[0034] The working principle of the above embodiments is as follows: Push the conveyor frame 7, insert the positioning plate 8 into the positioning groove 18, and position the fixing rod 28 and the fixing hole 27 on the same center line. Rotate the drive rod 30, and through the threaded connection between the drive rod 30 and the second screw 29 and the sliding connection between the linkage plate 25 and the linkage groove 24, the second screw 29 drives the fixing rod 28 downward through the moving plate 26. The fixing rod 28 is inserted into the fixing hole 27 to fix the positioning plate 8. The pipe is placed inside the mounting frame 3.

Activate the second electric push rod 16, which drives the limiting plate 14 downward. The pipe fits against the limiting plate 14, restricting the pipe. The channel is restricted, thereby resetting the limit plate 14. The drive motor 9 is started, driving the first screw 12 to rotate. Through the threaded connection between the first screw 12 and the sliding plate 10 and the sliding connection between the sliding plate 10 and the sliding groove 13, the first screw 12 drives the mounting frame 3 to move through the sliding plate 10, thereby moving the pipe and adjusting the cutting length of the pipe. After adjustment, the right clamp 11 moves downward to fix the pipe. The pneumatic push rod 15 is started, and the pneumatic push rod 15 drives the cutter 17 downward through the drive plate 19 to cut the pipe. This improves the stability of the drive plate 19. The cut pipe is transported down by the conveyor frame 7 and falls to the ground, minimizing the risk of damage to the pipe from falling from a height.
