Description

Technical Field

[0002] The Chinese patent, application number 202323283831.8, discloses a convenient cutting device for power pipelines in power construction. The threaded rod is driven to rotate by rotating the handle, so that the threaded sleeve 1 slides on the threaded rod. At this time, the threaded sleeve 1 drives the connecting rod 1 to rotate through the connecting seat. When the connecting rod 1 rotates, it drives the support plate to rise, and then drives the connecting rod 2 to rotate through the support plate, so that the force on the support plate is more balanced. At this time, the threaded sleeve 1 drives the connecting rod 3 to rotate, thereby achieving the effect of supporting the pipeline from the inside through multiple support plates; the motor drives the gear 2 to rotate, and then drives the gear 3 engaged with it to rotate, so that the gear 3 drives the threaded sleeve 2 to rotate, and the threaded sleeve 2 drives the cutting machine to move and adjust the cutting position.
