[0002] Steel pipe is a steel material with a hollow cross section, whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it can be divided into round, square, rectangular and special-shaped steel pipes; according to the material, it can be divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the purpose, it can be divided into steel pipes for pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. During the production process, steel pipes need to be cut to a certain length according to demand.

[0003] The prior art proposes a cutting device for steel pipe processing, such as Chinese patent [application number CN202121949686.0], which discloses a base, wherein both sides of the middle part of the top of the base are fixedly connected with reciprocating screws, the tops of the two reciprocating screws are fixedly connected with baffles, and the outer parts of the two reciprocating screws are threadedly connected with nuts, and the outer tops of the two nuts are sleeved with bearings, and the inner rings of the two bearings are respectively fixedly connected with the two nuts; although the patent can drive the cutting wheel to rotate by setting a motor and driving the rotating rod to rotate by the motor, and the rotating rod can also indirectly drive the nut to rotate when it rotates, so that the nut moves outside the reciprocating screw, so that the cutting wheel can reciprocate up and down while rotating, so as to automatically cut the steel pipe; however, the above patent has certain defects during use. For example, in the process of cutting the steel pipe, the above patent controls the cutting wheel to move downward to cut the steel pipe. Some steel pipes have too long diameters. If the steel pipe is not adjusted, it is inconvenient to cut the steel pipe. Utility Model Content
