Description

Technical Field

[0001] The present invention relates to the technical field of fishing appliances, and particularly to an automatic fishing line retracting and releasing device and a matching reel for assembling fishing lines for hand rods without reels and table fishing rods. Background Art

[0002] A hand rod refers to a fishing rod without a reel, usually composed of multiple nested rod sections, with a length generally ranging from 3 to 10 meters. It is mostly used for freshwater fishing, such as in waters like lakes, rivers, and ponds. The last section of the hand rod is called the rod tip, and the rod tip usually has a rod tip rope or a spherical body for binding and connecting the main line (i.e., the fishing line). The main line has two ends, one end (referred to as the upper end) for connecting to the rod tip, and the other end (referred to as the lower end) for connecting to the line set or fishing hook. Before a fishing activity, the main line is usually stored on a spool in a wound manner and is taken out and installed and connected to the hand rod only when in use. However, this method of storing the main line in combination with the hand rod has some defects and deficiencies during use, which are specifically manifested as follows: 1. In a non-fishing state (i.e., before the line set and fishing hook enter the water), when assembling the fishing line, the operation of retracting and releasing the main line of the hand rod is rather cumbersome and inefficient. For example, when releasing the line, it is necessary to first connect the upper end of the main line to the rod tip, then hold the hand rod with one hand, and the other hand needs to operate the spool to slowly release the line while gradually stretching the fishing rod until the main line is completely released and detached from the spool; conversely, when retracting the line, it is also necessary to retract the hand rod with one hand while operating the spool to retract the line. Therefore, the entire process of retracting and releasing the line is extremely cumbersome and inconvenient, with low efficiency and a waste of precious fishing time; 2. The lower end of the main line is connected to the line set, and the line set includes fishing accessories such as a float seat, lead skin (or lead weight), and a double hook of the sub-line (or other types of fishing hooks). When using a spool to store the main line, if the line set is used as the starting end of winding, the main line will wind around the fishing accessories of the line set during the winding process, resulting in problems such as uneven winding, bulging of the winding body, and bending marks on the main line, causing damage to the main line and a reduction in its strength. Conversely, if the upper end of the main line is used as the starting end of winding, although problems such as uneven winding, bulging of the winding body, and damage to the main line can be avoided, when in use, it is necessary to first release all the main line before connecting it to the rod tip. During this process, the fishing accessories on the line set will first touch the ground, resulting in the main line being easily entangled and knotted with other parts of itself, branches, or grass. In this case, additional time is required to untangle and straighten the main line.

[0003] In view of this, the inventor of the present invention has designed based on years of experience in the field of fishing appliances, considering the structural optimization of the product, and through multiple tests and improvements, made the present invention. Summary of the Invention

The wire winding groove is located at the outer edge of the sandwich space and is arranged around each support column.

[0019] In the spool further provided by the present invention, a storage groove is further arranged beside the linear chute in the sandwich space.

[0020] In the spool further provided by the present invention, the support column is composed of two connecting parts respectively located on the top plate and the bottom plate, and the two connecting parts are detachably connected by the cooperation of an insertion post and a jack.

[0021] Compared with the prior art, the present invention adopts a spring gearbox as the power device, drives the wire winding wheel to rotate through a mechanical transmission mechanism, and realizes that the fishing line on the wire winding wheel can automatically complete the actions of winding and unwinding according to the telescopic stroke of the telescopic fishing rod. At the same time, the braking switch on the housing is also used to brake the transmission of the spring gearbox, effectively pausing the energy release of the spring and keeping the spring in the energy storage state. During the whole working process, the spring gearbox is responsible for using the ratchet winding structure of the input shaft and the driving gear to store mechanical energy by the elastic deformation contraction of the spring. Subsequently, the spring releases the stored energy during the process of elastic deformation recovery. At the same time, the driving gear drives the output gear to operate, drives the output shaft to rotate, and transmits the rotational power to the wire winding wheel, realizing the coaxial rotation of the input shaft and the output shaft. Since the rotational speed of the output shaft is greater than that of the input shaft, a transmission ratio is generated, and the output gear is also affected by the resistance of the gear reduction mechanism, generating a series of transmissions, delaying the release speed of the spring energy, so that the output shaft can rotate at a constant speed, thus meeting the power and telescopic stroke required when the 3-10-meter telescopic fishing rod is winding and unwinding. The wire winding wheel is responsible for the storage of the fishing line in a winding manner and realizes automatic unwinding or winding with the rotational power of the output shaft. In addition, in the present invention, in addition to storing energy in the spring by rotating the input shaft, the rotation of the output shaft can also store energy in the spring. During the energy storage stage, when the wire winding wheel unwinds the fishing line, the output shaft rotates forward, and the wire winding wheel continuously unwinds the fishing line as the telescopic fishing rod is stretched until the fishing line is separated from the wire winding wheel. During this process, the output shaft uses a series of transmissions to reversely drive the input shaft to rotate in the same direction, so that the spring elastically deforms and continuously stores energy; conversely, during the energy release stage, when the wire winding wheel winds the fishing line, one end of the fishing line is wound around the wire winding wheel, and the spring releases energy through elastic deformation, driving the output shaft to rotate backward, and the wire winding wheel continuously winds the fishing line as the telescopic fishing rod contracts until the fishing line is rewound on the wire winding wheel and stored. During this energy storage and release process, the fishing line is always kept in a straightened state under the combined action of the spring gearbox and the telescopic force of the telescopic fishing rod. Also, when the spring gearbox completes energy storage, once the input shaft is released, or at the final stage of the wire winding wheel unwinding the fishing line, the input shaft and the output shaft will lose the external force constraint, and the spring will quickly and automatically elastically deform and release energy. This makes it impossible for the spring to maintain the energy storage state, and further causes the wire winding wheel to lose power when recovering the fishing line and unable to perform normal automatic winding. Therefore, the braking switch can effectively brake the transmission of the spring gearbox, so that the mechanical energy stored in the spring can be stably maintained to reserve a sufficient power source for the next winding.

[0022] It can be seen that through the above structure, during the process of assembling or retrieving the fishing line, the telescopic fishing rod can achieve efficient automatic line casting and retrieving operations, getting rid of the traditional cumbersome manual operations, and saving fishing time and energy. Its energy storage design is more flexible, supporting two energy storage methods: manual winding and automatic winding. When the automatic energy storage is insufficient, manual winding can be used to supplement the energy storage, further enhancing the convenience and flexibility of use. At the same time, under the effective control of the braking switch, the stored mechanical energy can be retained, and the timing of each energy release can be accurately controlled to reserve the necessary power for the next line retrieval.

Detailed Embodiment

[0032] To make the invention objectives, technical solutions, and beneficial effects of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] As Figure 1 、 Figure 2 shown, this embodiment provides an automatic fishing line retracting and releasing device, the structure of which includes a housing 1, a spring gearbox 2, a winding wheel 7, and a brake switch 4. Among them, the spring gearbox is firmly installed inside the housing, while the winding wheel and the brake switch are both arranged outside the housing, and the specific implementation is as follows.

[0034] The housing 1 is an outer shell with a cavity inside, serving as the main part of the automatic fishing line retracting and releasing device. An installation groove 11 for fixing the spring gearbox is provided inside the cavity, and the outer shell is equipped with a cover plate 5 for closing the cavity. The cover plate and the outer shell are connected and fixed through a combination of connecting columns, screw parts, and snap structures, etc. Such a design facilitates the user to perform assembly and disassembly operations.

[0035] The spring gearbox 2, as the power device for automatic wire pay-off and rewinding, is placed in the installation groove 11 of the housing and is firmly fixed inside the housing by the cooperation of the housing and the cover plate. The spring gearbox consists of a box body 21 assembled by a top cover and a bottom cover, and its assembly method combines a plug-in structure and a snap structure. A partition board (not shown in the figure) is also provided between the top cover and the bottom cover, and this partition divides the interior of the box body into an upper chamber and a lower chamber. At the same time, an input shaft 22 and an output shaft 23 are respectively arranged on the box body for the input and output of power.

[0036] Inside the upper chamber, there are a driving gear, an idler gear, an output gear, and a gear reduction mechanism. Among them, the driving gear, the idler gear, and the output gear are all composite gears. Such composite gears refer to an integrated single gear body composed of two transmission tooth structures, and each gear rotates around the same axis. The driving gear consists of a first gear 25 and an internal ratchet. Among them, the internal ratchet is designed coaxially with the first gear and is arranged on the bottom surface of the first gear. An S plate is assembled on the internal ratchet, and the two ends of the S plate are designed with pawls for cooperating with the internal ratchet to form a ratchet mechanism. In addition, a bushing axially extending to the lower chamber is provided in the middle of the bottom surface of the S plate, and this bushing has a fork design for connecting the spring. This part of the ratchet mechanism belongs to the prior art and is not shown in the figure. The idler gear consists of a second gear 26 and a third gear 27 arranged coaxially, and is used for the transmission between the driving gear and the output gear. The second gear and the third gear are in an up-and-down structure. The second gear is below and is designed as a small gear for meshing and driving with the first gear, while the third gear is above and is designed as a large gear. The output gear consists of a fourth gear 28 and a fifth gear 29 arranged coaxially. The fourth gear and the fifth gear are also designed in an up-and-down structure. The fourth gear is above and is designed as a small gear for meshing and driving with the third gear, while the fifth gear is below and is designed as a large gear. The gear reduction mechanism consists of a reduction gear and a speed blocking block 20. The reduction gear is also a composite gear and consists of a sixth gear 20a and a seventh gear 20b. The sixth gear and the seventh gear are in an up-and-down structure. The sixth gear is below and is designed as a small gear for meshing and driving with the fifth gear, while the seventh gear is above and is designed as a large gear. The middle of the speed blocking block is supported by a shaft body and makes a lever-like movement with this shaft body as the fulcrum. When moving, the two ends of the speed blocking block alternately collide with the seventh gear, thereby generating a series of transmissions, reducing the overall transmission speed, and transmitting the movement at a uniform speed. In addition, an opening 24 located above the speed blocking block is also provided on the surface of the box body 21, and this opening exposes the surface of the speed blocking block.

[0037] A spring is provided in the lower chamber. This spring is a flat spiral spring structure that can elastically deform to store energy and then convert the stored energy into mechanical energy through elastic deformation, thereby providing power support for the entire mechanical device. The inner end of the spring is correspondingly connected to the fork formed by the bushing of the S-piece, and the outer end is fixed to the fixed point or fixed position provided in the lower chamber. This part belongs to the prior art and is not shown in the figure.

[0038] The input shaft 22 is a rotating shaft, and its main function is to receive the power transmitted from an external power source. During assembly, the lower end of this output shaft is inserted into the box body 21 and simultaneously passes through the centers of the driving gear and the S-piece. During the assembly process, the S-piece is connected to the lower end of the output shaft in a fastening manner, and at the same time, it is ensured that the shaft end is within the fork of the S-piece, thereby constructing a structure connected to the inner end of the spring. When connecting to the spring, the inner end of the spring is sleeved on this shaft end and placed within the fork of the bushing, and the inner end position of the spring is locked through the fork; the upper end of the output shaft serves as the manual winding operation end and passes through the side of the outer shell (i.e., the opposite side of the cover plate). A handle is installed on this protruding part. This handle uses a circular knob 9, and the surface of the knob is designed with anti-slip strips, so that the entire knob can easily and labor-savingly twist the input shaft for winding operation.

[0039] The output shaft 23 transmits the power processed inside the mechanical device. The lower end of the input shaft is inserted into the box body and is fixedly connected to the center of the output gear. The upper end of the input shaft passes through the cover plate, and this protruding part is used to connect to the center of the winding wheel 7, thereby transmitting the output rotational power to the winding wheel.

[0040] In addition, on the basis of fully considering the working requirements of the fishing line automatic retracting and releasing device, the transmission ratio formed by the mutual cooperation of a series of transmission components such as the above-mentioned driving gear, idler gear, output gear, and the reduction gears and speed blocking blocks of the gear reduction mechanism is set to 1:23. That is to say, when the input shaft rotates 1 circle, the output shaft can complete 23 rotations, that is, the rotational speed of the output shaft is 23 times that of the input shaft. The power generated thereby not only meets the power and stroke requirements for line release or line retraction but also meets the required pulling force of the fishing line, ensuring that the fishing line remains straight during the line retraction stage or line release stage, and avoiding the fishing line from becoming slack due to insufficient power, resulting in the inability to smoothly automatically retract and release the line.

[0041] The winding wheel 7 is responsible for storing the fishing line in a winding manner and at the same time ensuring smooth automatic line release and winding operation when assembling the fishing line on the telescopic fishing rod. The winding wheel is overall circular, and a ring-shaped winding groove is provided on its circumferential surface for winding and releasing the fishing line, and the center of the winding wheel is fixedly connected to the upper end of the output shaft.

[0042] As Figure 1 、 Figure 3, Figure 4 As shown in Figure 4 , the brake switch 4 is responsible for braking the transmission system inside the spring gearbox to ensure that the energy stored in the spring will not be released immediately after winding, and can flexibly control the timing of the release of mechanical energy, providing the necessary power for the subsequent winding of the winding wheel, while avoiding the cumbersome operation of the angler repeatedly winding the spring. The brake switch adopts a handle design. The head 41 of the handle is provided with a shaft hole 42 and a flange 43. The function of the shaft hole is to sleave the head of the handle on a shaft body 3 and control the opening or closing in a lever manner. And the shaft body here is fixed in a notch 13 provided on the surface of the housing 1. The position of this notch is opposite to the upper part of the speed retarder block 20 of the spring gearbox. Above the speed retarder block is an opening 24 on the surface of the spring gearbox housing, which exposes the surface of the speed retarder block and corresponds to the notch. During the actual working process, the user toggles the handle. The handle will swing back and forth on the notch with the shaft body as the rotation center. When the flange 43 of the handle head reaches the opening of the spring gearbox housing, the flange will press down the speed retarder block. At this time, any end of the speed retarder block will snap into the tooth groove of the reduction gear. This action causes a series of transmission components in the spring gearbox to pause working, thus realizing the pause of the spring energy release action. On the contrary, when the flange of the handle head leaves this opening position, the speed retarder block is no longer under pressure restraint and will be released immediately. At this time, the spring gearbox resumes normal transmission work, and the spring energy release action is also started accordingly.

[0043] The transmission ratio of the above-mentioned spring gearbox is set so that the rotational speed of the output shaft is 13 - 25 times that of the input shaft. And this numerical range is fully considered for the telescopic stroke and power requirements of a 3 - 10-meter telescopic fishing rod. If the transmission ratio is lower than 13 times, although it can meet the power requirements for casting or winding to a certain extent, the power provided cannot match the requirements of the complete telescopic stroke of the telescopic fishing rod within the range of 3 - 10 meters. When the transmission ratio is higher than 25 times, although the power can support casting or winding to reach the corresponding stroke, in the winding process, the required power will be significantly insufficient. This will cause the fishing line to become slack during the winding process, and the winding smoothness will drop significantly, affecting the winding efficiency. Therefore, a transmission ratio of 13 - 25 times can meet the power requirements of the telescopic stroke of the telescopic fishing rod, while ensuring sufficient power during the winding process, keeping the fishing line always taut, ensuring the winding smoothness, and improving the efficiency of assembling and retrieving the fishing line.

[0044] Further optimize the design, and an arc-shaped guiding rib 51 is added to the surface of the housing 1. The guiding rib is made by an integral molding process with the cover plate and is located around the periphery of the winding wheel 7. The guiding rib here is arranged on the arc surface in the area of about 4-6 o'clock around the periphery of the winding wheel, and the inner side surface of the guiding rib corresponds to the winding groove of the winding wheel. Through the design of the guiding rib, the guiding rib can effectively guide the fishing line during the winding and unwinding processes of the winding wheel, preventing problems such as the fishing line running off track or getting tangled during the winding process, and ensuring that the fishing line is wound orderly in the winding groove. At the same time, it avoids the fishing line deviating from the track and falling into the gap between the winding wheel and the cover plate, resulting in the winding wheel being stuck and unable to rotate smoothly. Therefore, the existence of the guiding rib can greatly improve the overall working efficiency and reliability of the winding wheel.

[0045] In another optimized design solution of the guiding rib, to meet different usage requirements and scenarios, different forms of guiding ribs can be flexibly selected. On the one hand, arc-shaped guiding ribs with different arc lengths can be used; on the other hand, annular guiding ribs can also be used for replacement setting, so as to restrain and guide the fishing line, ensure that the fishing line runs along the established path, and avoid situations such as running off track or getting tangled.

[0046] In order to further optimize the product structure, the cover plate 5, which is a component of the shell, is also provided with a limiting groove 52 on its surface with the output shaft 23 as the center point. The limiting groove is designed in a circular shape, and its center point is the center of the circle or the axis. At the same time, a circular turntable 6 is also arranged between the cover plate and the winding wheel. The turntable is embedded in the limiting groove, and an appropriate movable gap is reserved between the two, so that the turntable can rotate freely and smoothly in the limiting groove to ensure that it is always in the predetermined motion trajectory. The back axis of the turntable is firmly fixed to the output shaft. When the output shaft is running, the rotational power output by it is transmitted to the turntable, causing the turntable to rotate synchronously with the output shaft. The front of the turntable is connected to the winding wheel, and the two are connected by a plug-in structure in which a plug-in column and a socket are matched. The plug-in structure includes three plug-in columns 61 arranged in a triangular distribution on the front of the turntable, and three sockets are arranged at corresponding positions on the surface of the winding wheel, and each plug-in column corresponds to a socket, thereby forming three groups of plug-in columns and socket combinations, and realizing interference plug-in. Through the organic combination of the above-mentioned structures, the limiting groove and the turntable work together, so that the winding wheel on the turntable can rotate according to the original trajectory, provide stable rotation output, and reduce the deviation or shaking of the winding wheel during rotation, thereby effectively ensuring the smoothness of the process of releasing and reeling. The three groups of posts and sockets distributed in a triangular shape are like three stable fulcrums. They can not only provide stable output and enhance the firmness and stability of the rotation of the winding wheel, but also make the installation and disassembly of the winding wheel easy to achieve, which is convenient for users to replace and use. In addition, the plug-in structure between the turntable and the winding wheel has a variety of implementation methods. In addition to the existing three groups of posts and sockets, two or four groups of posts and sockets can also be used. At the same time, other fastening methods can be used for connection, and even the two can be designed into an integrated structure.

[0047] Furthermore, in the three groups of plug posts 61 and socket combinations, the end face of the insertion end of each plug post is provided with a magnet, and the bottom of the socket hole that matches it is installed with metal iron, and the two together constitute an attractive magnetic attraction component (not shown in the figure). The magnetic attraction component has the following practical functions: on the one hand, when the plug post and the socket are connected, the attraction between the magnet and the metal iron can play a guiding role, so that the plug post can be more accurately and conveniently aligned with the socket for insertion, greatly improving the efficiency and accuracy of installation; on the other hand, in some plug post and socket combinations that do not use an interference connection structure, the magnetic attraction component can provide additional stabilization. In addition, the magnetic attraction component can also be matched with two mutually attractive magnets, or a combination of a magnet and other metals that can be attracted by magnets can be selected.

[0048] like Figure 1 , Figures 4 - 6As shown in the figure, to further optimize the product structure, the above-mentioned spool is jointly composed of a circular top plate 72 and a bottom plate 71. In the overall layout, the top plate is arranged on the outside, while the bottom plate is arranged on the inside and is used to connect with the cover plate 5 of the housing. The top plate and the bottom plate are connected by six support columns 73, which are evenly distributed in the outer edge area between the top plate and the bottom plate and form a circle, thus forming a sandwich space 7a between the top plate and the bottom plate. Here, in addition to playing the role of supporting and connecting between the top plate and the bottom plate, the support columns also have the function of providing a hook for the fishing hook. At the same time, an access opening 7b leading to the inside of the sandwich space is formed between every two adjacent support columns. This access opening can be used to put the fishing accessories on the fishing line set into the sandwich space for hidden storage. In this way, during the winding process, it effectively prevents the fishing line from winding around the fishing accessories, avoiding problems such as the fishing line bulging, uneven winding, and creases on the fishing line. The winding groove 70 of the spool is located on the outer edge of the sandwich space and is arranged around each support column 73. This design uses the support column as the winding surface to provide support for the winding and storage of the fishing line. In addition, a linear chute 77 located on the center line of the bottom plate is provided in the sandwich space. At the same time, a sliding hole 79 corresponding to the linear chute is provided on the surface of the top plate, and the two jointly form a sliding channel. In this sliding channel, a slider 8 is installed. The bottom of the slider is placed in the linear chute and can slide along the linear chute; while the top is provided with a protruding push button 82, which slides in the sliding hole, facilitating the user to control the movement of the slider by pushing the push button. A tension spring (not shown in the figure) is provided at the rear end of the slider. One end of the tension spring is firmly connected to the rear end of the slider, and the other end is fixed to the rear end of the linear chute. With the elastic force of the tension spring, the slider can not only generate an elastic pulling force but also automatically reset after sliding; the front end of the slider is a wire hanging head 81, which is designed as a wire hanging column and can be used to hook the fishing line. When the user pushes the push button to move the slider, the wire hanging head can correspondingly extend and retract into the sandwich space. To achieve the plug-in connection with the turntable, three through holes 75 distributed in a triangle are also provided on the bottom plate of the spool. The three through holes correspond to the plug posts 61 on the turntable one by one, providing insertion openings for the plug-in connection. At the same time, three pipe columns 74 are provided on the inner side surface of the top plate. The three pipe columns extend towards the three through holes on the bottom plate, and the pipe orifice ends thereof are docked with the three through holes, thus forming three jack structures of the spool. Through the cooperation of the three jacks and the plug posts 61 on the turntable, the plug-in connection between the spool and the turntable is realized. In addition, the plug post 61 and the jack structure here can also be connected by the above-mentioned suction magnetic component.

[0049] After the above optimization of the fishing line reel 7, not only can it realize the winding, retracting and paying-out actions during the assembly of the fishing line, but also it has the function of storing the main line and its line set in a winding manner, changing the traditional cumbersome method of having to cut off the line set and reconnect it, greatly improving the reuse efficiency. Moreover, during the process of storing the line set, various fishing accessories such as fishhooks, float seats and sinkers on the line set can be hidden in the sandwich space. Through this storage method, even if the fishing hook of the line set is used as the starting end of the winding, problems such as bulging of the winding body, uneven winding and creases on the fishing line will not occur. In addition, when storing the double hooks of the sub-line, the usual operation is to first hook the two fishing hooks of the double hooks of the sub-line on any support column, and then start the winding operation on the fishing line reel. However, due to the characteristics of the two sub-lines of the double hooks of the sub-line being of different lengths, it is difficult for the long sub-line and the short sub-line to remain flush during the winding process, and the extra length part of the long sub-line will be exposed outside and form a loop. This loop not only affects the winding effect, but also is extremely easy to hook other objects, causing pulling and damaging the winding structure. To solve this problem, a slider for adjusting the line length is specifically set in this optimization of the fishing line reel. The slider is controlled to slide by pushing and twisting, so that the wire hanging post slides out of the sandwich space and hooks the long sub-line. Then, when the push and twist is released, the slider will, under the reset action of the tension spring, smoothly bring the extra length part of the long sub-line into the sandwich space, thereby adjusting the length of the long sub-line to make the winding lengths of the long sub-line and the short sub-line the same. In this way, no loop problem will occur during the winding and storage, making the winding process neater and smoother.

[0050] Furthermore, in the sandwich space 7a of the fishing line reel, a storage groove 7c is also provided beside the sliding channel. This storage groove is mainly used for storing weight-increasing accessories such as sinkers and lead sheets on the line set. When the user uses this fishing line reel to store the main line and its line set, the sinker or lead sheet can be placed in the storage groove along the winding direction, and the winding operation can continue. The setting of this storage groove not only makes the storage space layout of the fishing line reel more reasonable, but also can limit the activities of weight-increasing accessories such as sinkers and lead sheets in the sandwich space, preventing them from scurrying around and hitting the internal structure of the sandwich space, thus ensuring the stability of the fishing line reel structure.

[0051] Furthermore, see Figures 4 - 6, each support column 73 of the above-mentioned winding wheel adopts a plug-in detachable structure. Its implementation method is that each support column consists of two connecting parts, and these two connecting parts adopt a structure of a plug column cooperating with a jack, namely the lower pipe column 76 provided on the bottom plate and the upper plug column 78 provided on the top plate. The pipe orifice of the pipe column is specifically used as the connection socket of the plug column. When the top plate and the bottom plate are connected, the plug column can be accurately inserted into the pipe column and perform a tight interference fit. Through this plug-in structure, it provides great convenience for operations such as assembly, disassembly, maintenance, and replacement of parts. In addition, in another embodiment, to further enhance the stability of the connection between the plug column and the pipe column, during the plugging process of the two, an adhesive can also be used for auxiliary fixation, thereby improving the firmness and reliability of the connection structure.

[0052] Furthermore, see Figure 1 , Figure 4 , the above-mentioned automatic fishing line retracting and releasing device further includes a connecting seat 10. Two connecting holes 103 are provided at the lower end of the connecting seat. At the same time, two connecting columns 12 are provided at the corresponding positions at the upper end of the housing 1. These two connecting columns correspond one-to-one with the connecting holes on the connecting seat, and the two can be detachably connected by plugging. When the connecting hole is sleeved on the connecting column in an interference manner, the connecting seat can be fixed on the housing, thus easily completing the connection and installation; when replacing or adjusting, just pull out the connecting column from the connecting hole, and the separation of the connecting seat and the housing can be achieved. The upper end of the connecting seat is a sleeve 101, and a fastening opening 102 is provided on one side of the sleeve. Through this fastening opening, the sleeve can be sleeved on the corresponding rod section of the telescopic fishing rod in a fastening and buckling manner, such as the rod body at the upper end of the fishing rod grip. When it is necessary to remove the automatic retracting and releasing device from the telescopic fishing rod, the connecting seat can also be easily disassembled from the telescopic fishing rod through this break. Through the design of the connecting seat, the installation of the automatic fishing line retracting and releasing device to the telescopic fishing rod and its separation from the telescopic fishing rod become extremely simple, and it can be disassembled and assembled at any time according to the actual use situation, making it more flexible to use. In addition, in another embodiment, the connecting seat and the housing are made by an integral molding process. This process makes the connecting seat and the housing an inseparable whole. Compared with the design of using a detachable connection, the integral molding connecting seat and housing are more stable in structure, thereby improving the reliability of the overall structure.

[0053] Such as Figure 7As shown, in the night fishing scenario, anglers often face the need to bait the fishing hook. Due to insufficient light, a night fishing light is generally equipped. There are two common types: flashlight-style lighting devices, electronic floats, etc. The flashlight-style lighting device is relatively heavy, cumbersome to carry and install, and easily attracts mosquitoes to gather. The electronic float has components such as a battery inside and requires continuous power supply during use. As the fishing time extends, the power consumption becomes more obvious, and the battery needs to be frequently replaced. This not only increases the usage cost but may also cause the lighting to be interrupted due to failure to replace the battery in time, affecting the baiting operation. In view of the defects of the above two types of night fishing lights, the inventor provides another lighting optimization solution. An illuminating device is installed on the housing, and the illuminating device is fixed to the lower side of the housing (not shown in the figure). The illuminating device includes a battery 112, an LED lamp 110, and an angle switch 114. The positive electrodes of the battery and the LED lamp are connected by a first wire 111. The angle switch includes a sealed hollow tube, a conductive bead, a second wire 115, and a third wire 113. The conductive bead is formed of mercury and can move in a rolling manner within the hollow tube. The input end of the second wire 115 is connected to the negative electrode of the LED lamp, and its output end is inserted into the vacuum tube. At the same time, the input end of the third wire 113 is also inserted into the vacuum tube and is separated from the input end of the second wire. Its output end is connected to the negative electrode of the battery. The working principle is that when the conductive bead moves within the hollow tube to simultaneously contact the output end of the second wire and the input end of the third wire, the angle switch is in a conducting state, and at this time, a complete circuit is formed, and the LED lamp continuously emits light. Conversely, if the conductive bead moves within the hollow tube to a position far from these two access ends, the angle switch is in an off state, and the LED lamp is extinguished.

[0054] In addition, when baiting during night fishing, the common practice is to first cast the fishing hook in front of the angler, which is exactly within the range of the grip of the telescopic fishing rod. In order to enable the lighting device to automatically light up and illuminate this area, when installing the above-mentioned lighting device, the access end of the hollow tube connected to the output end of the second wire and the input end of the third wire faces the angler, that is, the access end of the hollow tube is set inward, and the opposite non-access end is set outward. Through this setting, when the angler raises the telescopic fishing rod and casts the fishing hook back towards himself, the conductive bead will automatically move towards the output end of the second wire and the input end of the third wire under the action of gravity and the inertia generated by the movement of the rod body, thereby conducting the circuit, and the lighting device will automatically light up, providing sufficient lighting for the angler to bait the fishing hook, and the operation is extremely convenient; conversely, when the angler finishes baiting, casts the fishing hook forward, and the fishing rod tilts slightly forward, the conductive bead will move towards the non-access end of the hollow tube due to the displacement generated by gravity and the tilt of the rod body, and the circuit will be disconnected immediately, and the LED light will automatically go out. This method of controlling the lighting device through the angle switch to achieve the automatic on or off function of the lighting not only effectively saves power consumption and prolongs the battery usage time, but also enables the lighting to light up in time to provide lighting when needed, facilitating the angler to bait the fishing hook; when lighting is not required, it can automatically go out, avoiding the trouble of attracting mosquitoes due to lighting. In this way, the convenience and comfort during night fishing are greatly improved, creating a better night fishing experience for anglers.

[0055] As Figure 8 shown, in order to further optimize the circuit structure of the above-mentioned lighting device, a single-pole double-throw switch 116 is added between the third wire 113 and the negative pole of the battery 112. The output end of the single-pole double-throw switch is connected to the negative pole of the battery. The first output contact A of the single-pole double-throw switch is connected to the output end of the third wire 113. At the same time, its second output contact B is connected to the negative pole of the LED light through the fourth wire 117, so that the LED light 110 and the angle switch 114 form a parallel circuit structure. In this circuit, when the single-pole double-throw switch is switched to connect the first output contact A, the entire circuit forms a closed circuit. At this time, with the tilting action of the fishing rod, the conductive bead in the angle switch will move accordingly, thereby automatically controlling the on and off of the circuit, realizing the automatic lighting or extinguishing of the lighting according to the posture of the fishing rod; if the single-pole double-throw switch is placed in the middle position, the circuit will be immediately disconnected, the lighting will go out, and the angle switch will also fail, effectively avoiding unnecessary power consumption; when the switch is switched to connect the second output contact B, the lighting will enter the constant-on state. It can be seen that by adding a single-pole double-throw switch, the angler can freely and accurately select the lighting or extinguishing mode of the lighting according to the light conditions of the actual fishing environment, his own operation habits and specific needs, significantly improving the use experience of the lighting equipment during night fishing and providing a strong guarantee for the smooth development of night fishing activities.
