Abstract
The invention relates to a lens with a photosensitive assembly withdrawing function. The lens with the photosensitive assembly withdrawing function comprises a substrate, a photosensitive assembly, a lens cone, a lens and a withdrawing mechanism. The photosensitive assembly can be arranged on the substrate between an acting position and a withdrawing position in a reciprocating motion mode by the aid of the withdrawing mechanism. When the photosensitive assembly is located at the acting position, the lens cone is located at a first position where the distance between the lens cone and the substrate is large, and the optical axis of the lens and the photosensitive assembly are intersected. When the lens cone moves to a second position where the distance between the lens cone and the substrate is small, the photosensitive assembly moves to the withdrawing position, and the optical axis of the lens and the photosensitive assembly are not intersected.
