1. When compressed air is introduced into the front port of the cylinder, the clamping action is performed. That is, first rotate the piston rod and cross arm 90° and then Workpiece clamping. When compressed air is introduced into the rear air port, it is released, that is, the piston and cross arm are released from the workpiece, and then the piston rod and cross arm rotate 90° in the opposite direction to facilitate assembly and disassembly of the workpiece.
