The present disclosure does not specifically limit the structure of the supporting mechanism, and it is sufficient that the optical assembly 200 can be stably supported when moving, and all of them belong to the protection scope of the present disclosure. It should be noted that the "optical axis" direction refers to a direction perpendicular to the lens passing through the center of the lens, and is well known to those skilled in the art, and will not be described herein.
