Abstract
A barbecue lighter incorporates with a safety arrangement which includes an actuating member including a pusher arm disposed in a trigger cavity of the barbecue lighter in a movable manner, and a resilient element disposed between the pusher arm and an ignition trigger for applying an urging pressure against the pusher arm so as to normally retain the pusher arm in a safety position. In the safety position, the pusher arm is positioned away from a depressible end of a gas lever with a predetermined distance. To ignite the barbecue lighter, the pusher arm is required to move to a position that when the ignition trigger is depressed downwardly, the pusher arm is driven downwardly to depress the depressible end of the gas lever for releasing gas, so as to ignite the barbecue lighter.
