Firestone and back-moving spring, described firestone and back-moving spring are located in groove, and groove is stretched out in the upper end of firestone;
Handle the dead man of lighter valve, what described dead man rotated is arranged on two back-up blocks;
Flint wheel and two is taken turns partially, the radius of described flint wheel is less than two radiuses of partially taking turns, and flint wheel is with two inclined to one side wheel shafts to being connected and can relatively rotating, and two take turns the both sides that are positioned at flint wheel partially, two take turns being arranged on two back-up blocks of rotating partially, and the upper end of described firestone contacts with the bottom of flint wheel; And
The hurricane globe of shaped as frame, described hurricane globe is arranged on erection support, and described flint wheel and two partially wheel is arranged in hurricane globe, and two friction positions of hurricane globe are curved, and two friction positions are approximately higher than two and partially take turns.
The arc at described two friction positions and two is wheel concentric partially, and the arc radius at two friction positions is greater than the radius 0.2-0.6mm of two inclined to one side wheels.
On described two back-up blocks, be equipped with installing hole and lower installing hole, described upper mounting hole site is in the top of lower installing hole; Both sides at described dead man are equipped with installation shaft, and described two installation shaft are located at respectively in twice installing holes also rotatable; Described two, partially on wheel, be equipped with rotating shaft, two rotating shafts are located at respectively on two also rotatable in installing hole.
The utility model advantage is compared with prior art: simple in structure, do not increase the production cost of product, and more than friction is brought up to 4 newton, can reach " CR " regulation.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.At this, it should be noted that, for the explanation of these embodiments, be used for helping to understand the utility model, but do not form restriction of the present utility model.In addition,, in each embodiment of described the utility model, involved technical characterictic just can not interosculate as long as do not form each other conflict.
In the utility model is described, term " on " and orientation or the position relationship of the indication such as D score be based on orientation shown in the drawings or position relationship, it is only the utility model rather than require the utility model with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model for convenience of description.
As shown in Figures 1 to 4, it is the lighter that a kind of children of preventing strike sparks, and comprising:
Be arranged on the erection support 5 on lighter shell, on described erection support 5, be provided with two back-up blocks 52 and groove 51, the both sides that are arranged on groove 51 of described two back-up block 52 symmetries;
Firestone 6 and back-moving spring 7, described firestone 6 and back-moving spring 7 are located in groove 51, and firestone 6 is positioned at the top of back-moving spring 7, and groove 51 is stretched out in the upper end of firestone 6;
