[0024] The rotating mechanism 4 includes: a motor 41, a large gear 42, a small gear 43 and a gear ring 44. The motor 41 is arranged at the bottom of the inner cavity of the rotating base 3. The upper end of the output shaft of the motor 41 is sleeved with a large gear 42, and the outer wall of the large gear 42 is meshed with the outer wall of the small gear 43. The outer wall of the small gear 43 is sleeved with a gear ring 44, and the outer wall of the small gear 43 is meshed with the inner wall of the gear ring 44.
