The invention provides a micro-lens movable mechanism protecting structure which is arranged inside a base of a micro-lens focusing structure and comprises an upper cover, a bearing seat, at least anelastic part and at least a protection sheet; the bearing seat is used for bearing a lens; the elastic part is connected with the upper cover and the bearing seat and supports the bearing seat for suspending inside the base so as to lead the bearing seat to focus, move and recover in the vertical direction; the protection sheet is arranged outside the elastic part and is contained in the hollow structure of the upper cover so as to restrict the horizontal movement of the bearing seat and the rotation torsion when the lens is arranged into the bearing seat and prevent the deformation of the elastic part.
