[0005] The influencing rotating shell is composed of a shell body, closed air wings, counterweight wings, influencing rotating magnets, counterweights, upper rotating shaft movable cabin, lower rotating shaft movable cabin and driving magnet movable cabin. The shell body is made of hard material, is longitudinally divided into two pieces from the middle of two wings, then the rotating shaft driving device is arranged in one of the two pieces, and then the other piece is bonded to the corresponding piece to form the shell body. The shape is that the upper half of the two sides is provided with closed air wings, the lower half of the two sides is provided with counterweight wings, the middle is a tubular cylinder, the upper half of the tubular cylinder is provided with the upper rotating shaft movable cabin, the lower half of the tubular cylinder is provided with the lower rotating shaft movable cabin, and the middle part of the tubular cylinder is provided with the driving magnet movable cabin. The closed air wing is a wing-shaped wing that encloses air therein. The role of the closed air wing is that first, the buoyancy of the air enclosed therein is used to cooperate with the counterweights in the counterweight wings, so that the bionic casting device capable of simulating the dynamic state of underwater organisms can be kept in an upright posture and suspended in water, and the rotating shaft of the rotating shaft driving device is driven by the wave floating to move longitudinally up and down in the driving magnet movable cabin. Second, due to the equal action and reaction, when the rotating magnet is driven to rotate by the magnetic field induction force of the influencing rotating magnet, the influencing rotating magnet is subjected to the opposite torque at the same time. The closed air wing is arranged on the shell body, and the characteristics of the large surface area and the large water resistance are used to achieve the purpose that when the rotating magnet is driven to rotate by the magnetic field induction force of the influencing rotating magnet, the shell body does not rotate in the opposite direction. The counterweight wing is arranged on the lower half of the shell body to carry the counterweight. The role is that the counterweight cooperates with the buoyancy of the air enclosed in the closed air wing to achieve the state that the bionic casting device capable of simulating the dynamic state of underwater organisms can be kept in an upright and suspended state in water. The influencing rotating magnet is arranged on both sides of the driving magnet movable cabin, and the volume is smaller than that of the rotating magnet in the rotating shaft driving device. When the rotating magnet is driven by the wave floating to move up and down in the driving magnet movable cabin, the influencing rotating magnet uses the magnetic field emitted thereby to make the magnetic poles of the rotating magnet correspond to the magnetic poles of the influencing rotating magnet when the rotating magnet moves up and down through the influencing rotating magnet, so that the rotating magnet generates transverse rotation. When the rotating magnet continues to move up and down, it passes through the influencing rotating magnet arranged on the other side of the driving magnet movable cabin, so that the magnetic poles of the rotating magnet correspond to the magnetic poles of the other influencing rotating magnet, so that the rotating magnet generates transverse rotation again. The rotating magnet drives the rotating shaft in the rotating shaft driving device to continuously rotate transversely, and the subline in the fake bait hook group device fixed to the lower end of the rotating shaft drives the fake bait to rotate synchronously. The counterweight is made of heavy metal lead, and the weight is equal to the buoyancy of the air enclosed in the closed air wing. The role of the counterweight is to cooperate with the buoyancy of the air in the closed air wing to keep the bionic casting device capable of simulating the dynamic state of underwater organisms in an upright and suspended state in water.The upper and lower rotating shaft movable cabins are rotating shaft movable cabins in which the rotating shaft moves up and down, and the lengths of the upper and lower rotating shaft movable cabins are equal to the lengths of the rotating shafts excluding the middle rotating magnets and the weights on both sides of the rotating shafts. The upper and lower rotating shaft movable cabins protect the rotating shafts from being exposed and from being damaged by bending when force is applied. The driving magnet movable cabin is composed of a hollow rotating magnet movable cabin, an upper shaft hole and a lower shaft hole. The inner diameter of the hollow rotating magnet movable cabin is larger than the outer diameter of the rotating magnets, and the height of the hollow rotating magnet movable cabin is larger than the height of the sum of the three rotating magnets and the weight of the rotating shaft. The cabin wall is porous. The hollow rotating magnet movable cabin has the following functions. First, the rotating magnets move up and down in the hollow rotating magnet movable cabin. Second, the porous cabin wall allows water to flow in and out freely when the rotating magnets move up and down, reducing the resistance of the water in the hollow rotating magnet movable cabin to the rotating magnets moving up and down. The upper and lower shaft holes are holes arranged at the centers of the upper and lower ends of the hollow rotating magnet movable cabin, respectively. The diameters of the upper and lower shaft holes are slightly larger than the outer diameter of the rotating shaft and smaller than the outer diameter of the rotating magnets. The upper and lower shaft holes have the following functions. First, the rotating shaft is arranged in the upper and lower shaft holes, and the rotating magnets are arranged between the upper and lower shaft holes, so that the rotating shaft moves in the upper and lower shaft holes. On the one hand, the range of the rotating magnets moving up and down on the rotating shaft is fixed, and on the other hand, the range of the rotating magnets rotating is limited, so that the rotating range of the rotating magnets is not larger than the inner diameter of the hollow rotating magnet movable cabin, avoiding the friction between the rotating magnets and the inner wall of the hollow rotating magnet movable cabin when the rotating magnets rotate, which affects the rotating function of the rotating magnets. Second, the horizontal distance between the rotating magnets and the influencing rotating magnets is controlled. On the one hand, the horizontal distance between the rotating magnets and the influencing rotating magnets is not too close, and the attractive force between them is not too strong, which affects the up-and-down movement of the rotating magnets. On the other hand, the horizontal distance between the rotating magnets and the influencing rotating magnets is not too far, so that the magnetic field of the influencing rotating magnets is too weak to drive the rotating magnets to rotate horizontally due to the long distance, and the function of the influencing rotating magnets is lost.

[0006] The rotating shaft driving device is composed of a wave floating, a main line, a rotating shaft, a rotating magnet, and a rotating shaft counterweight. The wave floating has a buoyancy greater than the sum of the weight of the rotating shaft, the rotating magnet, the rotating shaft counterweight, and the lure hook set device in water.

The rotating magnet is a cylindrical magnet with a middle hole, a strong magnet, an outer diameter smaller than the inner diameter of the driving magnet movable cabin, an inner diameter greater than the diameter of the rotating shaft, an outer diameter greater than the inner diameter of the upper shaft hole and the lower shaft hole, and a height smaller than 1 / 3 of the height of the driving magnet movable cabin. The magnetic field direction of the rotating magnet is radial. The rotating magnet is set in the middle of the rotating shaft through the middle hole. The rotating magnet is used to move up and down with the rotating shaft driven by the wave floating, to move up and down in the driving magnet movable cabin, to correspond to the magnetic field of the influence rotating magnet when the rotating magnet moves to the influence rotating magnet at different heights on both sides of the driving magnet movable cabin, to drive the rotating magnet to rotate, to correspond to the magnetic field of the influence rotating magnet on the other side when the rotating magnet moves to the influence rotating magnet on the other side of the driving magnet movable cabin, to drive the rotating magnet to rotate to the other side, to drive the rotating magnet to rotate, and to drive the sub-line to rotate and swing continuously with the fish hook and the lure.The rotating shaft counterweight is made of heavy metal lead, and has an outer diameter equal to that of the rotating magnet, an outer diameter greater than the inner diameters of the upper shaft hole and the lower shaft hole, and an inner diameter equal to that of the rotating magnet, and is arranged at two ends of the rotating magnet through the rotating shaft.

[0018] As shown in Figure 1 , Figure 2 The utility model discloses a bionic casting aid device which can imitate the dynamic of underwater creature, which is composed of a rotating shell, a rotating shaft driving device and a lure hook group device. The rotating shaft driving device drives a wave float 15 on the water surface by surge, and the wave float 15 pulls a rotating magnet 18 in the middle of a rotating shaft 17 through a main line 16, which moves up and down in a driving magnet movable cabin 11 of the rotating shell. The rotating magnet 18 is affected by the magnetic field of an affecting rotating magnet 7 on both sides of the driving magnet movable cabin 11, and rotates continuously, which drives the rotating shaft 17 to rotate continuously, and drives the sub line 28 fixed at the lower end of the rotating shaft 17 to drive the lure 26 of the lure hook group device 3 to rotate and swing continuously, so as to achieve the purpose of dynamic imitation of the lure 26 without battery driving.

[0019] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the impact rotating shell 1 is composed of shell body 4, closed air wing 5, counterweight wing 6, impact rotating magnet 7, counterweight 8, upper rotating shaft movable cabin 9, lower rotating shaft movable cabin 10 and drive magnet movable cabin 11. The shell body 4 is made of hard material, which is longitudinally divided into two pieces from the middle of the two wings, then the rotating shaft drive device 2 is set in one of the two pieces, and then the other piece is bonded to the corresponding piece to form the shell body 4. Its shape is that the upper half of the two sides is provided with closed air wing 5, the lower half of the two sides is provided with counterweight wing 6, and the middle is a tubular cylinder. The upper half of the tubular cylinder is provided with the upper rotating shaft movable cabin 9, the lower half of the tubular cylinder is provided with the lower rotating shaft movable cabin 10, and the middle part of the tubular cylinder is provided with the drive magnet movable cabin 11. The closed air wing 5 is a wing-shaped wing that encloses air in it. The role of the closed air wing 5 is that first, by using the buoyancy of the air enclosed by it, cooperating with the counterweight 8 in the counterweight wing 6, the bionic assisting device that can imitate the dynamic of underwater organisms can keep a straight-up posture suspended in water, so that the rotating shaft 17 of the rotating shaft drive device 2 is driven by the wave floating buoy 15 to move longitudinally up and down in the drive magnet movable cabin 11, second, due to the equal action and reaction, when the rotating magnet 18 is driven to rotate by the magnetic field induction force of the impact rotating magnet 7, the impact rotating magnet 7 is simultaneously subjected to the opposite torque. By setting the closed air wing 5 on the shell body 1, using its large surface area and large water resistance, when the rotating magnet 18 is driven to rotate by the magnetic field induction force of the impact rotating magnet 7, the shell body 1 does not rotate in the opposite direction. The purpose of the counterweight wing 6 is to carry the counterweight 8 on the lower half of the shell body 4, which cooperates with the buoyancy of the air enclosed in the closed air wing 5 to achieve the state of the bionic assisting device that can imitate the dynamic of underwater organisms in water. The impact rotating magnet 7 is set on both sides of the drive magnet movable cabin 11, which is smaller than the rotating magnet 18 in the rotating shaft drive device 2. When the rotating magnet 18 is moved up and down in the drive magnet movable cabin 11 by the wave floating buoy 15 through the rotating shaft 17, the impact rotating magnet 7 uses its magnetic field to make the magnetic pole of the rotating magnet 18 correspond to the magnetic pole of the impact rotating magnet 7 when the rotating magnet 18 moves up and down through the impact rotating magnet 7, so that the rotating magnet 18 generates transverse rotation. When the rotating magnet 18 continues to move up and down, it passes through the impact rotating magnet 7 set on the other side of the drive magnet movable cabin 11, so that the magnetic pole of the rotating magnet 18 corresponds to the magnetic pole of the other impact rotating magnet 7, thereby making the rotating magnet 18 generate transverse rotation again. The rotating magnet 18 drives the rotating shaft 17 in the rotating shaft drive device 2 to continuously rotate transversely, and the subline 28 in the fake bait hook group device 3 fixed to the lower end of the rotating shaft 17 drives the fake bait 26 to rotate synchronously.The counterweight 8 is made of heavy metal lead, and its weight is equal to the buoyancy of the enclosed air in the enclosed air side wing 5 to the outer shell body 4. The role of the counterweight 8 is to cooperate with the buoyancy of the air in the enclosed air side wing 5, so that the bionic assist throwing device which can simulate the dynamic of underwater organisms can keep upright and suspended in water. The upper rotating shaft movable cabin 9 and the lower rotating shaft movable cabin 10 are rotating shaft movable cabins for the up-and-down movement of the rotating shaft 17. The length of the upper rotating shaft movable cabin 9 and the lower rotating shaft movable cabin 10 is equal to the length of the rotating shaft 17 excluding the middle rotating magnet 18 and the rotating shaft counterweight 19 on both sides. The role of the upper rotating shaft movable cabin 9 and the lower rotating shaft movable cabin 10 is to protect the rotating shaft 17 from being exposed and to avoid the bending of the rotating shaft 17 after being stressed, which can damage its mechanical properties. The driving magnet movable cabin 11 is composed of a hollow rotating magnet movable cabin 12, an upper shaft hole 13 and a lower shaft hole 14. The inner diameter of the hollow rotating magnet movable cabin 12 is greater than the outer diameter of the rotating magnet 18, and the height is greater than the height of the sum of the three rotating magnets 18 and the rotating shaft counterweight 19. The cabin wall is porous. The role of the hollow rotating magnet movable cabin 12 is that, first, the rotating magnet 18 moves up and down in it, and second, the porous cabin wall allows the water pushed by the rotating magnet 18 to flow in and out freely, reducing the resistance of the water in the hollow rotating magnet movable cabin 12 to the up-and-down movement of the rotating magnet 18. The upper shaft hole 13 and the lower shaft hole 14 are holes respectively arranged at the center of the upper end and the lower end of the hollow rotating magnet movable cabin 12. The diameter is slightly larger than the outer diameter of the rotating shaft 17 and smaller than the outer diameter of the rotating magnet 18. The role of the upper shaft hole 13 and the lower shaft hole 14 is to set the rotating shaft 17 in the upper shaft hole 13 and the lower shaft hole 14, so that the rotating magnet 18 is arranged between the upper shaft hole 13 and the lower shaft hole 14, and the rotating shaft 17 moves in the upper shaft hole 13 and the lower shaft hole 14. On the one hand, it fixes the range of the up-and-down movement of the rotating magnet 18 arranged on the rotating shaft 17, and on the other hand, it limits the range of the rotation of the rotating magnet 18, so that the rotation range of the rotating magnet 18 is not greater than the inner diameter of the hollow rotating magnet movable cabin 12, avoiding the friction between the rotating magnet 18 and the inner wall of the hollow rotating magnet movable cabin 12 when rotating, which affects the rotation function of the rotating magnet 18. Third, the lateral distance between the rotating magnet 18 and the affecting rotating magnet 7 is controlled. On the one hand, it avoids the lateral distance between the rotating magnet 18 and the affecting rotating magnet 7 being too close, and the attractive force between them being too strong, which affects the up-and-down movement of the rotating magnet 18. On the other hand, it avoids the lateral distance between the rotating magnet 18 and the affecting rotating magnet 7 being too far, so that the magnetic field of the affecting rotating magnet 7 is too weak due to the too far distance to drive the lateral rotation of the rotating magnet 18 and loses its function.

[0020] As Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, the rotating shaft driving device 2 is composed of a wave float 15, a main line 16, a rotating shaft 17, a rotating magnet 18, and a rotating shaft counterweight 19. The wave float 15 is a float with a buoyancy greater than the sum of the weight of the rotating shaft 17, the rotating magnet 18, the rotating shaft counterweight 19, and the fake bait hook set device 3 in water. The wave float 15 is connected through the upper traction point 23 connecting the main line 16 and the rotating shaft 17. The function of the wave float 15 is to use the characteristics of the wave float 15 rising and falling with the waves to drive the rotating shaft 17, the rotating magnet 18, the rotating shaft counterweight 19, and the fish hook and fake bait in the fake bait hook set device 3 to move up and down through the main line 16. The main line 16 is a fishing line connecting the wave float 15 and the rotating shaft 17, and its length is determined by the depth set by the bionic casting device that can simulate the dynamic of underwater organisms. The rotating shaft 17 is composed of a rotating shaft body 20, a rotating magnet fixing point 21, a rotating shaft counterweight fixing point 22, an upper traction point 23, and a lower traction point 24. The rotating shaft body 20 is a cylindrical shaft made of a straight metal strip with a diameter smaller than the inner diameter of the upper shaft hole 13 and the lower shaft hole 14 and stronger elasticity. The rotating magnet fixing point 21 is a point set in the middle of the rotating shaft body 20 to fix the rotating magnet 18. The rotating shaft counterweight fixing point 22 is a point set in the middle of the rotating shaft body 20 to fix the rotating shaft counterweight 19 at the upper and lower ends of the rotating magnet 18. The upper traction point 23 is set at the upper end of the rotating shaft body 20 and is the connection point of the rotating shaft 17 and the main line 16. The lower traction point 24 is set at the lower end of the rotating shaft body 20 and is the connection point of the rotating shaft 17 and the sub-line 28. The function of the rotating shaft 17 is that first, the rotating shaft 17 moves up and down through the main line 16 driven by the wave float 15 rising and falling with the waves, which makes the rotating magnet 18 set on the rotating shaft 17 move up and down with the rotating shaft 17. Second, the rotating range and the up-and-down movement interval of the rotating shaft 17 are limited by the upper shaft hole 13 and the lower shaft hole 14, which makes the rotating magnet 18 fixed in the middle of the rotating shaft 17 rotate and move according to the set rotating range and movement interval. Third, the sub-line 28 connected by the lower traction point 24 at the lower end of the rotating shaft 17 drives the fake bait 26 to rotate and swing. The rotating magnet 18 is a cylindrical magnet with a middle hole 25, which is made of strong magnet with an outer diameter smaller than the inner diameter of the driving magnet movable cabin 11, an inner diameter larger than the diameter of the rotating shaft 17, an outer diameter larger than the inner diameter of the upper shaft hole 13 and the lower shaft hole 14, and a height smaller than 1 / 3 of the height of the driving magnet movable cabin 11. The magnetic field direction is radial. The rotating magnet 18 is set in the middle of the rotating shaft 17 through the middle hole 25. The function of the rotating magnet 18 is that the rotating magnet 18 moves up and down in the driving magnet movable cabin 11 driven by the rotating shaft 17, which makes the rotating magnet 18 move up and down in the driving magnet movable cabin 11 when it moves to the vicinity of the influence rotating magnet 7 set at different heights on both sides of the driving magnet movable cabin 11.The driving rotating magnet 18 drives the rotating shaft 17 to rotate. When the driving rotating magnet 18 moves up and down, it moves to the influencing rotating magnet 7 arranged on the other side of the driving magnet movable cabin 11, and under the action of the magnetic field attraction of the influencing rotating magnet 7, the magnetic field of the driving rotating magnet 18 corresponds to the magnetic field of the influencing rotating magnet 7 on the other side, so that the driving rotating magnet 18 drives the rotating shaft 17 to turn to the other side, and the rotating shaft 17, the fishhook 27 and the lure 26 fixed to the lower end of the rotating shaft 17 are driven to rotate and swing continuously, so as to achieve the purpose of driving the lure 26 to dynamically imitate. The rotating shaft counterweight 19 is made of metal lead with a larger specific gravity, and has an outer diameter equal to that of the rotating magnet 18, an outer diameter larger than the inner diameter of the upper shaft hole 13 and the lower shaft hole 14, and an inner diameter equal to that of the rotating magnet 18. The rotating shaft counterweight 19 is arranged at both ends of the rotating magnet 18 through the rotating shaft 17. The rotating shaft counterweight 19 has the following effects: first, the bionic casting aid device capable of imitating the dynamic behavior of underwater organisms can reach a certain weight, which can carry the lure 26 with lighter self-weight to a farther distance; second, the rotating shaft counterweight 19 is arranged at both ends of the rotating magnet 18, so that the rotating shaft 17 is heavier, and when the wave moving float 15 drives the rotating shaft 17 to complete the upward movement, the weight of the rotating shaft counterweight 19 rapidly pulls the rotating shaft 17 downward with the wave, so that the rotating magnet 18 arranged in the middle of the rotating shaft 17 moves up and down continuously.
