The axial directions of the driving gear 32 and the driven gear 33 may be parallel to each other or perpendicular to each other, as long as the rotation of the driving gear 32 can drive the driven gear 33 to rotate. After the motor 31 receives the instruction of the control module 4, the rotating shaft of the motor 31 drives the driving gear 32 to rotate, the driven gear 33 engaged with the driving wheel rotates, and the driven gear 33 rotates to drive the orientation column 34, the mounting platform 1 and the additional device 11 to rotate.
