ABSTRACT:
A safety device for a utility lighter includes a pusher button slidably mounted on a lighter housing for simultaneously lifting up the gas valve and compressing the piezoelectric unit, a restraining latch transversely extended in the lighter housing, and a safety rotor, which is rotatably connected to the pusher button, having a blocking latch to normally align with the restraining latch to block the upwardly movement of the pusher button for ignition. To ignite the lighter, an adult's thumb has to downwardly rotate the safety rotor to offset the blocking latch with the restraining latch and upwardly push the pusher button in one sequential manner.
