It aims to make the finished products uniform in size and have smooth edges through precise cutting, thereby improving the quality and aesthetics of printed materials. Its core technology lies in efficiently and accurately completing batch cutting tasks, while adapting to the needs of printed materials of different thicknesses, sizes and materials.

[0003] The connecting plate is one of the key components of a book trimmer. Its main function is to firmly hold the book down during the trimming process, preventing it from shifting and ensuring trimming accuracy and stability. Connecting plates are typically designed based on the book's size, thickness, and binding style to accommodate different types of book trimming needs. Therefore, the adaptability of the connecting plate is crucial for the normal operation and trimming quality of the book trimmer. Replacing the connecting plate on traditional book trimmers is usually cumbersome, requiring operators to use tools to remove the old connecting plate and install the new one. This process is not only time-consuming and labor-intensive but also demands a high level of skill from the operator, easily leading to problems such as insecure installation and inaccurate positioning, affecting the normal use of the book trimmer.

[0004] Chinese invention patent CN117245716, entitled "A Quick Loading and Unloading Pressing Device for a Three-Sided Book Cutter," mentions a structure that allows for quick replacement of the pressing plate.
