The present invention provides some configurations of flexible connections jointly or integrally formed with a movable part and/or a fixed part of a lens module. The flexible connections may move the movable part along an optical axis direction and/or directions perpendicular to the optical axis. The configuration and material of the flexible connections provide an enhanced strength bearing plastic deformation, and hence increasing the structure strength of the lens module. The formation of the flexible connections with the movable part and/or the fixed part with one mold-injection process can reduce parts of the lens module and simply its manufacturing process.
