Further, the tool post is arranged on the left side of the machine tool spindle.

Further, a pushing device is provided on the right side of the main shaft of the machine tool.

Further, the right side of the tool holder is provided with a back shaft, and the material rod is inserted into the pushing device, the main shaft of the machine tool and the back shaft, and the tool and the movable tool move radially to process the material rod.

Further, the lower part of the back shaft is provided with a receiving box.

Further, the connecting plate is fixed on the tool holder by screws.

The beneficial effects of the utility model are:

The utility model solves the technical defect that the tool holder of the CNC machine tool in the prior art can only be equipped with a fixed number of knives by improving the existing tool holder, flexibly increases the number of knives through the connecting block, and also increases the processing angle , which reduces the difficulty of processing complex parts and improves work efficiency.
