the bearing outer ring (11) of the integrated bearing for the transmission of the camera and the bearing outer ring A (21) of the bearing A are coaxially and fixedly arranged on the fixed component, and the bearing outer ring (11), the bearing outer ring A (21) and the fixed component are relatively static;

the bearing inner ring (12) of the camera-driven integrated bearing and the bearing inner ring A (22) of the bearing A are coaxially and oppositely fixedly arranged at two ends of the motion assembly, and the bearing inner ring (12) and the bearing inner ring A (22) and the motion assembly synchronously rotate;

the PCB (16) is in electrical signal connection with the motor (28), and after the PCB (16) sends an electrical signal to the motor (28), the motor (28) drives the bearing inner ring A (22) to rotate and drives the bearing inner ring (12) and the moving component to synchronously rotate.
