[0023] like Figure 2 and Figure 4 As shown, the blade slot 11 includes a first positioning surface 111 and a second positioning surface 112, the first positioning surface 111 and the second positioning surface 112 are arranged at 90 degrees, and one end of the blade 3 away from the cutting edge contacts the first positioning surface 111 and the second positioning surface 112 respectively.

[0024] Specifically, the cutter disc 1 is sequentially provided with 8 blade slots 11 along the circumferential direction, and the first positioning surface 111 and the second positioning surface 112 of the blade slot 11 are respectively against one end of the blade 3, and the blade 3 is detachably connected to the second positioning surface 112 of the blade slot 11. The tool handle 2 is provided with 8 positioning blocks 21 along the circumferential direction. First, the cutter disc 1 is connected to the tool handle 2, and the positioning blocks 21 are respectively located at the bottom of the first positioning surface 111 and the second positioning surface 112, and are against the first positioning surface 111 and the second positioning surface 112 to form a positioning cone surface. Then the blade 3 is placed on the positioning cone surface, and then the blade 3 is connected to the second positioning surface 112 by a second bolt.

[0025] First, insert the connecting outer cone 14 of the cutter disc 1 into the inner positioning inner cone hole 24 of the handle 2, rotate the cutter disc 1 so that the connecting outer cone 14 is threadedly fixedly connected with the connecting stud 25 in the handle 2, then pass the pin through the cutter disc 1 and the handle 2 for positioning, and then fix the cutter disc 1 and the handle 2 with the first bolt. The double connection method is used to enhance the connection reliability between the cutter disc 1 and the handle 2.

[0026] In the above structure, by providing a detachable cutter disc 1, a detachable handle 2 and a detachable blade 3, after long-term use, when the cutter disc 1, the handle 2 and the blade 3 are worn, they can be replaced separately, reducing the replacement cost and production cycle, and increasing the service life of the tool. In addition, by providing a blade groove 11 and a positioning block 21, high-precision positioning of the blade 3 is achieved, and the accuracy and efficiency of rapid replacement of the blade 3 are improved.

[0027] like Figure 3 and Figure 4 As shown, in one embodiment, the tool disc 1 of the quick-change high-precision positioning tool is provided with two first positioning pin holes 12 and a plurality of first fixing holes 13, and the tool handle 2 is provided with two second positioning pin holes 22 and a plurality of second fixing holes 23, the first positioning pin hole 12 and the second positioning pin hole 22 are positioned and connected by a pin shaft, and the first fixing hole 13 and the second fixing hole 23 are fixedly connected by a first bolt.
