Specifically, the aperture with repeated hole 704 meets following formula:

D=xD+yL+zW+C,

Wherein, d indicates the aperture for matching repeated hole 704, and D indicates that the outer diameter of ring body 701, L indicate the axial length of ring body 701, W Indicate the ring width of ring body 701；C indicates constant；X, y, z indicates related coefficient.

In the embodiment, the aperture d with repeated hole 704 meets: d=D+L+W-7.964.

Fig. 6 is the structural schematic diagram of ring body in the utility model embodiment three, and shown in Figure 6, the embodiment is optional In scheme, ring body 701 includes the multiple subrings nested together, whole convenient for increaseing or decreasing ring body 701 by multiple subrings Weight, be convenient for adjustment.

It is illustrated so that the quantity of subring is two as an example in the embodiment, for the ease of distinguishing two subrings, two sons Ring is referred to as: the first subring 709 and the second subring 710, and the interior circular diameter of the first subring 709 is greater than or equal to the second subring 710 outside diameter, such first subring 709 are just nested in the outside of the second subring 710；In use, the second subring 710 is placed on On cutter hub；By symmetrical two in ring body 701 with installation and adjustment in repeated hole 704 between first subring 709 and the second subring 710 Device achieves a fixed connection.It is corresponding with repeated hole 704 since ring body 701 is divided for the first subring 709 and the second subring 710 It is divided into two half bore, a half bore is located in the first subring 709, another half bore is located in the second subring 710.
