For example, the handle portion 212 is a hollow structure, and the feather joint portion 211 is a solid structure filled with foaming material.

[0051] In other embodiments, the feather shaft 210 is a carbon fiber hollow tube with a gradually changing tube diameter from the handle portion 212 to the feather joint portion 211, which gradually changes from thick to thin, so as to match the feather portion 220 to achieve balanced weight distribution and improve flight stability.

[0052] Referring to Figure 10 and Figure 11 The feather joint portion 211 has opposite first and second side surfaces, and the first side surface 211a is inwardly recessed to form one or more first recessed portions 2111 for inserting the feather portion 220. Similarly, the second side surface is inwardly recessed to form one or more second recessed portions for inserting the feather portion 220. The feather portion 220 is inserted into the recessed side surface to achieve fixation of the feather portion 220 on the feather shaft 210. This fixation method has good fixation effect and high overall connection stability, and the flight stability of the artificial feather is maintained.

[0053] In the present embodiment, the first side surface 211a is inwardly recessed to form a continuous first recessed portion 2111, which starts at the junction of the handle portion 212 and the feather joint portion 211 and ends at the extension end of the feather joint portion 211.

[0054] Therefore, the feather part 220 is composed of a first feather part embedded in the first recessed part 2111 and a second feather part embedded in the second recessed part, which can be symmetrical or asymmetrical. The connection stability of such feather part is good, so that the artificial feather is not easy to be damaged and has the resistance to beating.
