[0053] In this embodiment, the pin device 2 includes a pin 29, which is used to match the positioning hole 101 of the rear spoke 100, the diamond pin device 3 includes a diamond pin 30, which is used to match the positioning hole 2 102 of the rear spoke 100, and the anti-misalignment pin 2 19 is used to match the positioning hole 3 103 of the rear spoke 100.

[0054] Specifically, the supporting structures of the column pin device 2 and the diamond pin device 3 are the same, and the supporting structure includes a fixed seat 25 and an L-shaped adjustment reference block 26 and a pin seat 28 installed on the fixed seat 25. The L-shaped adjustment reference block 26 is arranged on the outer side of the pin seat 28. Adjustment pads are provided between the two side edges of the L-shaped adjustment reference block 26 and the pin seat 28. The adjustment pads are installed on the L-shaped adjustment reference block 26 by screws. By increasing or decreasing the number of adjustment pads, the positions of the pin seat 28, the column pin 29 and the diamond pin 30 can be adjusted to ensure that the column pin 29 can be normally inserted into the positioning hole 101 of the rear spoke 100, and the diamond pin 30 can be normally inserted into the positioning hole 2 102, thereby reducing the difficulty of clamping and ensuring the positioning effect.

[0055] There are multiple evenly arranged support plates 4 and clamping devices 11 along the circumference of the clamping mechanism. The position and number of support plates 4 correspond to the position and number of clamping devices 11 to ensure the support and clamping effect of the rear spoke 100.

By increasing or decreasing the number of adjustment pads, the positions of the pin seat 2 40 and the pin 2 41 can be adjusted to ensure that the pin 2 41 can be smoothly inserted into the positioning hole 4 301 of the front spoke 300, thereby reducing the difficulty of positioning and improving the convenience of use.

[0058] The diamond pin device 2 14 includes a pin seat 3 49 and a diamond pin 2 50 mounted on the pin seat 3 49. An L-shaped adjustment reference block 1 26 is mounted on the outer side of the pin seat 3 49. The diamond pin 2 50 is used to match the positioning hole 5 302 of the front spoke 300.

By increasing or decreasing the number of gaskets 36, the position of the support plate 2 37 can be adjusted to ensure the supporting effect of the spiral blade 400. The support plate 2 37 is provided with a positioning surface 37.1, and the positioning surface 37.1 is used to support the spiral blade 400.
