A plurality of cleaning rings 10 are arranged around the base 3, and the cleaning ring 10 is movably fitted on the tool holder body 9. The movable block 2 is an existing structure of the lathe body 1, which is used to drive the lathe tool holder to move. The turntable 6 can rotate in the movable block 2, and the turntable 6 can drive the base 3 to rotate through the rotating shaft. A metal brush is arranged on the inner side of the cleaning ring 10 to clean the cutter head on the tool holder body 9, and the tool holder body 9 can slide in the movable groove 13. When the cutter head needs to be switched, the drive motor 4 is started, and the drive motor 4 can drive the transmission through the output shaft The movable gear 5 rotates, and the transmission gear 5 can drive the turntable 6 to rotate through the meshing rack 7. The turntable 6 can drive the base 3 to rotate through the rotating shaft. The rotation of the turntable 6 can drive the tool holder body 9 to move. When the tool holder body 9 drives the fixed rod 11 to slide in the guide groove 8, it can drive the tool holder body 9 to move in the movable groove 13. When the tool holder body 9 moves to the bottom of the base 3, the guide groove 8 will drive the fixed rod 11 and then drive the tool holder body 9 to extend out of the movable groove 13, so that the tool head on the tool holder body 9 can be used. As the base 3 continues to rotate, the guide groove 8 will drive the fixed rod 11 and then drive the tool holder body 9 to retract the movable groove 13, which can prevent the tool head from extending too far out of the base 3, and prevent the unused tool head from hitting the workpiece during processing.

[0031] Specifically, a fixed groove 12 is formed on one side of the movable groove 13 close to the movable block 2 , a fixed rod 11 is movably engaged in the fixed groove 12 , and the fixed rod 11 is welded to the tool holder body 9 .

The driving motor 4 can drive the transmission gear 5 to rotate through the output shaft. The transmission gear 5 can drive the turntable 6 to rotate through the meshing rack 7. The turntable 6 can drive the base 3 to rotate through the rotating shaft. The rotation of the turntable 6 can drive the tool holder body 9 to move. When the tool holder body 9 drives the fixed rod 11 to slide in the guide groove 8, the tool holder body 9 can be driven to move in the movable groove 13. When the tool holder body 9 moves to the bottom of the base 3, the guide groove 8 will drive the fixed rod 11 and then drive the tool holder body 9 to extend out of the movable groove 13, and the cutter head on the tool holder body 9 can be used. As the base 3 continues to rotate, the guide groove 8 will drive the fixed rod 11 and then drive the tool holder body 9 to retract the movable groove 13, which can prevent the cutter head from extending too far out of the base 3, and prevent the cutter head that is not in use from hitting the workpiece during processing. During the retraction of the cutter head, the brush in the cleaning ring 10 can sweep off the debris on the cutter head to clean the cutter head.
