Description

Technical Field

[0001] The utility model relates to the field of pipeline production, and more specifically, to a pipeline cutting device. Background Art

[0002] During the construction process, pipes are often used to construct the waterways or circuits of the entire building. Therefore, pipes are used in large quantities in construction. Before the pipes are used, the length of the pipes needs to be adjusted to the required length or the pipes need to be cut open for use. Therefore, a pipe cutting device is needed to cut the pipes. Existing pipe cutting devices lack a fixed structure and are generally only moved by operating a handheld cutting saw to cut the pipes. Since the pipes are circular structures, the pipes are easily displaced due to force during the cutting process, thereby affecting the cutting quality of the pipes and the smooth cutting of the pipes. Moreover, when the diameter of the pipes is too large, the pipes cannot be cut open in a single cut. It is not easy to change the positions of different surfaces of the pipes manually, which makes it inconvenient to cut other surfaces of the pipes, thereby affecting the smooth cutting of the pipes.
