1. rotary power tool with light source comprises:

  • One housing;

    One is arranged on the electric notor in the described housing;

    The one elongated main shaft that engages and be suitable for driving with described motor by described motor rotation;

    One is positioned at described spindle nose and extends so that keep the rotatable maintenance assembly of attachment from the front end of described housing;

    Be suitable for by described main axis rotation so that produce alternately at least one magnet in magnetic field;

    One is connected to the front end of described housing and has the sleeve that is generally tubulose interior and outer surface;

    Between the described inner surface of described sleeve and described outer surface, be partially submerged into the light line generating of the front end of described sleeve at least;

    Between the described inner surface of described sleeve and described outer surface, be partially submerged into described sleeve at least so that produce the device of electric current from described magnetic field near described magnet;

    AndBetween described inner surface by described sleeve and the outer surface so that described electric current is fed to the electric conductor of described lighting device from described electric current-producing device.
