AI Technical Summary
The harpoon of existing fishing spears is prone to loosening, which causes the angle of the traction ring to change, affecting the stability and accuracy of entry into the water, and may even injure the user.
A structure including a harpoon shaft, a scratch-resistant ring, a harpoon tail, a tail cap, and a positioning pin is designed. By rotating the tail cap and adjusting the angles of the traction ring, the harpoon string, and the barb, the accuracy of the harpoon entering the water is ensured, and the barb is prevented from scratching the harpoon when not in use.
This achieves stability and accuracy when the harpoon is shot into the water, avoiding angle changes and potential injuries caused by a loose harpoon tail, thus improving safety during use.

Abstract
Description
Technical Field
[0001] This utility model relates to fish darts, and more particularly to a special dart for a 360-degree rotating release device. Background Technology
[0002] A fish spear is a tool specifically designed for shooting fish, usually used in conjunction with a slingshot or fish shooter. It is typically made of metal and has a sharp point that can penetrate fish in the water.
[0003] However, current fishing harpoons have some shortcomings. The harpoon has a harpoon tail with a traction ring attached to it. The harpoon tail is fixed with glue to fix the swing angle. After long-term use, the harpoon tail is prone to loosening. When the harpoon tail loosens, the angle of the traction ring on the harpoon tail will change. This means that when the release device clamps the traction ring, the angle cannot be aligned with the harpoon string and barb. This will affect the stability and accuracy of the harpoon when it enters the water, and may even cause injury to the user's forearm. Utility Model Content
[0004] The main objective of this invention is to provide a dart-specific dispenser that can rotate 360 degrees, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A 360-degree rotating dart for use with a dart includes a dart shaft, a dart tail, and a tail cap. The upper surface of the dart shaft, near the front end, has a dart string opening. A barb limiting groove is formed on the surface of the dart shaft near the front end, with a barb movably installed inside the groove. An anti-scratch ring is fitted onto the surface of the dart shaft at the position of the barb limiting groove. The dart tail is fixedly installed at the rear end of the dart shaft, and a tail cap is movably embedded at the rear end of the dart tail. Positioning pins are embedded inside the dart tail near both sides. A traction ring is fitted onto the rear end of the tail cap. The front end of the dart shaft has a dart tip.
[0007] More preferably, the upper surface of the dart tail and the two sides near the front end are provided with pin holes, and the front surface of the dart tail is provided with a mounting groove, and the pin holes are connected to the mounting groove.
[0008] More preferably, the front end of the tail cap has an annular hole, and the surface of the tail cap near the rear end has an annular groove.
[0009] In a further preferred embodiment, the tail cap is movably embedded in the mounting groove, and the positioning pin passes through the pin hole and the annular groove.
[0010] More preferably, the traction ring is fitted into the ring hole.
[0011] Compared with the prior art, this utility model proposes a dart specifically for a 360-degree rotating dispenser, which has the following beneficial effects:
[0012] In this invention, by setting up a harpoon shaft, anti-scratch ring, harpoon tail, tail cap, and positioning pin in a coordinated manner, when the release device clamps and pulls the traction ring, the tail cap can be rotated before it is pulled to pre-align and adjust the angles of the traction ring, harpoon string, and barb as needed. This facilitates better harpoon entry into the water. When the harpoon is not in use, moving the anti-scratch ring allows the barb to be confined in the barb limiting groove, thus preventing scratches from the sharp part of the harpoon barb. At the same time, when used in heavily weedy areas, moving the anti-scratch ring confins the barb in the barb limiting groove, preventing weeds from snagging the barb and causing the harpoon to be lost.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0017] like Figure 1-2As shown, a 360-degree rotatable dart for a caster includes a dart shaft 1, a dart tail 4, and a tail cap 10. The upper surface of the dart shaft 1, near the front end, has a dart string opening 2. A barb limiting groove 9 is formed on the surface of the dart shaft 1, near the front end. A barb 3 is movably installed inside the barb limiting groove 9. A scratch-resistant ring 5 is fitted onto the surface of the dart shaft 1, located at the position of the barb limiting groove 9. The dart tail 4 is fixedly installed at the rear end of the dart shaft 1. The tail cap 10 is movably embedded at the rear end of the dart tail 4. Positioning pins 6 are embedded inside the dart tail 4, near both sides. A traction ring 7 is fitted onto the rear end of the tail cap 10. The front end of the dart shaft 1 has a dart tip 8. The tail cap 10 can rotate, allowing the angle at which the caster clamps and pulls the traction ring 7 to align with the dart string opening 2 and the barb 3, thus ensuring the accuracy of the dart's entry into the water.
[0018] Furthermore, pin holes 401 are provided on the upper surface of the dart tail 4 and near the front end on both sides, and mounting grooves 402 are provided on the front surface of the dart tail 4. The pin holes 401 are connected to the mounting grooves 402. There is a certain friction between the pin holes 401 and the positioning pins 6, so as to prevent the tail caps 5 from falling out of the mounting grooves 402.
[0019] Furthermore, the front end of the tail cap 10 is provided with an annular hole 1001, and the surface of the tail cap 10 and near the rear end are provided with an annular groove 1002.
[0020] Furthermore, the tail cap 10 is movably embedded in the mounting groove 402, and the positioning pin 6 passes through the pin hole 401 and the annular groove 1002; the cooperation between the positioning pin 6 and the annular groove 1002 can satisfy the requirement of limiting the tail cap 10 while allowing it to rotate in the mounting groove 402.
[0021] Furthermore, the traction ring 7 is fitted into the ring hole 1001.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
