1. An optical element driving mechanism, comprising:
a fixed part, comprising:
a base;
a first wall, extending from the base; and
a first fixed wire gripper, disposed on the first wall;
a movable part, comprising:
a holder, wherein the holder holds an optical element; and
a movable wire gripper, disposed on the holder; and
a drive assembly, driving the movable part to move relative to the fixed part, comprising:
a first wire, connected to the first fixed wire gripper and the movable wire gripper,
wherein when the first wire receives a current, the holder is driven to move relative to the fixed part along a first direction;
wherein the fixed part further comprises:
a second wall, extending from the base;
a top cover, disposed on the first wall and the second wall, comprising an optical element opening; and
a second fixed wire gripper, disposed on the second wall,
wherein the drive assembly further comprises:
a second wire, connected to the second fixed wire gripper and the movable wire gripper,
wherein when the first wire receives the current, the holder is driven so that the optical element and the optical element opening at least partially overlap when viewed along a second direction that is perpendicular to the first direction,
wherein when the second wire receives the current, the holder is driven so that the optical element and the optical element opening at least not partially overlap when viewed along the second direction.
