Problems solved by technology

[0002] At present, in the process of plate production, it is often necessary to cut some iron sheets. The existing scissors not only have limited shearing force, but cannot cut thicker iron sheets. , during the cutting process, workers must be close to the iron sheet, but some iron sheets are often large in size and must be laid on the ground for cutting. At this time, when using these ordinary scissors for cutting, the worker must bend down or Kneeling and standing on the metal surface will not only make the operator feel uncomfortable, but at the same time, the labor intensity will be greater
