1. An optical element driving mechanism, comprising:
a fixed portion;
a first movable portion disposed in the fixed portion and used for moving relative to the fixed portion;
a second movable portion disposed in the fixed portion and used for holding an optical element having a main axis, and the second movable portion is movable relative to the first movable portion;
a first driving assembly disposed in the fixed portion and used for driving the first movable portion to move relative to the fixed portion in a first dimension;
a second driving assembly disposed in the fixed portion and used for driving the second movable portion to move relative to the first movable portion in a second dimension; and
a connecting element connecting the first movable portion and the second movable portion;
wherein:
movement in the first dimension is a circular movement of the first movable portion relative to a first axis extending in a first direction;
movement in the second dimension is a rotational movement of the second movable portion relative to a second axis extending in a second direction;
wherein the second driving assembly comprises a first transmission element disposed between the first movable portion and the second movable portion, used for transmitting a second driving force generated by the second driving assembly to the second movable portion;
