The ejaculation 22 includes a rectangular base 221 having (4) holes throughout 201142401, and a cylindrical extension tube 222 extending along the periphery of the circular hole 221a toward the opening 121 of the shield 12, as shown in the third and fourth figures. The carrier 22 is further provided with a concave and curved outer surface 223 and an outer surface 224 at two opposite corners of the base 221, and a plurality of slits 225 are concavely formed from the outer surfaces 223 (224), and are cut. The slot 225 is formed in parallel with the axial direction of the metal pin 148, such that each outer surface 223 (224) is formed with a smaller area of the solid surface 223a (224a) on both sides of the slot 225; as for the carrier 22 The inside of the extension cylinder 222 is provided with a lens unit 24 having an optical axis L passing through the opening 121 of the shield 12, and the extension cylinder 222 has a top edge 222a and an outer ring surface 222b. After the lens 20 is installed, The carrier 22 is contacted with the surface of the corresponding metal pin / 148 by the solid surface 223a (224a) to reduce the contact area. When the mirror 20 is reciprocally displaced along the optical axis L, the flat surface can also be reduced due to the frictional resistance. Improved position, further reducing the power output of the motor that pushes the lens 2〇 (not shown) Heart 'reached manner as to reduce the contact friction resistance of the outer' may also choose to create slots in the base of the M arc Qing poured, or to the base 14 and carriage 22 are provided with slots Yide whom. The control unit 3 includes a conductive coil η and a magnet unit material, wherein 1 is electrically conductive, _32_ is wound around the outer ring of the extension tube 222, and is permeable, soldered or coated with a conductive adhesive and the second metal. The lock m is electrically connected; the magnet 4 is composed of a plurality of magnets 341 which are arranged between the fresh 12 and the turtle 22 and are located outside the conductive=2, and the current is conducted to conduct electricity and conduct electricity to the conductive metal. 3Q New Zealand - Electromagnetic force pull 201142401 The lens 20 is displaced toward the opening 121 of the shield 12, as shown in the fifth figure, the lens 20 has been subjected to electromagnetic force and moved toward the opening 121. It must be noted that the aforementioned electromagnetic force is also called Lorentz force, and the magnitude of the electromagnetic force is proportional to the magnitude of the current flowing through the conductive coil 32. The flat spring 40 is received in the mirror chamber 16 of the casing 1 and is located near the opening 121. It has an opening 42 to prevent the displacement of the lens 2, and the bottom surface 44 and the lens 20 are mounted. When the top edge 222a of the 22 is in contact, the resilience of the flat spring 40 will generate a reversing force against the lens 20, and the reverse force will resist the electromagnetic force generated by the magnetron 30. A force balance is formed so that the lens 20 can be stably maintained at a fixed position.
