PNEUMATIC TOOL

摘要

A pneumatic tool with a simple structure. The tool has a tubular housing (50), a stationary shaft (52), a first piston (56) slidable along the stationary shaft, a second piston (58), a tool installation member (60) drivingly connected to the second piston, a compressed air supply path (70) passing through the stationary shaft and supplying compressed air between the first and second pistons, and an air discharge path (76) for discharging the compressed air, supplied between the first and second pistons, to the outside of the housing when the first and second pistons are separated by a predetermined interval. The compressed air supply path has an axial section (70a) in the stationary shaft and a radial section (70b), a compressed air inlet recess (70c) in the inner wall surface of a shaft sliding hole, and a supply outlet (70d) extending forward from the forward end of the compressed air inlet recess and communicating with a portion between the first and second pistons.
