the self-locking switch is electrically connected with the time delay circuit board, the time delay circuit board is electrically connected with the frequency conversion boosting circuit board, the frequency conversion boosting circuit board is electrically connected with the high-voltage coil, and the high-voltage coil is connected to the metal electrode through a lead.

The telescopic firework igniter is characterized in that a pressing rod of the self-locking switch is fixed with a metal lever, and the metal lever presses a liquefied gas control valve of the liquefied gas storage bin.

The telescopic firework igniter is characterized in that two copper sheets which are arranged in parallel are fixed in the shell, a spring is arranged on one of the copper sheets, a dry battery is clamped between the two copper sheets, and the dry battery is electrically connected with the self-locking switch.

The telescopic firework igniter is characterized in that an insulating rubber ring is fixed between the shell and the extension pipe.

The metal electrodes of the telescopic firework igniter are fixed in the extension pipe through the insulating rubber rings.

The telescopic firework igniter is characterized in that the end part of the extension pipe is provided with a windproof cover.

Has the advantages that:

1. the utility model discloses a self-locking switch, switch not only switch on the circuit after pressing down, push down the metal lever moreover and open liquefied gas control valve, guarantee the sustained release of liquefied gas and the production of electronic pulse lasts.

The utility model discloses a delay circuit, 5 seconds of time delay guarantee some firearm and open the back, can not produce the naked light immediately.

The utility model discloses a shell all-metal design guarantees the tightness of some firearm after setting off fireworks.

The utility model discloses a windshield design guarantees flame burning, lights the lead wire.

The utility model discloses set up the extension pipe, the action bars can prolong when needing, and the operating point is in the personnel's of setting off hand, and some firearms can contract when not needing at the another of telescopic link, conveniently carries. And electronic ignition and nameless ignition operation are realized.
