[0031] A fixing plate 7 for auxiliary fixation is welded to one side of the mounting plate 21, and an auxiliary plate 22 is welded to the top of the fixing plate 7 at an angle. The other end of the auxiliary plate 22 is welded to the top of the L-shaped support frame 27, and the bottom of the support frame 27 is connected to the other side of the mounting plate 21.

[0032] A nozzle for cooling the pipe during cutting is provided on one side of the mounting block 24. The nozzle is connected to a water tank 5 filled with coolant through a water pipe 6. One end of the nozzle is connected to one end of a telescopic hose 23 that passes through a support frame 27. The other end of the telescopic hose 23 is connected to one end of the water pipe 6.
