Abstract:
1. A clockwise or counterclockwise rotation control device of a pneumatic tool, installed to a pneumatic tool that uses a pressurized air to drive the operation of a tool and control said tool to produce a clockwise rotation or a counterclockwise rotation, and said pneumatic tool includes a main body, a holding portion coupled to the bottom of said main body, and a pneumatic motor module installed on said main body, and said pressurized air passes through an air incoming passage and enters into said pneumatic motor module to drive said tool to rotate synchronously, and said clockwise or counterclockwise rotation control device comprises: two clockwise or counterclockwise air inlets, disposed on said pneumatic motor module for defining a clockwise rotating state and a counterclockwise rotating state; a rear cover module, disposed on said main body and having an air guide base, and said air guide base includes a containing space interconnected to said air incoming passage and said clockwise or counterclockwise air inlets; and a control valve, installed in said containing space for controlling the flowing direction of said pressurized air and including a valve passage for passing said pressurized air, and the position of said control valve is adjusted to drive said pressurized air to pass through said valve passage to drive said pneumatic motor module for defining a clockwise rotating state and a counterclockwise rotating state.
