Description

Technical Field

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

[0002] When carrying out water conservancy project construction, the pipes delivered are often of a specific length. The length of the specific pipe is difficult to meet the actual water conservancy project construction, so the pipe needs to be cut to divide a long pipe into multiple short pipes.

[0003] Although the existing device can realize the positioning of the pipe fitting, when the length of the pipe fitting is much longer than the length of the workbench, the protruding part of the pipe fitting will be suspended in the air. Under the influence of the pipe fitting's own gravity, the suspended part will droop, which will easily cause a slight tilt during cutting. Utility Model Content
