After adopting the above scheme, when in use, the regular hexagonal shank 2 is sequentially penetrated through the internal thread knob 8 and the tube body 4 and then embedded in The oilstone cutter head is inserted into the circular groove 31, and the positioning block 22 is inserted into the positioning groove 42 after passing through the through hole 811 for positioning, so as to push the regular hexagonal tool handle 2 to remain stable, and the internal thread knob 8 is tightened on the tube body 4. After tightening the internal thread knob 8, the through hole 811 and the positioning block 22 are in a misaligned state, and the retaining ring 81 is used to limit the positioning block 22, so that the installation of the oilstone cutter head can be completed, and the fixing rod 3 is fixed to the machine tool tool holder through the mounting flange 5 and bolts. The oilstone cutter head body 1 of the utility model is installed in a plug-in manner, and is limited by the internal thread knob 8. It is convenient and stable to install, and is easy to disassemble and replace. The oilstone cutter head body 1 and the regular hexagonal tool handle 2 are detachably installed, which is convenient for replacing a damaged oilstone cutter head body 1 or regular hexagonal tool handle 2 separately, thereby reducing the maintenance cost.

[0035] Optionally, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a regular hexagonal plug block 11 and a locking bolt 7. The regular hexagonal plug block 11 is fixed to the end of the oilstone tool head body 1. The regular hexagonal tool handle 2 has a regular hexagonal slot 21 for the regular hexagonal plug block 11 to be embedded. The locking bolt 7 is installed on the regular hexagonal tool handle 2 by screwing.

[0036] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, an auxiliary stabilizing component 6 is further included, and the auxiliary stabilizing component 6 is arranged in the circular groove 31, and the auxiliary stabilizing component 6 includes: a push block 61, a telescopic spring 63, a flip arm 65 and a flip connecting rod 64, the push block 61 is located in the circular groove 31, and a telescopic rod 62 is fixed between the push block 61 and the inner wall of the circular groove 31, the telescopic spring 63 is sleeved on the telescopic rod 62 and is between the push block 61 and the inner wall of the circular groove 31, a plurality of flip arms 65 are hinged in the circular groove 31 at equal intervals along the circumferential direction, and a stabilizing block 66 is fixed at the free end of the flip arm 65, and the flip connecting rod 64 is fixed to the inner wall of the circular groove 31. 2 has a stable card slot 23 for the stable card block 66 to be embedded in, one end of the flip connecting rod 64 is hinged to the push block 61, and the other end is hinged to the flip arm 65. After adopting the above scheme, after the regular hexagonal tool handle 2 is pushed to be embedded in the circular groove 31, the regular hexagonal tool handle 2 pushes the push block 61 to move, and the push block 61 pushes the telescopic rod 62 and the telescopic spring 63 to contract. At this time, the flip connecting rod 64 flips and moves, and at the same time pulls the flip arm 65 to flip down, so that the stable card block 66 is embedded in the stable card slot 23 to form a snap fit, and the regular hexagonal tool handle 2 is clamped by the stable card block 66, so as to further improve the stability of the oilstone tool head installation.
