Abstract: A lighter having a safety mechanism comprises a fuel reservoir; an ignition base comprising a supporting frame on each of two opposite sides thereof; an actuating element; and a wheel comprising a rotating shaft on each of two sides thereof. A resilient element is disposed between the supporting frames and provided with a flint. A retaining hole is formed on each of the supporting frames and comprises a first and a second slot, the first slot having a width smaller than a width of the second slot. The rotating shafts are so shaped that they cannot rotate when engaged in the first slots but can rotate in the second slots. The wheel is pivotally connected to the retaining holes by the rotating shafts and is biased by the flint on the resilient element so that the rotating shafts are engaged in the first slots, preventing the wheel from being rotated.
