Advantages of Pneumatic Wrench

Pneumatic wrench, also known as ratchet hand and electric tool assembly, is mainly a tool to provide high torque output with minimum consumption. It accelerates the rotation of an object with a certain mass through a continuous power source, and then collides with the output axis instantaneously, so that a relatively large output of torque [...]
