Claims

[Scope of utility model registration request]

(1) A housing that can be inserted into and removed from the pipe to be cut, a cylinder that expands and contracts with gas pressure, etc., and a fixed part that is arranged to be able to expand and contract in the radial direction by the cylinder, and the outer periphery of the housing. at least three or more fixing means installed at substantially equal intervals in the circumferential direction, and a hollow rotary shaft supported through the center of the housing so as to be driven and rotated by a variable speed motor built into the housing. a shaft, a nozzle protruding radially from a lower end portion protruding from the housing of the rotary shaft, and a nozzle protection guard removably fixed to the lower end portion of the rotary shaft; A pipe cutting device that injects high-pressure water and abrasive material from the nozzle onto the wall surface of the pipe while fixed inside the pipe to be cut, while the nozzle is movable along the circumferential wall surface of the pipe using a variable speed motor.

(2) The pipe cutting device according to claim 1, wherein the housing is cylindrical and sealed.
