Hand-operated power generator

The utility model relates to the technical field of the generating device, especially to a hand-operated power generator applied in various small electric appliances. The hand-operated power generator includes a crank handle, a gear drive, a flywheel and a generator set generating by the flywheel. Between the gear drive and the flywheel is equipped with a ratchet drive mechanism and the gear drive driven by the crank handle drives the ratchet drive mechanism to drive the flywheel. The flywheel of the utility model, in the rotary process, drives the generator set to generate the current. At this time, without continuously shaking the handle, the flywheel can still overspeed under the effect of inertia to drive the generator set to continuously generate the current so that the human power can be saved and the user has no need of continuously shaking the handle. Meanwhile, the utility model simplifies the structure that makes the entire product has simple structure and low cost. In addition, the utility model can also be connected to an accumulator and via the accumulator be connected to the power source input terminal of a luminary or other electric appliances so to compose the commodities with different usage.
