The honing rod 1 and the tool head 2 are connected and integrally arranged. One end of the honing rod 1 far from the tool head 2 is provided with a screw hole, and the diameter of the honing rod 1 is smaller than that of the tool head 2. The top of the tool head 2 is provided with a first fixing hole 4.

[0023] As Figure 2 shown in the figure, a tool row groove 3 is arranged at one end of the tool head 2 far from the honing rod 1. There is a distance between the tool row groove 3 and the end of the tool head 2 far from the honing rod 1. The tool row groove 3 is located in the lower half of the tool head 2, extends to the side of the tool head 2, and is communicated with the outside of the side of the tool head 2.

[0024] As Figure 3 shown in the figure, a second fixing hole 5 is provided at the bottom of the tool head 2. As Figure 4 shown in the figure, the first fixing hole 4 and the second fixing hole 5 are respectively communicated with the tool row groove 3, and both the first fixing hole 4 and the second fixing hole 5 have four. The four first fixing holes 4 are arranged in a rectangular distribution, and the four second fixing holes 5 are arranged in a rectangular distribution. The distance between two adjacent first fixing holes 4 is different from the distance between two adjacent second fixing holes 5. The distance between two first fixing holes 4 distributed in the direction perpendicular to the axial direction of the tool head 2 is greater than the distance between two second fixing holes 5 distributed in the direction perpendicular to the axial direction of the tool head 2. Limit bolts are respectively arranged in the first fixing hole 4 and the second fixing hole 5. By staggering the limit bolts, the fixing effect of the tool row is better.

[0025] The tool row is arranged in the tool row groove 3. The tool row is installed in the tool row groove 3 by screws, and the tool row is limited and fixed by the limit bolts in the first fixing hole 4 and the second fixing hole 5.
