[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figures 1 to 3As shown, this utility model includes a base 1, and a convex packaging box placement seat 2 is installed on the top of the base 1. The surface of the convex packaging box placement seat 2 can be square, rectangular or circular, and it is configured according to the shape of the actual packaging box.

[0017] A fixed vertical plate 3 is fixedly installed on one side of the top of the base 1. An installation block 4 is fixedly installed on one side of the fixed vertical plate 3. An adjustable movable plate 5 is installed at the bottom of the installation block 4. A pressure plate 6 for pressing and fixing the packaging box is installed at the bottom of the movable plate 5. A perforated tube 7 is fixedly installed in the middle of the movable plate 5. A push rod 8 that penetrates the inside of the perforated tube 7 is fixedly installed in the middle of the bottom of the installation block 4. The push rod 8 is used to push out the waste material generated by punching inside the perforated tube 7. The perforated tube 7 and the push rod 8 are located above the convex packaging box placement seat 2. A stepper motor 9 for adjusting the height of the movable plate 5 is installed on the upper part of one side of the fixed vertical plate 3. A perforation groove 10 aligned with the perforated tube 7 is opened on the top of the convex packaging box placement seat 2. A limiting cylindrical pin 11 flush with the top of the convex packaging box placement seat 2 is fixedly installed inside the perforation groove 10.

[0018] Lifting rods 12 are movably installed through both sides of mounting block 4. Movable plate 5 is fixedly installed between the bottoms of the two lifting rods 12, and a horizontal plate 13 is fixedly installed between the tops of the two lifting rods 12. A horizontal through groove 14 is opened in the middle of the horizontal plate 13. A disc 15 is installed at the output end of stepper motor 9. An eccentric actuating pin 16 is fixedly installed on one side of the disc 15. The eccentric actuating pin 16 is movably installed inside the horizontal through groove 14, thereby effectively driving the movable plate 5 to adjust its height. T-shaped rods 17 are movably installed through both ends of the movable plate 5. A pressure plate 6 is fixedly installed between the bottoms of the two T-shaped rods 17, and compression springs 18 are sleeved on the surface of the two T-shaped rods 17. The two ends of the compression springs 18 are fixedly connected to the movable plate 5 and the pressure plate 6, respectively, thereby effectively installing the pressure plate 6 and effectively pressing and fixing the pressure plate 6. A through hole 19 is opened in the middle of the pressure plate 6, and a punching tube 7 movably passes through the through hole 19, thereby ensuring the effectiveness of the punching.

[0019] When punching holes, the packaging box is placed upside down on the convex packaging box holder 2, and then the stepper motor 9 is started to make the disc 15 rotate once. The rotation of the disc 15 once will drive the eccentric actuating pin 16 to rotate in a circle. The rotation of the eccentric actuating pin 16 will drive the horizontal plate 13 to move up and down once through the horizontal through groove 14. The up and down movement of the horizontal plate 13 will drive the movable plate 5, the pressure plate 6 and the punching tube 7 to move synchronously through the lifting rod 12.

[0020] When the movable plate 5, pressure plate 6 and punch tube 7 move downward, the top rod 8 will move out of the inside of the punch tube 7.
