Claims

[Scope of utility model registration request]

A round blade tool that incorporates a plurality of round blades into an arbor shaft and tightens the round blades in the axial direction of the arbor shaft using a nut screwed onto the arbor shaft at least on one end side of the arbor shaft to fix the round blades to the arbor shaft, The nut has a plurality of cylinder tubes extending in the direction of the center line of the screw holes on the peripheral edge of the nut body having a screw hole in the center, and an oil chamber is formed in the inner part of each cylinder tube, and The oil chambers communicate with each other through a communication furnace, and a piston pin is fitted into each cylinder so 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 is provided in a pressurizing oil chamber linked to the communication passage so as to be movable forward and backward to increase or decrease the oil pressure in the oil chamber, and is provided between the piston pin and a round blade pressed by the piston pin. is a round-blade tool characterized by having an interposed elastic member.
