In the field of cutting tools, the cutting of tablets needs to be precise to avoid uneven cutting, resulting in inaccurate dosage, and it is also easy to break into powder, causing excessive loss.

[0003] In the existing technology, the cutting of tablets mainly relies on manual operation, such as using a blade or other cutting tools. There are also some automated cutting devices, such as tablet slicers, but these devices usually can only perform simple straight-line cutting and cannot meet the needs of special populations for tablet dosages. In addition, these devices are also prone to uneven cutting during the cutting process, resulting in inaccurate dosage, and it is also easy to break into powder, causing excessive loss.

[0004] The problems existing in the existing technology in this field are mainly manifested in the following aspects: First, the existing manual cutting or simple automated cutting devices cannot meet the needs of special populations for tablet dosages and are prone to uneven cutting, resulting in inaccurate dosage. Second, during the cutting process of the existing cutting devices, the tablets are easy to break into powder, causing excessive loss and increasing the work difficulty of medical staff. Finally, the design and use of the existing cutting devices are relatively complex and require professional operators, increasing the use cost. Therefore, there is a large room for improvement in the existing technology in this field. Content of the Utility Model
