Zusammenfassung:The invention discloses a graphical book. The graphical book comprises a machine body and supporting legs arranged at the bottom of the machine body, travelling rolling wheels capable of sliding are fixedly arranged at the bottoms of the supporting legs, and the axes between the front travelling rolling wheel and the rear travelling rolling wheel are fixedly connected through a linkage shaft rod;and a drilling sliding groove and a concentrated groove are formed in the machine body, the concentrated groove is located right below the drilling sliding groove, and through holes communicating withthe drilling sliding groove are formed in the top end wall of the concentrated groove. According to the graphical book, the whole structure is simple, the design is safe and reasonable, and the manufacturing cost is low; four hole punching punches are used for carrying out punching and drilling machining operation on one graphical book, and drilling is completed at one time, so that the drillingefficiency of the graphical
