopper 152, thereby connecting the shaft fixing member 15 with the rear housing 32 to ensure the connection strength of the entire shaft 11 assembly with the rear housing 32. The degree of freedom adjustment assembly also includes an annular decorative cover 325, which shields the first groove 324 to prevent the fourth fastener from leaking out and affecting the aesthetics of the display device.
