Description
Technical Field
[0001] The utility model relates to the technical field of PVC material cutting equipment, and more specifically to a hand-pressure cutting device used for PVC material processing. Background Art
[0002] PVC material is a material whose main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. It is a synthetic material that is popular and widely used in the world today. Existing PVC materials need to be cut by themselves according to the usage during processing. There are currently three known processing methods: 1. Manual processing using scissors and hand saws. This method has low processing efficiency, uneven fractures and poor precision. 2. Electric toothless saws, circular saws and other cutting methods. This processing method is not convenient for fixing the material during cutting, and the vibration force generated by the electric saw will cause uneven fractures and poor precision. 3. Manual guillotine tool processing. This method uses the principle of leverage. People manually press the guillotine to cut the PVC material and use a ruler to measure the length. It has low efficiency, low precision, uneven fractures, and the blade is easily worn.
[0003] The above-mentioned PVC material cutting methods all have the following drawbacks: it is inconvenient to fix the PVC material, resulting in uneven fractures, which in turn leads to poor precision. In view of this, we propose a hand pressure cutting device. Utility Model Content
