7. The shell is square and cylindrical, can be directly attached to the fireworks by methods of pasting, bundling and the like, is stably connected, and ensures the reliable operation of the device.
8. Through set up the water barrier on the surface at the lead wire, avoid under the circumstances such as slope, mistake set off in the fireworks handling, lead to the lead wire to be soaked by the fire retardant liquid, even if change also can't normally ignite for the circumstances of correct set off mode.
9. The paraffin is arranged as a water-resisting layer, the paraffin can play a role in preventing wetting and can be burnt out along with the lead, and after the water-resisting layer is burnt out, the side of the lead cannot be burnt in the flame retardant liquid.
10. By arranging at least two leads, one lead is lost after one-time wrong setting off, and the fireworks can still be ignited by other leads after the correct setting off mode is changed.
