Description

Technical Field

[0001] This utility model relates to the field of fishing technology, and in particular to a biomimetic artificial lure that can swing up and down. Background Technology

[0002] The current drawbacks of lures used by lure enthusiasts are: first, during lure fishing, lures can only exhibit a left-right swaying motion, not a vertical swaying motion, resulting in a monotonous performance in actual fishing; second, when searching the surface, they can only float on the surface and cannot simulate the escape effect of the lure frequently leaping out of the water. To address these shortcomings, a method is used that involves setting one traction point on each side of the front of the lure's body to simultaneously pull it, thereby controlling the lure's swaying motion as it moves through the water. This allows the lure to exhibit only a vertical swaying swimming motion, similar to that of a flounder, while also enabling surface-type lures to frequently leap out of the water when pulled quickly, simulating an escape action. Summary of the Invention

[0003] The purpose of this invention is to provide a biomimetic artificial lure that can swing up and down. It is characterized by comprising a first section, a traction shaft, a U-shaped swivel, a main line, a transverse shaft, a second section, a third section, a tail section, a spring hammer, a counterweight, and a hook. The traction shaft is horizontally positioned within the transverse traction shaft hole at the front of the first section. The U-shaped swivel is connected to the end holes at both ends of the traction shaft via U-shaped end connecting rings at both ends of the U-shape. The main line is connected to the U-shaped middle connecting ring of the U-shaped swivel. The spring hammer is horizontally positioned within the second section via a spring wire. Each section is sequentially connected to the transverse shaft and the front and rear transverse shaft holes of each section. When the angler casts the lure into the water and retrieves the line, the traction force of the main line on the lure is applied to the traction shaft horizontally positioned at the front of the lure. Since the main line simultaneously pulls both ends of the traction shaft via the U-shaped swivel, and the lure is entirely connected via the transverse shaft, the lure can only exhibit a swinging swimming motion when moving forward, due to the resistance from the water, similar to the swimming motion of a flounder.

[0004] The first section consists of a first-section outer shell, a rectifier end, a transverse traction shaft bore, a buoyancy chamber, a counterweight chamber, and the first-section transverse shaft bore. The first-section outer shell is made of rigid material and resembles the head of the target lure. The rectifier end, also made of rigid material, is a rectifier plate located at the front of the first-section outer shell. Its function is to rectify the water flowing towards the lure upwards or downwards. The angle is set according to the target water layer, and it acts as a rectifier surface to make the lure float or submerge as it moves through the water. The transverse traction shaft bore is located transversely at the rear of the rectifier end and is the shaft bore for the traction shaft. Its inner diameter is larger than the diameter of the traction shaft, and its length is smaller than the two flattened ends of the traction shaft. The distance between them serves to allow the traction shaft to be inserted into the transverse traction shaft hole, and the two end holes at both ends of the traction shaft to be connected through the U-shaped end connecting ring of the U-shaped swivel. After connecting the main line to the U-shaped middle connecting ring of the U-shaped swivel, the counterweight and hook are set in the corresponding positions in each section. The first, second, third, and last sections are connected sequentially through the transverse shaft and the front and rear transverse shaft holes of each section. When the angler casts the lure into the water and retrieves the line, the traction force of the main line on the lure is applied to the traction shaft transversely set at the front end of the lure. Furthermore, because the main line simultaneously pulls both ends of the traction shaft through the U-shaped swivel, and because... The counterweights located at the bottom of each segment and the buoyancy chambers located at the top of each segment ensure that the lure maintains a belly-down, back-up posture in the water. This allows the first segment to only move up and down via the lateral traction shaft hole when propelled forward, mimicking the characteristic up-and-down swimming motion of some fish, such as flounder. The buoyancy chambers, enclosed air chambers located in the upper part of the first segment's outer shell, provide buoyancy to the lure in conjunction with the counterweights, allowing the lure to... The lure maintains a belly-down, back-up posture in the water. The counterweight chamber is located in the lower half of the first section of the outer shell, where counterweights are placed. Its function is to work with the buoyancy of the buoyancy chamber to keep the lure in a belly-down, back-up posture in the water. The first section transverse shaft hole is a hole transversely located at the rear end of the first section of the outer shell. Its inner diameter is equal to the inner diameter of the transverse shaft holes of the second section front, second section rear, third section front, third section rear, and tail section front, and is larger than the diameter of the transverse shaft. It is a connecting hole that connects the first and second sections of the lure by placing the transverse shaft in the transverse shaft hole of the first section and the transverse shaft hole of the second section front.

[0005] The traction shaft is made of cylindrical metal, consisting of a traction shaft body, flattened ends, and end holes. The traction shaft body is a cylindrical metal with a length greater than the length of the transverse traction shaft hole and a diameter smaller than the inner diameter of the transverse traction shaft hole. The flattened ends are plate-shaped pieces formed by stamping the traction shaft body and are located at both ends of the traction shaft body. The flattened ends act as limiters to prevent the traction shaft from disengaging from the transverse traction shaft hole, allowing the first section to swing up and down around the traction shaft through the transverse traction shaft hole. The end holes are holes located at the flattened ends and connect the connecting rings at both ends of the U-shaped swivel. The traction shaft passes through the transverse traction shaft hole, connecting the connecting rings at both ends of the U-shaped swivel to the two end holes. When the main line pulls the two end hole traction points forward simultaneously through the U-shaped swivel, the resistance of the oncoming water forces the first section to only be able to swing up and down around the traction shaft through the transverse traction shaft hole.

[0006] A U-shaped swivel is a three-pronged swivel with two adjacent sides shaped into a U-shape. It consists of a U-shaped swivel body, U-shaped end connecting rings, and a U-shaped middle connecting ring. The U-shaped swivel body is formed by two connecting sides of the three-pronged swivel forming a U-shape. The U-shaped end connecting rings are the connecting rings at both ends of the U-shape of the swivel. The U-shaped middle connecting ring is the connecting ring at the end of the straight side in the middle of the U-shape, in addition to the two sides of the U-shape. The function of the U-shaped swivel is to connect the two end holes of the traction shaft through the U-shaped end connecting rings at both ends of the U-shape, and then connect the main line to the U-shaped middle connecting ring of the U-shaped swivel. This forms the main line, which simultaneously pulls the end holes at both ends of the traction shaft. The U-shaped swivel also prevents the rectifier end of the first section from scraping against the U-shaped swivel when it swings up and down. The main line is the fishing line that connects to the lure.

[0007] The transverse shaft is made of cylindrical metal and has a diameter smaller than the inner diameter of the transverse shaft hole of the first section. Its function is to connect the sections of the lure by passing through the transverse shaft holes of each section in sequence, and to allow each section to swing up and down around the transverse shaft through the transverse shaft holes of each section.

[0008] The second section consists of a second-section outer shell, a spring hammer and wire fixing point, a front transverse shaft hole, a rear transverse shaft hole, and a back hook connection point. The second-section outer shell is the rear section of the target lure's body, made of a hard material. The spring hammer and wire fixing point is located at the center of the front end of the second-section outer shell, connecting the spring wire to the spring hammer. The purpose of placing the spring hammer and wire fixing point at the center of the front end of the second-section outer shell is to ensure that the highly elastic spring wire, with a diameter and strength just sufficient to support the spring wire parallel to the hammer head within the second-section's inner chamber, allows for precise control of the second section's movement. When making up-and-down undulating movements, the elastic wire causes the hammer head to swing up and down in the inner chamber of the second section. The elasticity of the elastic wire causes the hammer head to repeatedly strike the upper and lower chamber walls of the inner cavity of the second section, producing a sound to attract the attention of the target fish. The front transverse shaft hole of the second section is a connecting hole located at the front end of the second section, which connects to the first transverse shaft hole of the first section through the transverse shaft. The rear transverse shaft hole of the second section is a connecting hole located at the rear end of the second section, which connects to the third transverse shaft hole of the third section through the transverse shaft. The back hook connection point is a connection point located on the back of the second section shell to connect the fish hook.

[0009] The three-section design consists of a three-section outer shell, a three-section buoyancy chamber, a three-section counterweight chamber, a three-section front transverse shaft hole, and a three-section rear transverse shaft hole. The three-section outer shell is the rear section of the target lure's body, made of rigid material. The three-section buoyancy chamber is an airtight compartment located in the upper half of the three sections. Its function is to provide buoyancy for the lure, which, together with the counterweight, keeps the lure in a belly-down, back-up position in the water. The three-section counterweight chamber is a compartment located in the lower half of the three sections, where the counterweight is placed. Its function is to work with the buoyancy of the three-section buoyancy chamber to keep the lure in a position... In the water, the belly is below and the back is above. The transverse shaft hole at the front of the third segment is a hole set transversely at the front end of the third segment. Its inner diameter is larger than the diameter of the transverse shaft. It is a connecting hole that connects the second and third segments of the lure by placing the transverse shaft in the transverse shaft hole behind the second segment and the transverse shaft hole at the front of the third segment. The transverse shaft hole at the rear of the third segment is a hole set transversely at the rear end of the third segment. Its inner diameter is larger than the diameter of the transverse shaft. It is a connecting hole that connects the third and third segments of the lure by placing the transverse shaft in the transverse shaft hole behind the third segment and the transverse shaft hole at the front of the tail segment.

[0010] The tail section consists of a tail section shell, a front transverse shaft hole, a tail section buoyancy chamber, a tail section counterweight chamber, and a tail hook connection point. The tail section shell is the shape of the target lure's tail made of a hard material. The front transverse shaft hole is a hole set horizontally at the front end of the tail section, and its inner diameter is larger than the diameter of the transverse shaft. It is a connecting hole that connects the three sections of the lure to the tail section by setting the transverse shaft hole in the rear transverse shaft hole of the third section and the front transverse shaft hole of the tail section. The tail hook connection point is located at the tail of the tail section and is the connection point for connecting the fish hook.

[0011] The elastic hammer consists of a spring wire and a hammer head. The spring wire is a highly elastic metal wire, such as nickel-titanium alloy or high-carbon steel. Its length is set to be less than the combined length of the spring wire and the hammer head, which is also less than the horizontal distance between the front and back of the secondary outer shell. Its diameter is set to be such that, when combined with the hammer head, it is horizontally positioned inside the secondary outer shell. The strength of the spring wire is such that it can barely lift the hammer head off the bottom of the secondary outer shell. The hammer head is a sphere made of a hard material, and its diameter is less than the minimum spacing between the inner chambers of the secondary outer shell. Its weight is set to be such that, when combined with the spring wire, it is horizontally positioned inside the secondary outer shell. The strength of the spring wire is such that it can barely lift the hammer head off the bottom of the secondary outer shell. The function of the elastic hammer is to prevent the lure from moving forward in the water when the angler pulls it. Due to the resistance of the water, the lure is pulled along the traction shaft... The U-shaped swivel, the transverse shaft, and the transverse shaft holes in each section restrict the direction of the lure's swing, causing the lure to exhibit an up-and-down swaying swimming motion as it moves forward. Because the elastic wire of the spring hammer horizontally set inside the secondary shell is only strong enough to barely lift the hammer head off the bottom of the secondary shell, and because the elastic wire is extremely elastic, when the lure swings up and down continuously as it moves forward, the rhythm of the elastic wire driving the hammer head to swing up and down is half a beat slower than the rhythm of the secondary shell's up-and-down swaying. Therefore, the hammer head, which is set halfway up inside the secondary shell through the elastic wire, is deviated from the rhythm of the secondary shell's up-and-down swaying under the elastic force of the elastic wire, causing the elastic wire to drive the hammer head to continuously hit the upper and lower walls of the secondary shell, making a sound to attract the attention of the target fish.

[0012] The counterweight is an object with a volume equal to that of the counterweight chamber and a specific gravity greater than water, placed inside the counterweight chamber. Its function is to work with the buoyancy of the buoyancy chamber to keep the lure in a position with its belly down and its back up in the water. The fishhook is a fishhook whose size is suitable for the body of the lure.

[0013] This invention relates to a biomimetic artificial lure that can swing up and down. It utilizes the principle of simultaneously pulling the lure laterally from both ends of a traction shaft, fixing the lure in place to swing up and down due to water resistance. This mimics the principle that a flag's swaying motion in the wind depends on the direction of the flagpole; if the flagpole is upright, the flag will swing left and right; if the flagpole is horizontal, the flag will swing up and down. Furthermore, it utilizes the buoyancy of a buoyancy chamber located in the upper part of the fish's body, combined with the gravity of a counterweight located in the lower part, to maintain the fish's posture, thus mimicking the up-and-down swimming motions of target fish. This invention also utilizes the slow-transmission characteristic of elastic wires to passively applied forces, setting the strength of the elastic wires to... When combined with the hammer, the wire is horizontally positioned inside the secondary shell. The strength of the elastic wire is barely enough to lift the hammer off the bottom of the secondary shell. Because the elastic wire is extremely elastic, when the lure moves forward and swings up and down, the transmission of the force from the elastic wire to the hammer after being subjected to the up-and-down swing of the secondary shell is delayed. This causes the rhythm of the elastic wire driving the hammer to swing up and down with the secondary shell to be half a beat slower than the rhythm of the secondary shell's up-and-down swing. Therefore, the hammer, which is horizontally positioned in the middle of the secondary shell's inner compartment by the elastic wire, is deviated from the rhythm of the secondary shell's up-and-down swing under the elastic force of the wire. This causes the elastic wire to drive the hammer to continuously hit the upper and lower walls of the secondary shell, making a sound to attract the attention of the target fish.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention is implemented as follows: it is characterized by comprising a first section 1, a traction shaft 2, a U-shaped swivel 3, a main line 4, a transverse shaft 5, a second section 6, a third section 7, a tail section 8, a spring hammer 9, a counterweight 10, and a fishhook 11. The traction shaft 2 is horizontally positioned in the transverse traction shaft hole 14 at the front of the first section 1. The U-shaped swivel 3 is connected to the end holes 20 at both ends of the traction shaft 2 via U-shaped end connecting rings 22 at both ends of the U-shape. The main line 4 is connected to the U-shaped middle connecting ring 23 of the U-shaped swivel 3. The spring hammer 9 is... Hammer 9 is horizontally set inside the secondary section 6 via spring wire 39. Each section is connected sequentially via transverse shaft 5 and the front and rear transverse shaft holes of each section. When the angler casts the lure into the water and retrieves the line, the traction force of the main line 4 on the lure is applied to the traction shaft 2 set horizontally at the front of the lure. Since the main line 4 pulls both ends of the traction shaft 2 simultaneously through the U-shaped swivel 3, and all the lures are connected by transverse shaft 5, the lure can only exhibit a swimming posture of up and down swinging under the action of the oncoming resistance from the water when moving forward.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the first section 1 consists of a first section outer shell 12, a rectifier end 13, a transverse traction shaft hole 14, a buoyancy chamber 15, a counterweight chamber 16, and a first section transverse shaft hole 17. The first section outer shell 12 is the head shape of the target lure made of rigid material. The rectifier end 13 is also made of rigid material and is a rectifier plate located at the front end of the first section outer shell 12. Its function is to rectify the water flowing towards the lure upwards or downwards. It is tilted according to the target water layer and is a rectifier surface that makes the lure float or submerge when moving forward in the water. The transverse traction shaft hole 14 is located transversely at the rear of the rectifier end 13 and is the shaft hole for the traction shaft 2. Its inner diameter is larger than the diameter of the traction shaft 2, and its length is smaller than two times the length of the traction shaft 2. The distance between the flattened ends 19 serves to allow the traction shaft 2 to pass through the transverse traction shaft hole 14 and connect the two end holes 20 at both ends of the traction shaft 2 via the U-shaped end connecting ring 22 of the U-shaped swivel 3. After connecting the main line 4 to the U-shaped middle connecting ring 23 of the U-shaped swivel 3, the counterweight 10 and the hook 11 are respectively placed in the corresponding positions in each section. The first section 1, the second section 6, the third section 7, and the tail section 8 are connected sequentially through the transverse shaft 5 and the front and rear transverse shaft holes of each section. When the angler casts the lure into the water and retrieves the line, the traction force of the main line 4 on the lure is applied to the traction shaft 2 transversely located at the front end of the lure. Also, because the main line 4 pulls both ends of the traction shaft 2 simultaneously through the U-shaped swivel 3... Furthermore, due to the counterweights 10 located at the bottom of each segment and the buoyancy chambers 15 located at the top of each segment, the lure maintains a posture with its belly down and back up in the water. This allows the first segment 1 to only move forward under the influence of the water's resistance, resulting in it swinging up and down around the traction shaft 2 via the transverse traction shaft hole 14. Similarly, the second segment 6, third segment 7, and tail segment 8 swing up and down around the transverse shaft 5 of each segment via the front and rear transverse shaft holes, mimicking the unique up-and-down swimming posture of some fish, such as flounder. The buoyancy chamber 15 is an airtight chamber located in the upper half of the first segment's outer shell 12. Its function is to provide buoyancy for the lure, working in conjunction with the counterweights 10 to make the lure... To maintain the lure's belly-down, back-up posture in the water, the counterweight chamber 16 is a chamber located in the lower half of the first section shell 12 where the counterweight 10 is placed. Its function is to cooperate with the buoyancy of the buoyancy chamber 15 to keep the lure in the water with its belly-down, back-up posture. The first section transverse shaft hole 17 is a hole transversely located at the rear end of the first section shell 12. Its inner diameter is equal to the inner diameter of the second section front transverse shaft hole 26, the second section rear transverse shaft hole 27, the third section front transverse shaft hole 32, the third section rear transverse shaft hole 33, and the tail section front transverse shaft hole 35, and is greater than the diameter of the transverse shaft 5. The transverse shaft 5 is set in the first section transverse shaft hole 17 and the second section front transverse shaft hole of the second section 6, which is the connecting hole for connecting the first section 1 and the second section 6 of the lure.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the traction shaft 2 is made of cylindrical metal, consisting of a traction shaft body 18, flattened ends 19, and end holes 20. The traction shaft body 18 is a cylindrical metal with a length greater than the length of the transverse traction shaft hole 14 and a diameter smaller than the inner diameter of the transverse traction shaft hole 14. The flattened ends 19 are plate-shaped pieces formed by stamping the traction shaft body 18 and are located at both ends of the traction shaft body 18. The function of the flattened ends 19 is to act as a limiter to prevent the traction shaft 2 from disengaging from the transverse traction shaft hole 14, allowing the first section 1 to pass through the transverse traction shaft hole 14. 4. Swings up and down around the traction shaft 2. The end hole 20 is a hole set in the flattened end 19. The function of the end hole 20 is to connect the U-shaped end connecting ring 22 of the U-shaped rotating ring 3. The function of the traction shaft 2 is to pass through the transverse traction shaft shaft hole 14 so that the connecting rings at both ends of the U-shaped rotating ring 3 connect the two end holes 20. When the main line 4 is pulled forward by the two end holes 20 simultaneously through the U-shaped rotating ring 3, under the resistance of the oncoming water, the first section 1 is forced to only generate a swimming posture of swinging up and down around the traction shaft 2 through the transverse traction shaft shaft hole 14.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the U-shaped swivel 3 is a three-pronged swivel with two adjacent sides of a suitable-sized three-pronged swivel set in a U-shape. It consists of a U-shaped swivel body 21, a U-shaped end connecting ring 22, and a U-shaped middle connecting ring 23. The U-shaped swivel body 21 is formed by two connecting sides of the three-pronged swivel into a U-shape. The U-shaped end connecting ring 22 is a connecting swivel set at both ends of the U-shape of the three-pronged swivel. The U-shaped middle connecting ring 23 is a connecting swivel set at the end of the straight side in the middle of the U-shape, in addition to the two sides of the U-shape. The function of the U-shaped swivel 3 is to connect the two end holes 20 of the traction shaft 2 through the U-shaped end connecting rings 22 at both ends of the U-shape, and then connect the main line 4 to the U-shaped middle connecting ring 23 of the U-shaped swivel 3, so that the main line 4 can simultaneously pull the end holes 20 at both ends of the traction shaft 2. At the same time, setting the U-shaped swivel 3 into a U-shape prevents the rectifier end 13 of the first section 1 from scraping against the U-shaped swivel 3 when it swings up and down. The main line 4 is the fishing line that connects the lure.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 9 As shown, the transverse shaft 5 is made of cylindrical metal and has a diameter smaller than the inner diameter of the transverse shaft hole 17 of the first section. Its function is to connect the sections of the dart by passing through the transverse shaft holes of each section in sequence, and to make each section swing up and down around the transverse shaft 5 through the transverse shaft holes of each section.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 11 As shown, the second section 6 consists of a second section outer shell 24, a spring hammer wire fixing point 25, a front transverse shaft hole 26, a rear transverse shaft hole 27, and a back hook connection point 28. The second section outer shell 24 is the shape of the rear part of the target lure's head, made of hard material. The spring hammer wire fixing point 25 is located at the center of the front end of the inner cavity of the second section outer shell 24, connecting the spring wire 39 of the spring hammer 9. The purpose of setting the spring hammer wire fixing point 25 at the center of the front end of the inner cavity of the second section outer shell 24 is to ensure that the spring wire 39, which is parallel to the hammer head 40 and arranged in parallel with the inner cavity of the second section 6, can be used to support the highly elastic spring wire 39 with a diameter that is just strong enough to support the spring wire 39. When the 6 section makes an up-and-down undulating motion, the elastic wire 39 drives the hammer head 40 to swing up and down in the inner chamber of the second section 6. The elasticity of the elastic wire 39 causes the hammer head 40 to repeatedly strike the upper and lower chamber walls of the inner cavity of the second section shell 24, making a sound to attract the attention of the target fish. The front transverse shaft hole 26 of the second section is set at the front end of the second section 6 and is a connecting hole that connects to the first section transverse shaft hole 17 of the first section 1 through the transverse shaft 5. The rear transverse shaft hole 27 of the second section is set at the rear end of the second section 6 and is a connecting hole that connects to the third section front transverse shaft hole 32 of the third section 7 through the transverse shaft 5. The back hook connection point 28 is a connection point that connects to the fish hook 11 on the back of the second section shell 24.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 9 As shown, the three-section 7 consists of a three-section outer shell 29, a three-section buoyancy chamber 30, a three-section counterweight chamber 31, a three-section front transverse shaft hole 32, and a three-section rear transverse shaft hole 33. The three-section outer shell 29 is the body shape of the rear section 6 of the target lure, made of rigid material. The three-section buoyancy chamber 30 is an airtight compartment located in the upper half of the three-section 7, which provides buoyancy for the lure and works with the counterweight 10 to keep the lure in an underwater position with its belly down and its back up. The three-section counterweight chamber 31 is a compartment located in the lower half of the three-section 7 where the counterweight 10 is placed, and its function is to work with the buoyancy of the three-section buoyancy chamber 30 to... The lure maintains a belly-down, back-up posture in the water. The transverse shaft hole 32 of the third segment is a hole transversely set at the front end of the third segment 7. Its inner diameter is larger than the diameter of the transverse shaft 5. It is a connecting hole that connects the second segment 6 and the third segment 7 by setting the transverse shaft 5 in the transverse shaft hole 27 of the second segment and the transverse shaft hole 32 of the third segment. The transverse shaft hole 33 of the third segment is a hole transversely set at the rear end of the third segment 7. Its inner diameter is larger than the diameter of the transverse shaft 5. It is a connecting hole that connects the third segment 7 and the tail segment 8 by setting the transverse shaft 5 in the transverse shaft hole 33 of the third segment and the transverse shaft hole 35 of the tail segment.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 9 , Figure 10 As shown, the tail section 8 consists of a tail section outer shell 34, a tail section front transverse shaft hole 35, a tail section buoyancy chamber 36, a tail section counterweight chamber 37, and a tail hook connection point 38. The tail section outer shell 34 is the tail shape of the target lure made of hard material. The tail section front transverse shaft hole 35 is a hole transversely set at the front end of the tail section 8, and its inner diameter is larger than the diameter of the transverse shaft 5. The transverse shaft 5 is set in the rear transverse shaft hole 33 of the third section and the front transverse shaft hole 35 of the tail section, which connects the three sections 7 and the tail section 8 of the lure. The connecting hole and the tail section buoyancy chamber 36 are airtight chambers located in the upper part of the tail section 8. Their function is to provide buoyancy for the lure and work with the weight 10 to keep the lure in a belly-down, back-up position in the water. The tail section weight chamber 37 is a chamber located in the lower part of the tail section 8 where the weight 10 is located. Its function is to work with the buoyancy of the tail section buoyancy chamber 36 to keep the lure in a belly-down, back-up position in the water. The tail hook connection point 38 is located at the tail of the tail section 8 and is the connection point for connecting the hook 11.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 11 As shown, the elastic hammer 9 consists of an elastic wire 39 and a hammer head 40. The elastic wire 39 is a metal wire made of a highly elastic metal, such as nickel-titanium alloy or high-carbon steel. Its length is set to be less than the combined length of the elastic wire 39 and the hammer head 40, which is also less than the horizontal distance between the front and back of the secondary outer shell 24. Its diameter is set such that, when combined with the hammer head 40, it is horizontally positioned inside the secondary outer shell 24. The strength of the elastic wire 39 is such that it can barely lift the hammer head 40 off the bottom of the secondary outer shell 24. The hammer head 40 is a sphere made of a hard material, and its diameter is less than the minimum spacing between the inner compartments of the secondary outer shell. Its weight is set such that, when combined with the elastic wire 39, it is horizontally positioned inside the secondary outer shell 24. The strength of the elastic wire 39 is such that it can barely lift the hammer head 40 off the bottom of the secondary outer shell 24. The function of the elastic hammer 9 is to prevent the lure from moving forward in the water when the angler pulls it. Due to the resistance of the water, the lure is pulled... The shaft 2, U-shaped swivel 3, transverse shaft 5, and transverse shaft holes of each section restrict the direction of the lure's swing, causing the lure to exhibit an up-and-down swinging swimming posture when moving forward. Because the strength of the elastic wire 39, which is horizontally set in the inner compartment of the secondary outer shell 24, is only enough to barely lift the hammer head 40 away from the bottom of the secondary outer shell 24, and because the elastic wire 39 is extremely elastic, when the lure swings up and down continuously as it moves forward, the rhythm of the up-and-down swing of the hammer head 40 driven by the elastic wire 39 is half a beat slower than the rhythm of the up-and-down swing of the secondary outer shell 24. Therefore, the hammer head 40, which is set in the middle of the inner compartment of the secondary outer shell 24 through the elastic wire 39, is deviated from the rhythm of the up-and-down swing of the secondary outer shell 24 under the elastic force of the elastic wire 39, causing the elastic wire 39 to drive the hammer head 40 to continuously hit the upper and lower compartment walls of the secondary outer shell 24, making a sound to attract the attention of the target fish.

[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 9 , Figure 10 As shown, the counterweight 10 is an object with a volume equal to that of each counterweight chamber and a specific gravity greater than water. Its function is to work with the buoyancy of each buoyancy chamber to keep the lure in the water with its belly down and its back up. The fish hook 11 is a fish hook with a size suitable for the body of the lure.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, this invention utilizes the principle of a biomimetic artificial lure that can swing up and down. The lure is simultaneously pulled laterally from both ends of a traction shaft 2, fixing it in place to swing up and down due to water resistance. This mimics the principle that a flag's swaying motion in the wind depends on the direction of the flagpole; if the flagpole is upright, the flag will swing left and right; if the flagpole is horizontal, the flag will swing up and down. Furthermore, the buoyancy of the buoyancy chamber 15 located in the upper part of the fish's body, combined with the gravity of the counterweight 10 located in the lower part of the fish's body, helps maintain the fish's posture, thus mimicking the up-and-down swimming motion of target fish. This invention also utilizes the slow-transmission characteristic of elastic wire in passive force transmission. The strength of the elastic wire 39 is set to a specific value, and after being combined with the hammer head 40, it is horizontally positioned in the second section. Inside the outer shell 24, the strength of the elastic wire 39 is barely enough to lift the hammer head 40 off the bottom of the secondary outer shell 24. Because the elastic wire 39 is extremely elastic, when the lure moves forward and swings up and down, the process of the elastic wire 39 receiving the up-and-down swinging force from the secondary outer shell 24 and transmitting it to the hammer head 40 has a certain delay. This causes the rhythm of the elastic wire 39 driving the hammer head 40 to swing up and down with the secondary outer shell 24 to be half a beat slower than the rhythm of the secondary outer shell 24's up-and-down swinging. Therefore, the hammer head 40, which is horizontally positioned in the middle of the inner compartment of the secondary outer shell 24 by the elastic wire 39, is deviated from the rhythm of the secondary outer shell 24's up-and-down swinging under the elastic force of the elastic wire 39. This causes the elastic wire 39 to drive the hammer head 40 to continuously hit the upper and lower compartment walls of the secondary outer shell 24, making a sound to attract the attention of the target fish.
