[0002] A bow and arrow consists of an arrow head, an arrow shaft, and a tail. The main part of the tail is the fletching. The fletching is glued to the back of the arrow shaft and evenly distributed along the radial direction of the arrow shaft. It plays a role in balancing and maintaining the direction of the arrow during flight. Feathers are generally divided into feathers and plastics. Feathers are made of natural feathers and are very expensive. Feathers are afraid of water and will affect the quality of flight on rainy days or in weather with high humidity.

[0003] Plastic fletching is made of soft and flexible plastic, and it is the choice of most archers. Plastic fletching is cheap, relatively quiet when flying, not afraid of water, and can basically adapt to all kinds of weather.

[0041] The installation cylinder 2 comprises an outer cylinder 21 and an inner cylinder 22 installed in the outer cylinder 21, the outer cylinder 21 is provided with a positioning groove 211 matched with the positioning edge 12, the outer cylinder 21 comprises a mounting end and a connecting end opposite to the mounting end, the positioning groove 211 passes through the mounting end, the inner wall of the outer cylinder 21 is provided with a positioning ring for positioning the connecting ring 11, one end of the connecting ring 11 contacts the positioning ring 212, and the other end of the connecting ring 11 contacts the inner cylinder 22;

[0042] The inner cylinder 22 is fixed to the outer cylinder 21 by threads.

[0043] The vane assembly 1 is made of plastic. The mounting tube 2 can be made of metal material, or the mounting tube 2 can also be made of a material with a strength higher than that of the vane assembly 1.

[0044] The strength of the positioning edge 12 may be higher than the strength of the sheet body 13 , and in particular, the anti-deformation strength of the positioning edge 12 should be set higher than the anti-deformation strength of the sheet body 13 .

[0045] Reference Figures 1 to 6 As shown, in some embodiments, an assembly ring 221 is provided at one end of the inner cylinder 22 away from the connecting ring 11, and the assembly ring 221 is connected to the inner cylinder 22 via a connecting piece 222, and the outer cylinder 21 is provided with an external threaded portion, and the assembly ring 221 is provided with an internal thread that cooperates with the external threaded portion.

[0046] The major diameter of the external threaded portion is smaller than the outer diameter of the outer cylinder 21 , the outer diameter of the assembly ring 221 is equal to the outer diameter of the outer cylinder 21 , and the inner cylinder 22 , the assembly ring 221 , and the connecting piece 222 are an integrated structure.

[0047] The outer diameter of the arrow shaft is usually of a consistent size to give the arrow shaft better stability. Therefore, the outer diameter of the mounting ring 221 is equal to the outer diameter of the outer tube 21, and the outer wall of the outer tube 21 has no protruding parts, so that the arrow shaft has better performance as a whole.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the positioning groove 211 includes a first positioning portion and a second positioning portion whose width is greater than that of the first positioning portion and is communicated with the first positioning portion, the first positioning portion passes through the outer wall of the outer cylinder 21, the second positioning portion passes through the inner wall of the outer cylinder 21, the positioning ridge 12 cooperates with the second positioning portion, and the sheet body 13 protrudes from the outer wall of the outer cylinder 21 through the first positioning portion, and the side of the positioning ridge 12 away from the sheet body 13 is flush with the inner wall of the outer cylinder 21.
