The driving mechanism 2 is provided with a disassembly and assembly buckle 1. The disassembly and assembly buckle 1 includes a plurality of locking posts 11. A circular limiting plate 12 is fixedly connected to the front of the locking posts 11. A cylinder 13 is fixedly connected to the front of the circular limiting plate 12. A spring 14 is fixedly connected to the front of the circular limiting plate 12 around the outer side of the cylinder 13. A connecting plate 15 is fixedly connected to the front of the plurality of cylinders 13. A handle 16 is fixedly connected to the front of the connecting plate 15. The driving mechanism 2 is slidably connected to the outer wall of the locking posts 11. The driving mechanism 2 includes two cylinders 21. A pressure block 22 is fixedly connected to the output end of the two cylinders 21. A square insertion groove 23 is opened below the pressure block 22. A plurality of circular fixing blocks 24 are fixedly connected to the front of the pressure block 22. The front of the inner wall of the square insertion groove 23 is... A plurality of T-shaped circular grooves 25, corresponding to a plurality of locking posts 11, are provided through the interior of the circular fixing block 24. A circular hole 26 is provided in front of the inner wall of the T-shaped circular groove 25. The inner wall of the T-shaped circular groove 25 is slidably connected to the locking posts 11 and the outer wall of the circular limiting plate 12. The inner wall of the T-shaped circular groove 25 is fixedly connected to the other end of the spring 14. The inner wall of the circular hole 26 is slidably connected to the outer wall of the cylinder 13. A first cutter 3 is slidably connected to the inner wall of the square insertion groove 23. The first cutter 3 includes a second cutter 31. A square insertion block 32 is fixedly connected above the second cutter 31.
