The front and rear sides of the frame 4 are respectively provided with a coaxial U-shaped movable cavity 41 and a motor fixing cavity 42. A geared motor 5 is installed in the motor fixing cavity 42. The output shaft of the geared motor 5 is connected to a pinion 6. A large gear 7 meshes with one side of the pinion 6. The large gear 7 is driven by an eccentric shaft 8 in the shape of a cylinder. The bottom surface of the eccentric shaft 8 is provided with a connection to the middle part of the large gear 7. The lower eccentric rod 81 is connected to the eccentric shaft 8. The outer surface of the eccentric shaft 8 is fitted with a bushing 9. The bushing 9 is movably placed in the U-shaped movable cavity 41. The bushing 9 has a hollow part with an elliptical cross-section. The eccentric shaft 8 is built into the hollow part. A heat sink 10 is fixed on the side of the bushing 9 facing the front opening of the U-shaped movable cavity 41. An LED light source module 11 opposite to the zoom lens 3 is fixedly installed on the front side of the heat sink 10. The heat sink 10 and the LED light source module 11 are provided with corresponding screw holes and are fixed together by through screws. An LED driver module 12 connected to the LED light source module 11 is fixed on the side of the frame 4.
