[0002] Pencils are the most commonly used writing tools for primary school students, art students, drafters, etc., and mainly consist of three parts: a pencil core, a pen barrel, and a pen barrel coating. During the production of pencils, it is necessary to bundle and clamp the pencil boards to maintain pressure to ensure the bonding effect. In the existing pencil board bundle clamping frame assembly, the pencil boards are placed in the frame, and an external pressurizing device is used to continuously apply pressure to ensure the pressure. In this way, when maintaining pressure on the pencil boards, the frame cannot move, and the pressurizing device needs to continuously apply pressure to the pencil boards for pressure maintenance. Since the pressure maintenance takes a long time, the pressurizing device occupies space and affects subsequent operations. Summary of the Utility Model
