Abstract
A safety lighter includes two wheels axles coaxially supported on two sides of a spark wheel respectively. Two driving wheels, each having a receiving cavity provided on an out side of said driving wheel, are supported by two driven bodies of the wheel axles respectively wherein each driving wheel is adapted for turning on the respective driven body in a free rotating manner. Two positioning discs are disposed in the receiving cavities of the two driving wheels and firmly supported by the two driven bodies of the two wheel axles respectively wherein the positioning discs are adapted to hold the two driving wheels in position respectively, so as to prevent lateral movements of the driving wheels with respect to the wheel axles.
