1. An optical system, comprising:
a first optical mechanism, comprising:
a movable part;
a fixed assembly, wherein the movable part is movable relative to the fixed assembly; and
a driving assembly, configured to drive the movable part to move relative to the fixed assembly;
a second optical mechanism; and
a third optical mechanism;
wherein when viewed along a first axis, a base of the fixed assembly is disposed between the second optical mechanism and the third optical mechanism;
the optical system further comprises a base plate, and the base of the first optical mechanism, the second optical mechanism and the third optical mechanism are fixedly disposed on the base plate and located on a same plane;
the fixed assembly further comprises an outer frame fixedly connected to the base;
when viewed along the first axis, the outer frame has a long strip-shaped structure extending along a second axis;
the outer frame has a base portion, a first bending portion and a second bending portion;
when viewed along a third axis, there is a gap between the first bending portion and the base plate;
the third axis is perpendicular to the first axis and the second axis; and
when viewed along the third axis, there is another gap between the second bending portion and the base plate.
