Description

Automatic elastic expansion fishhook

Technical Field

The utility model relates to a fishing hook, in particular to an automatic elastic expansion fishhook.

Background

When the common J-shaped fishhook is used for fishing, a fisher can observe the floating image of the float to judge whether the fish sucks the bait into the mouth or not, and then whether the rod is lifted or not is determined, so that the fisher needs to pay attention to the fishhook, the fishhook is tired for a long time, the purpose of relaxing leisure cannot be achieved, the phenomenon that the fish is leaked and escaped occurs, and a new man is difficult to grasp the opportunity of lifting the rod. Thus, various automatic fishing hooks have been invented to solve the problems, one of which is an automatic expansion fish-running preventing type hook (application number CN 201920665986.2); a self-expanding fish hook (CN 201120149619.0); crank-arm-shaped automatic expansion fishhooks (CN 201320299509.1) and the like are typical cases, and the technical scheme of the automatic elastic expansion fishhooks is similar to that of the automatic elastic expansion fishhooks, and the technical scheme is as follows: the upper ends of the two hook arms are connected by the torsion spring to form a fishhook body, the two hook arms are V-shaped in a natural state, the torsion spring at the joint is a hook head capable of binding a fish line, the hook arms are provided with hook arm expansion constraint release devices, and the lower ends of the two hook arms are respectively provided with a hook body extending towards the expansion direction. It should be noted that the fishmouth cavity of most fish is larger than the fishmouth, and the elastic force generated by the torsion spring of the hook head is smaller (the elastic force is too large and affects the trigger release sensitivity of the expansion of the two hook arms), but the fishmouth cavity can prevent the fish from ejecting the hook body in the barb shape from the fishmouth cavity under the release expansion state of the fishhook; meanwhile, as the fish meat on the inner wall of the fish mouth cavity is thinner, the fish hook body is shallower to penetrate into the fish meat, and the fish mouth cavity bone cannot be penetrated generally, when a rod is lifted or fish flees, the fish hook body is easy to break the fish meat and escape; simultaneously, as the fish mouth opening is smaller than the fish mouth cavity, and the elasticity of the torsion spring is smaller, when the fish wire pulls the hook head, the two hook arms are extruded by the fish mouth opening to be close, so that the two hook bodies are close, the fish meat is penetrated by the hook bodies to become shallower, even the fish meat is withdrawn, and the fish is easier to escape.

Disclosure of Invention

The utility model aims at solving the current state of the prior art, and provides an automatic elastic expansion fishhook which is characterized in that when a fishing rod pulls a fishing line or a fish flees to pull the fishing line, the expansion force of two hook arms is larger, the hook bodies on the two hook arms are forced to support the inner wall of the fishmouth cavity more tightly, and further, the fish flees are prevented from escaping.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the fish mouth cavity inner wall tightening device is characterized in that two hook arms are in a corner shape, the two corner-shaped hook arms are connected back to back at corners through elastic movable devices (such as torsion springs or movable devices and elastic device combinations and the like), the two hook arms become rotating levers which rotate around the elastic rotating devices, one section of the hook arm which is used for tightening a hook body of a fish mouth cavity inner wall is a resistance hook arm by taking the corner as a boundary, the other section of the hook arm is a power hook arm, a hook arm expansion constraint release device is arranged on the resistance hook arm, and small holes (comprising small grooves and the like) for penetrating fish wires are formed at the tail ends of the two power hook arms. The two small holes at the tail ends of the two power hook arms are wound together by the fishing line, the penetrated line head and the fishing line at the penetrating end are loosened (the two power hook arms are not tied up) and knotted (dead knot or slip knot), the fishing line wound through the two small holes is tightened when the fishing line is pulled, the two power hook arms generate mutually-closed rotating moment, and the torque generated by the power hook arms is larger when the fishing line is pulled by more winding turns of the fishing line (in practice, various winding and binding modes exist).

The hook body capable of supporting the inner wall of the fish mouth cavity is at least one hook body extending outwards (in the expanding direction) on the outer side surfaces of the tail sections of the left and right resistance hook arms. The drag hook arm is provided with a hook arm expansion constraint release device, namely a 7-shaped constraint hook is arranged on the inner side of a left (left and right exchangeable) drag hook arm, an L-shaped constraint hook is arranged on the inner side of a corresponding right drag hook arm, vertical sections of the two constraint hooks are constraint blocking blocks, and the smaller the width of the constraint blocking blocks in the vertical direction of a plane formed by the two hook arms in an expansion state is, the higher the triggering release sensitivity is; the two hook arms are adjusted by hands, so that the two constraint hooks can be mutually buckled, namely the two constraint blocking blocks mutually block, the two resistance hook arms can not be expanded, and the fishhook enters a constraint state; in the process of sucking fish and biting bait wrapped on the hook bodies of the two resistance hook arms, the two resistance hook arms can be subjected to component force in the vertical direction of a plane formed by the expansion states of the two hook arms, so that the two resistance hook arms move mutually in the direction to cause the release of the two constraint hooks, namely, the two constraint blocking blocks cannot block each other, under the rebound effect of the elastic moving device, the two hook arms expand outwards to drive the hook bodies to prop up the inner wall of a fish mouth cavity, at the moment, the lifting rod pulls a fish line or the fish flees and pulls the fish line, the fish line windy through the two small holes is tightened, the power hook arms generate larger torque, the outward expansion force of the resistance hook arms is larger, the hook bodies are forced to further prop up the inner wall of the fish mouth cavity, and the fish is not easy to escape. So that the hook body tip can be used for fishing even though the hook body tip is blunt. It is thus also possible to construct all parts of the present automatic elastically expandable fish hook from plastic. Because the density of the plastic is smaller than that of the metal, the fishhook is lighter and more flexible in water, is more beneficial to the fish to suck the bait, and has higher fish rate.

Further, a floating body (an object with smaller density than water or a hollow part of the fishhook body) is arranged on the fishhook body, the volumes of the floating bodies are different, the positions of the floating bodies are different, and the fish hook is different in posture in water, for example, the two resistance hook arms are hollow, so that the top ends of the power hook arms can touch the water bottom lightly under the constraint state, and the two resistance hook arms and the hook body can stand or obliquely stand upwards in water, thereby being more beneficial for a fish to inhale bait.

The beneficial effects of the utility model are that

Compared with the prior art, when the automatic elastic expansion fishhook lifting rod pulls the fish line or the fish flees to pull the fish line, the fishhook can further tighten the inner wall of the fishmouth cavity, the fish is not easy to escape, and the fish rate is higher.

Detailed Description

The constitution of the present utility model is further described in connection with the embodiments of the present utility model, but the scope of protection is not limited thereto.

The embodiment of the utility model is as follows: all parts of the automatic elastic expansion fishhook shown in fig. 1 and 2 are injection molded. The selected plastic has the characteristics of high strength, good toughness, strong elasticity, fatigue resistance and the like. The elastic rotating device (5) connecting the corners of the two corner hook arms is a plastic sheet which can be bent and has elasticity. The outer sides of the tail sections of the two resistance hook arms are provided with inverted tooth-shaped hook bodies (9); the two resistance hook arms are provided with hollow floating bodies (8), and the volume and the position of the hollow floating bodies (8) are adjusted to enable the fishhook to lightly touch the water bottom at the top end of the underwater power hook arm (4), the left resistance hook arm and the right resistance hook arm (under the constraint state), the hook body (9) and the bait wrapped on the hook body (9) to stand or obliquely stand towards the water surface direction, so that the fishhook is convenient for a fish to suck and swallow the bait; the inner side of the bottom end of the right resistance hook arm (6) protrudes downwards to form a small square block which is a left resistance hook arm constraint block (10); the inner side of the bottom end of the left resistance hook arm (7) extends out of the L-shaped restriction hook (11) leftwards; the top ends of the two power hook arms (4) are provided with a fish wire hole (3) for penetrating a fish wire. When in use, the two fishing line holes (3) are wound by the fishing line (1), and the penetrated line head and the penetrating end are used for fishing line knot (2).

There are many other improvements that can be made to the embodiments of the present utility model. If small grooves are formed on the inner sides of the lower sections of the two resistance hook arms (namely, the back of the hook body is opposite to the back of the hook body), baits such as earthworms can be clamped and hung; for another example, the elasticity of the plastic sheet used by the elastic rotating device (5) is insufficient, and a tension spring or an elastic band can be added between the two power hook arms; other improvements are not described in detail herein. The above embodiments are merely two specific implementations of the present utility model and should not be construed as being limited by the description of the embodiments. Since modifications and variations may readily occur to those skilled in the art based upon this disclosure, the utility model is not limited to the exact construction and description, and similarly suitable modifications and equivalents are intended to be included within the scope of the appended claims.
