Two, easily get loose and service life short: because of this commonly uses inner end 14 block 11 of protrusion on the embedding system ignition switch 10 from the side of the safety switch of burning torch, make it have the function that ignition switch of preventing 10 is started easily, yet because this block 11 is subjected to the restriction of burning torch volume can only make the less projection of a shape with slide block 13 inner ends 14.Therefore, when assembling, must very accurately can make 14 embeddings of slide block 13 inner ends built in block 11 positions; Again because block 11 mainly is to utilize slide block 13 inside portions 14 from the side with its embedding system, so after firmly pushing ignition switch 10 or using a period of time, slide block 13 inner ends 14 just are easy to produce the no longer blocking that gets loose with block 11, or the damage of bursting apart, make it lose the effect of mutual embedding system.

The purpose of this utility model is to provide a kind of need promotion safety knobs to be moved to an appropriate location, and interlock disengaging ignition switch can take place, and assembles the safety switch of simple and safe burning torch.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of burning torch safety switch, it mainly is a safety knobs and a location to be set above ignition switch one end in burning torch collude and wait the member composition, wherein safety knobs is slidingly installed in the burning torch top, the bottom then wears to burning torch inside, and also be provided with an elastomer in the safety knobs, elastomeric other end contact is on the burning torch housing, the location is colluded and then is hubbed between safety knobs and the ignition switch, the one end is provided with one and is the hook portion of colluding shape, hook is on the fitting portion of safety switch one end, and the other end one skew back is to extending a lug, and the location is colluded and also is provided with a flexible member in addition.

Because the utility model adopts the said structure design, it has following advantage in concrete enforcement:

One, security is preferable: because the safety switch of the burning torch that the utility model adopted, must earlier safety knobs passing can be pushed ignition switch again to position, a location lights a fire it, and owing to be provided with an elastomer in this safety knobs, when pushing ignition switch, its safety knobs also can not be decontroled, therefore push action safety knobs and ignition switch can be lighted a fire it simultaneously, thereby can avoid stirring unlatching because of normal children's curiosity, again because safety knobs all keeps open and-shut mode at ordinary times, so also can therefore avoid because of pushing because of carelessness its unlatching, hence one can see that, and its security is preferable.

Two, be difficult for getting loose and long service life: mainly make a hook or separating action because of the safety switch of burning torch of the present utility model, reach the action of embedding system ignition switch by the fitting portion that corresponding ignition switch front end is colluded in a location that is hubbed on ignition switch front end top.Therefore, the restriction that is not subjected to the burning torch volume with the fitting portion of ignition switch is colluded in the location, can be made into a bigger volume, when assembling, the location is colluded cooperate embedding built in the fitting portion place, and the location is colluded with the contact area of the fitting portion of ignition switch also big than what commonly use, even so after firmly pushing ignition switch or using a period of time, the hook portion that collude its location and the fitting portion of ignition switch can not get loose no longer blocking yet or the situation about damaging of bursting apart takes place, thereby have increased its service life.
