When the outlet size of the rubber condenser 8 is large and the focusing intensity is weak, the moving ring 2 is driven to move, so that the moving ring 2 is away from the slide rail 5, thereby driving the support rod 3 to move. When the support rod 3 moves, it will drive the slider 4 to move, so that several sliders 4 are close to each other, thereby making several movable rods 6 close to each other, thereby making several fixed blocks 7 close to each other, thereby reducing the gap between the four fixed blocks 7, and the outlet of the rubber condenser 8 will shrink accordingly, thereby reducing the outlet of the rubber condenser 8, thereby reducing the focusing range of the device, thereby improving the focusing intensity.
