ABSTRACT:
A compact pneumatic hand tool composed of a body, a cylinder assembly, a sealing pad, a striking assembly, a front cap, a control knob, a ventilation cap and threaded bolts. A first bearing is mounted around a rear end of the striking assembly and an outer rim of the first bearing is securely received in a central hole of the cylinder assembly. A second bearing is mounted on a central shaft of the rotor in the cylinder assembly. The control knob is mounted on the cylinder assembly. A front end of the central shaft of the striking assembly extends out of a front cap and the body is connected to the front cap via threaded bolts so that the striking assembly and the cylinder assembly are sealingly enclosed between the front cap and the body to accomplish the compact and light-weight requirements.
