The invention discloses a cell-free multifunctional continuous power-supply lighter which is provided with a shell (27), a bracket (20), a handle (1), a rotating gear as well as a shaft and a bearingthereof, the clockwork spring (18) of a metal band, the rollers (13,14) of the metal band, a generator (10) and an output circuit thereof, a floodlight (25) or an electricity load; the clockwork spring (18) of the metal band is reversely twisted on the two rollers (13,14) of the metal band in an ''S'' shape; a reverse elastic balancer (19) arranged on the bracket (20) is pressured on the clockworkspring (18) of the metal band; a gear cluster driven by the clockwork spring (18) of the metal band is the combination of helical spur gears (4 to 9); a structure the clutch (15) of which is providedwith a ratchet wheel is adopted between the handle (1) and a drive wheel (2); the three-phase electricity given out by the micro-generator (10) after passing through bridge commutation, a constant-flow circuit and a capacitor supplies power for the floodlight (25) or the electricity load. The cell-free multifunctional continuous power-supply lighter can provide continuous power supply and lighting for the areas out of power caused by disasters and can meet the lighting and power supply of field operators at night. The lighter has a simple structure, is easily manufactured, has a low cost andis suitable for the families in a disaster area or the field operators at night.
