[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Pipelines need to be laid in the construction of water conservancy projects. When laying pipes, the pipe sizes need to be cut in large quantities. Since the cross-section of the pipe is usually circular and the diameter of the pipe is generally thick, it is particularly inconvenient when it needs to be cut and laid. When ordinary handheld cutting machines cut it, the incision is very uneven and cannot meet the actual use needs, and its cutting efficiency is also very low.

In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, the pipeline is fixed by the cooperation of the lower rotating wheel and the upper rotating wheel, but the range of the concave arc surface of the lower rotating wheel and the upper rotating wheel is limited, and it is not easy to fix large pipelines, which has certain limitations. In addition, the electric cutting knife can only move up and down, and it is not easy to completely cut large pipelines whose diameter is larger than the cutting knife, which is inconvenient to use.

[0005] Therefore, it is necessary to provide a new cutting device for large water conservancy pipelines to solve the above technical problems. Utility Model Content
