When the two pushing and pulling transmission blocks move away from each other, they will drive the two moving limit plates to move outside the two openings. Immediately afterwards, the operator starts the driving motor to rotate in the reverse direction. When the driving motor rotates in the reverse direction, it drives the transmission threaded sleeve to move inwards through the transmission threaded rod. When the transmission threaded sleeve moves inwards, it drives the moving mounting head to move inwards. When the moving mounting head moves, it drives the positioning slider to slide along the inside of the positioning chute through the fixed connection bar, increasing the stability of the moving mounting head during movement. When the moving mounting head moves inwards, it will drive the cutting tool to be pressed against the friction pad ring through the two moving limit plates for fixation, thus quickly completing the installation; enabling the present cutting tool to be quickly disassembled and assembled, making the tool replacement very convenient.

[0020] During disassembly, the operator starts the forward operation of the quick disassembly and assembly component. When the quick disassembly and assembly component operates forward, the limit on the cutting tool will be released. Then the operator quickly removes the cutting tool from the moving mounting head 5 to complete the disassembly; during installation, the operator sleeves the cutting tool onto the surface of the moving mounting head 5. Then the operator starts the reverse operation of the quick disassembly and assembly component. When the quick disassembly and assembly component operates in reverse, the cutting tool will be pressed against the friction pad ring 4 for fixation, so as to quickly complete the installation; enabling the cutting tool of the present utility model to be quickly disassembled and assembled, making the tool replacement very convenient.

[0021] The quick disassembly and assembly component includes a driving motor 8, two positioning sliding grooves 13 and a driving cylinder 14. The driving motor 8 is fixedly installed inside the installation groove 7. The two positioning sliding grooves 13 are symmetrically formed on the inner wall of the device main body 1. The driving cylinder 14 is fixedly installed on the inner wall of one end of the movable mounting head 5. The output end of the driving motor 8 is fixedly installed with a transmission threaded rod 9. The transmission end of the driving cylinder 14 is fixedly installed with a pushing transmission block 15; a transmission threaded sleeve 10 is threadedly connected to the surface of the transmission threaded rod 9. One end of the transmission threaded sleeve 10 away from the driving motor 8 is fixedly connected to one end of the movable mounting head 5. On both inclined surfaces of one end of the pushing transmission block 15 away from the driving cylinder 14, there are closely attached push-pull transmission blocks 18; two fixed connection bars 11 are symmetrically installed on the surface of the movable mounting head 5. On the sides of the two fixed connection bars 11 away from each other, there are fixedly installed positioning sliders 12. The two positioning sliders 12 are installed inside the two positioning sliding grooves 13; one end of the pushing transmission block 15 away from the driving cylinder 14 is fixedly installed with a fixed connection block 16.

When the V-shaped transmission bar 17 moves, it will drive the two push-pull transmission blocks 18 to move towards each other. When the two push-pull transmission blocks 18 move towards each other, they will drive the two movable limit plates 19 to move into the interiors of the two openings 6 and retract, thus releasing the limit on the cutting tool, enabling the operator to conveniently remove the cutting tool for replacement;

[0023] During installation, the operator slips the cutting tool onto the surface of the movable mounting head 5. Then, the operator activates the driving cylinder 14 to extend and push the extrusion transmission block 15 to move. When the extrusion transmission block 15 moves, it will push the two push-pull transmission blocks 18 to move away from each other. The movement of the two push-pull transmission blocks 18 away from each other will drive the two movable limit plates 19 to move to the outside of the two openings 6. Immediately afterwards, the operator activates the driving motor 8 to run in reverse. When the driving motor 8 runs in reverse, it drives the transmission threaded sleeve 10 to move inward through the transmission threaded rod 9. When the transmission threaded sleeve 10 moves inward, it drives the movable mounting head 5 to move inward. When the movable mounting head 5 moves, it drives the positioning slider 12 to slide along the inside of the positioning chute 13 through the fixed connection bar 11, which increases the stability of the movable mounting head 5 during movement. When the movable mounting head 5 moves inward, it drives the cutting tool to be pressed against the friction pad ring 4 for fixation through the two movable limit plates 19, thus quickly completing the installation.
