Description

A fiber optic stripper and its usage method Technical Field

[0001] This invention relates to the field of tool technology, and in particular to a fiber optic stripper and its method of use. Background Technology

[0002] Fiber optic transmission is widely used in communication systems. Fiber optic cables are usually connected to each other through fiber optic connectors. When connecting fiber optic cables, the end faces of the cables are usually required to be flat to ensure that the optical signal can be transmitted from one fiber optic cable to another efficiently and without loss.

[0003] In related technologies, such as Chinese Patent (Publication No. CN219997340U), a fiber optic cable processing tool is disclosed, which includes a box-shaped base and integrates functions such as stripping the outer layer of the fiber optic cable, stripping the coating layer, cleaning the fiber optic cable, and cutting the fiber optic cable. However, when using this fiber optic cable processing tool, the base needs to be placed on a platform to operate and achieve the above functions. This means that the base is difficult to hold and use with one hand, which limits its use in scenarios such as high-altitude operations and operations in confined spaces. In addition, the base has two layers, each with different functional areas, and the corresponding functions are operated through different operating parts (for example, by operating the stripping blade to open and close relative to the stripping fixing seat to remove the cable sheath and rigid reinforcing members such as copper wire and iron wire; by operating the first base cover to open and close relative to the first base body to clean and cut the fiber optic cable), which is also quite cumbersome to operate.

[0004] It can be seen that although existing fiber optic strippers can strip optical fibers into bare fibers and shape the end faces of the bare fibers, existing fiber optic strippers are difficult to operate with one hand to complete the stripping and end face shaping. They are cumbersome to operate and have low efficiency, and need to be improved.

[0005] Summary of the Invention

[0006] The purpose of this invention is to address the problems of existing fiber optic strippers being difficult to operate with one hand to strip optical fibers into bare fibers and shape the end faces of the bare fibers, resulting in cumbersome operation and low efficiency. This invention provides a fiber optic stripper and its usage method.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A fiber optic stripper includes a first handle, a second handle, a hinge, and a fiber optic stripper head. The fiber optic stripper also includes:

[0009] The third handle is mounted on either the first or second handle.

[0010] An optical fiber end-facer is mounted on a first handle or a second handle. The optical fiber end-facer includes a body, a cap, and a cutting assembly installed inside the optical fiber end-facer.

[0011] The movement of the third handle can drive the pressure cap to move toward the main body until it closes, and can also enable the cutting assembly to move to complete the end face forming of the optical fiber.

[0012] The fiber optic stripper described in this invention integrates the fiber end-face shaper onto the stripper. The first and second handles, via the hinge, control the opening and closing of the stripper head. The third handle controls the operation of the fiber end-face shaper. The three handles are positioned close together, allowing for single-handed operation of both the stripper head and the fiber end-face shaper. This means that the fiber processing and bare fiber end-face shaping functions can be completed with a single hand operation of the first, second, and third handles. This eliminates the need to switch between different tools or adjust the functionality of the tools, offering high flexibility and promising application prospects.

[0013] In a preferred embodiment of the present invention, the third handle drives the pressure cap and the cutting assembly to move via a transmission component. In some embodiments, the first handle, the second handle, and the third handle are all hinged to the hinge portion.

[0014] This structure optimizes the fiber optic stripper, making it more compact and facilitating one-handed operation of the first handle, second handle, and third handle.

[0015] As a preferred embodiment of the present invention, the first elastic reset member is a spring or a torsion spring.

[0016] As a preferred embodiment of the present invention, the third handle is located on the same side as the second handle.

[0017] This structure allows the operator to use the first handle as the primary gripping object and select to operate the second or third handle to make the fiber optic stripper head or the fiber optic end face shaper work.

[0018] As a preferred embodiment of the present invention, an adjustment device is provided between the fiber end-face shaper and the first handle to adjust their relative positions. This allows the handle and end-face shaper to be processed separately, reducing the difficulty of assembling them.

[0019] As a preferred embodiment of the present invention, the rotation axis between the first handle and the second handle is parallel to the rotation axis between the first handle and the third handle.

[0020] This structure is advantageous because of the human hand's structure; the thumb has a larger span relative to the other four fingers. If all the rotation planes are basically parallel to the palm, this arrangement facilitates the single-handed operation of the first, second, and third handles.

[0021] As a preferred embodiment of the present invention, there is an angle between the rotation axes of the first handle and the second handle and the rotation axes of the first handle and the third handle.

[0022] With this structure, the flexibility of the fingers and palm is utilized. The fingers hold the first and second handles to control the opening and closing of the fiber optic stripper head, while the palm supports or releases the third handle to rotate relative to the first handle, thereby controlling the opening and closing of the fiber optic end face shaper.

[0023] As a preferred technical solution of the present invention, the optical fiber end face shaper includes two opening and closing components, one of which is the first handle and the other is a pressure cap.

[0024] This structure integrates the main body of the fiber end-face shaper with the first handle, significantly reducing the overall size of the fiber stripper. The structure has a reasonable center of gravity, making it more convenient for the operator to use and facilitating one-handed operation.

[0025] As a further preferred technical solution of the present invention, the transmission component includes a transmission rod system, or includes a transmission rod system and a gear rack.

[0026] As a further preferred technical solution of the present invention, the transmission component includes a first rod, a second rod, and a third rod; the first rod is disposed between the first handle and the third handle, and one end of the first rod is hinged to the first handle; both ends of the second rod are respectively hinged to the pressure cap and the other end of the first rod; both ends of the third rod are respectively hinged to the third handle and the first rod.

[0027] This structure connects the first handle, the third handle, and the fiber end-face shaper via a transmission rod system (i.e., a linkage mechanism), making the position and opening orientation of the fiber end-face shaper more flexible. The transmission rod system has a large adjustment range, is easy to replace, and has a compact structure, making it the recommended solution.

[0028] As a preferred embodiment of the present invention, the transmission component includes a slider, a first rod, and a second rod; the third handle is provided with a strip groove, the length direction of which is arranged along the length direction of the third handle, and the slider is slidably connected in the strip groove; the first rod is disposed between the first handle and the third handle, and the two ends of the first rod are respectively hinged to the first handle and the slider; the two ends of the second rod are respectively hinged to the slider and the pressure cap.

[0029] With this structure, the force of the first handle and the third handle is transmitted to the fiber end face shaper through the linkage mechanism and the slider mechanism. This also makes the position, opening orientation and other settings of the fiber end face shaper more flexible.

[0030] As a preferred embodiment of the present invention, the transmission component includes a fourth rod, a rack, and a gear; one end of the fourth rod is hinged to the third handle; the first handle is provided with a slide rail, the rack is slidably connected to the slide rail, and one end of the rack is hinged to the other end of the fourth rod; the gear is provided on the first handle, the gear meshes with the rack, and the gear drives the pressure cap to move.

[0031] With this structure, the force of the first handle and the third handle is transmitted to the fiber end face shaper through the linkage mechanism and the gear rack mechanism. This also makes the position, opening orientation and other settings of the fiber end face shaper more flexible.

[0032] As a preferred technical solution of the present invention, the pressure cap is rotatably connected to the first handle, and the first elastic reset member is provided at the pivot, which can drive the pressure cap to reset.

[0033] With this structure, the cover adopts a rotating and normally open design. The normally open design allows for direct use of the fiber end face shaper, while the rotating design greatly simplifies the transmission system of the cover, reducing the failure rate. Furthermore, the cover can be reset by the first elastic reset element located at the pivot. After use and closure, there is no need for manual adjustment of the cover to open, which is beneficial for improving work efficiency and ease of use.

[0034] As a preferred embodiment of the present invention, the fiber end-face shaper further includes a length-fixing platform, a clamping assembly, a cutting assembly, and a striking assembly; the length-fixing platform is connected to the side of the first handle, and the length-fixing platform extends the bare fiber into the fiber end-face shaper; the clamping assembly is disposed on the fiber end-face shaper, and the clamping assembly is used to clamp the bare fiber after the fiber end-face shaper is closed; the cutting assembly is disposed inside the main body, and the cutting assembly is used to scribing and cutting the bottom of the clamped bare fiber; the striking assembly is disposed on the pressure cap, and the striking assembly is used to break the cut bare fiber by striking.

[0035] With this structure, the length of the bare fiber end face after forming can be determined by the fixed-length platform. The end face forming of the bare fiber is completed by the clamping and fixing by the clamping component, the scribing and cutting by the cutting component, and the hammering and breaking by the hammering component. This method utilizes the brittleness of optical fiber and stress fracture forming.

[0036] As a further preferred technical solution of the present invention, the clamping assembly includes a first clamping pad and a second clamping pad; the first clamping pad is connected to the pressure cap; the second clamping pad is connected to the main body, and after the fiber end face shaper is closed, the first clamping pad and the second clamping pad cooperate to clamp the bare fiber.

[0037] With this structure, the bare fiber is effectively clamped from both top and bottom directions by the first clamping pad and the second clamping pad, preventing the bare fiber from sliding or detaching.

[0038] As a further preferred technical solution of the present invention, the cutting assembly includes a sliding block, a cutter, a protrusion, an unlocking member, and a reset rod; the sliding block is slidable along the length direction of the first handle, and the end face of the sliding block is connected to the first handle through a first elastic member, which moves the sliding block toward the side of the cap pivot; the cutter is connected to the sliding block, and the cutting trajectory of the cutter is perpendicular to the length direction of the bare fiber; the protrusion is connected to the sliding block, and the top surface of the protrusion is lower than the top of the cutter; the unlocking member is disposed on the first handle, and the unlocking member is used to lock the sliding block; when the clamping assembly clamps the bare fiber, the unlocking member unlocks the sliding block; the reset rod is connected to the cap, and when the first elastic reset member drives the cap to reset, the reset rod pushes the sliding block to reset.

[0039] With this structure, the unlocking component forms a switch for unlocking and locking the sliding block. The cover, in conjunction with the unlocking component, unlocks the sliding block. The reset rod pushes the sliding block back to its original position and, in conjunction with the unlocking component, relocks the sliding block. The cover drives the clamping assembly and the reset rod to work together. The sliding block drives the cutter and the protrusion to work together. The cutter then scribing and cutting the bare fiber. In other words, the cutting assembly forms a clever structure with interconnected functional zones, capable of performing corresponding functions and resetting.

[0040] As a further preferred technical solution of the present invention, the unlocking component includes an unlocking rod and a second elastic reset component; the unlocking rod is disposed inside the first handle, the lower side of the unlocking rod is provided with a hook, the top end of the unlocking rod extends out of the mating surface between the first handle and the pressure cap, the sliding block is provided with a groove, the hook engages in the groove, when the clamping assembly clamps the bare fiber, the pressure cap presses the unlocking rod, and the hook disengages from the groove; the second elastic reset component is disposed inside the first handle, the second elastic reset component is connected to the unlocking rod, and the second elastic reset component is used to reset the unlocking rod.

[0041] With this structure, the unlocking rod acts as the switch for the sliding block to control the pressure cover, and the second elastic reset member acts as the reset member for the unlocking rod. In other words, the unlocking rod cleverly serves as the linkage between the pressure cover and the sliding block.

[0042] As a further preferred technical solution of the present invention, the striking assembly includes a hammer and a second elastic element; the hammer is slidably connected to the bottom of the pressure cover, and the hammer is used to strike the bare fiber; after the fiber end face shaper is closed, the hammer abuts against the protrusion; the second elastic element is disposed inside the pressure cover, and the second elastic element is used to eject the hammer from the pressure cover; when the unlocking member unlocks the sliding block, the protrusion moves with the sliding block and disengages from the hammer, and the hammer ejects to strike the bare fiber.

[0043] With this structure, the bare fiber is stress-broken by striking and bending it with a hammer. The hammer is controlled by the protrusion to limit its contact with the bare fiber and is driven by the second elastic element, which can form a linkage with the pressure cap.

[0044] As a further preferred technical solution of the present invention, the first handle is provided with a first cavity, the sliding block, the first elastic element, the cutter and the protrusion in the main body are disposed in the first cavity, and the reset rod extends into the first cavity.

[0045] As mentioned above, the fiber end-face shaper and the first handle are integrated into a design. With this structure, the first handle is further used as a mounting platform for part of the cutting components, so that the fiber end-face shaper and the fiber stripper are organically combined, seamlessly integrating different functional modules, improving the overall performance of the fiber stripper, and making the positions of the fiber stripper head and the fiber end-face shaper closer, which is more convenient to use. The design of the first cavity also reduces the weight of the first handle, which is conducive to one-handed operation of the fiber stripper.

[0046] As a further preferred technical solution of the present invention, the fiber optic stripper is provided with a locking component, which is used to close the pressure cap.

[0047] This structure reduces the opening and closing angle of the cover, minimizes space occupation, and facilitates the packaging and transportation of the fiber optic stripper.

[0048] As a preferred embodiment of the present invention, the second handle is provided with a second cavity, and the third handle passes through the second cavity and penetrates the second handle.

[0049] With this structure, the second cavity serves as the channel for the third handle, and the operating direction of the third handle is the same as that of the second handle. This makes the fiber optic stripper as compact and small as possible, saving space and facilitating one-handed operation.

[0050] Secondly, the present invention also provides a method of using fiber optic strippers as described in any of the above claims, comprising holding the first handle and the second handle, processing the fiber optic cable into a bare fiber using the fiber optic stripper head; holding the first handle and the third handle, and flattening the end face of the bare fiber using the fiber end face shaper.

[0051] The fiber optic stripper described in this invention integrates a fiber optic stripper head and a fiber optic end-face shaper into a single tool. This allows the tool to process the fiber optic cable into a bare fiber using the stripper, and then shape the bare fiber end face using the end-face shaper. Furthermore, this tool allows for single-handed operation of the first handle, the second handle, and the third handle to perform both fiber processing and bare fiber end-face shaping. It eliminates the need to switch between different tools or adjust the functionality of the tool's components, offering high flexibility and excellent performance.

[0052] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0053] The fiber optic stripper of this invention integrates the fiber end-face shaper onto the stripper itself. Operating the first and second handles controls the opening and closing of the stripper head to strip the fiber sheath. Then, by holding the first and second handles and operating the third handle with fingers, the fiber end-face shaper is opened and closed, and the internal cutting components move to shape the bare fiber end face. The fiber optic stripper of this invention allows for single-handed operation of all three handles, enabling direct use of both the stripper head and the fiber end-face shaper. That is, the fiber processing and bare fiber end-face shaping functions can be completed by operating the first, second, and third handles with one hand, without needing to switch between different tools or even adjust the state of the tool's functional parts. This high flexibility offers promising application prospects.

[0054] The present invention relates to a method for using fiber optic strippers. By integrating a fiber optic stripper head and a fiber optic end-face shaper into a single pair of pliers, this tool enables the stripper to process fiber optics into bare fibers, and then the fiber optic end-face shaper to shape the bare fibers. Furthermore, this tool allows for single-handed operation of the first handle, the second handle, and the third handle to perform both fiber processing and bare fiber end-face shaping functions. It eliminates the need to switch between different tools or adjust the functionality of the tools, offering high flexibility and excellent results. Attached Figure Description

Detailed Implementation

[0077] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0078] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0079] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0080] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0081] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, nine, or even more than nine.

[0082] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0083] In related technologies, existing fiber optic strippers can strip optical fibers into bare fibers and shape the end faces of the bare fibers. However, existing fiber optic strippers are difficult to operate with one hand to complete stripping and end face shaping, resulting in cumbersome operation and low efficiency, requiring improvement. Therefore, the technical solution of this application was developed, and will be described below with reference to Figures 1 to 21.

[0084] Example 1

[0085] As shown in Figures 1 to 21, the fiber optic stripper of the present invention includes the fiber optic stripper of the prior art. The fiber optic stripper includes a first handle 11, a second handle 12, a hinge part 13, and a fiber optic stripper head 14. The fiber optic stripper head 14 is used to strip the fiber optic jacket and / or clean the light. The fiber optic stripper head 14 can be opened and closed by rotating the first handle 11 and the second handle 12 around the hinge part 13.

[0086] Based on the fiber optic stripper, the fiber optic stripper also includes a third handle 21, a transmission component, and a fiber end face shaper 22.

[0087] The fiber optic stripper can refer to all the contents of a multi-functional fiber optic stripper disclosed in Chinese Patent (Publication No. CN218767397U), which is also called an 8-in-1 fiber optic stripper. The present embodiment adds the fiber end face shaper 22 to this, which can be used for fiber end face shaping, thus adding an extra function. Therefore, the present embodiment can be called a 9-in-1 fiber optic stripper.

[0088] The third handle 21 is hinged to the first handle 11, with the hinge point close to the hinge portion 13. The transmission component connects the first handle 11 and the third handle 21. The fiber end-face shaper 22 is mounted on the first handle 11, and the transmission component connects to the fiber end-face shaper 22. The fiber end-face shaper 22 includes a main body 2204 integrally formed with the first handle 11 and a pressure cap 2201. A first elastic reset member 23 is provided on the main body 2204. The fiber end-face shaper 22 is used for end-face shaping of bare fibers. In other embodiments, the main body 2204 and the handle can be processed separately and then assembled. An adjusting bolt can be added between the handle and the main body 2204 to adjust the relative position between the main body 2204 and the handle, thereby reducing the processing difficulty of each component.

[0089] The fiber end face shaper 22 is configured to be normally open. When the first handle 11 and the third handle 21 are rotated close together, the fiber end face shaper 22 can be driven to close through the transmission component. The first elastic reset member 23 is used to reset the fiber end face shaper 22 to open.

[0090] As an example, the first handle 11, the second handle 12 and the third handle 21 are all hinged to the hinge portion 13, that is, the hinge point of the third handle 21 and the first handle 11 coincides with the hinge portion 13; this can optimize the structure of the fiber optic stripper to be more compact and facilitate the operation of the first handle 11, the second handle 12 and the third handle 21 with one hand.

[0091] In one optional embodiment, the first elastic reset element 23 is a spring or a torsion spring. If the fiber end-face shaper 22 adopts a hinged opening and closing method, a torsion spring can be sleeved at the hinged pivot to achieve the reset of the fiber end-face shaper 22; alternatively, a spring can be provided near the pivot, with its two ends connected to the inner sides of the two opening and closing elements respectively, forming an elastic reset. If the fiber end-face shaper 22 adopts a vise-like opening and closing method, a spring can be provided between the two opening and closing elements to form an elastic reset.

[0092] In an optional implementation, as shown in Figures 1 to 21, the third handle 21 is located on the same side as the second handle 12. This allows the operator to use the first handle 11 as the primary gripping object and select to operate either the second handle 12 or the third handle 21 to make the fiber optic stripper head 14 or the fiber optic end-face shaper 22 work. For example, the first handle 11 is held by the operator in the web between the thumb and forefinger and extends to the palm. The second handle 12 or the third handle 21 is easily gripped by the fingers other than the thumb. Specifically, the third handle 21 is hooked by the forefinger, and the second handle 12 is hooked by the other three fingers, forming a good grip and control method. Of course, the third handle 21 can also be hooked by the forefinger and middle finger, and the second handle 12 can be hooked by the other two fingers. Even the second handle 12 can be hooked by the little finger, and the third handle 21 can be hooked by the other three fingers.

[0093] In one optional embodiment, the plane of rotation between the first handle 11 and the second handle 12 is parallel to the plane of rotation between the first handle 11 and the third handle 21. Because of the structure of the human hand, the thumb can have a relatively large span relative to the other four fingers. If all the planes of rotation are substantially parallel to the palm, this arrangement facilitates single-handed operation of the first handle 11, the second handle 12, and the third handle 21. Of course, in some other embodiments, it is also permissible for the two planes of rotation of the fiber optic stripper to have an angle, meaning the planes of rotation of the first handle 11 and the second handle 12 are not parallel to the planes of rotation of the first handle 11 and the third handle 21, yet the human hand can still effectively operate the fiber optic stripper.

[0094] The fiber end face shaper 22 includes two opening and closing components. The two opening and closing components can be hinged to form an opening and closing form like the fiber stripper head 14. The two opening and closing components can also be in an opening and closing form where they move closer to each other to close and move further apart to open. In some specific embodiments, this opening and closing form may require a guide rail to help one of the opening and closing components move closer to the other to avoid misalignment between the two opening and closing components.

[0095] As an example, as shown in Figures 1 to 7, the fiber end face shaper 22 includes two opening and closing components, one of which is the first handle 11 and the other is the pressure cap 2201. The advantage of this arrangement is that by incorporating part of the fiber end face shaper into the first handle 11, the structure of the fiber stripper can be made compact, smaller, and easier to use.

[0096] As an example, the transmission component includes a transmission rod system, as shown in Figures 6 and 7. The transmission component includes a first rod 31, a second rod 32, and a third rod 33. The first rod 31 is disposed between the first handle 11 and the third handle 21, with one end of the first rod 31 hinged to the first handle 11. The two ends of the second rod 32 are respectively hinged to the pressure cap 2201 and the other end of the first rod 31. The two ends of the third rod 33 are respectively hinged to the third handle 21 and the first rod 31. As those skilled in the art will understand, the third rod 33 obviously cannot be hinged at the hinge point between the first rod 31 and the first handle 11. In addition, according to the description in Embodiment 1, the transmission component can realize the rotational opening and closing of the pressure cap 2201 relative to the first handle 11, or the opening and closing of the pressure cap 2201 along the guide rail towards or away from the first handle 11. The first rod 31 is longer than the third rod 33 and both are straight rods, while the second rod 32 is a bent rod with the bending direction facing the pressure cap 2201.

[0097] In an optional embodiment, the transmission component includes a transmission rod system (not shown in the figure), the transmission component includes a slider, a first rod 31 and a second rod 32; the third handle 21 is provided with a strip groove, the length direction of the strip groove is arranged along the length direction of the third handle 21, and the slider is slidably connected in the strip groove; the first rod 31 is disposed between the first handle 11 and the third handle 21, and the two ends of the first rod 31 are respectively hinged to the first handle 11 and the slider; the two ends of the second rod 32 are respectively hinged to the slider and the pressure cap 2201. In addition, according to the description in Embodiment 1, the transmission component can realize the opening and closing of the pressure cap 2201 relative to the first handle 11, or realize the opening and closing of the pressure cap 2201 along the guide rail towards or away from the first handle 11.

[0098] In one optional embodiment, the transmission component includes a transmission rod system and a gear and rack system. Not shown, the transmission component includes a fourth rod, a rack, and a gear. One end of the fourth rod is hinged to the third handle 21. The first handle 11 is provided with a slide rail, and the rack is slidably connected to the slide rail. One end of the rack is hinged to the other end of the fourth rod. The gear is disposed on the first handle 11, meshes with the rack, and drives the pressure cap 2201 to move. Alternatively, additional gears and / or racks can be added to the aforementioned gear and rack for transmission. Furthermore, according to Embodiment 1, the transmission component can enable the pressure cap 2201 to rotate and open relative to the first handle 11, or enable the pressure cap 2201 to open and close along the guide rail towards or away from the first handle 11.

[0099] As an example, as shown in Figures 6 and 7, the tail of the pressure cap 2201 is connected to an arm 2202, and the aforementioned transmission component is ultimately connected to the arm 2202.

[0100] In an optional embodiment, as shown in Figures 1 to 7, the pressure cap 2201 is rotatably connected to the first handle 11, and the first elastic reset member 23 is disposed at the pivot. The fiber end-face shaper is configured to be normally open. As an example, the first elastic reset member 23 can be a torsion spring, specifically sleeved on the pivot of the pressure cap 2201. The pressure cap 2201 is normally open; when the pressure cap 2201 rotates closer to the first handle 11, the torsion spring stores force and generates a reset force on the pressure cap 2201. Alternatively, not shown, the first elastic reset member 23 can also be a spring, disposed near the pivot of the pressure cap 2201. The two ends of the spring are connected to the pressure cap 2201 and the first handle 11, respectively. When the pressure cap 2201 rotates closer to the first handle 11, the spring is compressed and stores force, generating a reset force on the pressure cap 2201.

[0101] As an example, as shown in Figures 1 to 10, the fiber end-face shaper further includes a length-fixing platform 2203, a clamping assembly, a cutting assembly, and a striking assembly; the length-fixing platform 2203 is connected to the side of the first handle 11, and the length-fixing platform 2203 extends the bare fiber into the fiber end-face shaper; the clamping assembly is disposed on the fiber end-face shaper, and the clamping assembly is used to clamp the bare fiber after the fiber end-face shaper is closed; the cutting assembly is disposed on the first handle 11, and the cutting assembly is used to scribing and cutting the bottom of the clamped bare fiber; the striking assembly is disposed on the pressure cap 2201, and the striking assembly is used to break the cut bare fiber by striking.

[0102] In an optional implementation, as shown in Figure 10, the fixed-length platform 2203 is provided with a drop fiber slot and a pigtail slot, and the drop fiber slot and the pigtail slot are arranged in a concentric slot body. The width of the drop fiber slot is greater than the width of the pigtail slot, and the depth of the pigtail slot is greater than the depth of the drop fiber slot. The center line of the concentric slot body is the position of the bare fiber in the drop fiber or pigtail.

[0103] In an optional embodiment, as shown in FIG10, a baffle is provided on the side of the length-fixing platform 2203 facing the first handle 11. The baffle is located at the end of the concentric groove and has a bare fiber groove. The center line of the bare fiber groove coincides with the center line of the concentric groove. When the drop fiber or pigtail falls into the concentric groove, the bare fiber matches and falls into the bare fiber groove, thus extending into the fiber end-face shaper through the bare fiber groove. A V-shaped groove is also provided on the baffle. The bottom of the V-shaped groove is connected to the bare fiber groove. The V-shaped groove allows the bare fiber to be quickly guided into the bare fiber groove, while the outer end of the drop fiber or pigtail abuts against the baffle, completing the positioning of the fiber to be cut. By setting different thicknesses of the baffle, the length from the bare fiber's exposure point to the cutting assembly can be controlled. Therefore, the length-fixing platform 2203 also has the function of determining the length of the bare fiber after cutting.

[0104] As an example, as shown in Figure 10, the bottom end of the bare fiber groove is flush with the clamping bottom surface of the clamping assembly. That is to say, the clamping assembly directly clamps and fixes the bare fiber extending from the bare fiber groove, forming a complete set of bare fiber length fixing components.

[0105] In an optional embodiment, the clamping assembly includes a first clamping pad 2211 and a second clamping pad 2212; the first clamping pad 2211 is connected to the pressure cap 2201; the second clamping pad 2212 is connected to the first handle 11, and after the fiber end face shaper is closed, the first clamping pad 2211 and the second clamping pad 2212 cooperate to clamp the bare fiber.

[0106] As an example, the first clamping pad 2211 and the second clamping pad 2212 can be rubber pads. The rubber pads have high friction with the bare fiber, which can effectively clamp and fix the bare fiber. At the same time, the rubber pads have a certain degree of elasticity, which can prevent the bare fiber from being clamped and broken.

[0107] In one optional embodiment, as shown in FIG10, the first clamping pad 2211 is detachably connected to the pressure cover 2201, and the second clamping pad 2212 is detachably connected to the first handle 11. When the rubber pads used age, the first clamping pad 2211 and the second clamping pad 2212 can be replaced by detachable connection. As an example, the first clamping pad 2211 is connected to the pressure cover 2201 by screws, and the second clamping pad 2212 is connected to the first handle 11 by screws. Alternatively, the first clamping pad 2211 and the second clamping pad 2212 are connected to the corresponding structure by snap-fit.

[0108] As an example, as shown in Figure 10, a second clamping pad 2212 is provided on each side of the first handle 11 in the direction of movement of the cutting component, that is, a total of two second clamping pads 2212 are provided. In contrast, two first clamping pads 2211 corresponding to the second clamping pads 2212 are provided on the pressure cover 2201 to provide a better clamping method, that is, bidirectional clamping on both sides of the cutting component, which is beneficial to the stability of the cutting component in cutting bare fibers, and to avoid the bare fibers falling off after breakage and forming glass shards, which could cause safety hazards.

[0109] As an example, as shown in Figures 6, 7, 9, and 10, the cutting assembly includes a sliding block 2221, a cutter 2222, a protrusion 2223, an unlocking member 2224, and a reset rod 2225. The sliding block 2221 is slidably connected to the side of the first handle 11 and can slide along the length of the first handle 11. The end face of the sliding block 2221 is connected to the first handle 11 through a first elastic member, which moves the sliding block 2221 toward the rotating shaft of the pressure cover 2201. The cutter 2222 is connected to the sliding block 2221, and the cutting of the cutter 2222... The trajectory direction is perpendicular to the length direction of the bare fiber; the protrusion 2223 is connected to the sliding block 2221, and the top surface of the protrusion 2223 is lower than the top of the cutter 2222; the unlocking member 2224 is provided on the first handle 11, and the unlocking member 2224 is used to lock the sliding block 2221. When the clamping assembly clamps the bare fiber, the unlocking member 2224 unlocks the sliding block 2221; the reset rod 2225 is connected to the pressure cap 2201. When the first elastic reset member 23 drives the pressure cap 2201 to reset, the reset rod 2225 pushes the sliding block 2221 to reset.

[0110] As an example, referring to the coordinate system shown in FIG7, the fiber optic stripper head 14 is considered as the front, the tail end of the first handle 11 as the rear, the relative positions of the first handle 11 and the second handle 12 as the top and bottom respectively, the left hand position when facing the front is considered as the left side, and the right hand position as the right side. The first elastic element, which is a tension spring, is connected to the front end face of the sliding block 2221. The sliding block 2221 is initially located behind the first handle 11. When the unlocking member 2224 unlocks the sliding block 2221, under the tension of the tension spring, the sliding block 2221 moves towards the front of the first handle 11. During this movement, the cutter 2222 completes the bare fiber cutting and scribing. Of course, the tension spring can be replaced with a rubber band, piston, or other components that can provide tension.

[0111] In an optional embodiment, the first elastic element is connected to the rear end face of the sliding block 2221. The first elastic element is a compression spring. The sliding block 2221 is initially located on one side behind the first handle 11. When the unlocking member 2224 unlocks the sliding block 2221, the sliding block 2221 moves towards the front side of the first handle 11 under the thrust of the compression spring. During the movement, the cutter 2222 completes the bare fiber cutting and scribing. Of course, the above-mentioned compression spring can be replaced by a folding spring, rubber block, piston, elastic metal sheet, or other components that can provide thrust.

[0112] As an example, the reset rod 2225 is a curved rod, as shown in Figures 6 and 7. The end of the reset rod 2225 is perpendicular to the length direction of the pressure cover 2201, and the end of the reset rod 2225 is positioned in front of the sliding block 2221. As the pressure cover 2201 rotates, the end of the reset rod 2225 can be raised or lowered. When the end of the reset rod 2225 is raised, the end of the reset rod 2225 contacts the sliding block 2221 and pushes the sliding block 2221 to move backward and reset. Specifically, optionally, the reset rod 2225 is generally L-shaped, with one side of the L-shaped rod connected to the bottom of the pressure cover 2201.

[0113] In an optional embodiment, if the pressure cap 2201 has sufficient installation space, the reset rod 2225 can be a straight rod that is installed vertically relative to the bottom surface of the pressure cap 2201.

[0114] In an optional embodiment, the end of the reset rod 2225 is a smooth structure, which helps to reduce the friction between the end of the reset rod 2225 and the front end face of the sliding block 2221 when the reset rod 2225 pushes the sliding block 2221 to reset. Alternatively, the smooth structure can be replaced with a roller structure or a ball bearing structure to transform sliding friction into rolling friction, further reducing friction. As shown in FIG6, this embodiment selects a structure in which a roller is installed at the end of the reset rod 2225.

[0115] As an example, as shown in Figures 6 and 7, the unlocking component 2224 includes an unlocking rod and a second elastic reset component. The unlocking rod is disposed inside the first handle 11, and a hook is provided on the lower side of the unlocking rod. The top end of the unlocking rod extends out of the mating surface between the first handle 11 and the pressure cover 2201. The sliding block 2221 is provided with a slot, and the hook engages in the slot. When the clamping assembly clamps the bare fiber, the pressure cover 2201 presses the unlocking rod, and the hook disengages from the slot. The second elastic reset component is disposed inside the first handle 11 and is connected to the unlocking rod. The second elastic reset component is used to reset the unlocking rod.

[0116] In one optional embodiment, the unlocking rod is at least an L-shaped or J-shaped component, the short horizontal side of the L-shaped unlocking rod is the hook, and the upper hook of the J-shaped unlocking rod is the hook; correspondingly, when using the L-shaped unlocking rod, the slot is provided on the bottom side of the sliding block 2221, and when using the J-shaped unlocking rod, the slot is provided on the bottom surface of the sliding block 2221.

[0117] In an optional embodiment, the second elastic reset member is disposed inside the first handle 11 near the sliding block 2221. The second elastic reset member is a compression spring. When the pressure cover 2201 presses the unlocking rod, the compression spring is compressed and stores force. When the pressure cover 2201 resets, the unlocking rod resets under the thrust of the compression spring. Of course, the above-mentioned compression spring can be replaced by a folding spring, a rubber block, a piston, an elastic metal sheet, or other components that can provide thrust.

[0118] In an optional embodiment, the second elastic reset member is disposed inside the first handle 11 near the pressure cover 2201. The second elastic reset member is a tension spring. When the pressure cover 2201 presses the unlocking lever, the tension spring is stretched and stores force. When the pressure cover 2201 resets, the unlocking lever resets under the tension of the tension spring. Of course, the above-mentioned tension spring can be replaced with a rubber band, piston, or other components that can provide tension.

[0119] As an example, as shown in Figures 6 and 7, the striking assembly includes a hammer 2231 and a second elastic element; the hammer 2231 is slidably connected to the bottom of the pressure cover 2201, and the hammer 2231 is used to strike the bare fiber. After the fiber end face shaper is closed, the hammer 2231 abuts against the protrusion 2223; the second elastic element is disposed inside the pressure cover 2201, and the second elastic element is used to eject the hammer 2231 from the pressure cover 2201. When the unlocking member 2224 unlocks the sliding block 2221, the protrusion 2223 moves with the sliding block 2221 and disengages from the hammer 2231, and the hammer 2231 is ejected to strike the bare fiber. That is to say, under the action of the second elastic element, the hammer 2231 is usually exposed at the bottom of the cover 2201; when the cover 2201 is closed to the first handle 11, the hammer 2231 slides back into the cover 2201 due to the stopping action of the protrusion 2223, during which the second elastic element stores force; when the protrusion 2223 moves with the sliding block 2221, the protrusion 2223 stops stopping the hammer 2231, the stored force of the second elastic element is released, and the hammer 2231 is pushed out of the bottom of the cover 2201, breaking the bare fiber during the pushing process.

[0120] The working principle of the fiber endface forming device described here adopts the stress cutting method. Utilizing the brittleness of optical fiber, a cutter 2222 (usually a steel blade or even a laser cutter) is used to cut a "wound" (a tiny damage line) on the surface of the bare fiber. When the fiber is slightly bent, this tiny damage point causes stress concentration. Due to the brittleness of the fiber material, a large stress gradient is generated near the damage point. When the stress exceeds the strength limit of the fiber material, the fiber will break along this damage point. This is because the stress at the damage point is much higher than the rest of the fiber, causing the material to break preferentially at this point. After the fiber breaks, the fracture surface is usually smooth because the break occurs at the damage point. The selection and manufacturing of the damage point are very precise, ensuring the quality and consistency of the fracture surface. This allows for the fabrication of the fiber endface, ensuring good optical contact and low-loss signal transmission.

[0121] In an optional implementation, the aforementioned protrusion 2223 and hammer 2231 have a contact process and a relative movement process, and there is a large friction between the contact surfaces. In some feasible ways, the protrusion 2223 can be replaced with a row of rollers or a row of balls to reduce the friction.

[0122] It can be seen that in this embodiment, there is a need to reduce friction at both the protrusion 2223 and the end of the reset rod 2225. The purpose of this is because the pressure cap 2201 is reset by the first elastic reset member 23 and the sliding block 2221 is driven by the first elastic member. Reducing friction can fully release the elastic force of the first elastic reset member 23 and the first elastic member, avoid fatigue, and extend service life.

[0123] In one optional embodiment, the second elastic element can store force through tension or compression. That is, the second elastic element can be a tension spring, rubber band, piston, or other component capable of providing tension, or a compression spring, folding spring, rubber block, piston, elastic metal sheet, or other component capable of providing thrust, with only slight differences in its placement. The positional relationship between the second elastic element and the hammer 2231 can be referenced to the aforementioned positional relationship between the second elastic reset element and the unlocking rod, and will not be repeated here.

[0124] As an example, as shown in Figures 3, 7, and 10, the first handle 11 is provided with a first cavity 1101, the sliding block 2221, the cutter 2222, and the protrusion 2223 are disposed within the first cavity 1101, and the reset rod 2225 extends into the first cavity 1101. As shown in Figures 1 to 3, the second handle 12 is provided with a second cavity 1201, and as shown in Figures 1 to 9, the third handle 21 passes through the second cavity 1201 and penetrates the second handle 12. The above exemplary description, by accommodating the cutting assembly within the first handle 11 through the first cavity 1101 and using the second cavity 1201 as a channel for the third handle 21, allows the fiber optic stripper to be as compact and small as possible, saving space, facilitating one-handed operation, and making it suitable for use in confined spaces.

[0125] In an optional implementation, referring to the coordinate system in FIG7, the first handle 11 and the cutting component can also be offset left and right, and the second handle 12 and the third handle 21 can also be offset left and right.

[0126] As an example, as shown in Figures 1 to 4 and Figures 6 to 21, the pressure cap 2201 is connected to the upper part of the first handle 11. When the first handle 11 and the second handle 12 are held with one hand, the pressure cap 2201 protrudes relative to the hand and does not obstruct the view, making it convenient for the operator to use the fiber end face shaper including the pressure cap 2201.

[0127] As an example, as shown in Figure 1, the fiber optic stripper is equipped with a locking member 44. The locking member 44 is used to close the cover 2201, which reduces the opening and closing degree of the cover 2201, reduces space occupation, and facilitates the packaging and transportation of the fiber optic stripper. Specifically, the locking member 44 includes a locking hook and a locking pin. The locking hook is rotatably mounted on one of the fiber optic stripper and the cover 2201, while the locking pin is fixedly mounted on the other. After the cover 2201 is closed, the locking hook can rotate and engage with the locking pin, thereby locking the cover 2201. In particular, the rotating connection part of the locking hook is disposed on the second handle 12, so that the cover 2201, the first handle 11, and the second handle 12 can be brought together and locked, as shown in Figure 1.

[0128] In an optional embodiment, the fiber optic stripper head 14 includes a first stripper 41 and a second stripper 42. The first stripper 41 is connected to the second handle 12, and the second stripper 42 is connected to the first handle 11. The first stripper 41 and the second stripper 42 are provided with a pigtail yarn cutting opening, a pigtail loose tube stripping opening, a pigtail tight tube stripping opening, an optical fiber coating stripping opening, and a guide block. The guide block is provided with a 3.0mm×1.8mm drop fiber guide opening and a 2.0mm×1.6mm drop fiber guide opening.

[0129] In an optional embodiment, the first stripper 41 and the second stripper 42 are each connected to a cleaning component 43. The two cleaning components 43 open and close with the opening and closing of the fiber optic stripper head 14. When the fiber optic stripper head 14 is closed, the two cleaning components 43 close accordingly, and the clamping surface formed by the closure is used for cleaning the bare fiber. Specifically, the cleaning component 43 includes a mounting base and a cleaning sponge block wrapped around the mounting base.

[0130] In an optional embodiment, as shown in Figures 1 to 7, the first handle 11 and the second handle 12 each include a metal handle portion and a plastic shell portion. The metal handle portion of the first handle 11 is integrally formed with the second peeling blade 42, and the metal handle portion of the second handle 12 is integrally formed with the first peeling blade 41. The plastic shell portion of the first handle 11 is connected to the metal handle portion of the first handle 11, and the plastic shell portion of the first handle 11 covers the cutting assembly. The pressure cap 2201 is connected to the plastic shell portion of the first handle 11, and the plastic shell portion of the second handle 12 is connected to the metal handle portion of the second handle 12. The plastic shell portion of the second handle 12 can partially cover the transmission component and partially cover the third handle 21. The pressure cap 2201 may also be a plastic shell. The plastic shell portion and the plastic shell are made of engineering plastic.

[0131] As an example, referring to the processes in Figures 6 and 7, the fiber end-face shaper 22 can be closed by simultaneously gripping the second handle 12 and the third handle 21. Referring to the processes in Figures 19 and 20, the fiber end-face shaper 22 can also be closed by first gripping the second handle 12 and then gripping the third handle 21.

[0132] The fiber optic stripper of this invention integrates a fiber end-face shaper 22 onto the stripper. The first handle 11 and the second handle 12 control the opening and closing of the fiber optic stripper head 14 via the hinge 13. The first handle 11 and the third handle 21 control the opening and closing of the fiber end-face shaper 22 via the hinge point and the transmission component. The two hinge points of the three handles are close together, making the fiber optic stripper head 14 and the fiber end-face shaper 22 close in position, and the three handles close in position as well. This allows for single-handed operation of all three handles, enabling direct use of both the fiber optic stripper head 14 and the fiber end-face shaper 22. In other words, the aforementioned fiber processing and bare fiber end-face shaping functions can be completed by operating the first handle 11, the second handle 12, and the third handle 21 with one hand, without needing to switch between different tools or even adjust the state of the tool's functional parts. This high flexibility and promising application prospects make the stripper highly flexible.

[0133] Example 2

[0134] The fiber optic stripper (not shown) of this invention differs from Embodiment 1 in that, in this embodiment, there is an angle between the rotation planes of the first handle 11 and the second handle 12 and the rotation planes of the first handle 11 and the third handle 21.

[0135] In this manner, the dexterity of the fingers and palm is utilized. The fingers hold the first handle 11 and the second handle 12 to control the opening and closing of the fiber optic stripper head 14, while the palm supports or releases the third handle 21 to rotate relative to the first handle 11, thereby controlling the opening and closing of the fiber optic end face shaper 22.

[0136] Example 3

[0137] As shown in Figures 6 to 21, a method for using fiber optic strippers as described in Example 1 to process drop optical fibers includes the following steps:

[0138] Step 1: As shown in Figures 8 and 9, the operator holds the drop fiber with their left hand and the fiber stripper with their right hand, and passes the drop fiber through the corresponding size drop fiber guide opening, with a length of not less than 40mm.

[0139] Step 2: As shown in Figure 11, close the first handle 11 and the second handle 12 with your right hand, and use the first stripper 41 and the second stripper 42 to cut the steel wire inside the drop fiber and the outer sheath of the drop fiber.

[0140] Step 3: As shown in Figure 12, use your left hand to pull the drop fiber along the direction of the arrow in the figure to peel off the outer sheath of the drop fiber.

[0141] Step 4: As shown in Figure 13, release the first handle 11 and the second handle 12 with your right hand, and place the stripped outer sheath of the fiber optic cable into the fiber coating stripping blade with your left hand.

[0142] Step 5: As shown in Figure 14, close the first handle 11 and the second handle 12 with your right hand.

[0143] Step 6: As shown in Figure 15, use your left hand to pull the drop fiber in the direction of the arrow in the figure to strip off the coating layer of the drop fiber to form the bare fiber.

[0144] Step 7: As shown in Figure 16, release the first handle 11 and the second handle 12 with your right hand, and place the bare fiber after the coating has been removed between the two cleaning components 43 with your left hand.

[0145] Step 8: As shown in Figure 17, close the first handle 11 and the second handle 12 with your right hand, and the two cleaning components 43 will close and clamp the bare fiber.

[0146] Step 9: As shown in Figure 18, use your left hand to pull the bare fiber in the direction of the arrow in the figure to clean the bare fiber.

[0147] Step 10: As shown in Figure 19, place the cleaned fiber optic cable onto the length-fixing platform 2203 with your left hand. The bare fiber portion is guided into the bare fiber groove through the V-shaped groove, and the drop cable portion is placed into the concentric groove. Then, push the end of the drop cable portion to abut against the baffle to complete the length-fixing and positioning of the bare fiber. At this time, the bare fiber is also engaged on the second clamping pad 2212.

[0148] Step 11: As shown in Figure 20 (and referring to Figures 6 and 7), close the first handle 11 and the third handle 21 with your right hand. During the closing process, the pressure cap 2201 rotates closer to the first handle 11 until it is closed. At the same time, the first elastic reset member 23 stores force, and the first clamping pad 2211 and the second clamping pad 2212 fix and clamp the bare fiber. Meanwhile, the reset rod 2225 rotates with the pressure cap 2201, releasing the space in front of the sliding block 2221.

[0149] As the pressure cap 2201 is pressed down to the bottom, the unlocking rod in the unlocking member 2224 is pressed down by the pressure cap 2201, and the hook of the unlocking rod disengages from the slot on the sliding block 2221. At the same time, the pressing down of the unlocking rod stores force on the second elastic reset member. Meanwhile, the hammer 2231 abuts against the protrusion 2223, and the hammer 2231 slides back into the pressure cap 2201, and the second elastic member stores force.

[0150] After the hook disengages from the slot, the sliding block 2221 is unlocked. Driven by the first elastic element, the sliding block 2221 drives the cutter 2222 to move forward. During the movement, the cutter 2222 cuts and scribing lines on the bare fiber.

[0151] The sliding block 2221 simultaneously drives the protrusion 2223 to move. After the cutter 2222 completes the cut, the protrusion 2223 disengages from the hammer 2231. The stored force of the second elastic element is released, pushing the hammer 2231 to strike the bare fiber downwards. The bare fiber breaks smoothly along the cut, that is, the fiber end face is formed.

[0152] Step 12: As shown in Figure 21 (and referring to Figures 6 and 7), release the first handle 11, the second handle 12, and the third handle 21 with your right hand. The first elastic reset member 23 releases its stored force, and the pressure cap 2201 rotates and resets under the action of the first elastic reset member 23, so that the bare fiber is not clamped. At the same time, the reset rod 2225 rotates with the pressure cap 2201 and abuts against the front end surface of the sliding block 2221, pushing the sliding block 2221 to move backward. Meanwhile, the first elastic member stores its force to prepare for the next operation.

[0153] When the sliding block 2221 is pushed backward into place, the hook and the slot can re-engage. At this time, the second elastic reset member releases its stored force, causing the unlocking rod to move upward to reset. During the reset process, the hook falls back into the slot, locking the sliding block 2221.

[0154] As can be seen, in the above steps, the operator can complete all the operations of the fiber optic stripper using only their right hand, thus achieving single-handed operation. Furthermore, this embodiment is only used in conjunction with the accompanying drawings and with the right hand as an example for explanation (considering the hand habits of most people), and does not limit the fiber optic stripper to be operated only with the right hand; the fiber optic stripper is also suitable for left-handed operation.

[0155] In an optional implementation, as shown in Figures 6 and 7, after the operation in step nine is completed, the right hand can release the first handle 11 and the second handle 12, and in step eleven, simultaneously tighten the first handle 11, the second handle 12 and the third handle 21.

[0156] The present invention describes a method for using a fiber optic stripper. By integrating a fiber optic stripper head 14 and a fiber optic end-face shaper 22 into a single pair of pliers, the tool can perform fiber-to-bare fiber processing using the fiber optic stripper and then perform end-face shaping on the bare fiber using the fiber optic end-face shaper 22. Furthermore, the aforementioned fiber processing and bare fiber end-face shaping functions can be completed by operating the first handle 11, the second handle 12, and the third handle 21 with one hand, without the need to switch between different tools or even adjust the state of the tool's functional parts. This method offers high flexibility and excellent results.
