Variable-focal-length multi-focus visual lens

The utility model discloses a multi-focus visual lens with a variable focal length. The lens comprises a lens shell and a pair of light holes formed in the lens shell, a first lens group, an aperturecomponent and a second lens group are arranged in the lens shell, a first driving mechanism and a second driving mechanism are arranged in the lens shell, and a third driving mechanism is arranged outside the lens shell. The driving mechanism is used for controlling the relative movement of the lens group and the overall movement of the first lens group and the second lens group of the multi-focusvisual lens, and the distance between the lens group and the photosensitive element CCD or CMOS is changed in the overall movement process of the lens group, so that the adjustment of the image distance of the multi-focus visual system is realized. According to the utility model, a rotary motion mode of a traditional camera lens group is changed into a linear motion mode, the manufacturing difficulty is reduced, accurate
