Tripod, tripod, platform and sphere cannot be fixed.

The reason why the Yuntai sphere can't be fixed may be:

When using a tripod, it should be placed on a flat and hard ground, otherwise the sphere may be unstable or even fall off. In addition, the central fixing structure below the sphere can realize the rotation of the sphere in any direction, and can also immediately fix the sphere in the central position for 360-degree directional rotation, which is convenient to use. However, it is not easy to fix the sphere in the central position, and it may need to be proofread repeatedly.

If you encounter problems during use, it is recommended to consult tripod manufacturers or professional maintenance personnel.
