[0002] In the production process of books, notebooks and other paper products, when they are assembled into a form, the side margin needs to be cut and trimmed. For example, a book trimming device disclosed in Chinese patent application (application number 202322699146.7) includes a paper channel and a book cutting structure. The book cutting structure includes an upper cutter, a lower cutter and a side guard cutter. The upper cutter is arranged above the paper channel, the lower cutter is arranged below the paper channel, and the side guard cutter is arranged on the top of the lower cutter. When cutting, one end of the side guard cutter contacts the spine. However, since books or notebooks are made of multiple stacked paper sheets, and in order to facilitate cutting, there is usually a certain angle between the cutter and the paper sheet. When the upper cutter cuts down, the cutter will form a certain displacement with the paper sheet, which will cause the paper sheet to slip, affecting the cutting accuracy, causing burrs on the edge of the book or notebook and affecting the flatness. In addition, since the strength of the spine side of the book or notebook is greater, the vertical cutting of the upper cutter directly damages the spine. SUMMARY
