Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutters, in particular to a pair of high-stability straight pipe cutting scissors. Background Art

[0002] Pipe shears are a frequently used tool in piping projects. Their primary purpose is to cut pipes into segments for connecting electrical, water, gas, and other pipelines. Electric straight-cutting pipe shears utilize an internal motor and drive mechanism to drive the blades horizontally, shearing the pipe at the cutter head. Existing straight-cutting pipe shears suffer from vibrations when the motor drives the blades, resulting in a certain deviation in the actual blade ejection. When the blades cannot remain completely vertical during pipe cutting, there is a certain risk of blade breakage. Long-term use also inevitably reduces the blade's service life, resulting in a low overall cost-effectiveness. Utility Model Content
