Abstract
The utility model discloses a secure lighter opener for the children, which relates to the technical field of lighter. The opener comprises: a lever, a piezoelectric apparatus, an air vent group and a pressing hand, characterized in that: this opener also comprises a rotary pin that is arranged on the pressing hand and a cam knob that is pivoted on the rotary pin of the pressing hand. The cam knob that is provided with a radial flange downwards supports against the pressure transmitting end of the lever, while the pushing journey of the pressing hand only increases the flange distance (namely the distance between the flange and the axial center is larger than that between the cam edge and the axial center), so the pressure lever of the piezoelectric apparatus can reach the limit position to turn on the air vent valve; the compressed pressure lever of piezoelectric apparatus is restored to enable the cam knob returned to the normal state from the temporary state. Therefore, the utility model has the advantages of reasonable design, safety and reliability, simple structure, good handfeel and convenient use.
