Abstract: An easily operating safety lighter includes an actuating lever normally pivotally mounted on a top frame protruding upwardly from a gas container of the lighter for operatively sparking a flint for burning gas emitted from a gas valve of the lighter, a locking stem protruding downwardly from a depression member of the lever to be blocked on a retarding platform formed on a container cover for preventing a depression of the lever for igniting the lighter by a child, a coupling device having a pair of hook members respectively formed on the actuating lever and on the top frame for temporarily holding the actuating lever when pushing the lever frontwardly for unlocking the locking stem from the retarding platform of the container, thereby allowing a downward depression of the lever to enter the locking stem into a cavity recessed in the container cover for operatively igniting the lighter, and a restoring spring normally urging the locking stem of the actuating lever rearwardly when uncoupling the pair of hook m
