Description

Technical Field

[0001] This utility model relates to the field of fishing tackle technology, and in particular to a force-relieving square hook for silver carp and bighead carp. Background Technology

[0002] In freshwater fishing, silver carp and bighead carp are highly sought-after by anglers due to their large size, strong fighting ability, and delicious flesh. Targeting their filter-feeding habits, the use of block baits combined with multiple hook rigs has become mainstream. This involves fixing pressed block bait below the line and evenly distributing multiple hooks around it. The bait's atomization creates an attractive zone that draws the fish in. When the fish inhale the atomized particles, they accidentally suck the hooks into their mouths, resulting in a catch. The block hook is the core component of this fishing method.

[0003] Currently, because silver carp and bighead carp are mid-to-upper-level filter feeders with strong impact force, many traditional square hooks for silver carp and bighead carp cannot unload when the fishing rig is subjected to impact force, and the hook is prone to coming off, which will seriously affect the user's fishing experience. To address this issue, we propose a force-relieving square hook for silver carp and bighead carp to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a force-relieving square hook for silver carp and bighead carp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A weight-relieving square hook for silver carp and bighead carp includes a buoyancy plate and a main line. A set of extension rods is fixedly connected to the outer surface of the buoyancy plate. A central tube arm is fixedly connected to the end of each extension rod away from the buoyancy plate. A bearing is fixedly embedded inside the buoyancy plate. A bait cover plate is provided on the outer surface of the buoyancy plate. The outer surface of the bait cover plate is in close contact with the outer surface of the bearing. An anti-tangling post is provided on the outer surface of the buoyancy plate.

[0006] In a further embodiment, the outer surface of the main line is provided with a locking bead, and the outer surface of the main line is provided with a bait pressing plate, which is located between the locking bead and the buoyancy plate.

[0007] In a further embodiment, each of the central tube arms is provided with a first spring inside, and each of the central tube arms has a through hole at the end away from the extension rod.

[0008] In a further embodiment, each of the first springs is fixedly connected to a sub-line hook at the end near the through hole, and each of the central tube arms is provided with a rubber plug at the end away from the through hole.

[0009] In a further embodiment, a screw is fixedly connected to the outer surface of the anti-entanglement post, and the screw has threads on its outer surface.

[0010] In a further embodiment, the anti-tangle post is provided with a second spring inside, the second spring is connected to a middle hook, and the main line is connected to the anti-tangle post through a thread.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device, with its leader hook and middle hook working in conjunction with a first and second spring, effectively buffers and absorbs the immense impact force generated when a silver carp or bighead carp struggles violently after being hooked. This prevents the instantaneous rigid tension from exceeding the hook's strength or the fish's lip tissue's tolerance limit, thus avoiding hook failure. It effectively solves the problem that many traditional square hooks for silver carp and bighead carp, being mid-to-upper-level filter feeders with strong impact forces, cannot unload under impact, easily resulting in hook detachment and severely impacting the user's fishing experience. Furthermore, the device's extension rod radially expands multiple through-tube arms, separating the leader hooks from each other and physically preventing tangling. The independently designed anti-tangling post further separates the middle hook from the leader hook, ensuring that the main line and leader do not interfere with each other under water flow. This effectively solves problems caused by tangled hooks and lines in traditional multi-hook rigs, such as uneven bait atomization, hook tip obstruction, and significantly reduced baiting effectiveness.

[0020] Please see Figure 1-4In this utility model, a weight-relief square hook for silver carp and bighead carp includes a buoyancy plate 1 and a main line 3. A bearing 13 is fixedly embedded inside the buoyancy plate 1, and a bait cover plate 2 is provided on the outer surface of the buoyancy plate 1. The outer surface of the bait cover plate 2 is tightly fitted with the outer surface of the bearing 13. A locking bead 5 is provided on the outer surface of the main line 3, and a bait pressing plate 4 is provided on the outer surface of the main line 3. The bait pressing plate 4 is located between the locking bead 5 and the buoyancy plate 1. The bearing 13 fixedly embedded inside the buoyancy plate 1 will form the core base of the fishing rig and is the main source of buoyancy. The bearing 13 is fixedly embedded inside the buoyancy plate 1 and will provide rotational support for the upper components. At the same time, the outer surface of the bait cover plate 2 is tightly fitted with the outer surface of the bearing 13. The main line 3 will serve as the core line connecting the fishing rig and the fishing rod, running through the entire fishing rig. The locking bead 5 is sleeved on the outer surface of the main line 3 for locking and positioning. The bait pressing plate 4 is located on the main line 3 between the locking bead 5 and the buoyancy plate 1, which can effectively press and fix the square bait.

[0021] A set of extension rods 6 are fixedly connected to the outer surface of the buoyancy plate 1. Each extension rod 6 has a central tube arm 17 fixedly connected to its end away from the buoyancy plate 1. Each central tube arm 17 has a first spring 15 inside and a through hole 16 at its end away from the extension rod 6. A sub-line hook 7 is fixedly connected to the end of each first spring 15 near the through hole 16. A rubber plug 14 is provided at the end of each central tube arm 17 away from the through hole 16. One end of the extension rod 6 is fixedly connected to the outer surface of the buoyancy plate 1, and the other end extends outward to connect to the central tube arm 17. Simultaneously, one end of the central tube arm 17 is connected to the extension rod 6. The device is fixedly connected and has a hollow tubular interior to accommodate the force-relieving mechanism. A first spring 15 is located inside each central tube arm 17 and is the core elastic element for force relief of the sub-line hook 7. A through hole 16 is opened at the end of each central tube arm 17 away from the extension rod 6, allowing the line of the sub-line hook 7 to pass through. The sub-line hook 7 is connected to the central tube arm 17 through the first spring 15, and its hook line passes out through the through hole 16. When under force, it can stretch the spring to relieve force. At the same time, a rubber plug 14 is located at the end of each central tube arm 17 away from the through hole 16 to seal the inside of the tube arm and limit the first spring 15, which can effectively improve the stability of the equipment during use.

[0022] An anti-entanglement post 8 is provided on the outer surface of the buoyancy plate 1. A screw 11 is fixedly connected to the outer surface of the anti-entanglement post 8. A thread 12 is threaded onto the outer surface of the screw 11. A second spring 9 is provided inside the anti-entanglement post 8. A center line hook 10 is fixedly connected to the end of the second spring 9 away from the buoyancy plate 1. The main line 3 passes through the thread 12 and is fixedly connected to the end of the second spring 9 away from the center line hook 10. The anti-entanglement post 8 is located on the outer surface of the buoyancy plate 1 and contains the second spring 9. It is the housing of the central unloading mechanism. The screw 11 is fixedly connected to the anti-entanglement post 8. The outer surface mates with the thread 12, and the thread 12 is threaded onto the outer surface of the screw 11 to fix and seal the anti-tangling post 8. The second spring 9 is located inside the anti-tangling post 8, and its end away from the buoyancy plate 1 is connected to the middle line hook 10. At the same time, the middle line hook 10 is fixedly connected to the end of the second spring 9 away from the buoyancy plate 1, forming a center unloading hook. The main line 3 passes through the thread 12 from top to bottom and is fixedly connected to the end of the second spring 9 inside the anti-tangling post 8 away from the middle line hook 10, which can effectively suspend the entire fishing rig on the main line 3.

[0023] The working principle of this utility model is as follows: When using this device, the main line 3 is first passed through the bait pressing plate 4, the locking bead 5, and the bearing 13 of the buoyancy plate 1 in sequence. The cube bait is placed on the buoyancy plate 1, and the bait pressing plate 4 is pressed down. The locking bead 5 is used to lock the main line 3 to fix the entire bait set. Then, the fishing rig is cast into the target fishing spot. The buoyancy plate 1 provides buoyancy, making the fishing rig float in the water. The silver carp and bighead carp will be attracted by the atomized bait. When sucking the atomized particles, they are likely to suck the surrounding leader hook 7 or middle hook 10 into their mouths. When the fish struggles, it will generate an impact force on the hook. The pulling force will be transmitted to the leader hook 7 or middle hook 10. The first spring 15 connected to the leader hook 7 or the second spring 9 connected to the middle hook 10 will be stretched, which can effectively buffer the fish's instantaneous burst force, prevent the hook from being straightened or the fish's lip from being torn, achieve continuous unloading, and eventually tire the fish and successfully catch it.
