The middle of the two clamping sliders 14 has opposite threads. An adjusting screw 15 is inserted through the middle of the side of the clamping base 3. A first adjusting handwheel 17 is located at the top of the adjusting screw 15. The two clamping sliders 14 and the adjusting screw 1... 5 is a threaded connection. The distance between the two clamping sliders 14 can be adjusted according to the diameter of the pipe, which has a wide range of applications and improves the support performance of the pipe. The tail end of the cutting table 1 is connected to the mounting frame 5 by bolts. The mounting frame 5 consists of two vertically welded square frames. The vertical part of the mounting frame 5 is slidably connected to the lifting slider 6. The top of the vertical part of the mounting frame 5 is rotatably connected to the lifting screw 23. The top of the lifting screw 23 is welded to the second adjusting handwheel 24. The lifting screw 23 and the lifting slider 6 are threadedly connected. The center of the side of the lifting slider 6 is threadedly connected to the cleaning rod 12. The cleaning rod 12 is equipped with a spiral cleaning blade 13. The cleaning rod 12 is pushed into the waste pipe. The waste pipe is rotated and the spiral cleaning blade 13 is used to clean the waste in the pipe and remove it from the pipe, which is convenient for cutting and safer to use.

[0020] Among them, the vertical part of the mounting frame 5 is provided with guide grooves 25 on both sides, and the lifting slider 6 is provided with sliders that are slidably connected to the guide grooves 25 on both sides, which improves the sliding stability of the slider and improves the cleaning effect of the inside of the pipe. The mounting frame 5 is slidably connected to a collection box 7 on its horizontal part. Support wing plates 28 are provided on both sides of the top of the collection box 7. The mounting frame 5 is symmetrically provided with mounting grooves 26 on its inner side. The mounting grooves 26 are slidably connected to the support wing plates 28. A handle 29 is welded to the back of the collection box 7 to facilitate the collection of garbage and impurities, making it convenient to use. Among them, a guide slope 27 is provided on the horizontal part of the mounting frame 5 near the cutting table 1 to guide the cleaned debris to the center of the horizontal part of the mounting frame 5 and prevent the debris from scattering. Among them, two first guide rods 10 are vertically and symmetrically welded to the top of the cutting machine 4. The first guide rods 10 are slidably connected to the support frame 2 to improve the stability of the cutting machine 4 during cutting and prevent the cutting disc from getting stuck and causing danger. Among them, two second guide rods 16 are symmetrically arranged on the side of the clamping base 3 on both sides of the adjusting screw 15. The second guide rods 16 are slidably connected to the clamping slider 14, and the second guide rods 16 are fixedly connected to the clamping base 3 by the positioning pin 18, which improves the stability of supporting and fixing the pipe. Among them, a reinforcing beam 19 is welded between the four corners of the cutting table 1, and an avoidance groove 21 is provided at the center of the table surface of the cutting table 1. A waste slag box 8 is provided below the avoidance groove 21. The waste slag box 8 is placed on the reinforcing beam 19, which facilitates the collection of cutting debris and is convenient to use. The support frame 2 is fixedly connected to a protective baffle 11 by bolts on the end face of the feed side. The protective baffle 11 is made of transparent acrylic material, which makes it easy to observe the cutting process and makes it safer to use. The support frame 2 is symmetrically provided with mounting threaded holes 20 on the end face of the feed side. Multiple rows of adjustment and positioning holes 22 are symmetrically provided on both sides of the protective baffle 11, which makes it easy to adjust the distance between the bottom of the protective baffle 11 and the table surface of the cutting table 1. It is suitable for pipes of various diameters and has a wide range of applications.

[0021] The working principle of this utility model is as follows: Before use, the distance between the support sliders should be adjusted according to the waste pipe to be cut. Rotating the first adjusting handwheel 17 causes the two clamping sliders 14 to move closer or further apart synchronously, ensuring the waste pipe is stably placed above the clamping sliders 14. During this process, the second guide rod 16 is slidably connected to the clamping sliders 14, improving the stability of the clamping sliders 14. The corresponding positions of the adjusting positioning hole 22 and the mounting threaded hole 20 on the protective baffle 11 are changed, adjusting the distance between the bottom of the protective baffle 11 and the cutting table 1 surface. This ensures the bottom of the protective baffle 11 is close enough to the top of the waste pipe without contacting it, preventing debris and sparks from injuring workers during cutting. Rotating the second adjusting handwheel 24, through the threaded connection between the lifting screw 23 and the lifting slider 6, changes the height of the cleaning rod 12, allowing the cleaning rod 12 to be positioned close to the waste pipe. With the pipes aligned on the same axis, when the pipe size is large, the spiral cleaning blade 13 is replaced with a wider cleaning rod 12 to match the pipe's inner diameter. Before cutting, the worker pushes the waste pipe toward the cleaning rod 12, allowing the cleaning rod 12 to insert into the waste pipe. By rotating the waste pipe set on the support slider, the waste pipe and the cleaning rod 12 rotate relative to each other. During the rotation, the spiral cleaning blade 13 cleans the impurities and rust inside the pipe, and the waste pipe is discharged under the action of the spiral blade 13 and falls into the collection box 7. This effectively avoids unsafe phenomena caused by impurities during the cutting process. After cleaning, the distance between the waste pipe and the cutting machine 4 is adjusted, and the pipe is manually pressed to fix it. The lifting electric push rod 9 is activated, causing the cutting machine 4 to move down to cut the pipe. The cutting debris falls into the waste bin 8 through the clearance groove 21 for easy collection and is more environmentally friendly.
