[0034] The lower end of the connecting column 1 is threadedly sleeved on the middle position of the upper end of the rotating disk 2, a circular groove 7 is provided at the outer periphery of the lower end of the rotating disk 2, the outer shell 4 is threadedly sleeved in the circular groove 7, and a plurality of square holes 3 are provided at the outer periphery of the outer shell 4. The outer shell 4 is threadedly sleeved in the circular groove 7, the lower end of the connecting column 1 is threadedly sleeved on the middle position of the upper end of the rotating disk 2, and after the plurality of tool heads 5 are respectively exposed from the plurality of square holes 3, the connecting column 1 can be connected and installed with the driving shaft of the driving mechanism on the machine tool;

[0035] According to the plurality of arc grooves 6, both inner walls of both sides are provided with long grooves 12, and both ends of one of the two long grooves 12 are provided with short grooves 11, and two sliders 903 are respectively slidably arranged in the two long grooves 12, and the third spring 905 is fixedly arranged at one end of one of the two sliders 903, and the support column 904 is fixedly arranged at one end of the third spring 905; one end of one of the two sliders 903 is fixedly arranged at one end of the support column 904, and the second spring 902 is fixedly arranged at the upper end of the support column 904, The clamping block 901 is fixedly arranged at the upper end of the second spring 902, and a clamping slot 10 is provided at one end of each of the plurality of cutter heads 5. The upper end of the clamping block 901 is movably clamped in the clamping slot 10. Two long holes 802 are respectively provided at the upper end of the rotating disk 2 near the two sides of the arc slot 6. The first spring 801 is fixedly arranged on the inner wall of one side of the long hole 802 near the lower end.

At the same time, due to the rotation of the rotating disk 2, the multiple moving devices 9 respectively drive the multiple cutter heads 5 to move inward until the multiple moving devices 9 are inserted into the other short groove 11 of the two short grooves 11. When multiple cutter heads 5 are damaged, the rotating shell 4 is removed to remove them, and the block 901 is pressed downward to drive the second spring 902 to squeeze downward. At this time, the damaged cutter head 5 is taken out, and then the block 901 is embedded in the slot 10 of the new cutter head 5. The block 901 can be released to complete the replacement.
