The steel pipe cutting device, by providing a fixed ring, ventilation grooves, movable grooves, sealing plates, sliding rods, reset springs and fixed blocks, achieves the effect of effectively fixing steel pipes of different diameters when cutting steel pipes, solving the problem that traditional steel pipe cutting devices are not firmly fixed during use and cannot be adjusted and fixed according to the nominal diameter of the steel pipe.

[0004] After analysis, it was found that although the above-mentioned cutting device can process and cut steel pipes of different sizes, when cutting large-sized steel pipes, if the cutting knife cannot complete the cutting in one go, the staff is usually required to rotate the steel pipe to complete the subsequent cutting. However, the clamped steel pipe needs to be loosened before it can be rotated, and then it needs to be clamped again before it can be cut. This operation will delay a lot of processing time and is time-consuming and labor-intensive. Utility Model Content
