Description

Technical Field

[0001] The invention relates to a fishhook, in particular to an escape-proof retractable fishhook, belonging to the technical field of fishhook. Background Art

[0002] Fish hooks are tools used to hang baits to attract fish to bite the hooks when fishing. Most of the existing fish hooks are single hook type. Although the fish is hooked during fishing, the fish will spit out the hook violently, or struggle desperately to get off the hook. The hooked fish is easy to slip off the hook. It often happens that the fish is out of the water and then gets off the hook again and falls into the water and escapes. Only people with high fishing skills can get rich catches. In fact, when fishing, the frequency of fish biting the hook is relatively high, but the probability of successfully catching the fish is low. Even if the fish is hooked, it may not be able to come ashore with the hook. Summary of the invention

[0003] In order to solve the problem that fish become unhooked and fall into the water and escape after being hooked, and to improve the catch rate after fish are hooked, the present invention provides an anti-escape retractable fish hook.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] An anti-escape retractable fish hook, characterized in that it comprises a main hook, an auxiliary hook, a hook deployment member and a hook combining member, the auxiliary hook and the main hook are automatically rotated and deployed through the hook deployment member, the main hook and the auxiliary hook are locked by the hook combining member, the hook line comprises a hook deployment section, a hook tying section and a line pulling section, the upper end of the line pulling section is fixedly connected to the fishing rod, the lower end of the line pulling section is fixedly connected with the hook deployment section and the hook tying section, the hook tying section is fixedly connected to the main hook or the auxiliary hook or the hook deployment member, the hook deployment section is fixedly connected to the hook combining member, and the length of the hook tying section is greater than the length of the hook deployment section.

[0006] Further, the display hook is a fixed seat structure, which includes a bottom plate and a toggle torsion spring, and an upper folding edge, a middle folding edge, a lower folding edge, a torsion spring neck, a toggle pin hole and an auxiliary hook hole are provided on the bottom plate, the upper folding edge, the middle folding edge and the lower folding edge are located on the same side of the bottom plate, the torsion spring neck is arranged in the middle position of the bottom plate, and below the middle folding edge, the upper folding edge and the middle folding edge are respectively provided with toggle pin holes distributed in a collinear manner, and the upper folding edge and the lower folding edge are respectively provided with auxiliary hook holes distributed in a collinear manner, and the The auxiliary hook includes an auxiliary hook handle, a limiting member and an upper limiting cap. The auxiliary hook handle of the auxiliary hook can be rotatably mounted in the auxiliary hook holes on the upper folding edge and the lower folding edge. The limiting member is fixed on the auxiliary hook handle, and the upper side of the limiting member is located at the position of the lower end surface of the middle folding edge. The upper limiting cap is fixed on the top of the auxiliary hook handle. The main hook handle of the main hook is fixed on the fixed seat, and the main hook handle is parallel to the auxiliary hook handle. The toggle torsion spring is installed on the torsion spring neck, and the upper and lower legs of the toggle torsion spring are arranged between the bottom plate and the limiting member of the auxiliary hook.

[0007] Furthermore, the hook-combining member is a toggle needle, including a needle bar, an upper limit and a lower limit. The needle bar is sleeved in the toggle needle holes on the upper folding edge and the middle folding edge. The upper limit is fixed at the top of the needle bar to limit the needle bar from falling, and the lower limit fixes the middle position of the needle bar to limit the upward movement of the needle bar. When the main hook and the auxiliary hook are combined, the limit member on the auxiliary hook compresses the upper and lower legs of the toggle torsion spring to combine. At this time, the lower section of the needle bar realizes circumferential limitation on the limit member of the auxiliary hook.

[0008] Furthermore, the hook-combining member is a toggle fork, comprising a needle bar, an upper limit, a lower limit and an engagement fork, the needle bar is sleeved in the toggle needle hole on the upper folding edge and the middle folding edge, the upper limit is fixed at the top of the needle bar, the lower limit fixes the middle position of the needle bar, the engagement fork is fixed at the lower end of the needle bar, and an engagement groove is provided on the engagement fork. When the main hook and the auxiliary hook are combined, the limit piece on the auxiliary hook presses the upper and lower legs of the toggle torsion spring to combine. At this time, the engagement fork at the lower end of the lower needle bar realizes circumferential limitation of the limit piece of the auxiliary hook.

[0009] Furthermore, the limiting member is in the shape of a plate.

[0010] Furthermore, the limiting member is rod-shaped.

[0011] Furthermore, the unfolding hook member is a self-expanding hinge, the main hook handle of the main hook and the auxiliary hook handle of the auxiliary hook are respectively fixed on the left and right hinges of the self-expanding hinge, and when the left and right hinges are in a combined state, the main hook overlaps the auxiliary hook.

[0012] Furthermore, the hooking member is a locking block, and a baffle notch is provided on the locking fork.

[0013] Furthermore, the left-turning leaf and the right-turning leaf are locked by the baffle notch of the locking fork.

[0014] Furthermore, when the main hook and the auxiliary hook are combined, the limiting piece on the auxiliary hook compresses the upper leg and the lower leg of the torsion spring to combine. At this time, the limiting piece of the auxiliary hook and the bottom plate are circumferentially locked by the baffle notch provided on the locking block.

[0015] The beneficial effects of the present invention are:

[0016] Since the fish hook includes a main hook, an auxiliary hook, a hook deployment member and a hook combining member, the auxiliary hook and the main hook are hingedly connected and can be automatically rotated and deployed, the main hook and the auxiliary hook are driven to deploy by the hook deployment member, and the main hook and the auxiliary hook are locked by the hook combining member, the hook line includes a hook deployment section, a hook tying section and a line pulling section, the upper end of the line pulling section is fixedly connected to the fishing rod, the lower end of the line pulling section is fixed with a hook tying section and a hook deployment section, the hook tying section is fixedly connected to the main hook or the auxiliary hook or the hook deployment member, the hook deployment section is fixedly connected to the hook combining member, and the length of the hook tying section is greater than the length of the hook deployment section.

[0017] When hooking a fish, the hook tips of the main hook and the auxiliary hook are wrapped with fish ear material. When the fish bites the hook, it will directly swallow the fish ear material and quickly swim away, and the hook line will be pulled at this time. Since the hook spreading piece is fastened by the hook spreading section, and the length of the hook spreading section is shorter than the length of the hook tying section, the hook spreading section is stressed earlier than the hook tying section, and the hook spreading section will pull the hook piece apart. The main hook and the auxiliary hook will automatically rotate in the mouth of the fish under the drive of the hook spreading piece, so that the main hook and the auxiliary hook are hooked in the mouth of the fish at the same time. No matter how fiercely the fish spits out the hook or struggles to get off the hook, the rapid rotation between the main hook and the auxiliary hook increases the barb diameter of the main hook and the auxiliary hook, which can firmly hook the fish mouth and greatly reduce the phenomenon of hook slippage after the fish swallows the hook. As long as the fish bites the hook, it can be brought ashore with the hook, thereby improving the success rate of catching fish on the hook and ideally solving the shortcomings of single-hook fishing.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Embodiment 1: An anti-escape retractable fishhook, such as Figure 1-Figure 5 As shown, it includes a main hook 1, an auxiliary hook 2, a hook deployment member 3, a hook combination member 4, a hook line 5 and a torsion spring 6. The auxiliary hook 2 and the main hook 1 are hingedly connected to each other and can be automatically rotated and deployed. The main hook 1 and the auxiliary hook 2 are locked by the hook combination member 4. The hook line 5 includes a hook deployment segment 51, a hook tying segment 52 and a line pulling segment 53. The upper end of the line pulling segment 53 is fixedly connected to the fishing rod, and the lower end of the line pulling segment 53 is fixed with the hook tying segment 52 and the hook deployment segment 51. The hook tying segment 52 is connected to the main hook 1 or the auxiliary hook 2 or the hook deployment member 4. 3 is fixedly connected, the hook section 51 is fixedly connected to the hook member 4, and the length of the hook section 52 is greater than the length of the hook section 51; in this example, the hook member 3 is a fixed seat structure, and the fixed seat structure includes a bottom plate 30 and a torsion spring 6, and an upper folding edge 31, a middle folding edge 32, a lower folding edge 33, a torsion spring neck 34, a notch 35, a torsion pin hole 36 and an auxiliary hook hole 37 are provided on the bottom plate 30, and the upper folding edge 31, the middle folding edge 32 and the lower folding edge 33 are located on the bottom plate On the same side of the bottom plate 30, the torsion spring neck 34 is arranged in the middle of the bottom plate 30 and below the middle fold 32. The upper fold 31 and the middle fold 32 are respectively provided with collinearly distributed toggle pin holes 36, and the upper fold 31 and the lower fold 33 are respectively provided with collinearly distributed auxiliary hook holes 37. The auxiliary hook 2 includes an auxiliary hook handle 21, a stopper 22 and an upper limit cap 23. The auxiliary hook handle 21 of the auxiliary hook 2 can be rotatably mounted on the auxiliary hooks on the upper fold 31 and the lower fold 33. In the hook hole 37, the limiter 22 is fixed on the auxiliary hook handle 21, and the upper side of the limiter 22 is located at the position of the lower end surface of the middle folded edge 32, the upper limit cap 23 is fixed on the top of the auxiliary hook handle 21, the main hook handle 11 of the main hook 1 is fixed on the fixing seat, and the main hook handle 11 is parallel to the auxiliary hook handle 21; the toggle torsion spring 6 is installed on the torsion spring neck 34, and the upper leg 61 and the lower leg 62 of the toggle torsion spring 6 are arranged between the bottom plate 30 and the limiter 22 of the auxiliary hook 2;

[0029] The hook-combining member 4 is a toggle needle, comprising a needle rod 41, an upper limit position 42 and a lower limit position 43. The needle rod 41 is sleeved in the toggle needle hole 36 on the upper folding edge 31 and the middle folding edge 32. The upper limit position 42 is fixed to the top of the needle rod 41 to limit the needle rod 41 from falling. The lower limit position 43 fixes the middle position of the needle rod 41 to limit the upward movement of the needle rod 41. When the main hook 1 is combined with the auxiliary hook 2, the limiting member 22 on the auxiliary hook 2 presses the upper toggle leg 61 of the toggle torsion spring 6 to combine with the lower toggle leg 62. At this time, the lower section of the needle rod 41 realizes circumferential limitation on the limiting member 22 of the auxiliary hook 2.

[0030] When hooking a fish, the hook tips of the main hook 1 and the auxiliary hook 2 are wrapped with fish ear material. When the fish bites the hook, it will directly swallow the fish ear material and quickly swim away, at which time the hook line 5 will be pulled. Since the hook spreading member 3 is buckled on the hook spreading segment 51, and the length of the hook spreading segment 51 is less than the length of the hook tying segment 52, the hook spreading segment 51 is stressed earlier than the hook tying segment 52. The hook spreading segment 51 will pull the needle rod 41 of the toggle needle upward, so that the lower section of the needle rod 41 moves upward, thereby eliminating the circumferential limit of the limit plate 22 of the auxiliary hook 2, and the upper leg 61 and the toggle torsion spring 6 are moved upward. Driven by the lower leg 62, the auxiliary hook 2 will automatically rotate relative to the main hook 1 in the fish's mouth, so that the main hook 1 and the auxiliary hook 2 are hooked in the fish's mouth at the same time. No matter how fiercely the fish spits out the hook or struggles to get rid of the hook, the rapid rotation between the main hook 1 and the auxiliary hook 2 increases the hook barb diameter of the hook tip of the main hook 1 and the hook tip of the auxiliary hook 2, which can firmly hook the fish's mouth and greatly reduce the phenomenon of hook slippage after the fish swallows the hook. As long as the fish eats the hook, it can be brought ashore with the hook, which improves the success rate of catching fish and ideally solves the shortcomings of single-hook fishing.

[0031] Embodiment 2: The difference from Embodiment 1 is that the structure of the hook member 4 is changed. In this embodiment, the hook member 4 is a toggle fork, such as Figure 6 As shown, the toggle fork includes a needle rod 41, an upper limit position 42, a lower limit position 43 and an insertion fork 44. The needle rod 41 is sleeved in the toggle needle hole 36 on the upper folding edge 31 and the middle folding edge 32. The upper limit position 42 is fixed at the top of the needle rod 41, and the lower limit position 43 fixes the middle position of the needle rod 41. The insertion fork 44 is fixed at the lower end of the needle rod 41, and an insertion groove 45 is provided on the insertion fork 44. The toggle torsion spring 6 is wound on the torsion spring neck 34 of the fixed seat, and the upper toggle leg 61 and the lower toggle leg 62 of the toggle torsion spring 6 are arranged between the bottom plate 30 of the fixed seat and the limiting plate 22 of the auxiliary hook 2. When the main hook 1 is combined with the auxiliary hook 2, the limiting plate 22 on the auxiliary hook 2 presses the upper toggle leg 61 and the lower toggle leg 62 of the toggle torsion spring 6 to merge. At this time, the insertion fork 44 arranged at the lower end of the needle rod 41 realizes circumferential limitation on the limiting plate 22 of the auxiliary hook 2 through the insertion groove 45.

[0032] Embodiment 3: An anti-escape retractable fishhook, such as Figure 7-Figure 8As shown, it includes a main hook 1, an auxiliary hook 2, a hook-laying member 3, a hook-binding member 4 and a hook line 5. The auxiliary hook 2 and the main hook 1 are automatically rotated and unfolded by the hook-laying member 3. The main hook 1 and the auxiliary hook 2 are locked by the hook-binding member 4. The hook line 5 includes a lead line segment 53, a hook-tying segment 52 and a hook-laying segment 51. The upper end of the lead line segment 53 is fixedly connected to the fishing rod, and the lower end of the lead line segment 53 is fixedly connected to the hook-tying segment 52 and the hook-laying segment 51. The hook-tying segment 52 is fixedly connected to the main hook 1 or the auxiliary hook 2 or the hook-laying member 3, and the hook-laying segment 51 is fixedly connected to the hook-binding member 4. , the length of the hook section 52 is greater than the length of the unfolding hook section 51; in this example, the unfolding hook member 3 is a self-expanding hinge, and the hook member 4 is a locking fork, a baffle notch 81 is provided on the locking fork, the main hook handle 11 of the main hook 1 and the auxiliary hook handle 21 of the auxiliary hook 2 are respectively fixed on the left hinge 71 and the right hinge 72 of the self-expanding hinge, when the left hinge 71 and the right hinge 72 are in a merged state, the main hook 1 overlaps with the auxiliary hook 2, and the left hinge 71 and the right hinge 72 are inserted in the baffle notch 81 of the locking fork.
