[0021] Specifically, the protection structure includes a fixed ring 3, which is sleeved on the cylindrical base 1. A movable connecting ring 4 is movably installed on the lower wall of the fixed ring 3. An inner gear ring 5 is installed on the lower wall of the movable connecting ring 4. A driving component is meshed on the inner gear ring 5.
