And because the driving part is directly connected to the bearing outer ring or the bearing inner ring, when the system stops working, the bearing outer ring or the bearing inner ring connected with the driving part can be kept fixed through the fixed state of the driving part, so that the positioning of the rotating position of the rotating assembly 5 is realized, and the rotating assembly is prevented from continuously rotating to influence the use.

In other embodiments, other driving schemes may be used. For example, the drive shaft of the drive element is in driving connection with the outer bearing ring or the inner bearing ring via a belt. I.e. the tendency of the rotational movement of the drive shaft is transmitted to the first rotation element 51 or the second rotation element 52 by means of a conveyor belt so that they perform a relative rotational movement. This arrangement allows a wider space for the drive member to be installed. In other embodiments, it is also possible to provide the driving member with a driving screw, and the outer ring of the first rotating member 51 or the second rotating member 52 is provided with a docking gear, and the driving screw of the driving member is meshed with the docking gear of the first rotating member 51 or the second rotating member 52.
