Claims

[Scope of utility model registration request]

In the first cylinder chamber formed in the tool body, a piston for advancing and retracting the clamping tool, which is equipped with a clamping tool formed by pivotally supporting the middle part of a pair of clamping rods so as to be openable and closable, is slidably provided, and the piston is slidably mounted on the piston. A piston for opening and closing the clamping tool is slidably provided in the formed second cylinder chamber, and the first cylinder chamber is opened and closed from the outside.
In a pneumatic tool, an air supply path for advancing and retracting the clamping tool that reaches the back surface of the piston in the cylinder chamber is formed in the tool body, and an air supply path for opening and closing the clamping tool that extends from the outside to the back surface of the piston in the second cylinder chamber, The air supply path for opening and closing the clamping tool is formed in the tool body through an air circulation gap formed between the inner surface of the first cylinder and the outer peripheral surface of the piston for advancing and retracting the clamping tool, and extending from the outside to the gap. A pneumatic tool comprising a first air flow passage and a second air flow passage extending from the cavity to the second cylinder chamber and formed in the piston for advancing and retracting the clamping tool.
