Abstract

A dislocation-type safety lighter the invention is disclosed. The dislocation-type safety lighter includes a main body, a wheel racket, a file wheel, a metal cap, and a lever. The lever includes a pressing part, a base, and a slipping hole. Each side of the base furnishes a salient part used to be the pivot point C of the lever. The salient parts are fitted in the securing holes near the bottom of the file-wheel seats, and the securing holes) are used as pivot seat for bearing the salient parts. The metal cap is capped on the top of the wheel racket to cover the file wheel and the lever. The height H between the elevation of the 'point A' of exerting force P and the elevation of the pivot point C is in the range (1/3)H'*H*(2/3)H' where the height H' is equal to the diameter of the file wheel (3). The larger the height H, the more laborious it is to turn the file wheel (3) by the thumb of the user that makes the children whose exerting force is relatively weak harder to ignite the lighter. In this way, the lighter of the invention is capable of improving the efficacy of safety usage. Nevertheless, the exerting force P is still within the range of an adult user.
