The cutting device 6 includes a cutting rail 61 and a cutter 62 mounted on the cutting rail 61, and cuts the steel pipe 02 by the cutter 62. In the process of cutting, since the steel pipe 02 moves forward in a straight direction, if the pipe is cut directly, the cut of the pipe is difficult to coincide with the start and the end, and thus the cutting is difficult to complete, and therefore, the tractor needs to be stopped during normal cutting, and after the tractor is stopped, the welding at the welding position is affected, so that the quality of the whole steel pipe 02 is affected. Therefore, in order to solve the above technical problem, the sliding plate 63 is disposed on the cutting rail 61, so that the sliding plate 63 slides along the cutting rail 61, and the cutter 62 is mounted on the sliding plate 63, at this time, the cutter 62 will move along with the sliding plate 63 during cutting, so that the sliding plate 63 and the steel tube 02 adopt the same sliding speed, and the starting and end positions of the cutting of the steel tube 02 overlap, so that the cutting is smoother, and the cutting is convenient.

As shown in fig. 10 and 11, two stopper rods 631 are provided on the slide plate 63, and the steel pipe 02 passes through the gap between the two stopper rods 631, and the stopper rods 631 allow the steel pipe 02 to be relatively stable at the time of cutting.
