[0020] Specifically, the rotating component 8 includes a hydraulic motor 801, a special-shaped plate 802, a hydraulic cylinder 803 and a crank arm 804.

[0026] In the above embodiment, the movable plate is pushed downward by the hydraulic cylinder 1, and the connecting plate pushes the upper connecting plate downward. Since the upper connecting plate, the lower connecting plate, the supporting plate 1 and the supporting plate 2 form a parallelogram, when the upper connecting plate moves downward, the supporting plate 2 will move outward to tighten the inside of the pipe, thereby completing the fixing of the cutting machine inside the pipe.

[0027] In the above embodiment, the crank arm is pulled by starting the second hydraulic cylinder, so that the cutting blade on the crank arm contacts the pipe and cuts it;

[0028] In the above embodiment, a hydraulic rotary joint used in conjunction with the hydraulic cylinder 1 is provided inside the support pipe to avoid the situation where the hydraulic pipe rotates when the hydraulic cylinder 1 rotates, causing the pipe to be entangled and the work cannot be completed normally;

[0029] Working principle: First, put the cutting machine into the pipe until it reaches the part that needs to be cut. Then start the hydraulic cylinder 1 to push the moving plate downward, and the supporting plate 2 to tighten outward to fix the cutting machine inside the pipe. Then start the hydraulic rod 2 to tighten the crank arm so that the cutting blade contacts the pipe for cutting. Start the hydraulic motor 1 to drive the small gear to rotate around the large gear. At the same time, start the hydraulic motor 2 to drive the cutting blade for cutting. When the small gear rotates around the large gear for one circle, the pipe is cut.
