Claims

[Scope of utility model registration request]

A clamping tool 33, which is made up of a pair of clamping rods 62 each having a clamping piece or a cutting blade 61 at the tip thereof and rotatably assembled by a pivot 63, is fitted into the tool body 31 so as to be slidable in the axial direction. The operating end 62A of the clamping rod 62 is located in front of the outer opening of the cylinder 32, and the operating end 62A of the clamping rod 62 is inserted into the inclined guide recess 69 of the piston 34 fitted into the cylinder 32.
2A is fitted and engaged, and the piston 34 is inserted into the cylinder 3.
2. In the pneumatic tool in which the clamping tool 33 is operated to clamp by being pushed toward the outer opening 32A by pneumatic pressure, the inner rear end wall 32B of the cylinder 32 has a rear end wall of the tool body 31. The inner end of the sliding guide rod 37 passing through 31A is connected,
A threaded portion 38 is provided on the outer peripheral surface of the outer end of the sliding guide rod 37.
A pneumatic tool characterized in that a cylinder stroke adjustment nut 39 that can freely approach and separate is screwed onto the outer surface of the rear end wall 31A.
