[0003] At present, when books are bound, they are bound by using a binding machine. During the binding process, for example, a book binding machine proposed in Patent Publication No. CN220198910U uses a plurality of electric push rods to fix the four corners of the book when fixing the book to be bound. During the fixing process, since the moving direction of the electric push rod is fixed, only books of fixed proportions can be fixed. The use is highly limited and books of different proportions cannot be fixed. In addition, the cost is too high by using a plurality of electric push rods.
