A safety lighter includes a gas tank, a wheel racket, a file wheel assembly, and a metal cap. A wheel racket being provided at the top of the gas tank further includes two file-wheel seats having a slot extended up therefrom and a multiplicity of match-up seats. The file wheel assembly made by pressing together a file wheel with relatively smaller shaft diameter and two side wheels having external teeth at the circumference edge and with shaft diameter greater that that of the file wheel has its salient shaft pivotally connected to the slot. The metal cap being slipped on the external portion of the wheel racket has an extension portion provided at a location adjacent to the file wheel assembly. Under normal condition, the extension portion of the metal cap meshes with the side wheels of the file wheel assembly and the external teeth of the file wheel having relatively small shaft diameter such that it is not easy to ignite the lighter by turning the file wheel assembly to rub against the flint since it is propped up by the extension portion. When it comes to ignite the lighter, one needs only to exert a small force to press down the file wheel assembly and the slot will guide the salient shaft of the file wheel assembly to slide downward. After pressing down, the file wheel assembly will separate the prop-up engaging of the extension portion of the metal cap and turn the file wheel assembly to rub against the flint to generate flame to achieve the ignition action. Therefore, the lighter is capable of avoiding the children playing with the lighter to cause hazard.
