[0028] Moving mechanism, the moving mechanism is arranged on the outer surface of the round rod 6;

[0029] Among them, the moving mechanism includes a short tube 7, the inside of the short tube 7 is movably sleeved with the outer surface of the round rod 6, the left side of the outer surface of the short tube 7 is fixedly installed with a first hinge block 8, the inside of the first hinge block 8 is hinged with a moving rod 9, the other end of the moving rod 9 is hinged with a second hinge block 10, the outer surface of the second hinge block 10 is movably connected to the inside of the limiting groove 5, the left side of the second hinge block 10 is fixedly installed with a moving block 11, the outer surface of the moving block 11 is movably connected to the inside of the round block 4, and the left side of the moving block 11 is movably connected to the right side of the spiral cutter shaft body 2.

[0030] When the short tube 7 drives the eight first hinge blocks 8 to move to the left, at this time, the eight first hinge blocks 8 will drive the eight second hinge blocks 10 to move through the eight moving rods 9. Due to the limiting effect of the eight limiting grooves 5, at this time, the eight second hinge blocks 10 will drive the eight moving blocks 11 to move out of the round block 4.

[0031] Among them, a threaded rod 12 is fixedly installed on the right side of the round rod 6. A ring 16 is fixedly sleeved on the outer surface of the threaded rod 12. A rotating ring 13 is movably connected to the left side of the ring 16. The inner part of the rotating ring 13 is threadedly sleeved on the outer surface of the threaded rod 12.

[0032] Due to the design of the ring 16, it will play a blocking role in the movement of the rotating ring 13. Since the rotating ring 13 is threadedly sleeved on the outer surface of the threaded rod 12, when the rotating ring 13 rotates, it will move to the left.

[0033] Among them, a long tube 14 is fixedly installed on the left side of the rotating ring 13. A moving ring 15 is movably sleeved on the outer surface of the left side of the long tube 14. The right side of the moving ring 15 is movably connected to the left side of the threaded rod 12. The inner part of the moving ring 15 is fixedly sleeved on the outer surface of the short tube 7.

[0034] When the rotating ring 13 drives the long tube 14 to rotate and move to the left at the same time, at this time, the left side of the long tube 14 will drive the moving ring 15 to move to the left. At this time, the short tube 7 will be driven by the moving ring 15 to move to the left.

[0035] Among them, a fixed ring 17 is fixedly installed on the left side of the spiral tool shaft body 2. The right side of the fixed ring 17 is movably connected to the left side of the blade 3.

[0036] Due to the design of the fixed ring 17, it will play a blocking role in the blade 3.

[0037] Among them, a fixed block 18 is fixedly installed on the left side of the main shaft 1. A short rod 19 is movably sleeved inside the fixed block 18. A gear 20 is fixedly sleeved on the outer surface of the left side of the short rod 19.

[0038] Since the short rod 19 is movably sleeved inside the fixed block 18, the short rod 19 can be taken out from inside the fixed block 18.

[0039] Among them, a fixed frame 21 is fixedly installed on the right side of the top of the fixed block 18. A square rod 22 is movably sleeved inside the top of the fixed frame 21. The bottom end of the square rod 22 passes through the top end of the fixed block 18 and extends into the inside of the top end of the short rod 19.

[0040] Due to the limiting effect inside the top of the fixed frame 21, the square rod 22 can only move up and down. When the bottom end of the square rod 22 is inside the top end of the short rod 19, at this time, the square rod 22 will play a locking role in the short rod 19.

[0041] Among them, a lifting block 23 is fixedly sleeved on the outer surface of the square rod 22. A spring 24 is fixedly installed on the top end of the lifting block 23. The top end of the spring 24 is fixedly connected to the outer surface of the fixed frame 21.

[0042] Due to the elastic force of the spring 24, it has a good reset effect on the movement of the square rod 22 and the lifting block 23.

[0043] The working principle and usage process of the present utility model are as follows:

[0044] First, the operator withdraws the damaged blade 3 from the inside of the spiral cutter shaft body 2, and then inserts a brand-new blade 3 into the inside of the spiral cutter shaft body 2. Subsequently, the operator turns the rotating ring 13 to make the rotating ring 13 rotate. Since the rotating ring 13 is threadedly sleeved with the threaded rod 12, at this time, the rotating ring 13 will move to the left while rotating. At the same time, the long tube 14 will rotate and move to the left under the drive of the rotating ring 13. At this time, the left end of the long tube 14 will drive the moving ring 15 to move to the left. Then, the short tube 7 will move to the left under the drive of the moving ring 15. At this time, the eight first hinge blocks 8 will move to the left under the drive of the short tube 7. Subsequently, the eight first hinge blocks 8 will respectively drive the eight moving rods 9 to move. At this time, the other ends of the eight moving rods 9 will respectively drive the eight second hinge blocks 10 to move. Due to the design inside the eight limit slots 5, the movement of the eight second hinge blocks 10 will be limited. At this time, the eight second hinge blocks 10 will move outward simultaneously under the drive of the eight moving rods 9. At this time, the eight moving blocks 11 will move outward of the round block 4 under the drive of the eight second hinge blocks 10. Then, the left sides of the eight moving blocks 11 will be in contact with the right sides of the eight blades ights of the eight blades 3 during the movement, thus playing a good blocking role in the movement of the blade 3, and further realizing the function of facilitating the disassembly and installation of the blade 3.

[0045] Subsequently, the operator moves the square rod 22 by pulling the lifting block 23. Due to the design inside the top of the fixed frame 21, the movement of the square rod 22 will be limited so that it can only move up and down. At this time, the lifting block 23 will drive the square rod 22 to move upward. At this time, the spring 24 will be in a compressed state. When the bottom end of the square rod 22 moves above the top end of the short rod 19, the operator can replace the short rod 19 at this time. Then, the operator releases the lifting block 23. Due to the elastic force of the spring 24, at this time, the spring 24 will drive the square rod 22 to move downward through the lifting block 23 for reset. At this time, the bottom end of the square rod 22 will be movably sleeved inside the top end of the short rod 19, thus playing a good locking effect on the short rod 19, and further realizing the function of facilitating the installation and disassembly of the short rod 19.
