Technique of thrilling through fire lighter for firecracker

Abstract

A direct-through technique of lead wire on sparkler includes sticking a numbers of sparkler cylinders together to form positive polygonal set body of sparkler, opening hole and setting lead wire then pushing up said lead wire in cylinder to be convex form, packing soil and using press shaft with concave center to press soil tightly, exposing top of convex form lead wire of sparkler above soil surface and contacting said lead wire with gunpowder to be packed late on.

Description

technical field [0001] The invention belongs to a firework piercing technology, in particular to a firework piercing technology. Background technique [0002] There are two main types of traditional firework piercing techniques: one is to tamp the soil in the lower part of the firework barrel, and then use a long needle with a firework lead wire to pass through the shell of the firework barrel arranged in rows above the soil in the barrel. Then use a crochet needle to penetrate the barrel between the two needle holes of the fireworks barrel, hook the middle part of the lead wire of the fireworks out of the barrel, and finally fill the barrel with fireworks powder; the second is to directly use a crochet needle to pass through the barrel from the outer end of each fireworks barrel in turn The other end of the body hooks the firecracker lead wire outside the cylinder, hooks the firecracker lead wire into the cylinder body through the second needle eye ...

AI Technical Summary

Problems solved by technology

The disadvantages of the above two kinds of firecracker threading techniques: first, the operation is very troublesome, slow, and low in efficiency; If the gap between the needle eye and the lead wire is too large, the powder of the fireworks will leak, which will easily cause the surrounding fireworks to catch fire, and the safety factor is poor; the fourth is that the gap time between the two fireworks is not easy to adjust.
