1. An optical element driving mechanism used for driving an optical element, comprising:
a fixed portion;
a driving assembly used for driving the optical element to move relative to the fixed portion in a first dimension;
a support assembly, wherein the optical element is movable relative to the fixed portion through the support assembly, and the support assembly comprises:
an intermediate element, wherein the intermediate element is strip-shaped and extending along a first axis;
a first connecting element having a first opening used for accommodating at least a portion of the intermediate element; and
a second connecting element having a second opening used for accommodating at least a portion of the intermediate element;
a movable portion, comprising:
a first movable portion surface facing the first connecting element; and
a second movable portion surface facing the first connecting element;
wherein:
a first gap is between the first connecting element and the second connecting element;
the first gap is greater than a minimum distance between the first movable portion surface and the first connecting element;
the first gap is less than a minimum distance between the second movable portion surface and the first connecting element.
