This invention relates to a laborsaving lighter, and more particularly relates to a laborsaving and safe lighter, which includes a casing (101), and a piezoelectric assembly and a gas emitting assembly disposed in the casing. The piezoelectric assembly includes a piezoelectric push rod (104) and a button (105). A vertical slot opening (106) is formed in the end face of the button (105), and a safety piece (107) is disposed in the slot opening (106). There is a rock arm (109) between the gas emitting assembly and the safety piece (107). In the lighter's non-operative state, the upper end of the rock arm (109) rests against the lower part (107a) of the safety piece (107). The middle part of the rock arm is contacted with the piezoelectric push rod (104), and the lower end of the rock arm is connected pivotally to the inner surface of the casing (101). According to the principle of lever, the present invention is laborsaving as well as safety. The action of depressing the button is laborsaving and convenient, and the travel path of the button is effectively controlled. It avoids the phenomena of igniting the inflammable gas or gas leakage with by directly depressing the button pressed downward directly or gas leakage due to the button being accidentally pressed, and improves the lighter's safety by the prevention of misoperation and the increase of operation difficulties for children.
