[0034] As an example of this embodiment, the distance between the outer edge 9 of the pressing plate and the second edge 8 of the opening plate 2 is adapted to the width of the packaging box of the box blank to be opened. The pressing plate 3 is slidably mounted on the sliding seat 5 and locked and fixed to the sliding seat 5 by a locking member. The distance between the two sides of the pressing plate 3 and the opening plate 2 is adapted to the width of the bottom surface of the box blank, generally slightly smaller than the width of the bottom surface of the box blank, so that the opening plate 2 and the pressing plate 3 can be smoothly inserted into the box blank. At the same time, the outer edge of the pressing plate 3 inserted into the box blank can be pressed against the bottom surface of the box blank, more preferably against the connection between the bottom surface of the box blank and the other side, to prevent the bottom surface of the box blank from lifting and causing the box blank to shift when the opening plate 2 rotates. The pressing plate 3 is slidably mounted on the sliding seat 5 and locked and fixed by a locking member. This structure ensures that the distance between the pressing plate 3 and the opening plate 2 is adjustable to adapt to box blanks of different widths and sizes.
