[0018] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0019] The drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0020] See also Figure 1-4 A toothed disc processing tool comprises a positioning plate 1, on which a plurality of positioning holes 5 are provided. The positioning holes 5 are designed according to toothed discs of different sizes. A positioning pin 2 is provided on the positioning plate 1, through which the first toothed disc 3 and the second toothed disc 4 can be positioned respectively.

[0021] The positioning pin 2 and the positioning hole 5 are adapted to each other.

[0022] The positioning pin 2 is a cylindrical structure, and the cross section of the positioning hole 5 is circular.

[0023] The diameter of the positioning pin 2 is consistent with the diameter of the positioning hole 5 .

[0024] The positioning holes 5 are respectively arranged in three areas of the positioning plate 1 , and there are nine positioning holes 5 in each area.
