Claims

[Scope of utility model registration request]

A round blade tool that incorporates a plurality of round blades into an arbor shaft, and fixes the round blades to the arbor shaft by tightening the round blades in the axial direction of the arbor shaft with a pressing member attached to the arbor shaft at least on one end side of the arbor shaft. The pressing tool has a plurality of cylinders extending in the axial direction of the arbor shaft and arranged to surround the arbor shaft, and an oil chamber is formed in the inner part of each cylinder, and Each oil chamber communicates with each other via a communication passage, and a piston pin is fitted into each cylinder cylinder such that it can freely protrude and retract from one side of the nut body, and on the other side or outer periphery of the nut body, a pressurizing operation member that is movably provided in a pressurizing oil chamber that communicates with the communicating path and increases or decreases the oil pressure in the oil chamber; and a pressure sensing device that communicates with the communicating path and to which the pressure sensing device is removably connected. In a round blade tool provided with a connecting part,
The pressure sensing device connecting portion includes a cylinder portion that communicates with the communication path, and a stopper member that is provided on the outside of the cylinder portion and has a through hole through which one end of a pressure detection rod of the pressure sensing device is inserted. , a piston member that is slidably and liquid-tightly inserted in the axial direction of the cylinder portion on the side of the communication path with respect to the stopper member, and that presses the end face of the pressure detection rod by the pressure in the oil chamber. A round-blade tool that is characterized by
