1. the gas ignition device for household electrical appliance, described household electrical appliance have support component, this support component comprises the opening limited by multiple periphery edge, and described gas ignition device has the shell and tightening member that comprise sidewall, and described tightening member comprises:

  • From the base portion that the surface of described sidewall is outstanding;

    The element of a pair elastically deformable, it is connected to described base portion and stretches out from described base portion;

    Each in the element of described a pair elastically deformable comprises the multiple arms be spaced apart from each other, each arm in described multiple arm has the one end being connected to described base portion, and each arm in described multiple arm has the inclination fin extended out from the second end contrary with described one end of described arm;

    Wherein, the element of described a pair elastically deformable is configured such that they can by snap fit in described opening;

    Wherein, described base portion defines single anchor point and has selected width to be applicable to fixing in said opening, thus when described tightening member inserts in described opening, upper surface and the described sidewall of described support component flush, and described inclination fin can engage the periphery edge of described opening, so that described gas ignition device hasp is fixed to described household electrical appliance;

    Wherein, fin described in each comprises multiple tooth in its outer end face, and when described gas ignition device is completely fixed in support component, described multiple tooth engages with the periphery edge of the opening of described support component;

    Thus, the tooth of described fin as the ratchet of periphery edge of opening heading on described support component, thus allows to recover the possible change in size of the opening of the described tightening member, described household electrical appliance and/or the described support component that cause due to coupling tolerance.
