Classification: CPC G  H | IPC G  H

Claim 13:
14. An optical mechanism, comprising:
a movable module, for connecting an optical element, and comprising a holder, wherein the holder comprises:
a hollow main body, having a connection surface;
a restricting portion, having an upper surface and protruding outward from the main body in a horizontal direction perpendicular to an optical axis of the optical element;
a fixed module, wherein the movable module moves relative to the fixed module within a moving range;
a driving assembly, having a coil and a magnet for driving the movable module to move relative to the fixed module, wherein the restricting portion restricts the coil in a predetermined position on the holder;
a first resilient element, having a first connecting portion, a second connecting portion, and a deformable portion connecting the first connecting portion with the second connecting portion, wherein the first and second connecting portions respectively connect to the fixed module and the connection surface of the main body, and the upper surface faces the deformable portion;
a housing, forming an inner surface; and
a quadrilateral base, having a bottom plate and two protrusions each protruding from the bottom plate and toward the magnet;
wherein when the movable module is located at any position within the moving range, the upper surface and the first resilient element are spaced apart from each other and at least partially overlap along the optical axis;
wherein the housing has a top portion and four sidewall portions, and a depressed structure is formed at a corner of the top portion and located adjacent to one of the four sidewall portions, wherein the depressed structure and the magnet at least partially overlap when viewed along the optical axis;
wherein the protrusions of the quadrilateral base each forms an outer surface adjacent to the housing and substantially parallel to the optical axis;
wherein the quadrilateral base further comprises a recess, and the recess is formed between the two protrusions of the quadrilateral base and corresponds to the magnet;
wherein the recess forms a sloped surface that extends toward the housing to an edge of the quadrilateral base.
