The front and rear side walls of the vertical plate 8 are movably connected to the clamping blocks through the rotating shaft. 9. The other side of a pair of clamping blocks 9 is fixedly connected to a support plate 10. The front and rear side walls of the vertical plate 8 are fixedly connected to a limit block 11. A vertical rod 12 passes through the limit block 11. The top of the vertical rod 12 is fixedly connected to an adjusting block 13.

The bottom of the cross block 15 is fixedly connected to a number of blocking blocks 16. Two pairs of L-shaped blocks 17 are sleeved on the support plate 10. The side walls of each pair of L-shaped blocks 17 are fixedly connected to a mounting block 18, and the mounting block 18 is provided with a number of positioning holes 19.

[0027] The TV viewing distance can be adjusted by arranging the movable block 4, the connecting block 6, the fixed block 7 and the vertical plate 8.

[0028] By arranging the vertical rod 12, the adjustment block 13, the spring 14, the vertical rod 12, the horizontal block 15, the blocking block 16 and the clamping block 9, the tilt angle of the TV can be adjusted, thereby improving the convenience of watching TV.

[0029] When in use, the TV bracket bolts are passed through the positioning holes 19, and then the TV is fixed to a pair of mounting blocks 18 by the TV bracket bolts. When the TV viewing distance needs to be adjusted, the mounting blocks 18 are pulled, and the mounting blocks 18 drive the vertical plates 8 to move. The vertical plates 8 pull the connecting blocks 6 to rotate through the fixing blocks 7, thereby changing the TV viewing distance.

The adjusting block 13 is released, and then the adjusting block 13 is pulled downward by the spring 14 to move. The adjusting block 13 pushes the horizontal block 15 and the blocking block 16 downward through the vertical rod 12 to move, thereby clamping the clamping block 9 to fix the TV angle.

[0033] In other feasible connection methods, a pair of clamping blocks 9 are symmetrically arranged about the central axis of the support plate 10 .

[0034] In the technical solution of the embodiment of the present application, the fixing stability of the support plate 10 is improved by symmetrically arranging the clamping blocks 9 .

[0035] In other feasible connection modes, each pair of connection blocks 6 is symmetrically arranged about the central axis of the movable block 4 .

[0036] In the technical solution of the embodiment of the present application, the connection blocks 6 are symmetrically arranged to improve the moving stability of the television.

[0037] In other feasible connection methods, a plurality of positioning holes 19 are distributed on the mounting block 18 at equal intervals.

[0038] In the technical solution of the embodiment of the present application, the positioning holes 19 are arranged at equal intervals to facilitate adaptation to the position of the TV connection hole.

[0039] In other feasible connection modes, each pair of L-shaped blocks 17 is symmetrically arranged about the central axis of the support plate 10 .

[0040] In the technical solution of the embodiment of the present application, the L-shaped blocks 17 are symmetrically arranged to improve the fixing stability of the support plate 10.
