1. An optical element driving mechanism, comprising:
a first movable part, including a first optical element;
a fixed assembly, wherein the first movable part is movable relative to the fixed assembly;
a driving assembly, configured to drive the first movable part to move relative to the fixed assembly; and
a locking assembly, configured to position the first movable part at a first position relative to the fixed assembly when the driving assembly does not drive the first movable part to move relative to the fixed assembly,
wherein the fixed assembly includes a first opening for corresponding to a light traveling along a main axis,
wherein the optical element driving mechanism further includes a second movable part and a third movable part, and the driving assembly includes a first driving element for driving the first movable part to move relative to the fixed assembly in a first direction,
wherein the locking assembly includes:
a first locking element, corresponds to a first engaging portion of the first movable part; and
a second locking element, corresponding to the first movable part;
wherein the second movable part is connected to the first locking element,
wherein the third movable part is connected to the second locking element,
wherein the second movable part and the first locking element are integrated formed in one piece,
wherein the third movable part and the second locking element are integrated formed in one piece, and
wherein the driving assembly further includes a second driving element for driving the second movable part to move relative to the fixed assembly.
