[0033] The following detailed implementation manners shown are intended as descriptions of various configurations of the subject technology of the present utility model, and are not intended to represent the only configuration in which the subject technology of the present utility model can be practiced. The detailed implementation manners include specific details intended to provide a thorough understanding of the subject technology of the present utility model. However, it will be clear and obvious to those skilled in the art that the subject technology of the present utility model is not limited to the specific details shown herein, and can be practiced without these specific details.

[0034] It can be understood that in this article, relational terms such as "first" and "second" are intended to distinguish one entity or operation from another entity or operation, and are not intended to explicitly or implicitly imply any actual relationship or order between these entities or operations.

[0035] The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0036] Referring to Figures 1 to 6 As shown, a detachable arrow for training includes an arrow body 2 mounted on an arrow shaft 1:

[0037] The arrow shaft 1 is provided with a mounting hole 11, the arrowhead body 2 is provided with a mounting post 21 that cooperates with the mounting hole 11, the mounting post 21 is provided with a positioning ball 22, the side wall of the mounting hole 11 is provided with a positioning groove 12 that cooperates with the positioning ball 22, the mounting post 21 is further provided with an elastic member 23 that pushes the positioning ball 22 into the positioning groove 12, a part of the positioning ball 22 is located in the positioning groove 12, and another part of the positioning ball 22 is located in the mounting post 21;

[0038] The arrowhead body 2 is further provided with a sleeve 24 sleeved outside the arrow shaft 1.

[0039] Generally, during the process of the arrowhead piercing into the target position, the end of the arrow shaft 1 in contact with the arrowhead bears a large force, and this force is the inertial force generated during the flight of the arrow. When the arrowhead and the arrow shaft 1 are connected by threads, on the one hand, it is not easy to assemble the arrowhead and the arrow shaft 1, and on the other hand, during the process of the arrowhead piercing into the target position, the threads bear a large force and are prone to thread damage.

[0040] By using the cooperation of the positioning ball 22 and the positioning groove 12, the end face of the mounting post 21 can directly contact the bottom wall of the mounting hole 11, so that there is a larger contact area between the arrowhead and the arrow shaft 1, and the arrow shaft 1 is not easily damaged during long-term use.

[0041] In addition, since the arrow shaft 1 and the arrowhead generally do not bear radial forces, therefore, using the cooperation of the positioning ball 22 and the positioning groove 12 can meet the assembly requirements of the arrowhead and the arrow shaft 1.

[0042] When installing or removing the arrowhead, only need to pull the arrowhead, the positioning groove 12 applies a force to the positioning ball 22, and overcoming the elastic force of the elastic member 23 can make the positioning ball 22 enter the mounting post 21, so that the positioning ball 22 is disengaged from the positioning groove 12, and the arrowhead can be removed. When installing the arrowhead, insert the arrowhead onto the arrow shaft 1 in the opposite direction, and the positioning ball 22 automatically enters the positioning groove 12 under the action of the elastic member 23, and the operation is very convenient.

[0043] Refer to Figures 1 to 6 As shown, in some embodiments, the mounting post 21 is provided with a mounting groove 25 for mounting the positioning ball 22, the side wall of the mounting groove 25 is provided with a through hole that cooperates with the positioning ball 22, and the diameter of the through hole is smaller than the diameter of the positioning ball 22. The diameter of the through hole being smaller than the diameter of the positioning ball 22 can prevent the positioning ball 22 from falling off the mounting post 21 and improve the stability of the arrowhead.

[0044] In some embodiments, the elastic member 23 is installed in the mounting groove 25.

[0045] The elastic member 23 is an elastic ring. The positioning ball 22 is located between the positioning groove 12 and the elastic member 23. The elastic ring is provided with a notch 231 that facilitates the deformation of the elastic ring.

[0046] The elastic ring may also be provided with a hole body for facilitating the operation of the elastic ring. The hole body cooperates with a circlip pliers to conveniently operate the elastic ring.

[0047] In some embodiments, a positioning plate 26 for positioning the elastic ring is further provided in the mounting groove 25. The positioning plate 26 is fixed to the mounting groove 25 by threads. The mounting groove 25 is provided with internal threads, and the positioning plate 26 is provided with external threads. The positioning plate 26 is further provided with an operation hole for facilitating the rotation of the positioning plate. The cross-sectional shape of the operation hole is polygonal.

[0048] Refer to Figures 1 to 6 As shown, in some embodiments, the positioning plate 26 is completely located in the positioning groove 12. The positioning groove 12 is an annular groove, and a part of all the positioning balls 22 are located in the same positioning groove 12.

[0049] There are at least two positioning balls 22, and at least two positioning balls 22 are evenly arranged along the circumferential direction of the mounting post 21. Four positioning balls 22 may be provided to have a higher connection strength between the arrowhead and the arrow shaft 1.

[0050] In some embodiments, the arrow shaft 1 has an extension portion 13. The extension portion 13 and the arrow shaft 1 are of an integral structure. The diameter of the extension portion 13 is smaller than the diameter of the arrow shaft 1. The outer diameter of the sleeve 24 is equal to the outer diameter of the arrow shaft 1.

[0051] A rubber ring 27 is provided at the end of the sleeve 24. The rubber ring 27 is bonded to the sleeve 24.

[0052] The sleeve 24 and the mounting post 21 are both of an integral structure with the arrowhead body 2.

[0053] By providing the rubber ring 27, damage to the sleeve 24 can be prevented, and the service life of the arrow shaft 1 is extended.

[0054] The above has introduced the technical solutions of the subject matter of the present invention and the corresponding details. It can be understood that the above introduction is only some implementation schemes of the technical solutions of the subject matter of the present invention, and some details may also be omitted during its specific implementation.

[0055] In addition, in some implementation schemes of the above utility model, it is possible to combine multiple implementation schemes. Various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above implementation schemes according to needs during specific implementation to obtain a better application experience.
