Abstract
A rivet gun includes a gun body and a spear detachably connected. The gun body has an axial negative pressure air chamber and an axial hydraulic chamber intercommunicating for gas pressure. The spear includes a connecting chamber communicating with the hydraulic chamber and a gun nozzle. A jaw chamber operating for nail-clamping purposes is adjacent to the gun nozzle. The hydraulic chamber has a piston and an elastic member attached to the piston, other end of the elastic member connecting to the negative pressure air chamber. The piston is coupled to a rod, the rod bears on the jaw chamber to move along the axis of the connecting chamber and thereby clamp on or release a riveting nail.
