Technical Field
[0001] This utility model relates to the field of fishhook technology, specifically a spring fishhook. Background Technology
[0002] Fishing is an activity that allows people to get close to nature and cultivate their minds. It is an outdoor sport, and people fish in various fishing areas in daily life. As people's quality of life continues to improve, more and more people are fishing, and the demand for fishing gear is also gradually increasing. The fishhook is the core tool for fishing, and its structure, type, and usage techniques directly determine the catch rate. The function of the fishhook is a systematic system centered around "luring fish to bite the bait - securing the hook - preventing escape," combining structural design, material properties, and scene adaptation.
[0003] Chinese utility model patent CN210610763U discloses an automatic spring fishhook with anti-disengagement feature, comprising a torsion spring body, a first hook body, and a second hook body. The two ends of the torsion spring body are connected to the first and second hook bodies, respectively. Both the first and second hook bodies include a hook arm and a hook tip positioned outwards at the end of the hook arm. A limiting support portion is provided on the first hook body. When the first and second hook bodies are pressed inwards along the direction of the torsion spring body under external force, the second hook body contacts and connects to the first hook body through the limiting support portion. The elastic deformation of the torsion spring body applies elastic force to the first and second hook bodies, placing them in a ready-to-trigger state through the limiting support portion. This utility model features a simple structure, ease of use, and utilizes an integrated torsion spring double-hook structure, resulting in high trigger sensitivity, good anti-disengagement effect, and improved catch rate. It is highly practical and suitable for widespread use.
[0004] However, during use, the bait is still fixed by the first and second hooks, which affects the spread of the bait underwater. At the same time, the bait that the first and second hooks can carry is limited, making it inconvenient to attract a large number of fish and failing to meet the needs of use. Therefore, a spring fishhook is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a spring-loaded fishhook, which has the advantage of high fishing efficiency. It solves the problems that in existing fishhooks, the bait is still fixed by the first and second hook bodies, which affects the diffusion of the bait underwater. At the same time, the first and second hook bodies can only hold a limited amount of bait, making it inconvenient to attract a large number of fish and failing to meet the needs of use.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a spring fishhook, comprising a fishhook main line, wherein the fishhook main line is provided with a spring bearing structure capable of bearing a large amount of fish bait on its exterior;
[0007] The spring-bearing structure includes a first space bead fixedly connected to the outside of the main fishing line, a second space bead fixedly connected to the side of the main fishing line away from the first space bead, and a bearing spring provided between the first space bead and the second space bead.
[0008] Furthermore, the main line of the fishhook passes through the load-bearing spring and is slidably connected to it, and the first and second space beans are of equal shape and size.
[0009] Furthermore, a diversion carrier is fixedly connected to the bottom end of the main fishing line, and a first secondary fishing line and a second secondary fishing line are fixedly connected to the bottom of the diversion carrier respectively.
[0010] Furthermore, the length of the first secondary line is less than the length of the second secondary line, and both the first and second secondary lines have hooks at their bottom ends.
[0011] Furthermore, a fixing ring is fixedly connected to one end of the hook body near the main line of the hook, and both the first and second secondary lines of the hook are fixedly connected to the hook body through the fixing ring.
[0012] Furthermore, the hook body is externally fixedly connected to two barbs, which are respectively located at the top and bottom of the hook body.
[0013] Compared with the prior art, this utility model provides a spring fishhook, which has the following beneficial effects:
[0014] 1. This spring-loaded fishhook, by setting a first space bead and a second space bead, can position the load-bearing spring on the main line of the fishhook, while preventing the load-bearing spring from slipping on the main line. The load-bearing spring makes it easy to fix the bait. When the load-bearing spring enters the water, the bait can quickly spread, which can easily attract surrounding fish. The spread bait can surround the hook body. When the fish sucks the bait, the hook body can easily penetrate the fish's mouth, improving the efficiency of fishing.
[0015] 2. This spring-loaded fishhook, by setting a first hook secondary line and a second hook secondary line, can increase the probability of the hook penetrating the fish's mouth. At the same time, the different heights of the hook can target different types of fish, further increasing the probability of catching them. It solves the problem that the bait in existing fishhooks is still fixed by the first and second hooks, which affects the diffusion of the bait underwater. In addition, the first and second hooks have limited bait capacity, which is not convenient for attracting a large number of fish and cannot meet the needs of use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 In this embodiment, a spring fishhook includes a main line 1. The main line 1 is provided with a spring bearing structure capable of bearing a large amount of bait. The spring bearing structure includes a first space bead 2 fixedly connected to the outside of the main line 1, a second space bead 3 fixedly connected to the side of the main line 1 away from the first space bead 2, and a bearing spring 4 provided between the first space bead 2 and the second space bead 3.
[0021] Specifically, the main line 1 of the fishing hook passes through the bearing spring 4 and is slidably connected to it. The first space bead 2 and the second space bead 3 are of the same shape and size. The bottom end of the main line 1 of the fishing hook is fixedly connected to the diversion carrier 5. The bottom of the diversion carrier 5 is fixedly connected to the first secondary line 6 and the second secondary line 7 of the fishing hook, respectively. The length of the first secondary line 6 is less than the length of the second secondary line 7. The bottom ends of the first secondary line 6 and the second secondary line 7 are both provided with hook bodies 8.
[0022] It should be noted that the bearing spring 4 has a wire diameter of 0.3-0.5mm, a pitch of 2-3mm, and an overall length of 5-8cm. It is made of food-grade stainless steel, which is rust-resistant and elastic. Its spiral structure can form a porous bait storage space, and the amount of bait it can carry at one time is 2-3 times that of traditional fish hooks. The first space bead 2 and the second space bead 3 are made of silicone with a hardness of 60-70 Shore A. They are tightly attached to the main line 1 of the fish hook (diameter 0.2-0.4mm) through radial compression and can withstand a pulling force of 5-8N without slipping. This ensures that the bearing spring 4 is always in the optimal fish-attracting area of 10-15cm above the diversion carrier 5 during casting and playing the fish.
[0023] It should be noted that the diversion carrier 5 is integrally injection molded from ABS engineering plastic. Its bottom has two symmetrical grooves (0.5mm deep) for fixing the connecting ends of the first secondary fishing line 6 and the second secondary fishing line 7, respectively. The first secondary fishing line 6 is 8-10cm long, and the second secondary fishing line 7 is 12-15cm long. Both are made of PE material (0.15-0.2mm diameter, tensile strength 3-5kg) and are fixed to the diversion carrier 5 via heat fusion. The difference in length allows the two hooks 8 to form a 30-45° angle in their natural state, completely preventing tangling.
[0024] Please see Figure 1 and Figure 2 In this embodiment, a fixing ring 9 is fixedly connected to one end of the hook body 8 near the main line 1. The first secondary line 6 and the second secondary line 7 are both fixedly connected to the hook body 8 through the fixing ring 9. Two barbs 10 are fixedly connected to the outside of the hook body 8, and the two barbs 10 are respectively set at the top and bottom of the hook body 8.
[0025] Specifically, the fixing ring 9 is a copper universal swivel, whose inner ring can rotate freely 360°, and whose outer ring is fixed to the hook shank of the hook body 8 by a crimping process, ensuring that the first hook secondary line 6 and the second hook secondary line 7 can rotate in the direction of force when the fish struggles, avoiding the line from twisting and breaking. The hook body 8 is forged from high carbon steel (hardness HRC55-58), with a hook gap width of 5-8mm and a hook tip sharpness of ≤0.01mm, ensuring piercing force.
[0026] It should be noted that the top barb is 1.5mm long and the bottom barb is 2mm long, with rounded ends (0.1mm radius). The advantage of this design is that when the fish sucks the bait from above, the top barb can quickly penetrate the upper lip; when the fish bites from below or the side, the bottom barb can lock the lower lip. This improves the stability of the hooking by 60% compared to traditional single-barb hooks, and the rounded ends reduce tearing of the fish's lips, making it easier to release the fish.
[0027] The working principle of the above embodiments is as follows:
[0028] The bait is filled into the spiral gap of the support spring 4, using the elastic tension of the spring to hold the bait ball in place. After the fishing rig is cast into the target waters, the support spring 4 sinks with the main line to the preset water layer. Under the action of the water flow, the bait slowly atomizes from the spring's openings, forming a columnar atomization zone centered on the spring. After being attracted by the atomized bait, the fish swallows the hook 8 hidden in the bait during the feeding process. If the fish pecks from above, the barb at the top of the hook 8 pierces the upper lip; when sucking from below or the side, the barb at the bottom locks the lower lip. The double barbs work together to ensure a firm hooking.
[0029] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
