1. An aperture assembly, used in an optical lens system, the aperture assembly comprising:
a plate, comprising a hollow portion and a non-hollow portion, wherein the hollow portion is configured to define an aperture of the optical lens system, and a contour of the hollow portion has a non-circular shape;
a first aperture sheet and a second aperture sheet, disposed on the plate, wherein when the first aperture sheet moves along a first direction and the second aperture sheet moves along a second direction, the aperture of the optical lens system is changed such that the optical lens system has a first aperture; when the first aperture sheet moves along the second direction and the second aperture sheet moves along the first direction, the aperture of the optical lens system is changed such that the optical lens system has a second aperture, and wherein the first aperture is different from the second aperture; and
a rotating member, provided with a first force applying member and a second force applying member, wherein the first aperture sheet is provided with a first force receiving member, the first force applying member of the rotating member is adaptive to the first force receiving member;
wherein the second aperture sheet is provided with a second force receiving member, the second force applying member of the rotating member is adaptive to the second force receiving member; and
wherein the first force receiving member of the first aperture sheet and the second force receiving member of the second aperture sheet are a first force receiving hole and a second force receiving hole, respectively, the first aperture sheet is provided with a first pass allowing hole, the second aperture sheet is provided with a second pass allowing hole, the first force applying member of the rotating member penetrates the first force receiving hole of the first aperture sheet and the second pass allowing hole of the second aperture sheet, the second force applying member of the rotating member penetrates the first pass allowing hole of the first aperture sheet and the second force receiving hole of the second aperture sheet.
