[0034] In the embodiment, each feather branch 221 has two opposite side surfaces, and the branchlets 222 are respectively planted on the two opposite side surfaces; in other embodiments, the branchlets 222 can be all planted on the same side surface; it can be adaptively adjusted according to the actual process needs; but it should be noted that, relatively speaking, the setting mode of the branchlets 222 on each feather branch 221 contained in each feather portion 220 is preferably uniform, for example, in a badminton, the branchlets 222 on each feather branch 221 are all set on both sides, or all set on one side, but the mixed mode is not excluded; in a preferred embodiment, the branchlets 222 on each feather branch 221 are all set on both sides, with reference to Figure 3The thin branch 222 on the opposite side is a comb structure, and the toothed part of the comb structure is embedded into the gap of the opposite toothed structure, so as to avoid the airflow from flowing between the gaps of the feather branch 221, and to improve the overall aerodynamic performance of the feather part 220 during flight. In the embodiment, the thin branch 222 is a filament, and the material of the filament is selected from any one or combination of at least two of polyamide fiber, polyolefin fiber, acrylic fiber, and polyester fiber. The cross section of the filament can be circular, rectangular, square, polygonal, etc. Preferably, the cross section of the filament is circular, and the cross section diameter of the filament is 0.03-0.5 mm, for example, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5 mm, etc., but not limited to the listed values, and other unlisted values within the range are also applicable. Notably, the cross-sectional area of the filament is preferably smaller than that of the wire of the feather branch 221. For example, the cross section of the filament is circular, and the cross section diameter of the filament is 0.03-0.3 mm, more preferably 0.03-0.2 mm. In a preferred embodiment, the cross section of the thin branch 222 gradually decreases along the extension direction thereof. For example, the thin branch 222 is a conical structure, including a second root connected to the feather branch 221, and the thin branch 222 of the conical structure gradually thins from the second root to the tip. More preferably, the thin branch 222 is a flat structure, and the cross section gradually decreases along the extension direction thereof, so as to reduce the wind resistance on the side surface. For example, the flat structure can be elliptical, etc. In particular, the flat structure can have a thickness gradually decreasing from the middle to both sides, or gradually decreasing away from the feather shaft 210, so as to further reduce the wind resistance and improve the flight effect.

[0035] In some preferred embodiments, the two ends of the thin branch 222 are fixed on the adjacent two feather branches 221, so as to make the overall feather part 220 more integrated, and to balance the flexibility and stability.

[0036] Please refer to Figure 4 and Figure 5 It is shown that the feather shaft 210 has a feather joint 211 and a handle 212 connected to the feather joint 211.

[0037] The upper surface 210a of the feather shaft 210 includes at least one step surface not in the same plane, and the horizontal height of the upper surface 212a of the handle 212 is higher than that of the upper surface 211c of the feather joint 211. The lower surface 212b of the handle 212 and the lower surface 211d of the feather joint 211 are flush, or can not be flush, i.e., a step surface is provided on the lower surface of the feather shaft 210.

[0038] In a preferred embodiment, the quill 210 is a carbon fiber hollow tube, which gradually decreases in diameter from the handle portion 212 to the vane portion 211.

It is worth noting that the quill 210 can be partially filled with a foaming material, for example, the handle portion 212 is a hollow structure, and the vane portion 211 is a solid structure filled with a foaming material.

[0039] Reference Figure 6 In a preferred embodiment, the difference in horizontal height between the upper surface 212a of the handle portion 212 and the upper surface 211c of the vane portion 211 is h, and 0.02mm≤h≤0.5mm. Specifically, h can be 0.02, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5mm, etc., but is not limited to the listed values. Other values not listed in this range are also applicable.

[0040] In some embodiments, the difference in horizontal height between the upper surface 212a of the handle portion 212 and the upper surface 211c of the vane portion 211 is h, and 0.02mm≤h<0.2mm. In this case, the step surface is shallow, which is used for bonding and fixing a plurality of vane branches 221, facilitating the fixing and bonding operation and improving the stability of the vane portion.

[0041] It is worth noting that the vane portion 220 is bonded to the quill 210 using an adhesive, which is preferably applied to the upper surface of the vane portion 211, and then the vane branches 221 are adhered to the upper surface of the vane portion 211, thereby improving the stability of the vane portion 220. Based on this, when the difference in horizontal height h≥0.2mm, the stability of the vane branches 221 adhered to the upper surface of the vane portion 211 is better, and the vane branches 221 are less likely to break.

[0042] In a more preferred embodiment, the difference in horizontal height between the upper surface 212a of the handle portion 212 and the upper surface 211c of the vane portion 211 is h, and 0.2mm≤h≤0.5mm. Preferably, please refer to Figures 7-8As shown, the feather branch 221 is provided with a fixing sheet 30 on one side of the feather joint 211, so that the feather branch 221 is clamped between the fixing sheet 30 and the feather joint 211, thereby increasing the stability of the feather branch 221; preferably, the fixing sheet 30 can be a carbon sheet, a fiber, or a plastic, or a composite material formed by the above, which has a relatively light weight; preferably, the thickness of the fixing sheet is 0.05-0.5mm, for example, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5mm, etc., but not limited to the listed values, and other values in the range are also applicable; more preferably, the thickness of the fixing sheet 30 is 0.05-0.3mm; the fixing sheet 30 is arranged to improve the flatness of the side surface, thereby reducing the wind resistance and improving the stability of the shuttlecock flight; in a preferred embodiment, the cross section of the fixing sheet 30 gradually decreases along the extension direction thereof; for example, the fixing sheet 30 can also be a flat structure with a cross section gradually decreasing along the extension direction thereof, thereby reducing the wind resistance.

[0043] In another embodiment, referring to Figures 9-10 As shown, the fixing sheet 30 can be a one-piece structure or a split structure, for example, a left-right structure, which includes symmetrically arranged left and right fixing sheets, and the feather branch is clamped between the left fixing sheet and the feather joint, and / or the right fixing sheet and the feather joint. For example, the left and right fixing sheets are respectively fixed on the left and right feather branches 221 by gluing or other fixing methods, so that the feather branches 221 are clamped between the fixing sheet 30 and the feather joint 211, thereby further reducing the weight of the artificial feather 20 and ensuring the stability of the overall structure. The feather branch can be fixed on one side by the fixing sheet and on the other side by other methods, such as gluing or inserting.

[0044] Preferably, the horizontal height difference between the upper surface of the handle 212 and the upper surface of the feather branch 221 is h1, and the horizontal height difference between the lower surface of the feather branch 221 and the lower surface of the feather joint 211 is h2, h2>h1>0, so that the force is balanced during flight after weight distribution in the feather joint, thereby improving the flight characteristics.

[0045] Referring to Figure 11 As shown, the embodiment provides an artificial shuttlecock, which includes a ball head 10 and a plurality of artificial feathers 20 connected to the ball head 10. Due to the improvement of the artificial feather 20, the overall performance of the artificial shuttlecock is improved.
