Description

Technical Field

[0001] This utility model relates to the field of fishing technology, and in particular to a biomimetic lure for lure fishing that still swings and makes a sound even when no external force is applied. Background Technology

[0002] The current drawback of artificial lures used by lure enthusiasts is that whenever the angler performs a jerking motion, the lure immediately loses its apparent life-like characteristics after each jerk and the pulling motion is stopped. In other words, as soon as the angler stops pulling, the lure immediately becomes motionless and loses its biomimetic attraction. To address this shortcoming, a spinning top is incorporated into the lure's body. Utilizing the jerking motion frequently used by anglers, the jerk is rotated by the pulling force of the jerk. Taking advantage of the inherent property of the spinning top to remain rotating until its rotational inertia is exhausted, the lure continues to exhibit some life-like characteristics of a real lure, such as swaying, shaking, and emitting impact and friction sound waves, even after the angler stops jerking. Summary of the Invention

[0003] The purpose of this invention is to provide a biomimetic lure for lure fishing that continues to swing and make a sound even without external force. It is characterized by comprising a shell, a rotating gyroscope, a gravity switch, a return weight, and a main line. The rotating gyroscope is horizontally positioned within the gyroscope shaft holes on both sides of the shell. The return weight is located in the return weight compartment at the top of the shell. The gravity switch is located at the gravity switch fixing point at the bottom of the shell. The main line is located at the main line connection point above the front end of the head of the shell. When the angler casts the lure into the water, the gravity of the return weight causes the lure to flip into a position with its head backward, tail forward, belly up, and back down. This causes the gravity switch to flip above the rotating gyroscope on the lure, causing the gravity rotation plate to droop and lock into the serrated edge groove due to its own weight. When the angler quickly lifts the rod each time they jerk the line, the main line engages with the lure's main line. The traction applied at the connection point causes the lure's head to rotate from below to in front of it. Simultaneously, the gravity switch's rotating plate pushes against the serrated edge groove of the spinning top, causing it to begin rotating. The rotation of the lure, once in the water, causes it to rotate under gravity to the return weight below it, which then flips back to the top of the outer shell. When the angler stops pulling, the return weight's gravity returns the outer shell to a head-back, tail-forward position, awaiting the angler's next jerk. At this point, due to the inherent properties of the spinning top, the gyroscope disc continues to rotate until its rotational inertia is exhausted. The vibration device on the gyroscope disc causes the lure to exhibit a biomimetic phenomenon of wriggling, shaking, and simultaneously emitting impact and friction sound waves, even without external force.

[0004] The outer shell consists of a main body, gyroscope shaft holes, a return weight compartment, a gravity switch fixing point, a main line traction groove, and a main line connection point. The main body is made of rigid material with a closed internal space, and its shape mimics the shape of the target baitfish. The diameter of the internal space is larger than the diameter of the gyroscope disc plus the height of the gravity switch's rotation plate limiter. The gyroscope shaft holes are two corresponding holes located within the main body. Besides the gravity of the return weight, the two side chambers on either side of the main body's front and rear center lines have an inner diameter larger than the diameter of the gyroscope shaft, and the distance between the deepest points of the two holes is greater than the length of the gyroscope shaft. Their function is to hold the rotating gyroscope within the two shaft holes. When the angler casts the lure into the water, the gravity of the return weight causes the lure to flip. The lure is positioned with its head at the back, tail at the front, abdomen on top, and back at the bottom. This causes the gravity switch to flip above the spinning top of the lure, causing the gravity plate to droop and lock into the serrated edge groove due to its own weight. When the angler jerks the rod and pulls the main line, the gravity plate of the gravity switch, now suspended above the main body of the casing, pushes the serrated edge groove on the spinning top's disc, causing the disc to rotate the spindle within the spindle's shaft hole. The return weight compartment is located on the upper part of the casing, slightly forward above the vertical line connecting the two spindle shaft holes. The purpose of placing the return weight compartment on the upper part of the casing is to ensure that the upper part of the lure is heavier than the lower part, allowing the lure to enter the water more easily. After the lure is submerged or pulled to the point where its head is in front and its tail is behind, immediately flip it over so that the head is behind, the tail is in front, the back is below, and the belly is above. The purpose of placing the return weight chamber slightly forward and above the vertical line connecting the two gyroscope shaft holes is that, since the two gyroscope shaft holes are correspondingly located within the main body of the outer shell, the return weight is placed in the chamber on either side of the front and rear center lines of gravity, excluding the weight of the return weight. This allows the lure to rotate downwards from the front under the weight of the return weight, ensuring the main line smoothly winds into the main line guide groove during the lure's downward rotation. This guide groove then defines the traction trajectory of the main line for each subsequent pull by the angler. When the rod pulls the lure along the main line, the traction force applied by the main line to the main line connection point located below the head of the casing, and the traction trajectory defined by the main line traction groove, causes the lure's head to rotate from below to in front of the lure along the trajectory direction of the main line traction groove below the lure. This allows the lure to smoothly reverse longitudinally, causing the gravity switch's gravity rotation plate, located above the main casing, to push the oblique serrated edge groove on the circumference of the gyroscope disk. This causes the gyroscope disk to drive the gyroscope shaft to begin rotating within the gyroscope shaft hole. The gravity switch fixing point is located at the lower part of the casing, slightly forward of the vertical line connecting the two gyroscope shaft holes. It consists of a rotation plate shaft fixing point and a rotation plate limit lock fixing point, with the rotation plate shaft fixing point located before the rotation plate limit lock fixing point.This is the fixing point for the movable shaft of the rotating plate. The fixing point for the rotating plate limit clip is the fixing point for setting the rotating plate limit clip. The function of setting the rotating plate shaft fixing point before the rotating plate limit clip fixing point is to allow the movable shaft of the rotating plate to pass through the rotating plate shaft hole of the gravity rotating plate, and then fix the gravity rotating plate to the rotating plate shaft fixing point through its movable shaft. Then, the rotating plate limit clip is set at the rotating plate limit clip fixing point. When the lure is cast into the water, or when the angler pulls the lure to the head-forward and tail-back position and stops pulling, the weight of the return weight causes the lure to immediately flip, so that the lure is head-back, tail-forward, back-down, and belly-up. At this time, the rotating plate limit clip is in front of the gravity rotating plate. The next time the angler... The pulling force applied to the lure is located at the mainline connection point below the lure's head. When the mainline is pulled by the angler, following the trajectory defined by the mainline traction groove, the mainline connection point rotates forward from directly below the lure. This causes the gravity plate, which sags under its own weight, to be stopped by the plate's limiting clip. Because the end of the gravity plate, suspended above the spinning top, is within the serrated edge groove, the gravity plate can only push the serrated edge groove, causing the spinning top to begin rotating with the lure. The mainline traction groove, located from the mainline connection point to the tail above the lure's head, restricts the mainline's traction trajectory. It's a groove that pulls the lure's head downwards longitudinally through the mainline connection point. The function of the mainline traction groove is... Because the mainline traction groove is a recessed area extending from the mainline connection point to the tail of the outer casing, when the lure is cast into the water, or when the angler pulls the lure until the head is forward and the tail is backward, the return weight is located in the upper part of the outer casing, above and forward of the vertical line connecting the two gyroscope shaft holes. The weight of the return weight forces the lure to rotate downward from the front, causing the mainline to wind clockwise around the mainline traction groove from the mainline connection point. When the angler quickly lifts the rod each time they jerk the rod, the traction force exerted by the mainline on the mainline connection point (located below the head of the outer casing) restricts the mainline's trajectory, forcing the lure to rotate downward from the head connection point. The lure's head turns from below to front, causing the gravity plate suspended above the spinning top inside the lure's shell to rotate. The mainline connection point is located above the front of the lure's head, connecting to the mainline. This placement ensures that after the lure is cast into the water, or after the angler pulls it to a head-forward, tail-back position and stops pulling, the weight of the returning counterweight forces the lure to rotate downwards. After this rotation, the lure's head is back, tail is front, back is down, and belly is up. With the mainline connection point below the front of the lure's head, it's easy to apply a reverse pull through the mainline, causing the lure to rotate downwards.

[0005] A spinning top is a gyroscope horizontally mounted in gyroscope shaft holes on both sides of its outer casing. It consists of a gyroscope disk and a gyroscope shaft. The gyroscope disk is a disc with a diameter smaller than the inner diameter of the area where the gyroscope disk rotates within the outer casing minus the length of the swivel plate limiter, and a thickness smaller than the width of the inner cavity where the gyroscope disk is located. It comprises the gyroscope disk body, a serrated edge groove, and a shaking device. The gyroscope disk body is a disc made of a heavy material. Its function is to utilize its high density and the small fulcrum of the gyroscope shaft to allow the gyroscope disk body, once rotating around the gyroscope shaft, to continue rotating for a period of time due to its inertia caused by its weight, even after external force is stopped. The serrated edge groove is a serrated groove set on the circumference of the gyroscope disk body. The shape of the serrated edge groove is such that the depth of the force-bearing side of the serrated edge groove (the distance from the tangent point of the circumference of the gyroscope disk body to its center) is greater than the length of the gravity rotating plate body minus the length of the rotating plate limiter, and the width is greater than the thickness of the gravity rotating plate. The function of the serrated edge groove is: firstly, when the lure is cast into the water, or when the angler pulls the lure to head-forward and tail-backward and stops pulling, the weight of the return weight causes the lure to flip downward from the front. After the lure is flipped, its position is head-back, tail-forward, back-down, and belly-up. At this time, the gravity rotating plate is suspended inside the outer shell body by its own weight. The gyroscope's main body is located in the serrated edge slot above the main body. When the angler quickly pulls the rod to move the lure, the traction force applied by the main line to the lure's connection point causes the lure's head to rotate from below to in front, creating a pushing force on the serrated edge slot by the gravity rotating plate. This causes the gyroscope to begin rotating. Secondly, when the angler stops pulling, the lure stops moving forward and returns to its original position via its return weight. The gravity rotating plate returns to its position before the angler pulled the lure, hanging above the serrated edge slot. At this point, the gyroscope continues to rotate due to its inertia. Since the direction of rotation of the gyroscope is opposite to the direction of the gravity rotating plate (where there is no limiting stop), the serrated edge slot continues to rotate. As the toothed edge of the lure rotates, it continuously strikes the gravity-driven rotating plate suspended above it, producing a slight impact sound to attract the attention of target fish. The shaking device, a tiny counterweight located on one side of the gyroscope body, disrupts the balance of the gyroscope body around its axis. Its function is to cause slight instability in the gyroscope's rotation when it is driven to spin, as its small weight slightly disrupts the balance of the gyroscope body around its axis, but this does not significantly affect the gyroscope's rotation time, causing the entire lure to shake. Additionally, the rotation of the gyroscope generates sound waves due to friction between the gyroscope axis and its hole.To achieve the biomimetic effect of the dummy still exhibiting shaking and emitting frictional sound waves when it stops, the gyroscope shaft is a metal shaft with a diameter smaller than the inner diameter of the gyroscope shaft hole and a length smaller than the distance between the deepest points of the two gyroscope shaft holes located on both sides of the outer shell. The function of the gyroscope shaft is to cause the gyroscope disk to rotate through the two gyroscope shafts located on both sides of the outer shell.

[0006] The gravity switch consists of a gravity rotating plate, a rotating plate movable shaft, and a rotating plate limiter. The gravity rotating plate is composed of a gravity rotating plate body and a rotating plate shaft hole. The gravity rotating plate body is made of rigid material, with a length less than the distance from the rotating plate shaft hole to the bottom of the oblique serrated edge groove, but greater than the distance from the rotating plate shaft hole to the edge of the oblique serrated edge groove. Its width is equal to the thickness of the gyroscope body, and its thickness is less than the width of the bottom of the oblique serrated edge groove. The rotating plate movable shaft is located within the rotating plate shaft fixing point at the gravity switch's fixing point, and its diameter is smaller than the... The metal shaft with the inner diameter of the rotating plate shaft hole; the rotating plate limiter is a right-angled triangle plate with a height less than the distance from the circumference of the oblique sawtooth edge groove to the rotating plate shaft fixation point, set on the rotating plate limiter fixing point. Its right-angled side is set on the side adjacent to the main body of the gravity rotating plate. The function of the gravity switch is that when the lure is cast into the water, or when the angler pulls the lure to the head-forward and tail-back position and stops pulling, the lure is reversed by the gravity of the return weight. After the lure is reversed, its posture is that the head is back, the tail is forward, the back is down, and the abdomen is up. At this point, the gravity gyroscope plate is suspended in the serrated edge slot above the gyroscope. When the main line is pulled by the angler along the trajectory defined by the main line traction groove in the direction of force on the main line, and the main line connection point rotates from directly below the lure to the front, the gravity gyroscope plate, which sags due to its own weight, is stopped by the gyroscope plate limiter. This forces the gravity gyroscope plate to push the serrated edge slot, causing the gyroscope disc to begin rotating with the lure's outer shell. When the angler stops tackling and lifts the rod, the gyroscope disc continues to rotate due to its inertia, thus driving the gyroscope. The purpose of rotation is that, because the limiter of the rotating plate is set in the opposite direction to the rotation of the gyroscope, the rotation of the gyroscope is not obstructed by the gravity rotating plate. During the rotation of the gyroscope, since the length of the gravity rotating plate is greater than the distance from the fixed point of the rotating plate axis to the circumference of the oblique serrated edge groove, the edge of the oblique serrated edge groove hits the gravity rotating plate, causing the gravity rotating plate to tilt backward under force. Then, due to its own weight, it droops again, causing the oblique serrated edge groove to continuously hit the gravity rotating plate, emitting impact sound waves to attract the attention of the target fish.

[0007] The return weight is made of metal and consists of a weight with a density greater than water and a volume equal to that of the return weight chamber. Its function is to cause the lure to flip over when it is cast into the water or when the angler pulls it to the point where the head is in front and the tail is behind. After the lure has flipped over, its head is behind, its tail is in front, its back is down, and its belly is up, preparing it for the angler's next jerk and pull.

[0008] The main line is a fishing line with a diameter suitable for the lure.

[0009] The fish hook is a fish hook that is the right size for the lure.

[0010] The principle and function of biomimetic lures that continue to swing and make sounds even when no external force is applied:

[0011] I. This utility model utilizes the inherent property of a rotating gyroscope that it can remain in a rotating state before its rotational inertia is exhausted. This allows the gyroscope inside the lure to continue rotating even after the angler stops pulling the rod and the lure loses external force during lure fishing. This ensures that the lure still exhibits some vital signs of a real lure, such as wriggling, shaking, and emitting impact and friction sound waves.

[0012] Second, by utilizing the buoyancy property of water, the lure is designed with a buoyancy structure that reverses immediately after the traction stops, so that the lure exhibits opposite postures when being tractioned and when the traction stops. The traction distance generated by these different body positions is used to drive the rotating gyroscope to rotate.

[0013] Third, by utilizing the principle of gravity causing objects to hang, the gravity switch plate on the outer shell is designed to suspend the gyroscope in a serrated edge slot on the circumference of the gyroscope when the lure is in a stopped state. This achieves the purpose of driving the gyroscope to rotate simply by pulling the lure, while avoiding the cumbersome process and unnecessary costs of setting up a separate switch.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, this utility model is implemented in the following way:

[0028] Its features include an outer shell 1, a rotating gyroscope 2, a gravity switch 3, a return weight 4, and a main line 5. The rotating gyroscope 2 is horizontally positioned within the gyroscope shaft holes 7 on both sides of the outer shell 1. The return weight 4 is positioned within the return weight chamber 8 at the top of the outer shell 1. The gravity switch 3 is positioned at the gravity switch fixing point 9 at the bottom of the outer shell 1. The main line 5 is positioned at the main line connection point 11 above the front end of the head of the outer shell 1. When the angler casts the lure into the water, the gravity of the return weight 4 causes the lure to flip so that its head is behind, its tail is in front, its belly is on top, and its back is below. This causes the gravity switch 3 to flip above the rotating gyroscope 2 of the lure, causing the gravity rotation plate 19 to droop and lock into the oblique serrated edge groove 17 due to its own weight. When the angler quickly lifts the rod each time they jerk the line, the traction force applied by the main line 5 to the main line connection point 11 of the lure causes the lure to... The head of the lure rotates from below to in front of the lure. At the same time, due to the pushing force of the gravity rotation plate 19 of the gravity switch 3 on the oblique sawtooth edge groove 17 of the rotating top 2, the rotating top 2 starts to rotate. Due to the rotation of the lure being pulled, after the lure enters the water, it rotates to the return weight 4 below the lure due to gravity, and then reverses to the top of the outer shell 1. When the angler stops pulling, under the action of the gravity of the return weight 4, the outer shell 1 returns to the state with the head in the back and the tail in the front, waiting for the angler's next traction process. At this time, due to the inherent properties of the rotating top 2, the top plate 14 is still rotating before its rotational inertial power is exhausted. Under the action of the shaking device 18 set on the top plate 14, the lure exhibits a biomimetic phenomenon of wriggling, shaking and emitting impact and friction sound waves without the action of external force.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12As shown, the outer shell 1 consists of an outer shell body 6, a gyroscope shaft hole 7, a return counterweight chamber 8, a gravity switch fixing point 9, a main line traction groove 10, and a main line connection point 11. The outer shell body 6 is made of rigid material with a closed internal space, and its shape imitates the shape of the target baitfish. The diameter of the internal space is larger than the diameter of the gyroscope disk 14 plus the height of the rotation plate limit card 21 of the gravity switch 3. The gyroscope shaft hole 7 consists of two corresponding holes set inside the outer shell body 6. Apart from the gravity of the return counterweight 4, the two side chambers on the front and rear center lines of the outer shell body 6 are shaft holes with an inner diameter larger than the diameter of the gyroscope shaft 15, and the distance between the deepest points of the two holes is larger than the length of the gyroscope shaft 15. Their function is to set the rotating gyroscope 2 through its gyroscope shaft 15 between the two gyroscopes. Inside the shaft hole 7, when the angler casts the lure into the water, the weight of the return weight 4 causes the lure to flip so that its head is back, tail is front, belly is up, and back is down. This causes the gravity switch 3 to flip above the gyroscope 2 of the lure, causing the gravity rotation plate 19 to droop and get stuck in the serrated edge groove 17 due to its own weight. When the angler pulls the rod and lifts the main line 5, the gravity rotation plate 19 of the gravity switch 3, which is now suspended above the outer shell 6, pushes the serrated edge groove 17 on the gyroscope disk 14 of the gyroscope 2, causing the gyroscope disk 14 to drive the gyroscope shaft 15 to start rotating inside the gyroscope shaft hole 7. The return weight chamber 8 is located on the upper part of the outer shell 1, above and forward of the vertical line connecting the two gyroscope shaft holes 7. It is where the return weight is located. The purpose of placing the return weight compartment 8 in the upper part of the outer shell 1 is to ensure that when the return weight 4 is placed in the return weight compartment 8, the upper part of the lure is heavier than the lower part. This allows the lure to flip immediately after entering the water or being pulled to the point where the head is in front and the tail is behind, with the head behind, the tail in front, the back below, and the abdomen above. The purpose of placing the return weight compartment 8 slightly forward and above the vertical line connecting the two gyroscope shaft holes 7 is because the two gyroscope shaft holes 7 are correspondingly located on the side walls of the front and rear center lines of gravity within the outer shell 6, excluding the weight of the return weight 4. Therefore, placing the return weight 4 in the return weight compartment 8 slightly forward of the front and rear center lines of gravity of the outer shell 6 ensures that the lure is more subdued by the weight of the return weight 4. Under the influence of the main line, the lure rotates downwards from the front, allowing the main line 5 to smoothly wind into the main line traction groove 10 during the lure's downward rotation. This ensures that when the angler pulls the main line 5 again, the main line traction groove 10 defines the traction trajectory of the main line 5. Each time the angler quickly lifts the rod to pull the lure, the traction force applied by the main line 5 to the main line connection point 11 located below the head of the outer shell 1, and the traction trajectory defined by the main line traction groove 10, causes the head of the lure to rotate from below to in front of the lure along the trajectory direction of the main line traction groove 10 below the lure. This allows the lure to smoothly reverse longitudinally, causing the gravity switch 3's gravity rotation plate 19, which is located above the outer shell 6, to push the oblique serrated edge groove 17 on the circumferential edge of the gyroscope disk 14.The gyroscope disk 14 drives the gyroscope axis 15 to begin rotating within the gyroscope axis hole 7. The gravity switch fixing point 9 is located at the lower part of the outer casing 1, slightly forward below the vertical line connecting the two gyroscope axis holes 7. It consists of a rotary plate axis fixing point 12 and a rotary plate limit clip fixing point 13. The rotary plate axis fixing point 12 is located before the rotary plate limit clip fixing point 13 and serves as the fixing point for the rotary plate movable axis 20. The rotary plate limit clip fixing point 13 is the fixing point for the rotary plate limit clip 21. The function of the rotary plate axis fixing point 12 being located before the rotary plate limit clip fixing point 13 is to allow the rotary plate movable axis 20 to pass through the rotary plate axis hole 23 of the gravity rotary plate 19, and then fix the gravity rotary plate 19 to the rotary plate axis 20 via its rotary plate movable axis 20. After fixing point 12 on the plate shaft, the rotating plate limiter 21 is then set at the rotating plate limiter fixing point 13. When the lure is cast into the water, or when the angler stops pulling the lure when the head is in front and the tail is behind, the lure immediately flips due to the gravity of the return weight 4, so that the lure is head behind, tail in front, back down, and belly up. At this time, the rotating plate limiter 21 is in front of the gravity rotating plate 19. The next pulling force of the angler on the lure is applied to the main line connection point 11, which is below the head of the lure shell 1. When the main line 5 is pulled by the angler, it follows the trajectory defined by the main line traction groove 10 and the direction of force on the main line 5. The main line connection point 11 rotates from directly below the lure to the front, so that the gravity of its own weight causes it to fall. The rotating plate 19 is blocked by the rotating plate limiting clip 21. Because the end of the gravity rotating plate 19, suspended above the rotating gyroscope 2, is located within the serrated edge groove 17, the gravity rotating plate 19 can only push the serrated edge groove 17 to make the gyroscope disc 14 start rotating with the lure. The main line traction groove 10, located above the head of the outer shell 1 from the main line connection point 11 to the tail, restricts the traction trajectory of the main line 5. It is a groove that pulls the lure's head downwards longitudinally through the main line connection point 11. The function of the main line traction groove 10 is that, since the main line traction groove 10 is a groove starting from the main line connection point 11 and extending to the tail of the outer shell 1, when the lure is cast into the water, or when the angler pulls the lure to the head-forward and tail-back position and stops pulling, it returns to its original position. The counterweight 4 is positioned inside the upper part of the outer casing 1, above and forward of the vertical line connecting the two gyroscope shaft holes 7. The weight of the counterweight 4 causes the lure to rotate downwards only from the front, allowing the main line 5 to begin winding around the main line traction groove 10 from the main line connection point 11. Each time the angler quickly lifts the rod, the main line pulls the lure, and the traction force exerted by the main line 5 on the main line connection point 11 (located below the head of the outer casing 1) restricts the trajectory of the main line 5, forcing the lure to rotate downwards only from the head connection point 11. This causes the lure's head to turn from below to front, thus causing the gravity-driven rotating plate 19 suspended above the gyroscope 2 inside the lure casing 1 to rotate the gyroscope 2.The main line connection point 11 is located above the front end of the head of the outer shell 1, connecting to the main line 5. The purpose of placing the main line connection point 11 above the front end of the head of the outer shell 1 is that after the lure is cast into the water, or after the angler pulls the lure until its head is in front and its tail is behind, the weight of the return weight 4 forces the lure to rotate downwards from the front. After rotation, the lure's head is behind, its tail is in front, its back is below, and its belly is above. At this point, the main line connection point 11 is below the front end of the head of the outer shell 1, facilitating the application of a reverse pulling force through the main line 5 to the main line connection point 11, thus causing the lure to rotate downwards.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12As shown, the rotating gyroscope 2 is a gyroscope horizontally arranged in the gyroscope shaft holes 7 on both sides of the outer shell 1. It consists of a gyroscope disk 14 and a gyroscope shaft 15. The gyroscope disk 14 is a disc with a diameter smaller than the inner diameter of the rotating part of the gyroscope disk 14 in the outer shell body 6 minus the length of the rotating plate limit card 21, and a thickness smaller than the width of the inner cavity of the outer shell body 6 where the gyroscope disk 14 is located. It consists of a gyroscope disk body 16, a serrated edge groove 17, and a shaking device 18. The gyroscope disk body 16 is a disc made of a material with a high specific gravity. The function of the gyroscope disk body 16 is to utilize its high specific gravity and the small fulcrum of the gyroscope shaft 15 so that once the gyroscope disk body 16 rotates around the gyroscope shaft 15 as the center, it can rotate under the action of inertia due to its weight. When the gyroscope body 16 stops being driven by external force, it continues to rotate around the gyroscope axis 15 for a period of time. The oblique serrated edge groove 17 is an oblique serrated groove set on the circumferential edge of the gyroscope body 16. The shape of the oblique serrated edge groove 17 is set such that the depth of the force-bearing side of the oblique serrated edge groove 17, that is, the distance from the tangent point of the circumference of the gyroscope body 16 to its center, is greater than the length of the gravity rotation plate body 22 minus the length of the rotation plate limit card 21, and the width is greater than the thickness of the gravity rotation plate 19. The function of the oblique serrated edge groove 17 is, firstly, when the lure is thrown into the water, or when the angler pulls the lure to the head front and the tail back and stops pulling, under the action of the gravity of the return weight 4, the lure will move from the front to the bottom. After reversing, the lure's position is with its head at the back, tail at the front, back at the bottom, and belly at the top. At this point, the gravity-rotating plate 19 is suspended by its own weight within the serrated edge groove 17 above the main body 16 of the gyroscope plate, inside the outer shell 6. When the angler quickly pulls the rod, causing the main line to move rapidly, the traction force applied by the main line 5 to the lure's main line connection point 11 causes the lure's head to rotate from below to in front. This causes the gravity-rotating plate 19 to exert a pushing force on the serrated edge groove 17, causing the gyroscope 2 to begin rotating. Secondly, when the angler stops pulling, the lure stops moving forward. At this point, the lure reverses and returns to its original position via its return weight 4, and the gravity-rotating plate 19 returns to the position it was in before the angler pulled the lure. The gyroscope 2 is suspended above the serrated edge slot 17. Due to its inertia, the gyroscope 2 continues to rotate. Since the direction of rotation of the gyroscope 2 is opposite to the direction of the gravity rotation plate 19 (where no rotation plate limiter 21 is installed), the edge of the serrated edge slot 17 continuously impacts the gravity rotation plate 19 suspended above it during rotation, producing a slight impact sound to attract the attention of the target fish. The shaking device 18 is located on one side of the gyroscope disk body 16, acting as a very small counterweight to disrupt the rotational balance of the gyroscope disk body 16 around the gyroscope axis 15. The function of the shaking device 18 is to prevent the gyroscope 2 from rotating when driven to rotate, as its weight is very small.The slight disruption to the balance of the gyroscope body 16 around the gyroscope axis 15 causes a slight instability in the rotation of the gyroscope 2, but it does not significantly affect the rotation time of the gyroscope 2, causing the entire dummy to vibrate. Furthermore, the rotation of the gyroscope 2 generates sound waves due to friction between the gyroscope axis 15 and the gyroscope axis hole 7, achieving the biomimetic purpose of the dummy still vibrating and emitting friction sound waves even when it stops. The gyroscope axis 15 is a metal shaft with a diameter smaller than the inner diameter of the gyroscope axis hole 7 and a length smaller than the distance between the deepest points of the two gyroscope axis holes 7 located on both sides of the outer shell body 6. The function of the gyroscope axis 15 is to allow the gyroscope body 16 to rotate through the two gyroscope axis holes 7 located on both sides of the outer shell body 6.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12As shown, the gravity switch 3 consists of a gravity rotating plate 19, a rotating plate movable shaft 20, and a rotating plate limiter 21. The gravity rotating plate 19 consists of a gravity rotating plate body 22 and a rotating plate shaft hole 23. The gravity rotating plate body 22 is made of a rigid material, with a length less than the distance from the rotating plate shaft hole 23 to the bottom of the oblique serrated edge groove 17, and greater than the distance from the rotating plate shaft hole 23 to the edge of the oblique serrated edge groove 17. The width is equal to the thickness of the gyroscope body 16, and the thickness is less than the width of the bottom of the oblique serrated edge groove 17. The rotating plate movable shaft 20 is a rotating plate shaft fixed at the gravity switch fixing point 9. Within fixed point 12, a metal shaft with a diameter smaller than the inner diameter of the rotary plate shaft hole 23 is used. The rotary plate limiting clip 21 is a right-angled triangle plate with a height smaller than the distance from the circumferential edge of the oblique sawtooth edge groove 17 to the rotary plate shaft fixing point 12, which is set on the rotary plate limiting clip fixing point 13. Its right-angled side is set on the side adjacent to the gravity rotary plate body 22. The function of the gravity switch 3 is that when the lure is thrown into the water, or when the angler stops pulling the lure to the point where the head is in front and the tail is behind, the lure is reversed under the action of the gravity of the return weight 4. After the lure is reversed, its posture is that the head is behind, the tail is in front, the back is below, and the abdomen is below. At this point, the gravity rotating plate 19 is suspended in the oblique serrated edge slot 17 above the rotating gyroscope 2. When the main line 5 is pulled by the angler along the trajectory defined by the main line pulling groove 10 in the direction of force on the main line 5, and the main line connection point 11 rotates from directly below the lure to the front, the gravity rotating plate 19, which is drooping due to its own weight, is blocked by the rotating plate limiting clip 21. This allows the gravity rotating plate 19 to only push the oblique serrated edge slot 17, causing the gyroscope disc 14 to start rotating with the lure's outer shell 6. When the angler stops this jerk and lifts the rod, the gyroscope disc 14, due to its inertia, continues to rotate, thus driving the rotating gyroscope. The purpose of rotation is that, because the rotating plate limit card 21 is set in the opposite direction to the rotation of the rotating gyroscope 2, the rotation of the rotating gyroscope 2 is not blocked by the gravity rotating plate 19. During the rotation of the rotating gyroscope 2, since the length of the gravity rotating plate 19 is greater than the distance from the fixed point 12 of the rotating plate axis to the circumferential edge of the oblique serrated edge groove 17, the edge of the oblique serrated edge groove 17 hits the gravity rotating plate 19, causing the gravity rotating plate 19 to tilt backward under force. Then, due to its own weight, it droops again, causing the oblique serrated edge groove 17 to continuously hit the gravity rotating plate 19 and emit impact sound waves to attract the attention of the target fish.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 12As shown, the return weight 4 is made of metal and consists of a weight with a specific gravity greater than water and a volume equal to that of the return weight chamber 8. The weight is placed inside the return weight chamber 8. Its function is to cause the lure to flip over when it is cast into the water or when the angler stops pulling the lure with its head in front and its tail behind. After the lure is flipped over, its head is behind, its tail is in front, its back is down, and its belly is up, which prepares the angler for the next jerk and pull.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, main line 5 is a fishing line with a diameter suitable for artificial lures.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, hook 24 is a hook suitable for lure specifications.

[0035] The principle and function of biomimetic lures that continue to swing and make sounds even when no external force is applied:

[0036] I. For example Figure 1 , Figure 2 , Figure 5 As shown, this utility model utilizes the inherent property of the rotating gyroscope 2 to remain in a rotating state before its rotational inertia is exhausted. This allows the rotating gyroscope 2 inside the lure to remain rotating even when the angler stops pulling the rod after each cast, thus eliminating the external force on the lure. This ensures that the lure still exhibits some vital signs of the real lure, such as wriggling, shaking, and emitting impact and friction sound waves.

[0037] II. Figure 1 , Figure 2 , Figure 5 As shown, by utilizing the buoyancy property of water, the dart is designed with a buoyancy structure that reverses immediately after the traction stops, so that the dart exhibits opposite postures when being tractioned and when the traction stops. The traction distance generated by these different body positions is used to drive the rotating gyroscope 2 to rotate.

[0038] III. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 12As shown, by utilizing the principle that gravity causes an object to hang down, the gravity rotation plate 19 of the gravity switch 3 set in the outer shell 1 is configured to be suspended in the oblique sawtooth edge slot 17 on the circumference of the rotating gyroscope 2 when the dummy is in a stopped state. This achieves the purpose of driving the rotating gyroscope 2 to rotate as long as the dummy is pulled, while avoiding the cumbersome process of setting up a separate switch and unnecessary costs.
