Claim 8:
9. A lens device, comprising:
a lens barrel;
a lens disposed in the lens barrel;
a linear reciprocating motion mechanism, comprising:
a first movable part coupled to the lens barrel; and
a second movable part coupled to the first movable part; and
a power machine coupled to the second movable part to be configured to drive the second movable part to rotate along a second axis, thereby driving the first movable part to rotate along a first axis, and the first movable part is configured to drive the lens barrel to perform a linear reciprocating motion along a displacement direction that is non-parallel to the first axis, wherein the second movable part is rotatable N turns by the power machine, the first movable part is rotated by one turn, and N is greater than or equal to 10,
wherein the first movable part includes a worm gear, and the second movable part includes a worm; and
wherein the first movable part comprises a first rotating part and a second rotating part, a rotating axis of the first rotating part is at the center of the first rotating part, a rotating axis of the second rotating part is at the non-center of the second rotating part, the rotating axis of the first rotating part is coaxial with the rotating axis of the second rotating part, and the second rotating part is abutted against the lens barrel.
