Match gun, also known as chain gun, is a toy firearm made by DIY bicycle parts. Born in China in the 1980s, it uses matchsticks as bullets to make noises. It was once widely circulated in rural China and was an "artifact" in the minds of children born in the 1960s, 1970s, and some born in the 1980s. A number of bicycle chain links are strung on the gun frame made of thick iron wire, and the other hole in the chain link is used for the movement of the gun bolt. The front chain link needs to be driven into a nut on the top of a bicycle spoke to leave a hole the size of a matchstick. The entire chain of chain links and gun bolts are hooped with rubber bands cut from bicycle inner tubes. When using, open the front chain link, insert the matchstick into the hole formed by the nut and pull it out, while the match head The gunpowder remains inside the nut. When the trigger is pulled, the bolt hits the gunpowder at high speed, creating a loud bang and fireworks that give us immense satisfaction.
1. Preparation materials
8-10 sections of bicycle chain, 1 bicycle spoke nut Only, a few rubber bands (or bicycle inner tubes) and an appropriate amount of thick iron wire (slightly thinner than the bicycle chain hole).
2. Tools needed: files, hammers, pliers, nails.
3. Production steps
1. Use a hammer and steel nails to secure the bicycle chain To knock out the chain shaft, you need 8 to 10 links of chain.
2. Take a bicycle spoke nut, file the nut body with a file, and The body diameter should be slightly larger than the chain hole diameter. The nut needs to be rubbed, otherwise the following process will not be completed.
3. Special attention should be paid to this process, too. The key to success or failure is to smash it in firmly. If you feel it is easy to smash it in, then follow the above operations again, because the vibration during launch will make it fall off easily.
4. Use thick iron wire slightly thinner than the chain hole to make the gun body, bolt and trigger as shown in the figure.
5. Assemble as shown below, a matchThe gun is ready.
6. How to load gunpowder.
7. Pull the bolt and pull the trigger. The fatigue and hardship of production disappear without a trace with the crisp sound of gunfire. The grip was made of wire, which shook my hand when firing, so I changed my grip to a wooden one. Finally, I remind children to pay attention to safety, both for themselves and others, and never point guns at others!
