A child resistant lighter has a handle, a barrel, a fuel tank, a gas release nozzle, a piezoelectric unit, an ignition means, a lever, a flame nozzle, a fuel conveying hose connecting the flame nozzle and the gas release nozzle, and a safe means having a slidable button, a pivot, an arm rotatably mounted on the pivot and having a hole surrounding the transmission pole, and a second spring. The ignition means further has a transmission pole, a first spring, a first protrusion, and a second protrusion. One end of the transmission pole connects to the lever and the other end thereof meets the triggering button of the piezoelectric unit.
