A zoom lens includes an external frame, a rotary shaft, an internal frame, a lens group and a spring. The internal frame is connected to the external frame via the rotary shaft, so that the internal frame is rotatable relative to the external frame. The lens group is fixed in the internal frame. The spring comprises a deformation part and two extension parts extended from the deformation part, wherein one extension part is propped against the internal frame and inclined at an acute angle relative to the rotary shaft, and the other extension part is propped against the external frame.

Zoom lens

A lens device includes a base unit, a rotatable barrel component, a press plate, and a lens unit. The base unit includes a base plate, and a stationary barrel component connected to the base plate and extending there from a long an axis. The rotatable barrel component is sleeved rotatably on the stationary barrel component. The press plate has at least one fixing end portion secured to the base unit, and a press section connected to the fixing end portion. The press section is elastically deformable relative to the fixing end portion and is disposed to abut against an annular outer surface of the rotatable barrel component to resist axial movement of the rotatable barrel component. The lens unit is driven to move relative to the base unit along the axis upon rotation of the rotatable barrel component.
