Description

Technical Field

[0001] This invention belongs to the field of fishing line tensile testing technology, specifically relating to a long-distance fishing line tensile testing machine and its testing method. Background Technology

[0002] A fishing line tensile strength testing device, disclosed in Chinese Patent Application No. 202321641417.7, includes a top cover and a device base. Base pads are fixedly connected to the four corners of the bottom of the device base. A clamping mechanism is provided on the top of the device base, comprising a fixing block, a first clamping block, a first rotating arm, a second rotating arm, and a second clamping block. The bottom of the fixing block is fixedly connected to the upper surface of the device base. This fishing line tensile strength testing device effectively solves the problem that vibration and shaking during actual use can cause the fishing line to slip out of the device, making it impossible to effectively obtain the tensile strength of the fishing line and resulting in low efficiency in fishing line tensile strength testing. During operation, the device allows for convenient and secure clamping of the fishing line to be tested and prevents the fishing line from slipping out during operation, thereby improving the usability of the device.

[0003] Although the aforementioned patents achieve stable clamping of fishing lines, the following problems still exist: 1. Existing fishing line tensile testing equipment is mostly designed for short gauge fishing lines. The equipment structure is simple and can only complete the tensile testing of short sections of fishing lines. It cannot adapt to the overall testing needs of fishing lines with a distance of 5m or more; 2. Traditional testing equipment mostly uses clamps to rigidly clamp the fishing line. During the clamping process, the fishing line is easily squeezed and cut, causing the fishing line to break prematurely at the clamping position, resulting in distorted test data.

[0004] Therefore, this application provides a long-distance fishing line tensile testing machine and its testing method to meet the requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a long-distance fishing line tensile testing machine and its testing method to solve the problems mentioned in the background art. The long-distance fishing line tensile testing machine and its testing method provided by this invention have the advantages of effectively improving the testing capability for long-distance fishing lines, simple fixing method, and quick line unloading.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a long-distance fishing line tensile strength testing machine, comprising a base, with columns and a display device fixedly connected to the top two sides of the base respectively, a control button provided on the top of the base, and a first fixing component provided on the top of the columns; a guide wheel located on one side of the columns, the guide wheel being connected to a ball screw inside the columns, the guide wheel being used to drive the fishing line to be tested for tensile strength testing; and a second fixing component being used to fix one end of the fishing line to be tested.

[0007] To ensure the accuracy of the fishing line tensile test data, the first fixing component further includes a mounting plate fixedly connected to the top of the post, with a tail post fixedly connected to one side of the mounting plate, and the tail post and guide wheel located in the same vertical plane.

[0008] To enable the testing machine to test the tensile strength of fishing lines over long distances, the second fixing component further includes a fixing plate fixedly connected to the wall, an extension post fixedly connected to the side of the fixing plate near the testing machine, and an end post sleeved on the outer wall of the extension post; it also includes a line loosening unit for quickly unloading the fishing line after it breaks during testing.

[0009] The loosening unit is provided with an installation position by means of a loosening groove and a connecting post. Furthermore, a loosening groove is formed on the outer wall of the end post, with one end extending through the axial direction of the end post. A connecting post is fixedly connected to the side of the end post near the end post through the loosening groove.

[0010] To facilitate the quick removal of fishing line tangled on the end post surface after the fishing line breaks, the line loosening unit further includes a line loosening plate disposed on the line loosening groove. The line loosening plate is adapted to the line loosening groove. An elastic strip is fixedly connected to one end of the line loosening plate near the connecting post. A connecting ring is fixedly connected to one end of the elastic strip. The connecting ring is sleeved and fixed to the outer wall of the connecting post.

[0011] To facilitate workers in winding the fishing line according to the established method, the outer walls of the loosening plate are further fixedly connected with line holders at both ends.

[0012] To facilitate the insertion of the fishing line into the line holder, the line holder is made of rubber, with a slot at the top. The top of the slot is an open structure that unfolds outwards, and the bottom of the slot is a groove structure with a diameter smaller than that of the fishing line.

[0013] To achieve detachable fixing of the second fixing component, a mounting component is further included. The mounting component includes an end plate fixedly installed on the wall surface. A slide rail base is fixedly installed on one side of the end plate. Two sets of auxiliary support units are fixedly connected to the side of the end plate near the bottom of the slide rail base. Two symmetrically distributed adjustment grooves are opened on the top of the slide rail base. A slide seat unit is provided on the adjustment groove. Two sets of latches are opened on the top of the slide rail base and communicate with the adjustment groove. Each set of latches consists of several evenly distributed first positioning slots. A positioning pin is slidably connected in the adjustment groove.

[0014] Furthermore, the auxiliary support unit includes a bracket plate fixedly installed on one side of the end plate, a support arm fixedly installed on one side of the bracket plate, and the top of the support arm fitting against the bottom of the slide rail base; the adjustable slide groove is an I-shaped slide groove; the slide block unit includes an adjustable slider assembled in the adjustable slide groove and adapted to the adjustable slide groove, a sliding seat fixedly connected to the top of the adjustable slider, and a fixing plate slot opened on the top of the sliding seat; the positioning pin is fixedly connected by a sliding section, a first protruding section, a reset section and a second protruding section, and the top of the sliding section... Both sides of the sliding section are fixedly connected to a first protrusion section, the bottom of the sliding section is fixedly connected to a reset section, and the bottom edge of the reset section is fixedly connected to a second protrusion section. The height of the second protrusion section is the same as the movable distance of the reset section within the adjustable sliding groove, and the height of the second protrusion section is the same as the height of the first protrusion section. The first protrusion section is adapted to the first positioning slot. The bottom of the adjustable sliding groove is provided with several second positioning slots adapted to the second protrusion section, and the position of each second positioning slot corresponds to the position of the first positioning slot opened above it.

[0015] Furthermore, in this invention, the testing method of the long-distance fishing line tensile strength testing machine includes the following steps:

[0016] S1. Sample placement and positioning: First, install and fix the second fixing component, then straighten the fishing line to be tested along the axial direction of the end post and insert it into the slots of the two line holders to complete the axial placement of the fishing line.

[0017] S2. Winding and fixing: Wrap the axially placed fishing line around the outer wall of the end post 3-5 times in the circumferential direction, so that the fishing line to be tested is wound and pressed in the axial direction in sequence. At the same time, the fishing line presses the loosening plate during winding, and the loosening plate is compressed into the loosening groove.

[0018] S3. Line assembly: After one end of the fishing line is wrapped and fixed to the second fixing component, the fishing line is wrapped around the guide wheel and wrapped around the outer wall of the tail post multiple times. After wrapping around the tail post, it is fixed by hand pulling.

[0019] S4. Tensile test: The testing machine is started by pressing the control button. The ball screw inside the column drives the guide wheel to move at a constant speed. During the movement, the fishing line to be tested is subjected to tensile test. The fishing line tensile data is collected in real time until the fishing line breaks.

[0020] S5. Line loosening and unloading: After the fishing line breaks, the tension of the fishing line wrapped around the outer wall of the line loosening plate disappears instantly. The elastic strip releases its stored energy, causing the line loosening plate to pop out radially, which opens up the fishing line wrapped around the end post, making it easier for staff to clean up the waste line. The fishing line wrapped around the tail post can be removed by simply winding the fishing line in your hand.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention, by employing a second fixing component in conjunction with a first fixing component at the top of the column and a guide wheel reversing structure, can be adapted to the overall tensile strength test of fishing lines with a distance of 5 meters or more. It breaks through the limitations of traditional short-distance testing equipment, closely matches actual fishing conditions, and provides higher reference value for test data.

[0023] 2. The present invention is equipped with a second fixing component, which abandons the traditional rigid clamping structure and adopts the axial positioning of the rubber line holder and the self-friction winding fixing method of the fishing line. This will not squeeze or cut the fishing line, effectively avoid the problem of premature breakage of the fishing line clamping end, and greatly improve the testing accuracy.

[0024] 3. The present invention is equipped with a line loosening unit. After the fishing line breaks, the line loosening plate automatically pops out and opens the fishing line coil, eliminating the need for manual disassembly of each coil. This completely solves the problems of long-distance fishing line being too tightly wrapped and cumbersome unloading, and significantly improves detection efficiency. Attached Figure Description

[0041] Example 1

[0042] Please see Figures 1 to 4 This embodiment provides the following technical solution: a long-distance fishing line tensile strength testing machine, including a base 1, with a column 4 and a display device 2 fixedly connected to the top two sides of the base 1 respectively, a control button 3 provided on the top of the base 1, and a first fixing component 6 provided on the top of the column 4. The first fixing component 6 includes a mounting plate 61 fixedly connected to the top of the column 4, a tail line post 62 fixedly connected to one side of the mounting plate 61, and the tail line post 62 and the guide wheel 5 located in the same vertical plane; the guide wheel 5 is located on one side of the column 4 and is connected to a ball screw inside the column 4. The guide wheel 5 is used to drive the fishing line to be tested to perform tensile strength testing; and a second fixing component 7 is used to fix one end of the fishing line to be tested.

[0043] Specifically, the base 1 is the supporting body of the testing machine, made of metal plate. The display device is existing technology, used to display various data of the tensile test in real time for easy observation by staff. The control button 3 is used to start and stop the equipment. The column 4 is a vertical rigid support column, with an integrated ball screw transmission mechanism to achieve uniform vertical displacement of the guide wheel 5. The guide wheel 5 has a smooth arc groove with a polished surface, free of burrs and sharp edges, which plays the role of changing the direction of the fishing line and guiding the force. It does not clamp or wear the fishing line, and can smoothly transmit the tensile driving force to drive the long-distance fishing line to be tested to complete the tensile test.

[0044] Furthermore, the mounting plate 61 is a rigid metal plate, which is fixed to the top of the column 4 by bolts, ensuring a stable and wobbly installation. One side of the mounting plate 61 is vertically fixed to the tail post 62, which is a solid cylindrical structure with smooth protrusions on its surface. This allows the fishing line to obtain greater friction when winding, making it easier to wind and fix. At the same time, the tail post 62 has no sharp edges or burrs, preventing scratches on the fishing line when winding. The tail post 62 and the guide wheel 5 are located on the same vertical plane, ensuring that the fishing line is vertically aligned and there is no skewing or eccentric load during the stretching process, effectively improving the testing accuracy.

[0045] like Figures 2 to 4As shown, the second fixing component 7 includes a fixing plate 71 fixedly connected to the wall, an extension post 72 fixedly connected to the side of the fixing plate 71 near the testing machine, and an end line post 73 sleeved on the outer wall of the extension post 72; a loosening groove 732 with one end extending through the axial direction of the end line post 73 is opened on the outer wall of the end line post 73, and a connecting post 731 fixedly connected to the side of the end line post 73 near the end line post 73 through the loosening groove 732; it also includes a loosening unit 74 for quickly unloading the fishing line after it breaks during testing.

[0046] Furthermore, the fixing plate 71 is fixedly connected to the wall surface by expansion bolts. The fixing plate 71 must be strong in terms of fixing stability and be able to withstand the tensile load during the stretching process of the fishing line. The side of the fixing plate 71 closest to the testing machine is horizontally fixedly connected to the extension column 72. The extension column 72 is a rigid support column, which plays the role of extending support and widening the line routing space. The end post 73 is a detachable cylindrical winding base. The end post 73 has mounting holes on both ends of its surface. The end post 73 is fixed to the extension column 72 by bolts passing through the mounting holes. The end post 73 is the core component for the main winding and fixing of the fishing line. It is suitable for the winding and installation of long-distance fishing lines. The end post 73 can be replaced at any time according to the degree of wear during testing.

[0047] The loosening unit 74 includes a loosening plate 741 disposed on the loosening groove 732. The loosening plate 741 is adapted to the loosening groove 732. An elastic strip 742 is fixedly connected to one end of the loosening plate 741 near the connecting post 731. A connecting ring 743 is fixedly connected to one end of the elastic strip 742. The connecting ring 743 is sleeved and fixed to the outer wall of the connecting post 731.

[0048] Specifically, the line loosening unit 74 is a line loosening and unloading structure, which is used to automatically open the tightly wrapped fishing line coil after the fishing line breaks due to tension, so as to realize the quick disassembly of the waste line without the need for manual disassembly of each coil, which greatly improves the testing efficiency.

[0049] Furthermore, the outer wall of the end post 73 is provided with an axially penetrating loosening groove 732. The loosening groove 732 is a long, regular groove with smooth, burr-free walls. The groove size is precisely matched to the structure of the loosening plate 741 of the loosening unit 74. The connecting post 731 is a small cylindrical fixing base used to fix the elastic transmission structure of the elastic strip 742 on the loosening unit 74, providing a stable mounting point for the loosening unit 74. The loosening plate 741 is a long, plate-like structure, and its overall shape and size are perfectly matched to the loosening groove 732. It can be completely stored inside the loosening groove 732. After storage, it fits perfectly with the loosening plate 732. The outer surface of the end post 73 has a smooth transition without any protruding steps, which does not affect the normal winding and fixing of the fishing line. The elastic strip 742 is made of high-elasticity spring steel sheet material, which is fatigue-resistant, has stable elasticity, and reversible deformation. It can be repeatedly compressed to store energy and released to rebound, resulting in a long service life. The elastic strip 742 provides the radial ejection driving force for the slack plate 741. The connecting ring 743 is a metal ring structure that is sleeved and fixed to the outer wall of the connecting post 731. The sleeve is tight and there is no looseness, which realizes the stable assembly of the elastic strip 742 and the end post 73, ensuring that the elastic strip 742 does not shift or fall off during the deformation process.

[0050] like Figure 4 and Figure 5 As shown, both ends of the outer wall of the slack line plate 741 are fixedly connected to line holders 75. The line holders 75 are made of rubber. The top of the line holders 75 has a slot. The top of the slot is an open structure that unfolds outwards, and the bottom of the slot is a groove structure with a diameter smaller than that of the fishing line.

[0051] Specifically, the two line holders 75 are symmetrically arranged and work together to achieve precise axial positioning of the fishing line. The line holders 75 are made of flexible rubber material and are molded in one piece. They are soft, tough, wear-resistant and anti-aging, and will not cause squeezing damage to the fishing line. The top of the line holder 75 has a locking slot. The top of the locking slot is an open structure that opens outward, which makes it easy to press and lock the fishing line in quickly. It is easy to install and remove. The bottom of the locking slot is a narrow-diameter slot structure. The diameter of the slot is smaller than the diameter of the fishing line. After the fishing line is locked in, it can be stably limited and will not shift or slip during the winding process.

[0052] Example 2

[0053] The difference between this embodiment and Embodiment 1 is that: Figures 6 to 11As shown, it also includes an installation component. The installation component 8 includes an end plate 813 fixedly installed on the wall surface. A slide rail base 81 is fixedly installed on one side of the end plate 813. Two sets of auxiliary support units 84 are fixedly connected to the side of the end plate 813 near the bottom of the slide rail base 81. Two symmetrically distributed adjustable slide grooves 811 are opened on the top of the slide rail base 81. A slide seat unit 82 is provided on the adjustable slide groove 811. Two sets of latches are opened on the top of the slide rail base 81 and communicate with the adjustable slide grooves 811. Each set of latches consists of several sets of evenly distributed first positioning slots 812. A positioning pin 83 is slidably connected in the adjustable slide groove 811.

[0054] The auxiliary support unit 84 includes a bracket plate 841 fixedly installed on one side of the end plate 813. A support arm 842 is fixedly installed on one side of the bracket plate 841. The top of the support arm 842 is in contact with the bottom of the slide rail base 81. The adjustable slide groove 811 is an I-shaped slide groove. The slide block unit 82 includes an adjustable slider 823 assembled in the adjustable slide groove 811 and adapted to the adjustable slide groove 811. The top of the adjustable slider 823 is fixedly connected to the sliding block 821. The top of the sliding block 821 is provided with a fixing plate slot 822 adapted to the fixing plate 71.

[0055] The positioning pin 83 is formed by a sliding section 831, a first protruding section 832, a reset section 833, and a second protruding section 834 fixedly connected together. The first protruding section 832 is fixedly connected to both sides of the top of the sliding section 831, and the reset section 833 is fixedly connected to the bottom of the sliding section 831. The second protruding section 834 is fixedly connected to the bottom edge of the reset section 833. The height of the second protruding section 834 is consistent with the movable distance of the reset section 833 within the adjustable sliding groove 811, and the height of the second protruding section 834 is consistent with the height of the first protruding section 832. The first protruding section 832 is adapted to the first positioning slot 812. Several second positioning slots 814 adapted to the second protruding section 834 are opened at the bottom of the adjustable sliding groove 811. The position of each second positioning slot 814 corresponds to the position of the first positioning slot 812 opened above it.

[0056] Specifically, the mounting component 8 is used to detachably fix the second fixing component 7. By adjusting the different positions of the second fixing component 7 on the mounting component 8, the distance of the fishing line to be tested can be adjusted to achieve rapid adjustment. The end plate 813 is machined from steel sheet and fixed to the wall surface by bolt fasteners. One side of the end plate 813 is bolted to the end of the slide rail base 81 with a long strip profile structure. The slide rail base 81 is made of aluminum alloy extrusion molding and has high bending strength. Two sets of auxiliary support units 84 are symmetrically arranged near the bottom of the slide rail base 81. The bracket plate 841 of the auxiliary support unit 84 is fixedly installed on the end plate 813. The support arm 842 is a triangular reinforcing arm structure, which is used to support the slide rail base 81.

[0057] The adjustable slide 811 is an I-shaped slide 811 that runs through the entire length of the slide rail base 81. The interior of the adjustable slide 811 can accommodate the sliding of the sliding component. A slide seat unit 82 is configured on the adjustable slide 811. The adjustable slider 823 is housed inside the cavity of the adjustable slide 811. The two sides of the adjustable slide 811 are fastened with retaining edges to prevent the adjustable slider 823 from coming out. The top of the adjustable slider 823 is fastened to the slide seat 821. A fixing plate slot 822 is provided on the slide seat 821. The fixing plate slot 822 matches the fixing plate 71.

[0058] The top of the slide rail base 81 has two sets of slots communicating with the adjustable slide groove 811. Each set of slots consists of multiple sets of first positioning slots 812 evenly arranged along the length direction, with a spacing of 0.5m between any two adjacent first positioning slots 812. The bottom wall of the adjustable slide groove 811 also has several second positioning slots 814, which correspond one-to-one with the upper first positioning slots 812. The positioning pin 83 is slidably assembled inside the adjustable slide groove 811. The positioning pin 83 is integrally formed by a sliding section 831, a first protruding section 832, a reset section 833, and a second protruding section 834. The top two sides of component 1 are respectively provided with a first protrusion section 832, which can be engaged and matched with the first positioning slot 812; the lower end of the sliding section 831 is connected to the reset section 833, and the bottom edge of the reset section 833 is provided with a second protrusion section 834, which is adapted and engaged with the second positioning slot 814; the height of the second protrusion section 834 is equal to the movable stroke distance of the reset section 833 inside the adjustable sliding groove 811, and the height of the second protrusion section 834 is consistent with the height of the first protrusion section 832, so as to ensure that the first protrusion section 832 and the second protrusion section 834 can be simultaneously disengaged or simultaneously engaged in the corresponding slot.

[0059] Through the above technical solution, the long-stroke slide rail base 81 is installed on the wall by the end fixing plate 813. The symmetrically arranged auxiliary support unit 84 supports the slide rail base 81 from the bottom. The auxiliary support unit 84 offsets the bending and overturning load caused by the self-weight of the slide rail base 81 and the tension of the fishing line, reduces the deflection deformation of the long-distance slide rail, and ensures the shape and position accuracy of the slide rail base 81. The slide unit 82 slides linearly along the I-shaped adjustment groove 811 by the adjustment slider 823, thereby changing the installation position of the slide unit 82. The distance between every two adjacent first positioning slots 812 is 0.5m, which can adjust the effective test length of the fishing line to be tested on the second fixing component 7 at any time.

[0060] The positioning pin 83 acts as a portable latch to limit the displacement of the slide unit 82. Specifically, when the positioning pin 83 is pulled upwards, the first protrusion 832 and the second protrusion 834 are released from their corresponding first positioning slots 812 and 814, allowing the slide unit 82 to move along the adjustable sliding groove 811. When moving to the next set of first positioning slots 812 and 814, pressing the positioning pin 83 re-engages the first protrusion 832 and the second protrusion 834, achieving bidirectional synchronous locking and preventing the slide unit 82 from slipping or tilting during testing. The adjustable sliding groove 811 and the adjustable slider 823 form a locking sliding pair. The main tensile load generated by the fishing line test is borne by the profile slide rail base 81, while the positioning pin 83 only serves as a stop, improving the overall reliability of the mechanism and meeting the requirements for long-distance fishing line tensile testing.

[0061] The testing method of the long-distance fishing line tensile strength testing machine of the present invention includes the following steps:

[0062] S1. Sample placement: First, install and fix the second fixing component 7, then straighten the fishing line to be tested along the axial direction of the end post 73, press and insert it from the opening at the top of the line holder 75, so that the fishing line is inserted into the bottom slot to complete the limiting and fixing. By inserting it into the slots of the two line holders 75, the axial displacement of the fishing line is completed, ensuring that the subsequent winding is neat.

[0063] S2. Winding and fixing: The axially placed fishing line is wound around the outer wall of the end post 73 3-5 times in a circumferential direction, so that the fishing line to be tested is wound and pressed in a sequential manner along the axial direction. The circumferentially wound fishing lines do not misalign with each other. The friction between the circumferentially wound fishing line and the axial fishing line is used to achieve clamp-free anti-slip fixing. At the same time, the fishing line presses the loosening plate 741 during winding, compressing the loosening plate 741 into the loosening groove 732. The elastic strip 742 stores elastic potential energy when compressing the loosening plate 741, thus completing the initial fixing of the fishing line before testing.

[0064] S3. Line assembly: After one end of the fishing line is wrapped and fixed to the second fixing component 7, the middle section of the fishing line is passed upwards around the guide wheel 5, and then the end of the fishing line is wrapped around the outer wall of the tail post 62 multiple times. After being wrapped around the tail post 62, the fishing line is held and pulled to fix it, ensuring that the entire long fishing line is straight, without slack or twisting, and does not need to be cut or fixed. If the fishing line breaks, the part of the fishing line wrapped on the tail post 62 can be rewound into the fishing line.

[0065] S4. Tensile test: The testing machine is started by pressing the control button 3. The ball screw inside the column 4 drives the guide wheel 5 to move at a constant speed. During the movement, the fishing line to be tested is subjected to tensile test. The fishing line tensile data is collected in real time until the fishing line breaks, and the tensile test is completed.

[0066] S5. Line loosening and unloading: After the fishing line breaks, the tension of the fishing line wrapped around the outer wall of the line loosening plate 741 disappears instantly. The elastic strip 742 releases its stored energy, causing the line loosening plate 741 to pop out radially, which opens up the fishing line wrapped around the end post 73, making it convenient for staff to clean up the waste line. The fishing line wrapped around the tail post 62 can be removed by simply winding the fishing line in hand, making unloading convenient and efficient.

[0067] The working principle of the technical solution provided by the present invention is as follows: one end of the fishing line to be tested is pulled out and straightened along the axial direction of the end post 73. It is then pressed and inserted into the opening at the top of the line holder 75, so that the fishing line is inserted into the bottom slot to complete the limiting and fixing. By inserting it into the slots of the two line holders 75, the axial placement of the fishing line is completed without deviation.

[0068] Wrap the axially positioned fishing line coil around the outer wall of the end post 73 3-5 times in a circumferential direction. This ensures that the fishing line to be tested is wrapped and pressed tightly along the axial direction, preventing misalignment between the circumferentially wrapped lines. Simultaneously, the fishing line presses against the loosening plate 741 during wrapping, compressing the loosening plate 741 into the loosening groove 732. This completes the initial fixation of the fishing line before testing. After one end of the fishing line coil is wrapped and fixed to the second fixing component 7, the middle section of the fishing line in the coil is passed upwards over the guide wheel 5. Then, the end of the fishing line is wrapped multiple times around the outer wall of the tail post 62. After wrapping around the tail post 62, the fishing line coil is held and pulled to fix it.

[0069] Next, press control button 3 to start the testing machine. The ball screw inside column 4 drives guide wheel 5 to move at a constant speed. During the movement, it drives the fishing line to be tested to perform a tensile test and collects the fishing line tension data in real time until the fishing line breaks, completing the tensile test. The test data can be viewed through display device 2. After the fishing line breaks, the clamping force of the fishing line wrapped on the outer wall of the loosening plate 741 disappears instantly. The elastic strip 742 releases the stored energy and drives the loosening plate 741 to pop out radially, opening the fishing line wrapped on the end post 73. The staff only needs to manually peel off the fishing line wrapped on the end post 73. Finally, the fishing line stuck on the line holder 75 can be pulled out. At the same time, the fishing line wrapped on the tail post 62 can be removed by simply winding the fishing line in hand. The unloading is convenient and efficient.
