SandPiper“鹬” Nerf Blaster软弹发射器

Here's the break action pistol alike nerf blaster "SandPiper".
Uses 13mm nerf dart. Suitable for indoor target shooting.
Muzzle velocity reaches about 40m/s when using a 1.5*15*150 spring.
Accuracy not bad, I can easily hit a small target at a distance of 5 meters.
This is the first real break barrel blaster I've made, with a ton of experimental structures inside.
I've never get to a real break barrel airgun, so my design inspiration entirely comes from those pictures and videos, my imagination, and a lot of experiments.
Please let me know if you have difficulties assembling it.
The English version AssemblyInstruction will be upload as soon as I finished its translation.

这是中折短手形软弹发射器“鹬”。
发射13mm软弹，适合室内场地打靶玩。
使用1.5*15*150弹簧时，初速约40m/s。
精准度还不错，我可以在5米左右轻松打中小目标。
这是我做的第一把真正意义的中折，它包含了许多实验性的结构。
我从未接触过真正的中折式气枪，所以设计这只玩具的结构完全的依靠图片和视频为参考，还有对着外观猜结构，以及多次的实验。
如果发现装不上欢迎来找我问。
