Abstract
A hand-held pressing apparatus comprises a pressing assembly and a controlling valve. The pressing assembly comprises a piston cylinder, a piston, a piston rod mounted on the piston, and a tool. The piston cylinder defines a piston chamber. The piston is slidably received in the piston chamber. The piston rod is partially protrudes from the piston chamber. The tool is mounted to the protruding end of the piston rod. The controlling valve connects to a pressure source, and is for controlling the gas pressure in the piston chamber. When the pressing head aims at the workpiece, the controlling valve controls the piston chamber to pressurize the pressure cylinder assembly using pressurized gas from the pressure source, to drive the piston, the push rod and the tool to act on the workpiece.
