Description

Technical Field

[0001] This invention belongs to the technical field of fishing auxiliary devices, specifically relating to a fishing aid device. Background Technology

[0002] A fishing rod is one of the most common fishing devices, utilizing the lever principle in physics. It consists of a rigid rod, a fulcrum, and a point where force is applied. In a lever system, when a force is applied to one end of the lever, it generates a rotational torque, producing a reaction force at the fulcrum, causing the lever to rotate around the fulcrum. The lever system of a fishing rod consists of the rod, fishing line, and hook. The rod itself acts as a lever, applying tension by moving the handle or reel to rotate the fishing line and transmitting this force to the hook. When a fish bites, the tension in the fishing line is transmitted downwards along the rod, causing it to bend. This bending deformation increases the length of the rod, thus increasing its lever arm. The longer the rod, the greater the lever arm and the greater the force generated. This leverage system uses effort-increasing force to deplete the fish's energy and utilizes elasticity to control and reduce the fish's explosive power. A typical fishing rod is a lever that requires effort, and this lever is adjustable, meaning it has either a rebound force or a drag force. The so-called "playing a fish" refers to the balanced state of this lever.

[0003] For both enthusiasts and professional anglers, the phenomenon of fish escaping from the hook is common. For example, the fish may not be able to swallow the hook completely, or the hook may not stay in the fish's mouth, reducing the tension of the fishing line and resulting in insufficient penetration depth, leading to the fish escaping. Alternatively, after penetrating the fish's mouth, the fish may struggle too much and tear its mouth to escape. Manually manipulating the hook requires tightening the fishing line when the fish reduces its pull and loosening it when it increases its pull. However, it is difficult to predict whether the fish will increase or decrease its pull during the rod swing, making it difficult to control the force exerted by the rod on the hook. This results in the hook not penetrating to the appropriate depth according to the fish's movement, leading to the problem of fish escaping. This is a technical problem that enthusiasts and professional anglers urgently need to solve. Summary of the Invention

[0004] This invention discloses a fishing aid device, which aims to solve the problem of insufficient hook penetration depth and easy fish escape in current fishing devices.

[0005] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0006] A fishing aid device includes: a first tube, a second tube, a third tube, and a telescopic tube; the second tube is telescopically connected inside the first tube, one end of the first tube has a connector, and the second tube can remain relatively stationary with respect to the first tube through the connector; a first magnet is provided at the end of the second tube near the connector; the third tube is sleeved inside the second tube, and a push rod is provided at the end of the third tube away from the first magnet; one end of the push rod is telescopically connected inside the third tube, and the other end of the push rod is detachably connected to the end of the second tube; a first limiting member is provided on the inner wall of the first tube, and the third tube... The end of the component near the first magnet can be limited by the first limiting member; the ends of the first tube, the second tube, the telescopic tube, and the push rod are all provided with through holes for the fishing line to pass through, and the telescopic tube is provided with a fixing member for fixing the fishing line; the telescopic tube is telescopically connected to the end of the third tube near the first magnet, the end of the telescopic tube near the first magnet is provided with a second magnet, and the other end of the telescopic tube is provided with a first snap-fit ​​member, and the second magnet and the first magnet can attract each other; the third tube and the two side walls of the telescopic tube are provided with a first elastic member, and the two ends of the first elastic member abut against the end of the third tube and the first snap-fit ​​member, respectively.

[0007] The fishing assist device of the present invention features a second tube that is telescopically connected to the first tube, allowing the second tube to retract into the first tube and thus approach the connector, or to partially extend out of the first tube and thus move away from the connector. A third tube is fitted inside the second tube, with a push rod at the end away from the first magnet. One end of the push rod is telescopically connected to the third tube, and the other end is detachably connected to the end of the second tube. By retracting the push rod into the second tube and detachably connecting it to the end of the second tube, the second tube can be driven to retract into the first tube, keeping it relatively stationary relative to the first tube through the connector. Furthermore, through holes for the fishing line are provided at the ends of the first tube, the second tube, the telescopic tube, and the push rod, allowing the fishing line to pass through the telescopic tube. A fixing member for securing the fishing line is provided inside the telescopic tube, allowing the fishing line to be positioned at the fixing member before exiting through the through holes of the telescopic tube and the push rod, and then connected to the reel-in end of the fishing rod. After a fish bites the hook, it pulls the fishing line towards one end of the hook. Since a section of the fishing line is positioned on the telescopic tube by the fixing member, force is transmitted to the fixing member, pulling the telescopic tube out of the third tube. On one hand, this causes the second magnet to continuously move closer to the first magnet. When the distance between the first and second magnets shortens to a certain extent, the first and second magnets attract each other, thus exerting a force on the telescopic tube to continue extending into the third tube. On the other hand, by setting the two ends of the first elastic member to abut against the end of the third tube and the first snap-fit ​​member respectively, as the telescopic tube extends into the third tube, the first snap-fit ​​member will squeeze the first elastic member, compressing it and generating an elastic restoring force opposite to the direction of the telescopic tube's extension. The elastic restoring force of the first elastic element increases with the degree of compression. When the fish loosens the fishing line, the tension on the fishing line decreases. Due to the elastic restoring effect of the first elastic element, the resultant force on the telescopic tube is transformed into the direction of retraction of the third tube, and transmitted to the hook through the fishing line. This causes the hook to be instantly subjected to a force opposite to the direction of the fish pulling the fishing line, allowing it to penetrate deeper into the fish's mouth. When the fish tries to escape and the pulling force is large, the telescopic column, due to the action of the first elastic element, can keep the telescopic column moving in the direction of the fish's pulling force, which can buffer the instantaneous pulling force when the fish escapes, thereby preventing the fish's mouth from being torn and escaping. This achieves a more secure hooking of the fish's mouth, making it less likely for the fish to get off the hook and reducing the probability of the fish escaping. Moreover, the operation only requires manually pushing and fixing the push rod before fishing, making it simple, convenient, and highly applicable.

[0008] Preferably, in the fishing aid device of the present invention, the connecting member is a third magnet; the third magnet and the first magnet are able to attract each other.

[0009] In a preferred embodiment of the fishing assist device of the present invention, by setting the connector as a third magnet, the magnetic attraction of the third magnet on the first magnet before the fish bites the hook can keep the second tube relative to the first tube stationary; thereby keeping the push rod, the second tube, and the third tube stationary relative to the first tube; and generating force before the second tube contacts the first tube, reducing the limitation on the size of the second tube and enhancing the adjustability and applicability of the device.

[0010] Preferably, the end of the push rod away from the third pipe is threaded to the second pipe and is provided with a first groove that can accommodate the side wall of the third pipe.

[0011] As a preferred embodiment of this solution, based on the detachable connection of the push rod to the second pipe fitting, the other end of the push rod is threadedly connected to the second pipe fitting. Before the fish bites, the push rod can be detachably fixed to the second pipe fitting, which is convenient for unscrewing during disassembly or maintenance. After the fish bites, the third pipe fitting is retracted through the telescopic tube, thereby pushing the push rod and the second pipe fitting as a whole to move outward from the first pipe fitting. This enhances the overall telescopic stability of the second pipe fitting and the push rod. The side wall of the third pipe fitting can be embedded in the first sliding groove. Compared with other detachable connections, the combination of the threaded connection of the push rod and the embedding of the third pipe fitting can reduce the failure rate and improve the performance of the device under the telescopic movement described in this invention.

[0012] Preferably, the third tube is provided with a second snap-fit ​​member at one end near the first magnet. The second tube is provided with a second sliding groove for the second snap-fit ​​member to slide axially. The second snap-fit ​​member can pass radially through the second sliding groove and snap onto the first limiting member.

[0013] As a preferred embodiment of this solution, by providing a second snap-fit ​​component, the portion of the third pipe fitting retracted into the second pipe fitting can be snapped into the first limiting component. Furthermore, a second sliding groove is provided, allowing the second snap-fit ​​component to slide axially within the groove. This ensures that the retraction of the second pipe fitting into the first pipe fitting is not obstructed by the second snap-fit ​​component, achieving the limitation of the third pipe fitting without affecting its extension and retraction. This ingenious design improves the coordination between the extension and retraction of the second pipe fitting and the limitation of the third pipe fitting, further enhancing the flexibility of the device, reducing the failure rate, and extending its service life.

[0014] Preferably, a second elastic element is provided between the two side walls of the second pipe fitting and the third pipe fitting; the second elastic element extends along the extension and retraction direction of the push rod; the end of the second elastic element away from the push rod is fixed to the third pipe fitting.

[0015] In a preferred embodiment of the fishing assist device of the present invention, the third tube is snapped into the first limiting member by the second snap-fit ​​member. The end of the second elastic member away from the push rod is fixed to the third tube. The end of the second elastic member near the push rod is compressed due to the retraction of the push rod. After the fish bites the hook, the telescopic tube pushes the push rod in the opposite direction and causes the second tube to extend out of the first tube, thereby lengthening the axial distance between the end of the third tube and the push rod. This releases the elastic restoring force of the second elastic member. Based on the elastic restoring force of the first elastic member, the push rod disengages from the second tube more quickly and withdraws rapidly, thereby increasing the reverse movement rate of the telescopic rod. This allows the fish hook to hook the fish's mouth more quickly and deeply, further reducing the probability of the fish escaping and improving the applicability of the device.

[0016] Preferably, in the fishing assist device of the present invention, a second limiting member is provided at the pipe opening of the first tube near the push rod end; the second limiting member is telescopically connected to the outside of the first tube, and the second limiting member is used to limit the end of the push rod away from the third tube to be outside the pipe opening of the first tube.

[0017] In a preferred embodiment of the fishing assist device of the present invention, the second limiting member is telescopically connected to the outside of the first tube, such as by a threaded connection. By screwing the second limiting member in, the other end of the push rod can extend further into the third tube, thereby compressing the first and second elastic elements to a greater extent. Combined with a connecting member with a greater force or a first magnet with stronger magnetism, it can withstand greater pulling force from the fish on the fishing line. Conversely, by unscrewing the second limiting member, the other end of the push rod can extend less into the third tube, thereby compressing the first and second elastic elements to a lesser extent. Combined with a connecting member with a smaller force and / or a first magnet with weaker magnetism, the impact force of the fishing hook in the fishing assist device of the present invention can be matched according to the pulling force of the fish. For example, when fishing for large fish, the second limiting member is screwed in; when fishing for small fish, the second limiting member is screwed out. This allows the fishing assist device to be adjusted for fishing fish of different sizes, increasing its functionality and enhancing its versatility.

[0018] Preferably, in the fishing assist device of the present invention, the second limiting member is provided with a connecting groove, which is used to fix the fishing line lug.

[0019] In a preferred embodiment of the fishing assist device of the present invention, by setting a connecting groove, the connection of the fishing assist device to the fishing line can be made more secure simply by fixing the fishing line lug, reducing the probability of the device detaching from the fishing line and enhancing the stability of the device in use.

[0020] Preferably, in the fishing assist device of the present invention, the connecting groove includes at least two symmetrically arranged on the outer wall of the first pipe fitting. The two connecting grooves can fix at least two fishing line lugs, allowing the fishing line to be pulled at the center of symmetry of the lugs. This reduces the probability that the fishing line cannot be pulled along the direction of sliding due to the angle between the lugs and the fishing line, further reducing the friction between the fishing line and the lugs, and enhancing the service life of both the lugs and the fishing line.

[0021] Preferably, in the fishing assist device of the present invention, a third limiting member is provided at one end of the third pipe near the second snap-fit ​​member, and a limiting ring is provided at the center of the third limiting member for the telescopic tube to pass through, and the outer wall of the limiting ring is fixedly connected to the third pipe by a connecting rib.

[0022] In a preferred embodiment of the fishing-assisting device of the present invention, by providing a third limiting member inside the third pipe, the telescopic tube can extend and retract under the support or limitation of the third limiting member, thereby reducing the possibility of radial displacement due to the sliding of the telescopic tube during extension and retraction, reducing the failure rate of the fishing-assisting device, and improving the performance of the fishing-assisting device.

[0023] Preferably, in the fishing assist device of the present invention, the second snap-fit ​​member is an annular shape with an outer diameter equal to that of the third tube, and the outer wall of the second snap-fit ​​member is provided with at least two protrusions, the protrusions being able to pass through the second sliding groove and snap onto the first limiting member in the direction of the retraction of the third tube.

[0024] In a preferred embodiment of the fishing-assisting device of the present invention, the second snap-fit ​​member is configured as an annular member, and the protrusion is provided, so that the protrusion can snap onto the first limiting member. During the sliding process of the second tube relative to the third tube, the protrusion can slide relative to the third tube in the second groove, which can limit the extension and retraction of the second tube. This reduces the probability of the second tube getting stuck and unable to extend or retract due to radial displacement during extension and retraction, reduces the friction between the second tube and the third tube during extension and retraction, lowers the failure rate of the fishing-assisting device, and further enhances the durability of the fishing-assisting device.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] Through the telescopic cooperation of the first, second, and third fittings and the push rod, and in conjunction with the interaction of the connector, the first magnet, and the second magnet, when the fish bites the hook and the pulling force on the hook decreases, the hook will be pushed deeper into the fish's mouth by the reverse force of the telescopic tube, making the hook more firmly hooked in the fish's mouth. When the impulse of the fish's pulling force on the hook is too large, the telescopic column moves with the pull of the fishing line, which can buffer the instantaneous pulling force of the fish, avoid the fish's mouth being torn, make it less likely for the fish to get off the hook and reduce the probability of the fish's mouth being torn, and make the hook more firmly hooked in the fish's mouth, which can reduce the probability of the fish getting away. Moreover, the operation only requires manually pushing and fixing the push rod before fishing, which is simple and convenient to operate and has strong applicability. Attached Figure Description

[0040] The following is combined Figures 1-9 The present invention will be described in detail below.

[0041] Example 1

[0042] like Figures 1-4As shown, the present invention provides a fishing-assisting device comprising: a first tube 1, a second tube 2, a third tube 3, and a telescopic tube 4; the second tube 2 is telescopically connected to the first tube 1, and one end of the first tube 1 is provided with a connector 91, allowing the second tube 2 to remain relatively stationary with respect to the first tube 1 via the connector 91; a first magnet 92 is provided at one end of the second tube 2 near the connector 91; the third tube 3 is sleeved within the second tube 2, and a push rod 8 is provided at the end of the third tube 3 away from the first magnet 92; one end of the push rod 8 is telescopically connected to the third tube 3, and the other end of the push rod 8 is detachably connected to the end of the second tube 2; a first limiting member 11 is provided on the inner wall of the first tube 1, and the third tube 4... The end of component 3 near the first magnet 92 can be limited to the first limiting component 11; the ends of the first tube 1, the second tube 2, the telescopic tube 4, and the push rod 8 are all provided with through holes 5 for the fishing line 0 to pass through, and the telescopic tube 4 is provided with a fixing component 41 for fixing the fishing line 0; the telescopic tube 4 is telescopically connected to the end of the third tube 3 near the first magnet 92, the end of the telescopic tube 4 near the first magnet 92 is provided with a second magnet 93, and the other end of the telescopic tube 4 is provided with a first snap-fit ​​component 42, and the second magnet 93 and the first magnet 92 can attract each other; the third tube 3 and the two side walls of the telescopic tube 4 are provided with a first elastic component 101, and the two ends of the first elastic component 101 abut against the end of the third tube 3 and the first snap-fit ​​component 42, respectively.

[0043] In this embodiment, the connector 91 can be a third magnet; the third magnet and the first magnet 92 can attract each other. Figure 2 As shown, the first tube 1 is provided with a fixedly connected connector 91 at the end away from the push rod 8. Preferably, the connector 91 can be set as a third magnet. The second tube 2 is provided with a fixedly connected first magnet 92 at the end near the third magnet. The first magnet 92 and the third magnet can attract each other.

[0044] In this embodiment, a second elastic element 102 is provided between the two side walls of the second pipe 2 and the third pipe 3; the second elastic element 102 extends along the extension and retraction direction of the push rod 8; the end of the second elastic element away from the push rod 8 is fixed to the third pipe 3.

[0045] Before the fish bites, the second elastic element 102 generates an elastic restoring force due to the compression of the push rod 8. After the fish bites, the telescopic tube 4, due to the elastic restoring force of the first elastic element 101, pushes the push rod 8 in the opposite direction at one end of the telescopic tube 4 with the first snap-fit ​​42. This causes the push rod 8 to be separated from the second tube 2 by the reverse force, thereby releasing the second elastic element 102. This allows the push rod 8 to exit the second tube 2 more quickly, thus achieving a faster reverse insertion speed into the fish's mouth, making the fish hook more firmly hook the fish's mouth, further reducing the probability of the fish escaping, and improving the applicability of the device.

[0046] Assembly and usage reference of this invention: Assemble the first elastic element 101 onto the third tube 3, then extend and retract the end of the telescopic tube 4 with the second magnet 93 to the third tube 3, then install one end of the push rod 8 inside the second tube 2, and connect the other end of the push rod 8 to the end of the second tube 2, then retract the end of the second tube 2 with the first magnet 92 into the first tube 1; connect one end of the fishing line 0 to the hook, and the other end of the fishing line 0 sequentially passes through the through hole 5 of the first tube 1, the through hole 5 of the second tube 2, and the through hole 5 of the telescopic tube 4 into the telescopic tube 4 and is fixed by the fixing element 41, then sequentially passes through the through hole 5 of the other end (right end) of the telescopic tube 4 and the push rod. The through hole 5 of 8 passes through, allowing the other end of the fishing line 0 to be connected to the reel end of the fishing rod. Before the hook is lowered into the water, the push rod 8 is pushed, causing the second tube 2 to retract into the first tube 1. At this time, the first magnet 92 gradually approaches the connector 91 (third magnet), and the connector 91 exerts a force on the first magnet 92. Alternatively, the third magnet can exert an attractive force F0 on the first magnet 92. The push rod 8 will gradually compress the second elastic element 102, causing the second elastic element 102 to exert a reverse elastic force F1 on the push rod 8. The device is designed such that F0 is greater than F1, so that the second tube 2 can remain relatively stationary with the first tube 1 through the action of the connector 91 (third magnet). At the same time, the attraction force (F2) of the first magnet 92 on the third magnet can drive the telescopic tube 4 to retract into the first tube 1. The movement of the telescopic tube 4 compresses the first elastic member 101, causing it to generate an elastic force F3 on the telescopic tube 4 in the opposite direction to F2. When F3 is greater than F2, the telescopic tube 4 will rebound and move away from the connector 91 (third magnet) until the first snap-fit ​​member 42 of the telescopic tube 4 comes into contact with the end of the push rod 8 and stops.

[0047] The working principle of this invention is as follows: After a fish bites the hook, it pulls on the fishing line 0 towards one end of the hook. The pulling force of the fish pulling on the fishing line 0 is represented by F4. F4 is transmitted to the telescopic tube 4 through the fixing member 41. Under the action of the pulling force of F4, the telescopic tube 4 continues to extend axially to the end of the third tube 3, and compresses the first elastic member 101 again through the action of the first snap-fit ​​member 42, so that the first elastic member 101 generates an elastic restoring force F3 on the telescopic tube 4 again. During this process, the second magnet 93 will move closer to the first magnet 92. When the distance between the second magnet 93 and the first magnet 92 is shortened to a certain extent, the first magnet 92 generates an attractive force F2 on the second magnet 93 again. At this moment, if the fish suddenly loses its pull on the hook while escaping, the restoring force F3 of the first elastic element 101, the restoring force F1 of the second elastic element 102, and the attraction force F2' of the second magnet 93 on the first magnet 92 are greater than the resultant force of the fishing line 0's tension F4 and the attraction force F0 of the first magnet 92 on the second magnet 93, which can be expressed by Equation 1 as: F3 + F1 + F2' > F4 + F0. This causes the resultant force on the telescopic tube 4 to change towards the direction of retraction of the third tube 3. During the process, F0 gradually decreases until it disappears. At this time, the force on the telescopic tube 4 is opposite to the pull force F4 of the fish on the hook. The hook is instantly driven by the telescopic tube 4 to penetrate deeper into the fish's mouth, so that the hook can hook the fish's mouth more firmly. If the impulse of the pull force of the fish on the hook is large at one moment, the telescopic tube 4 extends along the fishing line 0 in the direction of the pull force of the fish, which buffers the instantaneous impulse of the hook, thereby preventing the hook from penetrating too quickly and tearing the fish's mouth. It can also make the hook penetrate the fish's mouth properly and more firmly, reducing the probability of the fish escaping.

[0048] It should be noted that the ends of the first fitting 1, the second fitting 2, the telescopic tube 4, and the push rod 8 are all provided with through holes 5 for the fishing line 0 to pass through. This means that the through holes 5 are provided at the ends of the fittings where the fishing line 0 needs to pass through. The same through holes 5 are provided in different components based on the actual needs of threading the fishing line 0; the only difference is the location of the through holes 5. Figure 2 As shown, the left ends of the first pipe fitting 1, the second pipe fitting 2, and the telescopic pipe 4 are all provided with through holes 5 for the fishing line 0 to pass through. The right ends of the telescopic pipe 4 and the push rod 8 are also provided with through holes 5 for the fishing line 0 to pass through. The telescopic pipe 4 is provided with a fixing member 41 for fixing the fishing line 0. The method of implementation is as follows: with the telescopic pipe 4 as the center, one end of the fishing line 0 passes through the through hole 5 of the telescopic pipe 4 and is connected to the fish hook. The other end is fixed in the telescopic pipe 4 by the fixing member 41. Then, it passes through the through hole 5 at the right end of the telescopic pipe 4 and the push rod 8, and exits and is connected to the take-up end of the fishing line 0. It should be noted that in this embodiment, the fixing member 41 can be set as a hollow cylinder with an outer diameter smaller than the through hole 5 in the telescopic pipe 4. The fishing line 0 is positioned at the end of the hollow cylinder by the fixing member 41, so that the fishing line 0 does not slide relative to the hollow cylinder. The hollow cylinder is fixedly connected in the telescopic pipe 4, thereby fixing the fishing line 0.

[0049] It should be noted that the term "telescopic" is understood as axial sliding relative to each other under the action of force, so that one end extends out or retracts into the tube. For example, if the second tube 2 is telescopically connected to the first tube 1, it is understood that one end of the second tube 2 extends into the first tube 1 and can slide axially relative to the first tube 1 under the action of force, so as to extend out or retract into the first tube 1. In this embodiment, each of the tubular components can be a cylindrical tube.

[0050] It should be noted that the other end of the push rod 8 is detachably connected to the end of the second pipe fitting 2. Here, the detachable connection can be a threaded connection, which means that the outer wall of the push rod 8 and the inner wall of the second pipe fitting 2 are provided with mutually cooperating threads. The push rod 8 can be screwed into or out of the second pipe fitting 2 along the threads under axial force.

[0051] It should be noted that the first groove 81 is understood to be a groove whose width is equivalent to the thickness of the tank wall of the third pipe 33. After the push rod 8 retracts into the second pipe 2 and pushes the second pipe 2 into the first section of the pipe, the first groove 81 of the push rod 8 can just make the third pipe 3 be connected to the first groove 81 of the push rod 8 with clearance fit.

[0052] In this embodiment, the lengths of the second pipe fitting 2, the third pipe fitting 3, and the push rod 8 are set to be mutually matched, such that the length of the second pipe fitting 2 is greater than the sum of the lengths of the push rod 8 and the third pipe fitting 3. This allows the second pipe fitting 2 to retract into the first pipe fitting 1, with reference to... Figure 4 As shown, the ends of the third pipe 3 and the push rod 8 can be connected by a clearance fit through the first sliding groove 81.

[0053] Another implementation of the connector 91 described in this invention is as follows: Figure 9 As shown, the connector 91 is a half-sleeve with an inner diameter equivalent to the outer diameter of the second pipe fitting 2. The second pipe fitting 2 extends into the rear end of the first pipe fitting 1 and is sleeved in the half-sleeve. The half-sleeve is detachably connected to the first pipe fitting 1. The second pipe fitting 2 and the half-sleeve are interference-fitted to generate friction, thereby achieving a temporary connection with the first pipe fitting 1. When the friction between the second pipe fitting 2 and the half-sleeve is less than the restoring force of the first elastic member 101, the second pipe fitting 2 and the half-sleeve move relative to each other in the direction in which the second pipe fitting 2 extends, thereby separating the second pipe fitting 2 from the first pipe fitting 1 and achieving a detachable temporary connection.

[0054] In this embodiment, as Figure 2 , Figure 5 and Figure 6As shown, the inner wall of the first tube 1 is provided with a first limiting member 11, the second tube 2 is provided with a second sliding groove 21 along the extension and retraction direction of the push rod 8, and the third tube 3 is provided with a second snap-fit ​​member 31 at one end near the first magnet 92. The second snap-fit ​​member 31 can pass through the second sliding groove 21 and snap-fit ​​onto the first limiting member 11 along the retraction direction of the third tube 3.

[0055] It should be noted that the reference Figure 5 and Figure 6 As shown, the second snap-fit ​​member 31 can partially pass through the second slide groove 21 by setting a protrusion 311. The first limiting member 11 is set as a convex ring protruding towards the inner wall of the first tube 1. The protrusion 311 can abut against the convex ring to achieve snap-fit ​​on the side of the convex ring away from the third magnet, and achieve snap-fit ​​along the direction of the retraction of the third tube 3. Since it is a single-sided abutment between the protrusion 311 and the convex ring, when the third tube 3 extends out of the second tube 2 or the first tube 1 moves, the first limiting member 11 will not block the second snap-fit ​​member 31, so as not to block the extension and movement of the third tube 3.

[0056] It should be noted that the first pipe fitting 1, the second pipe fitting 2, and the telescopic pipe 4 can be made of plastic or metal, preferably stainless steel. The third magnet, the first magnet 92, and the second magnet 93 can be bonded to the first pipe fitting 1, the second pipe fitting 2, and the telescopic pipe 4 respectively with adhesive, so that the third magnet, the first magnet 92, and the second magnet 93 can be fixed.

[0057] In this embodiment, the fishing assist device of the present invention has a second limiting member 12 at the end of the first tube 1 near the push rod 8; the second limiting member 12 is telescopically connected to the outside of the first tube 1, and the second limiting member 12 is used to limit the end of the push rod 8 away from the third tube 3 to be outside the opening of the first tube 1.

[0058] In this embodiment, the second limiting member 12 can be a threaded sleeve threaded to the first tube 1. Unscrewing it increases the limiting distance to the top of the push rod 8, while screwing it in decreases the limiting distance. By telescopically connecting the second limiting member 12 to the outside of the first tube 1 (e.g., by threading it to the outside of the first tube 1), screwing in the second limiting member 12 allows the other end of the push rod 8 to extend further into the third tube 3, thereby compressing the first elastic member 101 and the second elastic member 102 to a greater extent. Combined with a stronger third magnet or a stronger first magnet 92, it can withstand greater tension from the fish on the fishing line 0. Conversely, unscrewing the second limiting member 12 allows the push rod 8 to extend further into the third tube 3. The other end of the rod 8 extends into the third tube 3 by a shorter length, thus compressing the first elastic element 101 and the second elastic element 102 to a lesser extent. Combined with the third magnet and / or the first magnet 92 with a smaller magnetic field strength, the impact force of the fishing hook of the fishing aid device of the present invention can be matched according to the pulling force of the fish. For example, when fishing for large fish, the second limiting element 12 is screwed in, and when fishing for small fish, the second limiting element 12 is screwed out. This allows the fishing aid device to be adjusted for fishing fish of different sizes, increasing the functionality of the fishing aid device and enhancing its versatility.

[0059] In this embodiment, the fishing-assisting device of the present invention, such as... Figure 1 and Figure 8 As shown, the second limiting member 12 is provided with a connecting groove 121, which is used to fix the fishing line 0 lifting lug. By setting the connecting groove 121, it is only necessary to fix the fishing line 0 lifting lug to make the connection of the fishing assist device on the fishing line 0 more secure, reduce the probability of the device detaching from the fishing line 0, and enhance the stability of the device. It should be noted that by inserting the side of the fishing line 0 lifting lug into the connecting groove 121 and fixing it with bolts, pins, etc., the fishing line 0 lifting lug can be fixed to the connecting groove 121.

[0060] In this embodiment, the fishing-assisting device of the present invention, such as... Figure 1 and Figure 8 As shown, the connecting groove 121 includes at least two symmetrically arranged on the outer wall of the first pipe fitting 1. The two connecting grooves 121 can fix at least two fishing line 0 lugs, so that the fishing line 0 is pulled at the center of symmetry of the fishing line 0 lugs. This reduces the probability that the fishing line 0 and the fishing line 0 lugs cannot be pulled along the direction of the fishing line 0 due to the angle, and can further reduce the friction between the fishing line 0 and the fishing line 0 lugs, thereby enhancing the service life of the fishing line 0 lugs and the fishing line 0.

[0061] In this embodiment, as Figure 7As shown, in the fishing-assisting device of the present invention, a third limiting member 32 is provided at one end of the third tube 3 near the second connecting member 31. A limiting ring 321 for the telescopic tube 4 to pass through is provided at the center of the third limiting member 32. The outer wall of the limiting ring 321 is fixedly connected to the third tube 3 by a connecting rib. By providing the third limiting member 32 inside the third tube 3, the telescopic tube 4 can extend and retract under the support or limitation of the third limiting member 32, reducing the possibility of radial displacement due to the sliding of the telescopic tube 4 during extension and retraction, thus reducing the failure rate of the fishing-assisting device and improving its performance.

[0062] In this embodiment, the fishing-assisting device of the present invention has a second locking member 31 that is annular with an outer diameter equal to that of the third tube 3. The outer wall of the second locking member 31 has at least two protrusions 311. These protrusions 311 can pass through the second sliding groove 21 and engage with the first limiting member 11 along the direction of the retraction of the third tube 3. By setting the second locking member 31 as an annular member and providing the protrusions 311, the protrusions 311 can engage with the first limiting member 11. During the sliding process of the second tube 2 relative to the third tube 3, the protrusions 311 can slide relative to each other within the second sliding groove 21, thus providing a limiting extension function for the second tube 2. This reduces the probability of the second tube 2 becoming stuck due to radial displacement during extension, reduces friction between the second tube 2 and the third tube 3 during extension, lowers the failure rate of the fishing-assisting device, and further enhances its durability.
