Claim:
1. A suspension mechanism installed inside an optical image anti-shake device, the optical image anti-shake device defined with an X-Y-Z orthogonal coordinate system and having a casing, a movable member and a base, the casing having a front end, the suspension mechanism comprising: a movable-member support, formed as a hollow plate structure having a first surface thereof for holding the movable member, a plurality of openings and a plurality of fixation positions; and a suspension module, located between the casing and the base, being hanged fixedly by the plurality of fixation positions of the movable-member support so as to suspend the movable-member support together with the movable member inside an inner compartment formed between the casing and the base, the suspension module allowing the movable member to displace with respect to the base along an X-axial direction and a Y-axial direction and also allowing the movable member to shift at a Z-axial direction, wherein the suspension module further includes a plurality of elastic elements extending individually along directions parallel to the Z-axial direction with an equilibrium arrangement to connect to four corners of the movable-member support via the respective fixation positions and connecting to movable-member support, each of the elastic elements having thereof a first connection end and an opposing second connection end to connect respectively with the casing and the base so as to fix the movable-member support in a middle portion thereof with the movable-member support being closer to the base than the front end of the casing, such that the movable-member support is suspended perpendicular to the Z-axial direction inside the inner compartment by the plurality of elastic elements; wherein a photo axis is parallel to the Z-axial direction; wherein the suspension module is to hang the movable member in a suspension manner and to maintain substantially a Z-axial arrangement of the casing, the movable member and the base along the same photo axis.
