[0031] In this embodiment, the dart shaft 2 has a multi-faceted shape throughout, which can achieve the effect of being locked in place and not easy to slip when the dart shaft 2 is twisted; at the same time, the multi-faceted dart shaft 2 is not easily stretched when the dart wing 4 is inserted, compared with the traditional cylindrical dart shaft 2, so that the dart wing 4 is fixed more tightly and not easy to fall off.

[0032] In the above embodiment, preferably, Figure 7 As shown, the polygon is a triangle, a rectangle, a parallelogram, a trapezoid, a regular pentagon or a regular hexagon.

[0033] In this embodiment, the cross-section of the dart shaft 2 is a regular hexagon, that is, the dart shaft 2 has a six-sided shape throughout, so that when the dart shaft 2 is twisted, the six-sided shape can play a role in being locked and not easy to slip; at the same time, compared with the traditional cylindrical dart shaft 2, the six-sided dart shaft 2 is not easily stretched when the dart wing 4 is inserted, so that the dart wing 4 is fixed more tightly and not easy to fall off.

[0034] In the above embodiment, preferably, Figures 3 to 6 As shown, a reinforcing rod 5 is fixed inside the dart shaft 2, and the reinforcing rod 5 is a carbon fiber rod, a copper rod, an iron rod, an aluminum rod or a tungsten steel rod.

[0035] In this embodiment, the dart shaft 2 and the reinforcing rod 5 adopt a design structure combining two materials, that is, a carbon fiber rod is built into the plastic dart shaft 2. The reinforcing rod 5 can further strengthen the strength of the dart shaft 2, making the dart shaft 2 less likely to bend or break, thereby increasing the service life of the dart shaft 2.

[0036] In the above embodiment, preferably, Figure 4 As shown, an annular groove 61 is formed at the end of the reinforcing rod 5 , and a snap ring 62 matching the annular groove 61 is formed in the dart shaft 2 . The snap ring 62 is engaged in the annular groove 61 to fix the reinforcing rod 5 in the dart shaft 2 .

[0037] In this embodiment, the annular groove 61 at the end of the reinforcing rod 5 can ensure the firmness of the connection between the reinforcing rod 5 and the dart shaft 2, thereby making the reinforcing rod 5 and the dart shaft 2 more stable and reliable, thereby ensuring the stability of the dart.

[0038] In some possible embodiments, the dart shaft may be designed as a two-part structure:

[0039] like Figure 5 and Figure 6 As shown, the shaft of the dart shaft 2 includes a front shaft 21 and a rear shaft 22, the dart wings 4 are mounted on the rear shaft 22, and the front shaft 21 is connected to the dart body 1;

[0040] The reinforcing rod 5 passes through the front rod body 21 and can be installed by simply pressing and inserting it.

[0041] The rear section of the shaft is formed into two interchangeable structures:

[0042] One is the rear cross slot can be installed with traditional folding wings: Figures 2 to 8 As shown, the dart shaft 2 is provided with a slot 71 for accommodating the dart wing 4, and the dart wing 4 is formed with a limiting ring surrounded by a limiting slot 72 provided on each wing 41, and a limiting clamping ring 73 is installed on the limiting ring. The shape of the limiting clamping ring 73 is the same as the shape of the cross-section of the shaft, that is, the shape of the limiting clamping ring 73 is a triangle, rectangle, parallelogram, trapezoid, regular pentagon or regular hexagon. When the dart wing 4 is inserted into the slot 71, the limiting clamping spring 73 is sleeved on the dart shaft 2.

[0043] In this embodiment, the limiting spring 73 on the dart wing 4 is used to tighten the dart wing 4 on the dart shaft 2 when the wing 41 is inserted into the dart shaft 2, ensuring that the dart wing 4 is not easily stretched when the dart is in use, thereby making the dart wing 4 more tightly fixed and not easy to fall off.

[0044] Another type is that the rear shaft 22 and the dart wings 4 are formed into an integral structure, such as Figure 1 shown.

[0045] The above two structures can easily realize the interchangeability between the integrated wing and the traditional folding wing. If the rear wing is damaged, it can be replaced separately, saving some material costs.

[0046] In the above embodiment, preferably, Figure 4 、 Figures 9 and 10As shown, the dart shaft 2 also includes a connecting member 23, one side of which is formed with a column 231, the other side of the connecting member 23 is an integrally formed structure with the front section of the shaft and is formed with an identification plate 232, and a receiving cavity 233 is formed on the rear section of the shaft 22, the column 231 is sleeved in the receiving cavity 233, and a plurality of identification teeth 235 are formed on both sides of the identification plate 232.

The rear section of the shaft 22 on the dart wing 4 can be mounted on the main body 231 of the connecting piece 23 through the accommodating cavity 233 by simply pressing, so that the integral wing and the traditional folding wing can be easily interchanged. Part of the dart wing 4 that is damaged can be replaced separately, saving some material costs; the identification teeth 235 are used to identify the length of the dart shaft 2, that is, different numbers of teeth 235 correspond to dart shafts 2 of different lengths, such as 1-6 bars (the number of teeth of the identification teeth 235) represent dart shafts 2 No. 1-6, six lengths.

[0048] In any of the above embodiments, preferably, Figure 9 and Figure 10 As shown, a snap ring 238 is formed on the column 231 along the circumferential direction, and a snap ring groove 239 is formed in the accommodating cavity 233 , and the snap ring 238 is snapped into the snap ring groove 239 .

[0049] In this embodiment, the matching snap ring groove 239 and snap ring 238 are used to axially limit the column 231 and the accommodating cavity 233 to prevent the column 231 from accidentally falling out of the accommodating cavity 233 .

[0050] In the above embodiment, preferably, Figure 9 and Figure 10 As shown, a vertical bar 2310 is formed on the column 231 along the axial direction, a vertical groove 2311 is formed in the accommodating cavity 233 , and the vertical bar 2310 is snapped into the vertical groove 2311 .

[0051] In this embodiment, the matching vertical grooves 2311 and vertical bars 2310 are used to radially limit the column 231 and the accommodating cavity 233 to prevent the column 231 from rotating in the accommodating cavity 233 .
