At this time, the pulling plate 8 will displace to both sides, and then the sliding rod 3 will displace with the displacement of the pulling plate 8. Furthermore, the spring 4 will be compressed and rebound. At this time, the triangular block 14 will contact the inside of the docking frame 2 and displace backward under force. Furthermore, the connecting plate 13 will slide into the inside of the installation column 9. At this time, the rotating rod 12 will rotate, and the sliding shaft 11 will slide inside the first sliding groove 10. Finally, with the displacement of the clamping ball 7, it will slide into the inside of the through hole 15. At this time, the spring 4 will rebound, and then the sliding rod 3 will be reset. At this time, the rotating rod 12 can be clamped and fixed by the sliding rod 3, thus completing the installation of the cutting tool head 16. When replacement is needed, just pull the pulling plate 8 to both sides, and the installation column 9 can slide out of the inside of the docking frame 2, and then the quick replacement of the cutting tool head 16 can be completed. By means of the first coating 17 and the second coating 18 outside the cutting tool head 16, the cutting of this tool head can be made smoother and more wear-resistant, and thus the service life of this tool head can be greatly extended.
