In some embodiments, the base 1 includes a base upper cover 11 and a base lower cover 12. The base upper cover 11 is fastened to the base lower cover 12, thereby forming a closed space in the base 1. The upper cover of the base 1 is provided with a shaft hole 13, and the rotating assembly 2 is installed on the shaft hole 13 to realize rotating installation, so that the rotating assembly rotates by taking the shaft hole 13 as a shaft.

In some embodiments, the planar bearing assembly 3 includes an upper bearing 31, a bearing upper cover 33, a lower bearing 32, and a bearing lower cover 34. The upper bearing 31 is mounted on the upper surface of the base upper cover 11, and the lower bearing 32 is mounted on the lower surface of the base upper cover 11.
