1. A driving mechanism, comprising:
a fixed part, having a plurality of holes;
a movable part, connected to the fixed part; and
a driving assembly, configured to impel the movable part relative to the fixed part, whereby the driving mechanism is switchable between an open state and a closed state;
wherein when the driving mechanism is in the open state, light propagates through the driving mechanism via the holes, and when the driving mechanism is in the closed state, the holes are blocked by the movable part;
wherein the movable part has a first optical element and a second optical element, and the holes includes a first hole, a second hole, and a third hole, wherein the first hole is larger than the second and third holes, and when the driving mechanism is in the closed state, the first hole and the first and second optical elements partially overlap when viewed in a vertical direction.
