Claims

[Scope of utility model registration request]

A first cylinder chamber is formed by removably fixing lids to the front and rear of the cylinder of the tool body, and a piston for advancing and retracting the clamping tool that can be slid back and forth is installed in this cylinder chamber, and the front end of this piston is The middle part of a pair of clamping tools such as a pair of cutters is pivotally connected to be kept open at all times, and the piston is always urged toward the rear lid body by a return spring or the like, so that the piston between the rear lid body and the rear part of the piston is The first cylinder chamber and the port provided in the rear lid body are communicated through an air supply path for advancing and retracting the clamping tool, and a piston for opening and closing the clamping tool is installed in the second cylinder chamber formed in the piston, and the second cylinder chamber is provided with a piston for opening and closing the clamping tool. The piston is always urged toward the plug provided at the rear of the second cylinder chamber by a return spring or the like, and the second cylinder chamber and the port provided in the rear lid are connected between the plug and the rear of the second piston. In a pneumatic tool that communicates with an air supply path for opening and closing the clamping tool, a screw having a stepped portion at the tip is formed on the outer periphery of the intermediate portion of the first piston, and an adjusting cylinder is screwed onto the screw. A pneumatic tool characterized in that the tip of the adjustment cylinder can be moved forward and backward in front of the step by rotation of the pneumatic tool.
