What is a pick?

Air pick is a common saying in some places. The correct name is: pneumatic pick, which is a pneumatic tool. Pneumatic pickaxe is a kind of portable equipment which uses compressed air to repeatedly hit pickaxes through pistons to cut mountains, build roads and mine. The pneumatic pick consists of impact mechanism, gas distribution mechanism, pick drill and other parts. When working, the impact hammer repeatedly moves along the cylinder in the impact mechanism to impact, and when the pick is propped on the construction surface, the purpose of crushing can be achieved. Pneumatic picks are easy to use and carry, and can often be seen on construction sites.
