1. A driving mechanism, comprising:
a movable portion;
a fixed portion, wherein the movable portion is movable relative to the fixed portion; and
a driving assembly, driving the movable portion to move relative to the fixed portion, comprising:
a biasing element, generating a driving force; and
a first electrical connection portion, electrically connected to the biasing element;
wherein the biasing element is clamped at a first position of the first electrical connection portion by a first clamping force, and the biasing element is clamped at a second position of the first electrical connection portion by a second clamping force, and the first clamping force is different from the second clamping force;
wherein the biasing element includes shape memory alloy, wherein the shape of the shape memory alloy changes as the temperature of the shape memory alloy changes;
wherein the first electrical connection portion includes an end portion corresponding to the biasing element, wherein the end portion at least partially overlaps the biasing element when viewed along a first direction;
wherein the second position is closer to the end portion than the first position;
wherein the first clamping force is greater than the second clamping force;
wherein the direction of the first clamping force is parallel to the first direction.
