1. An optical element driving mechanism, comprising:
a first holder used for connecting to an optical element;
a fixed portion, wherein the first holder is movable relative to the fixed portion, and the first holder and the fixed portion are arranged along a main axis;
a first driving assembly used for driving the first holder to move relative to the fixed portion;
a first stopping assembly used for restricting the movable range of the first holder relative to the fixed portion;
a second holder used for connecting the optical element and is movable relative to the fixed portion and the first holder;
a second driving assembly used for driving the second holder to move relative to the first holder; and
a bottom affixed on the first holder,
wherein:
when viewed along a first axis perpendicular to the main axis, at least a portion of the bottom is between the first holder and the second holder;
when viewed along the first axis, at least a portion of the second driving assembly is between the bottom and the first holder; and
when viewed along the first axis, at least a portion of the second driving assembly is exposed from the bottom.
