The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

See also shown in Figure 1ly, the utility model lighter safety ignitor mainly comprises a gland, a push rod 4 and a spring 2, wherein:

The pressing lid is made the branch body structure, includes a pedestal 3 and a lid 1, and pedestal 3 is set on the housing 6 of lighter, can move up and down and drive Piezoelectric switches 7 actions.Have at the top of pressing cage body 3 one with the suitable dimple of lid shape, be provided with two parallel slots 31 and a groove 32 parallel in the dimple with slot, its further groove 32 is used for placing spring 2.Lid 1 is assemblied on the dimple of pedestal 3, and shape and dimple match.The bottom of lid 1 have two pins 11 that protrude downwards and one and pedestal on groove 32 corresponding grooves 12, the pin 11 on the lid is plugged in two slots 31 of pedestal, can be along groove slippage (as Fig. 3, shown in Figure 6).

The upper end of push rod 4 have two with the suitable pin of pedestal slot, pin inserts in the slot of pedestal, and the rear wall that is attached to lid two pins is connected on the pedestal, being driven by lid 1 can be along the groove slippage.The lower end abutment of push rod 4 is on the sheath body 5 of Piezoelectric switches 7, and sheath body 5 is positioned on the housing 6 of lighter, and housing maintains static relatively.Like this because the effect of keeping out between push rod and the sheath body makes the user pressing lid can't be pressed down i.e. akinesia ignition switch.
