Description

Technical Field

[0001] This utility model relates to the field of slingshot fishing equipment technology, specifically to a slingshot release device that works in conjunction with a slingshot and a fish dart. Background Technology

[0002] Slingshot fishing equipment generally includes a slingshot, a fishing reel, and a harpoon. The harpoon consists of a head, a shaft, and a tail, which are connected by a threaded connection to form a harpoon. The diameter of the harpoon tail is larger than that of the harpoon shaft, making it easy to hold the tail between the thumb and forefinger and use the slingshot to launch the harpoon. The harpoon tail is connected to the fishing line in the fishing reel. After the harpoon hits a fish, the fishing reel can be turned to reel in the line and pull the fish back.

[0003] In actual use, you pinch the end of the harpoon with your fingers, pull back the slingshot, and release the end to launch the harpoon. However, pinching the harpoon with your fingers can cause the following problems.

[0004] Slingshots use various types of rubber bands. To shoot the harpoon farther, a thicker rubber band is needed. However, a thicker rubber band requires greater tension. Under high tension, squeezing the harpoon with your fingers can cause finger abrasions. Furthermore, under high tension, if the fingers do not have enough grip, the harpoon may detach and cause other accidental injuries. Therefore, to shoot the harpoon farther without harming the fingers, a release device is needed to clamp and hold the harpoon, replacing the hand grip. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pulley-type fish dart release device that uses the lever principle to clamp the fish dart through upper and lower pulleys, and can clamp all conventional dart tails, so as to solve the above-mentioned problem.

[0006] This utility model is achieved through the following technical solution: including a main body, a lever structure, a pulley clamping structure, and a pulley.

[0007] To address the aforementioned technical problems, this utility model provides a slingshot fish launcher with a fish dart pulley release mechanism, comprising a launcher body, a releaser handle at the rear of the launcher body, and a mounting part for attaching the dart tail at the front of the launcher body. The mounting part is equipped with a pulley clamping structure, which is located at the front end of the body and the front end of a lever structure above the body. Pullers are provided at the front end of the pulley clamping structure and the front end of the lever structure above the body. The launcher body also has three-hole side plates located on the left and right sides of the front of the launcher body. A lever structure is also located above the front of the launcher body.

[0008] As a preferred technical solution, the pulley clamping structure is provided with two pulleys, which are respectively installed at the middle of the front part of the main body of the dispenser and at the middle of the front part of the lever structure above the main body.

[0009] As a preferred technical solution, the three-hole side plate is used to connect and fix the main body of the dispenser and the lever structure above the main body of the dispenser.

[0010] As a preferred technical solution, the three-hole side plate, the dispenser body, and the lever structure above the dispenser body are provided with corresponding holes for connecting and fixing the dispenser body and the lever structure with screws.

[0011] As a preferred technical solution, the lever structure is provided with two cantilever arms, a pulley mounting part is provided in front of the middle of the two cantilever arms, and a lever is provided in the rear of the middle of the two cantilever arms.

[0012] As a preferred technical solution, the lever is installed at the middle of the rear part of the two cantilever arms on both sides of the lever structure, and through the movement of the lever, it plays a clamping role.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model can clamp the tail of all conventional fishing darts.

[0015] 2. This utility model uses a pulley clamping structure to clamp the tail of the harpoon with two pulleys. When the harpoon is released, the pulleys will rotate with the force released by the harpoon and there is no friction with the tail of the harpoon, thus ensuring the stability of the harpoon launch.

[0016] 3. This utility model uses the thumb to press the lever above and press forward to hold the harpoon, just like squeezing the harpoon with your hand. In this way, the thumb only needs a small force to hold the harpoon tightly, eliminating the possibility of the release device suddenly going off and the harpoon flying out, thus avoiding accidental injury.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation

[0024] In this embodiment, as shown in Figures 1-5, a pulley harpoon launcher of the present invention includes a main body 1, a lever structure, a pulley clamping structure, a pulley, and a handle; the lever structure is located above the front end of the main body 1, and lever 2 is located on the lever structure 3, 4, and behind it; the rear half of the main body 1 is the handle; the pulley clamping structure is divided into an upper pulley 5 and a lower pulley 6.

[0025] In this embodiment, the lever structure includes a left cantilever 3 and a right cantilever 4. An upper pulley 5 is located in the middle front position of the lever structures 3 and 4, and a lower pulley 6 is located in the middle front position of the main body 1.

[0026] Among them, lever structure 3, 4, and lever 2 are set in the middle position at the rear.

[0027] The lever structure and the main body are connected together through corresponding holes on the left three-hole side plate 8 and the right three-hole side plate 7.

[0028] In addition, in this embodiment, the connection method is to use female and male screws to connect and fix the corresponding holes.

[0029] The working principle is as follows;

[0030] When the user pulls the lever backward, the pulley clamping structure opens, allowing the harpoon to be placed into the clamping channel. Then, pressing the lever forward closes the clamping channel, holding the harpoon in place. Releasing the finger releases the harpoon, which is then launched. If the user does not release the finger while pressing the lever forward, the harpoon will not be launched, preventing accidental firing.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
