置。A popular control device for pneumatic impact tools in which the air passage that sends compressed air to the impact unit of the tool body is opened and closed by a throttle shaft inserted into the tool body, and an operating lever is provided at the end of the throttle shaft. One end is fixed to the front side of the operating lever, the middle part extends along the operating lever, and the other end passes through a guide hole formed at the base of the operating lever to attach the tool to the lever. A hook lever made of a spring that faces the surface of the main body and is constantly pressed against the nuclear surface.
A recess is formed in at least a portion of the surface of the tool body that corresponds to the air-blocking position of the throttle shaft on which the other end of the hook lever slides. A popular control device for a pneumatic impact tool, characterized in that the engagement between the and the recess is released.
