[0026] It should be further explained that the latch assembly 9 includes a circular groove provided in the rotating sleeve 4, a limiting groove 905 provided on one side of the circular groove, a circular cavity provided in the fixed sleeve 5, a movable rod 902 plugged into one side of the circular cavity, a limiting block 901 fixedly connected to one end of the movable rod 902, a spring 904 sleeved on the outer surface of the movable rod 902 and a fixed circular block 903 fixedly connected to the other end of the movable rod 902; the cross-sectional dimensions of the outer contour of the limiting block 901 are adapted to the cross-sectional dimensions of the inner contour of the limiting groove 905, and the outer contour cross-sectional dimensions of the limiting block 901 are set to be square, and the inner contour of the limiting groove 905 is The depth dimension is smaller than the depth dimension inside the circular cavity; when the locking cap 6 is separated from the fixed sleeve 5, the fixed round block 903 is moved to one side, so that the fixed round block 903 drives the movable rod 902, thereby making the movable rod 902 move along the inside of the circular groove until the limit block 901 is separated from the limit groove 905, and the spring 904 is compressed at the same time. At this time, the display screen 2 can be rotated by rotating the rotating sleeve 4. After rotating one hundred and eighty degrees, the fixed round block 903 is released, and the spring 904 is reset to drive the movable rod 902 to move, so that the limit block 901 is plugged into the limit groove 905, thereby preventing the rotating sleeve 4 from rotating.

[0027] Furthermore, an annular block is fixedly connected to the end face of the fixed sleeve 5, and an annular groove is provided on the end face of the rotating sleeve 4 close to one end of the rotating sleeve 4, and the inside of the annular groove is rotatably connected to the outside of the annular block; when the rotating sleeve 4 rotates along the fixed sleeve 5, the annular block actually rotates along the inside of the annular groove, thereby facilitating the rotation of the rotating sleeve 4.
