Description

Technical Field

[0001] This invention relates to the field of lighting devices, and in particular to a variable focus fishing light. Background Technology

[0002] Nowadays, people enjoy fishing to cultivate their character and temperament. When fishing at night, it is necessary to use a special fishing light to observe the subtle movements of the float in order to accurately judge the fish's behavior. Night fishing enthusiasts have high requirements for the performance of fishing lights, because the size of the light spot and the position of the illumination are required to suit different situations.

[0003] Current fishing lights are structurally similar to ordinary flashlights, with the head and body generally fixed. Most cannot adjust the beam size. Even those that can adjust the beam size require a movable lens, achieved by extending or retracting the entire lens assembly. Furthermore, the fishing light has an internal aperture; moving the lens assembly causes internal air compression or expansion, potentially damaging internal optical components and reducing their lifespan. Repeated movement of the lens assembly can also damage the waterproof seal, compressing the waterproof seal. Additionally, the extended lens assembly changes the center of gravity after installation, requiring adjustment of the entire light fixture's angle to illuminate the original area, making it inconvenient to use.

[0004] The inventors discovered that the existing technology has at least the following problem: the fishing lamp cannot quickly and conveniently adjust the size of the illuminated spot. Summary of the Invention

[0005] The purpose of this invention is to provide a variable focus fishing light that can solve the problem that fishing lights cannot quickly and conveniently adjust the size of the illuminated spot.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a variable-focus fishing light, including a battery assembly comprising a battery pack and a movable cylinder. A first toothed groove is arranged in a ring around one end of the movable cylinder. A variable-focus assembly includes a rotating cylinder, a support ring, and a rotating bracket. Both the rotating cylinder and the support ring are hollow cylindrical rings. A second toothed groove is provided on the inner wall surface of one end of the rotating cylinder. The support ring has two rotating grooves on its surface, with the length direction of the rotating grooves forming an acute angle with the axis of the support ring. The rotating bracket includes a rotating base and two connecting feet. Both connecting feet are fixedly connected to the periphery of one side of the rotating base. A rotating boss is provided at the end of each connecting foot away from the rotating base. A rotating cylinder is fitted outside the movable cylinder to allow the first tooth groove to mesh with the second tooth groove. A support ring is fitted outside the rotating bracket, and two rotating bosses respectively engage with two rotating grooves. The rotating cylinder is fitted outside the support ring and connected to the support ring, so that the rotating cylinder drives the support ring to rotate while the rotating bosses slide along the rotating grooves, thereby driving the rotating bracket to rotate and translate along the optical axis. The optical assembly includes a lens housing, a light source, and a concave lens. The lens housing is a hollow cylindrical ring. The battery pack is connected to the light source. The lens housing is fitted at the end of the support ring away from the movable cylinder. The light source is fixed inside the lens housing. The concave lens is fixed inside the rotating base, and the light source is located between the concave lens and the support ring.

[0007] Additionally, a battery slot is provided at one end of the movable cylinder, and the battery pack is embedded in the battery slot. The inner wall surface of the rotating cylinder has a fastening groove, the length of which is parallel to the axis of the rotating cylinder. The surface of the support ring also has a fastening boss. The rotating cylinder is fitted over the support ring so that the fastening boss engages with the fastening groove. The optical components also include a copper substrate, a fixing ring, a first lens, a second lens, and a double-sided convex lens. The end of the lens housing near the support ring has a secondary countersunk hole. The copper substrate and the fixing ring are respectively fixed within the secondary countersunk hole, with the copper substrate located between the fixing ring and the movable cylinder. A light source is located on the surface of the copper substrate facing the fixing ring. The first and second lenses are fixed within the fixing ring, with the first lens located between the light source and the second lens. The double-sided convex lens is fixed inside the end of the lens housing furthest from the rotating cylinder. By moving the movable cylinder to create the battery slot, the battery pack can be concealed within the movable cylinder, improving the overall aesthetics and integration of the variable-focus fishing light. By providing a fastening groove on the inner wall surface of the rotating cylinder, with the length direction of the fastening groove parallel to the axis direction of the rotating cylinder, and a fastening boss on the surface of the support ring, the rotating cylinder is also sleeved on the outside of the support ring so that the fastening boss and the fastening groove cooperate, so that the rotating cylinder can drive the support ring to rotate after being sleeved on the outside of the support ring, and can slide along the surface of the support ring at the same time, which facilitates the movement of the movable cylinder and the separation of the first tooth groove and the second tooth groove. The optical components also include a copper substrate, a fixing ring, a first lens, a second lens, and a double-sided convex lens. The lens housing has a secondary countersunk hole at one end near the support ring. The copper substrate and the fixing ring are fixed within the secondary countersunk hole, with the copper substrate positioned between the fixing ring and the movable cylinder. A light source is located on the surface of the copper substrate facing the fixing ring. The first and second lenses are fixed within the fixing ring, with the first lens positioned between the light source and the second lens. The double-sided convex lens is fixed inside the lens housing at the end furthest from the rotating cylinder. This allows the copper substrate to fix the light source, improving its heat dissipation and extending its lifespan. The fixing ring also secures the first and second lenses, positioning them directly in front of the light source to converge the emitted light. Finally, a concave lens and a double-sided convex lens are positioned in front of the first and second lenses to converge and diverge the light, improving the light adjustment range of the variable-focus fishing light.

[0008] In addition, the inner wall surface of the rotating cylinder away from the movable cylinder is provided with a ring of third tooth grooves. The lens housing has multiple buffer holes arranged at equal intervals around the periphery of the end near the support ring. Each buffer hole contains a spring block. The end of the spring block facing the inside of the lens housing is connected to a buffer spring. The end of the buffer spring away from the spring block is connected to a buffer sleeve inside the lens housing. The end of the spring block facing the outside of the buffer hole is provided with a meshing cone end so that when the rotating cylinder is sleeved outside the support ring, the meshing cone end meshes with the third tooth groove. The surface of the lens housing facing the support ring is provided with multiple positioning pins. The axis of the positioning pins is parallel to the axis of the support ring. The spring block is provided with positioning holes. The axis of the positioning holes is parallel to the axis of the positioning pins so that the positioning pins pass through the positioning holes. Multiple buffer holes are evenly spaced along the periphery of the lens housing near the support ring. Each buffer hole contains a spring block, and the end of each spring block facing inwards from the lens housing is connected to a buffer spring. The end of the buffer spring away from the spring block is connected to a buffer sleeve inside the lens housing. The end of each spring block facing outwards from the buffer hole has a meshing cone end, so that when the rotating cylinder is fitted outside the support ring, the meshing cone end engages with the third tooth groove. Multiple positioning pins are located on the surface of the lens housing facing the support ring, with the axis of the positioning pins parallel to the axis of the support ring. Each spring block has a positioning hole, with the axis of the positioning hole parallel to the axis of the positioning pin, so that the positioning pin passes through the positioning hole. When the rotating cylinder rotates relative to the support ring, the spring blocks engaging with the third tooth groove sequentially spring up and press down, producing a sound. This allows the user to feel the rotation angle and precisely adjust the variable-focus fishing light. The multiple positioning pins also position the spring blocks, preventing them from shifting.

[0009] In addition, the lens housing has multiple arc-shaped buffer grooves on its periphery near the support ring. Each arc-shaped buffer groove contains an arc block. The end of the arc block facing inwards from the lens housing is connected to multiple buffer springs, and the end of the buffer springs away from the arc block is connected to a buffer sleeve inside the lens housing. The surface of the arc block facing outwards from the buffer hole has a fourth toothed groove, so that when the rotating cylinder is fitted outside the support ring, the fourth toothed groove engages with the third toothed groove. By having multiple arc-shaped buffer grooves on the periphery of the lens housing near the support ring, each arc-shaped buffer groove contains an arc block. The end of the arc block facing inwards from the lens housing is connected to multiple buffer springs, and the end of the buffer springs away from the arc block is connected to a buffer sleeve inside the lens housing. The surface of the arc block facing outwards from the buffer hole has a fourth toothed groove, so that when the rotating cylinder is fitted outside the support ring, the fourth toothed groove engages with the third toothed groove. This causes the arc block, which engages with the third toothed groove, to repeatedly press down and spring up when the rotating cylinder rotates relative to the support ring, improving the user's feel during rotation and making it easier for the user to feel the rotation angle for precise adjustment of the variable focus fishing light.

[0010] In addition, the lens housing surface facing the support ring is provided with multiple locating pins, the axes of which are parallel to the axis of the support ring. Each end of the arc block has a locating hole, the axis of which is parallel to the axis of the locating pin, allowing the locating pin to pass through. By providing multiple locating pins on the lens housing surface facing the support ring, with the axes of the locating pins parallel to the axis of the support ring, and providing locating holes at each end of the arc block with the axes of the locating holes parallel to the axis of the locating pin, the ends of the arc block are positioned, preventing displacement of the arc block.

[0011] Additionally, a reset post is provided on the surface of the rotating base facing the support ring, and a reset spring is fitted onto the reset post. A reset countersunk hole is provided at the corresponding position on the lens housing, and the reset post and reset spring are inserted into the reset countersunk hole. By providing a reset post on the surface of the rotating base facing the support ring, and a reset spring fitted onto the reset post, and a reset countersunk hole at the corresponding position on the lens housing, after the movable cylinder is pulled out and rotated to adjust the light of the variable focus fishing light, the retraction of the reset spring helps the movable cylinder to reset, completing the engagement of the first and second toothed grooves.

[0012] In addition, the movable cylinder and the lens housing both have multiple sealing grooves around their periphery. Each groove contains a sealing ring, which is sandwiched between the rotating cylinder and the movable cylinder, and between the rotating cylinder and the lens housing. By providing multiple sealing grooves around the movable cylinder and the lens housing, and by placing sealing rings within each groove, the variable-focus fishing light is waterproofed, preventing moisture from flowing in between these areas and damaging the internal components of the light.

[0013] In addition, the rotating base has a first stepped hole inside, in which the concave lens is fixed. The lens housing, at the end furthest from the rotating cylinder, has a second stepped hole inside, in which the double-convex lens is fixed. By having a first stepped hole inside the rotating base, in which the concave lens is fixed, and a second stepped hole at the end of the lens housing furthest from the rotating cylinder, in which the double-convex lens is fixed, the concave lens and the double-convex lens can be embedded in the rotating base and the lens housing, improving their stability.

[0014] In addition, there are two locking bosses and two locking slots. The inner surface of the lens housing has two slotted through holes, the axes of which are parallel to the axis of the lens housing, so that each slotted through hole mates with one locking boss. By providing two locking bosses and two locking slots, and two slotted through holes on the inner surface of the lens housing, with the axes of which are parallel to the axis of the lens housing, so that each slotted through hole mates with one locking boss, both locking bosses are subjected to force simultaneously, improving the rotational stability of the support ring. At the same time, the slotted through holes prevent the lens housing from interfering with the locking bosses during installation.

[0015] In addition, both the outer surfaces of the movable cylinder and the rotating cylinder are textured with anti-slip patterns, and a pull ring is provided at the end of the movable cylinder furthest from the rotating cylinder. By providing anti-slip patterns on the outer surfaces of both the movable cylinder and the rotating cylinder, and by providing a pull ring at the end of the movable cylinder furthest from the rotating cylinder, users can easily grip the movable cylinder and the rotating cylinder and pull out the movable cylinder, improving ease of use.

[0016] Compared to existing technologies, this invention, when light adjustment is needed, involves pulling the movable cylinder backward to separate the first and second toothed grooves. Simultaneously, rotating the cylinder causes the support ring to rotate, which in turn causes the rotating boss to slide along the inclined rotating groove. This rotating boss then drives the rotating bracket to rotate, moving it away from or towards the movable cylinder, thus changing the distance between the concave lens and the light source within the rotating bracket, thereby adjusting the light. After adjustment, pushing the movable cylinder forward engages the first and second toothed grooves. Once engaged, the cylinder cannot rotate relative to the support ring, thus securing it. Firstly, throughout the adjustment process, the concave lens moves within the cavity, preventing compression or expansion of the vacuum gas inside. Simultaneously, the waterproof ring does not move back and forth and wear down, ensuring waterproof performance. Secondly, the overall length of the lamp remains unchanged during adjustment, preserving the center of gravity of the variable-focus fishing lamp. When mounted on a fishing bracket, the center of gravity remains constant, eliminating the need to adjust the support point, making it convenient, safe, and extending the lamp's lifespan. Finally, by moving the concave lens, all the light rays pass through the concave lens and exit the lamp body, resulting in higher luminous flux. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the various embodiments of this invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this invention to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0026] Nowadays, people enjoy fishing to cultivate their character and temperament. When fishing at night, it is necessary to use a special fishing light to observe the subtle movements of the float in order to accurately judge the fish's behavior. Night fishing enthusiasts have high requirements for the performance of fishing lights, because the size of the light spot and the position of the illumination are required to suit different situations.

[0027] Current fishing lights are structurally similar to ordinary flashlights, with the head and body generally fixed. Most cannot adjust the beam size. Even those that can adjust the beam size require a movable lens, achieved by extending or retracting the entire lens assembly. Furthermore, the fishing light has an internal aperture; moving the lens assembly causes internal air compression or expansion, potentially damaging internal optical components and reducing their lifespan. Repeated movement of the lens assembly can also damage the waterproof seal, compressing the waterproof seal. Additionally, the extended lens assembly changes the center of gravity after installation, requiring adjustment of the entire light fixture's angle to illuminate the original area, making it inconvenient to use.

[0028] The inventors discovered that the existing technology has at least the following problem: the fishing lamp cannot quickly and conveniently adjust the size of the illuminated spot.

[0029] The first embodiment of the present invention relates to a variable focus fishing light, such as... Figures 1 to 2 As shown, the variable-focus fishing light in this embodiment includes a battery assembly 100, a zoom assembly 200, and an optical assembly 300. The battery assembly 100 includes a battery pack 110 and a movable cylindrical body 120. A ring of first toothed grooves 121 is arranged around the periphery of one end of the movable cylindrical body 120. The zoom assembly 200 includes a rotating cylinder 210, a support ring 220, and a rotating bracket 230. Both the rotating cylinder 210 and the support ring 220 are hollow cylindrical rings. A ring of second toothed grooves 211 is provided on the inner wall surface of one end of the rotating cylinder 210. The support ring 220 has two rotating grooves 221 on its surface. The length direction of the rotating grooves 221 forms an acute angle with the axis of the support ring 220. The rotating bracket 230 includes a rotating base 231 and two connecting feet 232. Both connecting feet 232 are fixedly connected to the periphery of one side of the rotating base 231, and the connecting feet 232 are located away from the rotating base 231. One end of each of the 31 is provided with a rotating boss 233. The rotating cylinder 210 is sleeved on the outside of the movable cylinder 120 so that the first tooth groove 121 and the second tooth groove 211 mesh. The support ring 220 is sleeved on the outside of the rotating bracket 230 and the two rotating bosses 233 respectively cooperate with the two rotating grooves 221. The rotating cylinder 210 is sleeved on the outside of the support ring 220 and connected to the support ring 220 so that the rotating cylinder 210 drives the support ring 220 to rotate while the rotating bosses 233 slide along the rotating grooves 221, thereby driving the rotating bracket 230 to rotate and translate along the optical axis. The optical assembly 300 includes a lens housing 310, a light source 320, and a concave lens 330. The lens housing 310 is a hollow cylindrical ring. The battery pack 110 is connected to the light source 320. The lens housing 310 is sleeved on the end of the support ring 220 away from the movable cylinder 120. The light source 320 is fixed inside the lens housing 310. The concave lens 330 is fixed inside the rotating base 231, and the light source 320 is located between the concave lens 330 and the support ring 220.

[0030] The working principle of the variable focus fishing light in this embodiment is as follows: Figures 3 to 4As shown, when light needs to be adjusted, the movable cylinder 120 is pulled back, causing the first toothed groove 121 and the second toothed groove 211 to separate. At this time, the rotating cylinder 210 and the support ring 220 can rotate relative to each other. Hold the rotating cylinder 210 and rotate it, causing the rotating cylinder 210 to drive the support ring 220 to rotate. The rotating base 231 is connected to the support frame via rotating bosses 233 on two connecting feet 232. The surface of the support ring 220 is provided with two rotating grooves 221, which surround the surface of the support ring 220. The length direction of the rotating grooves 221 forms an acute angle with the axis of the support ring 220. The two rotating grooves 221 are symmetrical about the center of the support ring 220. The rotating bosses 233 cooperate with the rotating grooves 221. When the support ring 220 rotates, the rotating support ring 220 drives the rotating bosses 233 to slide along the inclined rotating grooves 221. In turn, the rotating bosses 233 drive the connecting feet 232 and the rotating base 231 to rotate and move in a direction away from or towards the movable cylinder 120, thereby changing the distance between the concave lens 330 in the rotating base 231 and the light source 320 in the lens housing 310, thus completing the adjustment of the light.

[0031] After adjustment, the movable cylinder 120 is pushed toward the support ring 220, so that the first tooth groove 121 and the second tooth groove 211 are engaged. The engaged first tooth groove 121 and the second tooth groove 211 can prevent the rotating cylinder 210 from rotating, thereby stabilizing the adjustment system.

[0032] In this embodiment, when light adjustment is needed, the movable cylinder 120 is pulled backward, causing the first toothed groove 121 and the second toothed groove 211 to separate. Simultaneously, the rotating cylinder 210 is rotated, causing the support ring 220 to rotate. The rotating support ring 220 causes the rotating boss 233 to slide along the inclined rotating groove 221, thereby causing the rotating bracket 230 to rotate and move away from or closer to the movable cylinder 120. This changes the distance between the concave lens 330 and the light source 320 within the rotating bracket 230, thus adjusting the light. After adjustment, the movable cylinder 120 is pushed forward to engage the first toothed groove 121 and the second toothed groove 211. After engagement, the rotating cylinder 210 cannot rotate relative to the support ring 220, thus achieving fixation. Firstly, throughout the adjustment process, the concave lens 330 moves within the cavity, preventing compression or expansion of the vacuum gas inside. Simultaneously, the waterproof ring does not move back and forth and wear down, ensuring waterproof performance. Secondly, during the adjustment process, the overall length of the lamp remains unchanged, and the center of gravity of the variable-focus fishing lamp remains the same. When installed on a fishing bracket, the center of gravity does not change, eliminating the need to adjust the center of gravity support point. This makes it convenient to use, ensures high safety, and extends the lamp's lifespan. Finally, by moving the concave lens 330, all light rays pass through the concave lens 330 before exiting the lamp body, resulting in higher luminous flux.

[0033] like Figures 5 to 8As shown, a battery slot is provided at one end of the movable cylinder 120, and the battery pack 110 is embedded in the battery slot; the inner wall surface of the rotating cylinder 210 is provided with a fastening groove 212, the length direction of the fastening groove 212 is parallel to the axial direction of the rotating cylinder 210, and the surface of the support ring 220 is also provided with a fastening boss 222. The rotating cylinder 210 is also sleeved on the outside of the support ring 220 so that the fastening boss 222 cooperates with the fastening groove 212; the optical component 300 also includes a copper substrate 340, a fixing ring 350, a first lens 360, a second lens 370, and a double-sided convex lens 380. The lens housing 310 has a secondary countersunk hole at one end near the support ring 220. The copper substrate 340 and the fixing ring 350 are respectively fixed within the secondary countersunk hole, with the copper substrate 340 located between the fixing ring 350 and the movable cylinder 120. A light source 320 is provided on the surface of the copper substrate 340 facing the fixing ring 350. The first lens 360 and the second lens 370 are fixed within the fixing ring 350, with the first lens 360 located between the light source 320 and the second lens 370. A double-convex lens 380 is fixed inside the end of the lens housing 310 away from the rotating cylinder 210. By moving the movable cylinder 120 to provide a battery slot, the battery pack 110 can be concealed within the movable cylinder 120, improving the overall aesthetics and integration of the variable-focus fishing light. By providing a fastening groove 212 on the inner wall surface of the rotating cylinder 210, with the length direction of the fastening groove 212 parallel to the axial direction of the rotating cylinder 210, and a fastening boss 222 on the surface of the support ring 220, the rotating cylinder 210 is also sleeved on the outside of the support ring 220 so that the fastening boss 222 cooperates with the fastening groove 212, so that after the rotating cylinder 210 is sleeved on the outside of the support ring 220, it can drive the support ring 220 to rotate, and at the same time slide along the surface of the support ring 220, which facilitates the movement of the movable cylinder 120 and the separation of the first tooth groove 121 and the second tooth groove 211.The optical assembly 300 also includes a copper substrate 340, a fixing ring 350, a first lens 360, a second lens 370, and a biconvex lens 380. The lens housing 310 has a secondary countersunk hole at one end near the support ring 220. The copper substrate 340 and the fixing ring 350 are respectively fixed within the secondary countersunk hole, with the copper substrate 340 located between the fixing ring 350 and the movable cylinder 120. A light source 320 is provided on the surface of the copper substrate 340 facing the fixing ring 350. The first lens 360 and the second lens 370 are fixed within the fixing ring 350, with the first lens 360 located between the light source 320 and the second lens 370. The biconvex lens 380... Lens 380 is fixed inside the end of lens housing 310 away from rotating cylinder 210, so that copper substrate 340 is used to fix light source 320, improve the heat dissipation capacity of light source 320, and extend the service life of light source 320. At the same time, fixing ring 350 is used to fix and install first lens 360 and second lens 370, so that first lens 360 and second lens 370 are directly in front of light source 320, and are used to converge the light emitted by light source 320. Finally, concave lens 330 and double convex lens 380 are set in front of first lens 360 and second lens 370 to converge and diverge light, and improve the light adjustment range of variable focus fishing lamp.

[0034] It is understood that the light source 320 is an LED light source 320, which is mounted on the copper substrate 340 by soldering. The heat generated by the light source 320 during illumination is dissipated through the copper substrate 340, improving the lifespan of the light source 320. Both the first lens 360 and the second lens 370 are made of glass and are fixed in the fixing ring 350, with the first lens 360 and second lens 370 located directly in front of the light source 320. When the rotating cylinder 210 is rotated, the rotating base 231 drives the concave lens 330 to move forward and backward within the cavity. The light emitted by the light source 320, after passing through the first lens 360 and second lens 370, has a fixed angle. When the light passes through the concave lens 330 and the position of the concave lens 330 changes, the angle of the light rays hitting the double-sided convex lens 380 changes, thereby achieving the adjustment of high beam and low beam. Simultaneously, the movement of the concave lens 330 can also change the size of the light spot.

[0035] The inner wall surface of the rotating cylinder 210, away from the movable cylinder 120, is provided with a ring of third toothed grooves 213. Multiple buffer holes 311 are evenly spaced along the periphery of the end of the lens housing 310 near the support ring 220. Each buffer hole 311 contains a spring block 312. The end of the spring block 312 facing the inside of the lens housing 310 is connected to a buffer spring 313. The end of the buffer spring 313 away from the spring block 312 is connected to a buffer sleeve 314 inside the lens housing 310. The spring block 31... 2. One end facing the outside of the buffer hole 311 is provided with a meshing cone end, so that when the rotating cylinder 210 is sleeved on the outside of the support ring 220, the meshing cone end is engaged with the third tooth groove 213. The surface of the lens housing 310 facing the support ring 220 is provided with multiple positioning pins 315. The axis of the positioning pin 315 is arranged parallel to the axis of the support ring 220. The spring block 312 is provided with a positioning hole 316. The axis of the positioning hole 316 is arranged parallel to the axis of the positioning pin 315, so that the positioning pin 315 passes through the positioning hole 316. Multiple buffer holes 311 are evenly spaced along the periphery of the end of the lens housing 310 near the support ring 220. Each buffer hole 311 contains a spring block 312. The end of each spring block 312 facing inwards from the lens housing 310 is connected to a buffer spring 313. The end of the buffer spring 313 away from the spring block 312 is connected to a buffer sleeve 314 inside the lens housing 310. The end of each spring block 312 facing outwards from the buffer hole 311 has a meshing cone end, so that when the rotating cylinder 210 is fitted onto the outside of the support ring 220, the meshing cone end engages with the third tooth groove 213. The outer casing 310 has multiple positioning pins 315 on its surface facing the support ring 220. The axis of the positioning pins 315 is parallel to the axis of the support ring 220. The spring block 312 has a positioning hole 316, the axis of which is parallel to the axis of the positioning pin 315, so that the positioning pin 315 passes through the positioning hole 316. When the rotating drum 210 rotates relative to the support ring 220, the spring block 312, which meshes with the third tooth groove 213, moves up and down in sequence, making a sound. This allows the user to feel the angle of rotation and make precise adjustments to the variable focus fishing light. The multiple positioning pins 315 also position the spring block 312, preventing it from shifting.

[0036] When the cone-shaped head of the spring block 312 engages with the third tooth groove 213 inside the rotating cylinder 210, the spring block 312 repeatedly engages and disengages during rotation, producing a clicking sound to enhance the tactile feedback and allow the user to know that the internal parts are moving, making it easier for the user to make adjustments.

[0037] The lens housing 310 has multiple arc-shaped buffer grooves on its periphery near the support ring 220. Each arc-shaped buffer groove contains an arc block.
