Abstract
A pneumatic tool includes an annular space defined between an inner periphery of the space and an outer periphery of the cylinder, the annular space communicates with an adjusting hole. The adjusting hole includes a head, a threaded portion, a contact portion, a shoulder and a communication passage. The adjusting member is threadedly connected to the adjusting hole so that the seal ring is moved with the movement of the adjusting member. A section between the seal ring to the head in the adjusting hole defines an inlet of an escape passage. The seal ring is moved with the adjusting member between two sides of the communication passage so as to control communication between the recess and the escape passage to decide the feature of individual shooting, continuous shooting or high speed shooting.
