Technical Field

The invention relates to a fishing hook, in particular to an automatic elastic expansion fishing hook.

Background

The ordinary J-shaped fishhook is used for fishing, and an angler mainly observes the 'floating image' of the float to judge whether the angler sucks bait into the mouth or not and then determines whether to lift a rod or not, so that the angler has to pay high attention, the angler is difficult to avoid fatigue for a long time, the leisure and relaxation purpose cannot be achieved, hook leakage and fish escape sometimes occur, and the opportunity of lifting the rod is difficult to grasp for a novice. Various automatic fishing hooks have been invented to solve the problem, among them, CN210143620U describes an automatic expanding fish-running-preventing hook; CN203313922U describes a self-expanding fishhook; the typical case of the crank-shaped self-expanding fishhook described in CN203416732U is, but the disadvantage is that the self-expanding fishhook is heavier than the common J-shaped fishhook for fishing heavy fish because the structure is more complicated than the common J-shaped fishhook, so it is not easy to suck the bait into the mouth, especially the suction force of small fish is small, and it is more difficult to suck into the mouth.

Disclosure of Invention

The invention aims to provide an automatic elastic expansion fishhook which aims at the existing technical situation that bait is easy to be sucked into a fishmouth by fishes.

In order to achieve the purpose, the invention adopts the following technical scheme: the fishhook comprises two hook handles (hereinafter, the two hook handles are expressed by a main hook handle and an auxiliary hook handle) which are connected in a V shape (in a natural expansion state), the joint is a hook head capable of being connected with a fishing line, hook bodies (including the condition that only one hook handle extends to form the hook body) with the same or different sizes and shapes extend from the tail ends of the main hook handle and the auxiliary hook handle respectively to form an automatic elastic expansion fishhook body, and a restraint device for preventing the fishhook from expanding and a release device for triggering the fishhook to expand are arranged on the fishhook body. Because the buoyancy received by the floating body is larger, the total weight of the fishhook in water minus the total buoyancy becomes smaller (even negative and floating), the fishhook is lighter and more flexible in water, and the bait and the hook body are easier to be sucked into the mouth of a fish by the fish.

Further the floating body is arranged on the hook handle.

The floating body is arranged on only one hook handle, the size and the position of the floating body are determined to ensure that the hook head keeps touching the water bottom slightly, and the hook body and the bait are erected or inclined towards the water surface when the hook is in a restraining state (also comprising the step that the hook head keeps erecting or inclined towards the water bottom hook body and the bait by adding a heavy weight when the hook is in a floating state). This condition is more conducive to the fish sucking the bait and the hook body into the mouth.

The floating body is further thickened from the direction from the hook body to the hook head. Therefore, the small fish can be sucked conveniently, the floating body is ensured to have a certain water discharge volume and generate enough buoyancy, and meanwhile, the resistance of the fishhook moving towards the suction direction of the fishmouth is reduced.

The hook head, the hook handle and the hook body are made of metal materials.

The hook head, the hook handle and the hook body are made of plastics or the hook head and the hook handle are made of plastics, and at least one hook body is made of a metal material.

The main hook handle is formed by a flat main hook handle rear section extending from a main hook handle front section and a main hook handle front section tail end lower surface (upper outside paper, lower inside paper and same below paper in a schematic view), the auxiliary hook handle is formed by a flat auxiliary hook handle rear section extending from an auxiliary hook handle front section and an auxiliary hook handle front section tail end upper surface, the main hook handle front section is longer than the auxiliary hook handle front section, the main hook handle rear section and the auxiliary hook handle rear section are partially overlapped in a constraint state, and the overlapped main hook handle rear section upper surface and the auxiliary hook handle rear section lower surface keep a certain distance. The purpose of making the rear section of the hook handle into a flat shape is that the rear sections of the main hook handle and the auxiliary hook handle are slightly deformed in the expansion direction in a constrained state, and when a fish bites the lower surface of the rear section of the main hook handle and the upper surface of the rear section of the auxiliary hook handle, two inner surfaces of the rear sections of the main hook handle and the auxiliary hook handle are easy to close, so that the purpose of triggering and releasing the expansion of the fishhook is achieved (the principle is described later).

The rear section of the flat main hook handle is narrowed from the tail end of the front section of the main hook handle to the main hook body.

The floating body is a hollow floating body formed by a surrounding cavity which is formed by downwards extending the periphery of the lower surface of the rear section of the flat main hook handle and is narrowed from the width to the height from the tail end of the front section of the main hook handle to the hook body of the main hook, and filling a substance with the density less than the water density into the surrounding cavity.

The restraining device is composed of a small section of flat buckling strip which is provided with a restraining hole and extends towards the surface direction of the small section of flat buckling strip which is provided with the restraining hole and protrudes upwards and exceeds the upper surface of the rear section of the auxiliary hook handle (under the restraining state) at the tail end of the front section of the main hook handle, and a corresponding protruding restraining pin arranged on the upper surface of the rear section of the auxiliary hook handle, wherein the restraining pin is buckled by the restraining hole under the restraining state, so that the fishhook is kept in the restraining state.

The release device is the rear section of the main hook handle and the auxiliary hook handle which are mutually overlapped in a restrained state. After the fish sucks the bait and the hook body, the lower surface and the upper surface of the rear sections of the main hook handle and the auxiliary hook handle are occluded to drive the two inner surfaces of the rear sections of the main hook handle and the auxiliary hook handle to be close, so that the constraint pin is separated from the constraint hole, and the two hook handles drive the hook body and the hook tip to expand outwards to support or pierce the fish mouth under the action of the outwards expanding elastic force of the hook head. Because of the supporting force of continuous outward expansion, the mouth of the fish mouth is smaller than the cavity of the fish mouth, and the fish cannot be unhooked. Because the rear sections of the two hook handles are flat, compared with a release device formed by metal wires described in a comparison document, the release device has a large contact surface and small pressure, and a fish can release the expansion of the fishhook by using the same occlusal force more easily. This is another reason why the rear sections of the main and auxiliary structure handles are made into flat strip shapes.

It must be pointed out that the thinner the bending part at the top of the hook head is, the smaller the expansion elastic force is, the smaller the up-and-down sliding friction force generated by the expansion elastic force between the restraint pin and the restraint hole is, the easier the restraint pin is to be separated from the restraint hole, and the easier the fish bites the lower and upper surfaces of the rear sections of the main and auxiliary hook handles to trigger the release of the fishhook to the expansion state. This is possible when the hook body is made of metal, because the hook tip of the metal hook body can be made sharp, easily pierce through fish flesh and fish bone, and can hook fish. However, the hook head, the hook handle and the hook body are made of plastic in the prior art. Since the hook tip on the hook body cannot be made as sharp as a metal hook tip, the fish is not easy to be penetrated and the fish bone is not easy to be penetrated. After the fish sucks the bait and triggers release fishhook, when fishing person pulled the fish tape or the fish moved about and pulled the fish tape, binded the gib head of fish tape and driven two hook handles and move gradually outside the fish mouth, two hook handles expand the contained angle and diminish gradually, outside expansion distance between the main, vice hook body diminishes gradually, and the hook body fails to pierce the flesh of fish in addition, if the pulling force is too big then the fishhook hook body can the roll-off fish mouth by force.

Therefore, the hook head is matched with a connecting ring to solve the problem. The middle part of the top side of the connecting ring is bound with a fishing line, the corresponding flat strip-shaped bottom side is hung with the hook heads, the thickness of the bottom side towards the top side of the connecting ring is smaller than the distance between the inner side surfaces of the front sections of the two hook handles in a constraint state, the width is larger than the distance, in the constraint state, the bottom side is laterally placed between the inner side surfaces of the front sections of the two hook handles, the two sides of the bottom side are blocked by the front ends of the rear sections of the flat auxiliary hook handles extending from the tail ends of the hook heads and the front sections of the auxiliary hook handles, after a fish triggers and releases the fishing hook, a fisher pulls the fishing line or the fish to move to pull the fishing line to enable the middle part of the top side of the connecting ring to move along the direction of pulling force, so as to drive the lateral bottom side to overturn to enable the two sides of the bottom side to be clamped, the larger the outward expansion distance between the main hook body and the auxiliary hook body is, the more the fish mouth cavity can be supported, so that the fish is difficult to escape. The inner side surfaces of the front sections of the two hook handles are also provided with insections for increasing friction.

The invention has the beneficial effects that: because there is the body on the fishhook body, this body enables the fishhook and keeps the gib head in aqueous to touch subaquely, coupler body and bait to erect towards the surface of water or the oblique state of standing, this kind of state more is favorable to the fish to absorb bait and fishhook coupler body to the mouth, simultaneously can automatic trigger release fishhook expansion when the fish interlock main hook handle back end lower surface, vice hook handle back end upper surface and prop up the fishmouth, the difficult unhook of fish, and then improve well fish rate, the person of fishing is relaxed more leisure.
