Safety lock for piezoelectric lighter

A piezoelectric lighter, comprising:

• a lighter casing having an internal fuel chamber for storing liquefied fuel;
• a supporting frame which is supported on a ceiling of said lighter casing having a pusher cavity, an ignition cavity and a pair of supporting walls upwardly extended from two opposite sides of said supporting frame, wherein at least a longitudinal sliding groove is formed on one of said supporting walls;
• an ignition system comprising a gas emitting nozzle, which is received in said ignition cavity of said supporting frame and communicated with said internal fuel chamber of said lighter casing, and a piezoelectric unit disposed in said lighter casing for generating sparks towards said gas emitting nozzle;
• an ignition button which is slidably disposed in said pusher cavity of said supporting frame in such a manner that, when said ignition button is depressed downwardly, said gas emitting nozzle is lifted up to release said fuel and said piezoelectric unit is arranged to generate sparks for igniting said fuel released through said gas emitting nozzle;
• and
• a safety lock, comprising a locking member which is slidably mounted on said ignition button and comprises at least a guiding arm for switching between a locked state and an unlocked state of said piezoelectric lighter, wherein in said locked state, said guiding arm is adapted to bias against a top end of said respective supporting wall for restricting a downward movement of said ignition button, wherein in said unlocked state, said guiding arm is moved forwardly from said locked state and aligned with said sliding groove to enable said guiding arm and said ignition button sliding downwardly when a depressive force is applied to said ignition button.
