[Prior Art] Pneumatic nail grab is a hand tool that uses a high-pressure air as a power source to drive a nailing operation. Generally speaking, the gun body is provided with a pushable safety slider for controlling the nailing and operation sequence, and the gun body is provided with a plurality of main air chambers for continuously collecting high dust air to maintain a certain pressure. a cylinder, a piston grouping one piston in the cylinder, a nailing rod integrally connected to one of the bottom ends of the piston, a trigger valve for driving the nailing rod, and the like. The piston system divides the cylinder into a top cylinder chamber and an underlying cylinder chamber. The top cylinder chamber communicates with an exhaust outlet on one of the bodies, and the bottom cylinder chamber communicates with an exhaust outlet of the gun body. The user can push the safety slider on the object to be nailed and press the ® trigger valve to switch the driving air path of the high-pressure air in the gun body, so that the high-pressure air enters the top cylinder chamber through the driving air passage to drive the piston.
