Abstract

A safety lighter for cigarette is improved based on the original outer shell, a press apparatus, a press hand and a raise plate. A push plate is arranged above the press hand and can move outward corresponding to the press hand in horizontal direction. A spring is arranged inside the press hand to keep the push plate in resetting trend inward. A block piece is arranged in the inner surface of the push plate to match with the other end of the raise plate. When the press hand is in an upward resetting state after lighted and the push plate is in the natural state, the outer side of the other end of the raise plate is against with the block piece. The structure is adopted, therefore, the other end of the raise plate hinders the downward movement of the press hand, thereby effectively preventing accident lighting. The push plate must be pushed outward relating to the push hand in use, therefore, the raise plate moves away from the clip slot of the block piece, thereby removing the limit to the raise plate. The press hand is pressed down to realize lighting. The lighting action is completed by one finger in sequence, therefore, the child of weak coordinated capability is hard to imitate, thereby reaching safe use.
