The aperture adjustable lens device described in item 1 or 2 of the scope of patent application further includes: another aperture adjustment blade, the other aperture adjustment blade is connected to the board, wherein the aperture adjustment blade is connected to the other aperture adjustment blade The blades are arranged crosswise; an other driver, the other driver is connected to the other aperture adjustment blade, the other driver displaces the other aperture adjustment blade, wherein the other aperture adjustment blade is provided with another hole, and the other A driver displaces the other hole of the other aperture adjustment blade to a position overlapping with the aperture aperture of the board; wherein the driver is configured to drive the aperture adjustment blade to the open position or the closed position, and the other driver is set It is used to drive the other aperture adjusting blade to the open position or the closed position. As described in item 6 of the scope of patent application, the adjustable aperture lens device further includes: a cover plate, the cover plate is arranged at a distance from the plate, the aperture adjustment blade and the other aperture adjustment blade are arranged on the Between the cover board and the board, The aperture adjusting blade and the other aperture adjusting blade are respectively pivotally connected to the board. For the aperture adjustable lens device described in any one of items 4 and 5 of the scope of patent application, when the driver drives the aperture adjustment blade to be in the closed position and the other driver drives the other aperture adjustment blade to be in the closed position In the open position, the aperture of the lens device is defined by the aperture of the aperture of the aperture adjustment blade; when the driver drives the aperture adjustment blade to be in the open position and the other driver drives the other aperture adjustment blade to make it When in the closed position, the aperture of the lens device is defined by the aperture of another hole of the other aperture adjusting blade. The aperture adjustable lens device according to any one of items 3 and 5 of the scope of patent application, wherein the aperture adjustment blade includes an arc profile, and the other aperture adjustment blade includes another arc profile. When the driver is driven When the aperture adjustment blade is in the open position, the arc profile of the aperture adjustment blade corresponds to a part of the outline of the aperture of the board; when the other driver drives the other aperture adjustment blade to be in the open position, the The other arc profile of the aperture adjustment blade corresponds to another part of the profile of the aperture of the board. As described in any one of items 1 to 4 of the scope of the patent application, the aperture adjustment blade is pivoted on the optical system frame, and the driver has an arc-shaped orbital movement driven by the driver. A rotating rod, the optical system frame has a track hole corresponding to the arc-shaped track, the aperture adjustment blade is provided with a force hole, the rotating rod penetrates the track hole and the force hole, when the rotating rod is subjected to the force hole drive When the actuator is driven to rotate, force is applied to the force application hole, thereby driving the aperture adjusting blade to move to its open position or its closed position. For the aperture adjustable lens device described in any one of items 3 and 4 of the scope of patent application, the other aperture adjustment blade is pivoted on the optical system frame, and the other driver is driven by the other driver. A rotating rod that moves in an arc-shaped orbit, the optical system frame has a track hole corresponding to the arc-shaped track, and the other aperture adjustment blade is provided with a force hole, and the rotating rod penetrates the track hole and the force When the rotating rod is driven by the other driver to rotate, force is applied to the force application hole, thereby driving the other aperture adjusting blade to move to its open position or its closed position.
