Piezoelectric lighter equipped with a rotatable hook-shaped safety lock is composed of a shank, a finger catch fixed to one end of the shank, a pivot fixed to the other end of the shank, a catch plate fixed to the pivot at the side opposite to the shank and extending substantially perpendicular to the shank, the catch plate having a longitudinal size larger than the width of the slot of a push cap which is put on a piezoelectric unit and a lateral size smaller than the width of the slot of the push cap. The safety lock is rotatably fixed to the top raised side of the casing at such a position that the catch plate may prevent the push cap from descending when the safety lock is put in its locking position in which the shank is vertical with the catch plate laid horizontal and at such a position that the catch plate may allow the push cap to descend when the safety lock is put in its unlocking position in which the shank is horizontal with the catch plate laid vertical. |
