Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cutting, in particular to a pipeline cutting device. Background Art

[0002] Water supply and drainage generally refers to the urban water supply system and drainage system, referred to as water supply and drainage.

[0003] At present, when using the existing municipal water supply and drainage pipe cutting machine, the construction worker needs to hold the pipe with one hand and operate the cutting machine with the other hand. The pipe is easy to shake during operation, which is prone to deviation, resulting in uneven incision. Although there are some cutting devices on the market that can fix the pipe before cutting, they lack the positioning function when fixing the pipe, resulting in the pipe being deflected when fixed. For this reason, we propose a pipe cutting device to avoid such a situation. Utility Model Content
