[0002] Paper straws are best used for drinks that are not too thick and not intended to be drunk for a long time. Paper straws are generally considered more environmentally friendly than plastic straws because they are biodegradable and break down more easily in nature.

[0003] According to Chinese patent CN212421484U, an adjustable quick-cutting device for processing paper straws is disclosed. By pulling the slider inward, the slider drives the cutter to move on the outer surface of the guide rod, making it convenient for the user to adjust the distance between the cutters, thereby facilitating the user to cut straws of different lengths.
