[0002] Nowadays, more and more outdoor sports enthusiasts like thrilling outdoor activities. Although they have made sufficient preparations and risk plans before setting off, sometimes they will inevitably encounter some emergencies. In this case, it is necessary to send a distress signal to the outside world for self-rescue or to facilitate rescue. Because domestic signal flares are firearms and ammunition, ordinary outdoor sports personnel cannot buy them. Although conventional fireworks have the characteristics of signal flares, ordinary fireworks are not fast, such as not having the conditions for ignition or having difficulty in rapid ignition, and fireworks are used to signal for help, so the launch direction and trajectory need to be controlled to a certain extent. Utility Model Content

[0003] The utility model is to solve the problem of fireworks being used for outdoor distress signals, and proposes a handheld fireworks signal transmitter, which can realize the rapid installation and ignition of fireworks and the non-delayed launch. The performance of the emitted colored smoke fireworks signal is close to the effect of a signal flare.
