Improved structure of self-powered flashlight

The utility model discloses an improved structure of a self-powered electric torch, which is mainly composed of a shell, a luminous body, a circuit board, magnets, coils, a back cover and an inner cylinder. Both ends of the moving magnet of the utility model are respectively fixedly connected with a magnet, and the polarity of two magnets is the same to the polarity of a relative surface of the moving magnet. The principle of homogeneity repulsion is used, when two same poles are approached, magnetic fields are stacked. When the magnets move, the efficiency of cutting coils is high, which enables mechanical energy which is used for rocking the magnets to be better converted into electrical energy and thus generating efficiency can be raised.
