摘要： A blind-rivet gun includes a gun header, a cylinder, a piston, and an air saving device. The cylinder is separated from the gun header. The piston and an inner surface of the cylinder form a seal to divide the cylinder into a first air chamber and a second air chamber. The air saving device includes a switch circuit. The switch circuit turns on a first connection between the air inlet pipe and the first air outlet pipe or turns on a second connection between the air inlet pipe, the second air outlet pipe and the third air outlet pipe. The piston slides in the cylinder to generate inner high pressure by alternatively supplying high pressure air to the first air chamber or the second air chamber. The blind-rivet is pulled in and is pushed out of the blind-rivet ejecting pipe by the inner high pressure.
