The three sets of positioning rods 11 are all sleeved with springs 13. The two ends of the springs 13 are respectively connected to the positioning plate 7 and the top block 12. When in use, the connecting rods 11 are connected to the positioning plate 7 and the top block 12. The connecting shaft 2 is clamped on the machine tool chuck, so that the tooling sleeve 1 is fixedly installed on the chuck, and then the tool shaft to be processed is installed in the tooling sleeve 1, so that one end of the tool shaft is against the inner left end of the positioning disk 7. When the tool shaft extends into the positioning disk 7, the tool shaft squeezes the top block 12, so that the top block 12 pushes the positioning rod 11 to slide outward, and the spring 13 is compressed, so that the top block 12 and the outer wall of the tool shaft are kept in close contact, so that the tool shaft can be clamped in the center, and the adjusting screw rod 5 is rotated by the hand wheel 6 to move the adjusting screw rod 5 upward, so that the adjusting screw rod 5 pulls the positioning disk 7 on the guide rod 9 through the transmission strip plate 8. The tool shaft is then clamped in an annular manner by the three groups of clamping studs 3, thereby preventing the tool shaft from being displaced axially during turning and milling, and improving the fixing effect of the tool shaft. This makes it easier to adjust the amount of extension of the tool shaft during machining, thereby preventing the tool shaft from being displaced axially during turning and milling, and improving the fixing effect of the tool shaft.
