[0024] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The four sides of the positioning block 7 are provided with the same number and specifications of limit cylinders 8, adjustment grooves 9, limit grooves 10, limit columns 11, limit rods 12 and inner rubber pads 13 structures.

Due to the elasticity of the material of the inner rubber pad 13 itself, the limit column 11 is tightened. The inner wall of the sprocket is prevented from being scratched by the hard structure. When the outside is fixed, the limit column 11 can be tightened by four The telescopic column 16 drives the outer rubber pad 17 to press against the outer side of the sprocket. Both fixing methods use uniform force to fix the sprocket in the operating processing center, which is adapted to the operating characteristics of different processing links of the sprocket, avoiding frequent replacement of the positioning mechanism during the processing process, affecting production efficiency.
