The sleeve 201 of the rotating component 2 is precisely fitted and rotated onto the central shaft 1, and the two fit tightly to ensure concentricity during rotation. At the same time, the limiting block 202 fixed on the central shaft 1 plays a key role. The sleeve 201 is fitted and rotated onto the limiting block 202, restricting its smooth rotation within a predetermined range. The locking groove 203 on the limiting block 202 and the locking connector 204 fit together tightly, further enhancing the structural stability. When the computer screen is opened, closed, or the angle is adjusted, the sleeve 201 can rotate smoothly around the central shaft 1 without swaying left or right or shifting up or down, which would affect its use. This lays a solid foundation for the stable operation of the entire positioning mechanism from the source, reduces the probability of failure caused by mechanical loosening, and extends the service life of the equipment.
