ABSTRACT:
A safety arrangement, which is incorporated with a piezoelectric lighter, includes two axle holders, each having a blocking member, provided on two inner sides of the casing respectively, and an ignition cap including a pivot arm extended downwardly into an ignition cavity of casing and two pivot axles outwardly extended from two sides of the pivot arm into the axle holders respectively so as to pivotally and radially support the ignition cap on the casing wherein the blocking members normally bias against the pivot axles respectively to block up a downward movement of the ignition cap. When the ignition cap is radially slid, the pivot axles are rotatably moved to release the blocking up of the ignition cap with respect to the blocking members respectively, such that the ignition cap is capable of sliding downwardly to depress a piezoelectric unit so as to ignite the piezoelectric lighter.
