Description

Technical Field

[0001] This invention belongs to the field of optical fiber cutting technology, specifically an optical fiber cutting device for an optical fiber fusion splicer. Background Technology

[0002] Fiber optic fusion splicers are mainly used for the construction and maintenance of optical cables in optical communication, hence the name "optical cable fusion splicer." In scenarios such as optical fiber communication engineering construction and optical fiber equipment maintenance, fusion splicers are the core equipment for achieving fast and reliable optical fiber connections. Their operation process typically includes key steps such as fiber stripping, cleaning, cutting, and splicing. Each step requires the use of various auxiliary tools, placing high demands on the continuity and convenience of operation.

[0003] For example, application CN222167268U discloses an embedded fiber optic fusion splicer, including a fiber optic fusion splicer body and a bottom shell. The bottom shell is installed on the bottom of the fiber optic fusion splicer body, and an embedding mechanism is also included. The embedding mechanism includes a mounting plate, a base, a U-shaped insert plate, an inner stop bar, vertical legs, a notch plate A, and a notch plate B. The embedding mechanism is set at the bottom shell of the fiber optic fusion splicer body. The base of the embedding mechanism can carry fiber optic splicing tools. When the U-shaped insert plate of the embedding mechanism is pulled out, the tools can be taken out. The U-shaped insert plate can be unfolded outside the fiber optic fusion splicer body to form a tool placement platform, which facilitates the placement of fiber optic splicing tools. Furthermore, the sheathed fiber can be alternately wound at multiple sets of notch plates A and B in the groove to form an anti-pull structure, so that when the sheathed fiber is accidentally pulled, it will not detach from the fiber optic fusion splicer body, ensuring the convenient use of the fiber optic fusion splicer body outdoors.

[0004] When using the aforementioned devices, the existing fiber optic splicing process requires operators to use multiple tools such as thermal strippers, cleaning tools, and cutting tools. This necessitates frequent handling of different tools, reducing efficiency and increasing the risk of tools being lost due to careless placement. Furthermore, storing these scattered tools requires additional storage space, leading to a cluttered work area and hindering the secure storage of other tools, further impacting the orderly execution of the operation. Therefore, this paper proposes a fiber optic cleaving device for fiber optic splicing machines to address the problems described in the background section. Summary of the Invention

[0015] Preferably, a support is fixedly connected to the rear end of the fiber melting machine body, and a support plate is fixedly connected to the top end of the support.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, by incorporating a fiber optic fusion splicer body, thermal stripping pliers, a cleaning mechanism, and a storage mechanism, allows for convenient simultaneous thermal stripping and cleaning of optical fibers without the need for manual wiping with a cloth. After use, the thermal stripping pliers and cleaning mechanism can be directly stored within the front of the fusion splicer body via the storage mechanism, making them an integral part of the machine and preventing loss. Furthermore, the fusion splicer body does not occupy excessive space during storage, allowing for the secure storage of other tools. The integrated design of all tools facilitates use by staff, eliminating the need to search for individual tools and further avoiding the inconvenience caused by haphazard tool placement.

[0017] This invention, by incorporating a linear module, a swing arm, a fiber optic cleaver, a moving frame, a positioning mechanism, and a fiber clamping mechanism, eliminates the need for manual pulling and stripping of optical fibers, preventing hand injuries from repeated pulling. It also facilitates the cutting of the stripped fiber. In practice, the fiber is first placed on two clamping seats, and the two pressing plates are pressed down to clamp and fix the fiber to the seats. Then, as the fiber begins to be thermally stripped using the thermal stripping pliers, the linear module moves the fiber optic cleaver to the left, causing the moving frame and cleaver to pull the fiber out of the thermal stripping pliers until it is removed from the cleaning mechanism. Then, the moving frame will be positioned at the left end of the linear module. Next, the clamping and fixing of the fiber on the fiber cleaver will be released, and the fiber cleaver will be moved to the right using the linear module to separate the fiber cleaver from the moving frame. Throughout this process, the fiber on the moving frame will be clamped to prevent it from loosening. When the fiber to be stripped is located on the fiber cleaver, the operator will operate the fiber cleaver to cut the fiber. After cutting, the fixing of the fiber on the moving frame will be released again, and the operator will take out the fiber and place it at the fusion splice interface of the fusion splicer body and fix it. Then, place the other fiber at the fusion splice interface of the fusion splicer body and fix it. The splicing of the two fibers can then begin.

[0018] This invention, through the implementation of a linkage mechanism, allows personnel to easily move the linear module closer to the left side of the fiber melting machine body, reducing its space occupation after storage and ensuring the stability of the linear module after deployment, preventing it from swinging arbitrarily. In specific operation, the operator presses down on the second lever to separate the top of the second locking block from the second locking slot. Then, pushing the second lever causes the sliding plate to slide within the sliding frame, causing the connecting plate to push the linear module to swing around the hinge point between the swing rod and the fiber melting machine body until the linear module swings 90°. At this point, the second locking block will also slide to the second locking slot on the rear side, utilizing the second compression spring. Under the elastic force, the second locking block can automatically push into the second locking slot, which limits the sliding plate and prevents it from sliding freely in the sliding frame. It also further ensures the stability of the linear module during operation. After the linear module is used up, the operator can press down the second lever again to separate the second locking block from the second locking slot on the rear side and slide it forward, causing the connecting plate to pull the linear module to swing until the linear module swings to the left side of the fiber melting machine body. At this time, the second locking block will automatically insert into the second locking slot on the front side to prevent the sliding plate, connecting plate and linear module from moving. The above operation is more convenient and facilitates quick use by the operator. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 16 As shown, the present invention provides an optical fiber cleaving device for an optical fiber fusion splicer, including a fusion splicer body 1. A hot stripper 5 is provided at the front end of the fusion splicer body 1. A cleaning mechanism for wiping optical fibers is detachably connected to the pressure cap and base of the hot stripper 5. A storage mechanism for supporting the hot stripper 5 and facilitating subsequent storage is provided on the front of the fusion splicer body 1. A linear module 8 is provided on the left side of the fusion splicer body 1. A swing rod 21 is fixedly connected to the bottom surface of the linear module 8. One end of the swing rod 21 is hinged to the left side of the fusion splicer body 1. An optical fiber cleaver 9 is installed on the slider of the linear module 8. A moving frame 10 is horizontally slidably provided on the linear module 8, and the moving frame 10 is magnetically connected to the optical fiber cleaver 9. A positioning mechanism for limiting the displacement of the moving frame 10 is provided at the left end of the linear module 8. A fiber clamping mechanism for clamping optical fibers is provided between the moving frame 10 and the optical fiber cleaver 9. A linkage mechanism for adjusting the swing of the linear module 8 is provided on the left side of the fusion splicer body 1.

[0023] Using the above scheme: Before splicing the two optical fibers, firstly, the moving frame 10 and the fiber cleaver 9 are moved to the left side of the mounting plate 6 via the linear module 8. Then, the optical fiber is placed on the moving frame 10, the fiber cleaver 9, and the thermal stripper 5. Subsequently, the fiber is pressed and fixed onto the moving frame 10 and the fiber cleaver 9 by the fiber pressing mechanism. Next, the fiber is thermally stripped using the thermal stripper 5. Then, the operation of the linear module 8 drives the fiber cleaver 9 and the moving frame 10 to the left, allowing personnel to press the cap of the thermal stripper 5 to remove the outer sheath and coating of the optical fiber. The stripped portion is then wiped clean by the cleaning mechanism and moved away from the cleaning mechanism. At this time, the moving frame 10 is fixed and restricted to the left end of the linear module 8 by the positioning mechanism to prevent it from moving arbitrarily. Then, the pressure on the fiber cleaver 9 is released, and the linear module 8 drives the fiber cleaver 9 to the right until the stripped portion of the fiber is on the fiber cleaver 9, at which point the cutting process can begin. Then, the pressure on the fiber cleaver 9 is released, and the fiber cleaver 9 is moved to the right by the linear module 8 until the stripped portion of the fiber is on the fiber cleaver 9. In addition to the clamping effect on the optical fiber on the moving frame 10, the optical fiber can be removed from the moving frame 10 and the optical fiber cleaver 9 and placed into the fusion splice interface of the fusion splicer body 1. Repeat the above steps to strip, clean and cut the two optical fibers respectively. After the two optical fibers are cut, before that, put a sleeve on the surface of one of the optical fibers to facilitate the subsequent heat shrinking treatment between the two optical fibers. In addition, after the hot stripping pliers 5 and the straight module 8 are used, the hot stripping pliers 5 and the cleaning mechanism can be stored in the front of the fusion splicer body 1 using the storage mechanism. Then, the linkage mechanism drives the straight module 8 to swing to the left side of the fusion splicer body 1, so that the straight module 8 is close to the left side of the fusion splicer body 1. Therefore, it will not take up more space when storing the fusion splicer body 1, and other tools can also be stored stably. The tools have the effect of being assembled into one unit, which is convenient for the staff to use. There is no need for the staff to search for the tools, and further avoids the inconvenience of searching for tools caused by random placement.

[0024] It is worth noting that the above tools are all existing mature equipment, so their working principles will not be described in detail. Furthermore, the fiber optic cleaver 9, the moving frame 10, and the hot stripping pliers 5 are all set to be on the same horizontal plane to facilitate the horizontal placement of the fiber optic cable, which is conducive to the orderly processing of fiber stripping, wiping, and cutting.

[0025] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figures 12 to 14As shown, the cleaning mechanism includes a mounting plate 6. The cover and base of the hot peeling pliers 5 are both provided with a third slot 12. One end of the mounting plate 6 is inserted into the corresponding third slot 12. Two positioning rods 55 are fixedly connected to the inner wall of the mounting plate 6. Mounting blocks 49 are sleeved on the two positioning rods 55. Cleaning cotton 48 is sleeved on the surface of the mounting block 49. The cleaning cotton 48 is slidably disposed in the mounting plate 6. Two baffles 37 are connected to the left end of the mounting plate 6 through a damping shaft. One end of the baffle 37 abuts against the left side of the mounting block 49 and the cleaning cotton 48.

[0026] The above solution allows for convenient and quick assembly of the two mounting plates 6 onto the thermal stripper 5. In practice, simply insert one end of each mounting plate 6 directly into the corresponding third slot 12 to quickly complete the assembly. After the optical fiber is thermally stripped by the thermal stripper 5, it can be wiped by the pressure between the two cleaning cotton balls 48 when pulled. Beforehand, personnel spray alcohol onto the two cleaning cotton balls 48 to ensure effective cleaning of the optical fiber. When the cover of the thermal stripper 5 is opened, it will open the mounting plate 6 above, thus not hindering the normal handling of the optical fiber. Furthermore, when the adjacent surfaces of the two cleaning cotton balls 48 are dirty, the two baffles 37 on the mounting plate 6 can be swung to release the obstruction of the mounting block 49 and the cleaning cotton balls 48. After pulling the cleaning cotton balls 48 and the mounting block 49 out of the mounting plate 6, they can be removed, repositioned, and reassembled.

[0027] like Figure 1 , Figures 7 to 11 As shown, the storage mechanism includes a first storage slot 2 and a movable plate 3. The first storage slot 2 is located on the front of the meltblown fiber machine body 1, and the size of the first storage slot 2 is adapted to the size of the hot stripping pliers 5 and the cleaning mechanism. A second storage slot 44 is provided inside the first storage slot 2. The movable plate 3 is slidably disposed in the second storage slot 44. A swing frame 4 is hinged to the front end of the movable plate 3. The hot stripping pliers 5 is installed on the top of the swing frame 4. A first limiting mechanism for limiting the displacement of the movable plate 3 is provided inside the first storage slot 2. A second limiting mechanism for limiting the swing of the swing frame 4 is provided at the front end of the movable plate 3. A mounting hole 46 is provided at the rear end of the movable plate 3. A first tension spring 47 is fixedly connected to the inner wall of the mounting hole 46. The rear end of the first tension spring 47 is fixedly connected to the inner wall of the second storage slot 44.

[0028] The above solution allows the hot stripper 5 to be directly stored in the front end of the fiber melting machine body 1 after use, making it an integral part of the body and preventing loss. In specific operation, firstly, the first limiting mechanism is released from the restriction on the moving plate 3, allowing the moving plate 3 to move within the second storage slot 44. Then, the second limiting mechanism is released from the restriction on the swing frame 4, allowing the swing frame 4 to swing 90° at the front end of the moving plate 3 until the hot stripper 5 is laid down. Then, the hot stripper 5 can be pushed into the first storage slot 2, allowing the cleaning mechanism to also be stored in the first storage slot 2 for convenient use later. In addition, extension slots are provided on both the upper and lower sides of the first storage slot 2, and grooves are provided on the front and back of the hot stripper 5, so that personnel can easily remove the hot stripper 5 from the first storage slot 2.

[0029] like Figure 7 , Figure 8 and Figure 16 As shown, the first limiting mechanism includes a first mounting groove 40, which is opened in the first storage groove 2 and extends to the front of the melt fiber machine body 1. A first compression spring 41 is fixedly connected to the inner bottom wall of the first mounting groove 40. A first locking block 39 is fixedly connected to the top of the first compression spring 41 and is slidably disposed in the first mounting groove 40. A first locking groove 45 adapted to the first locking block 39 is opened on the bottom surface of the moving plate 3, and the top of the first locking block 39 is inserted into the first locking groove 45. A first lever 42 is fixedly connected to the bottom end of the first locking block 39, and the front end of the first lever 42 extends through the first mounting groove 40 and extends to the front of the melt fiber machine body 1.

[0030] By adopting the above solution, the first locking block 39 can be inserted into the first locking slot 45 under the elastic force of the first compression spring 41, which can ensure the stability of the moving plate 3 in the second storage slot 44 and prevent the moving plate 3 from detaching from the second storage slot 44 at will. This also ensures the overall stability of the hot stripper 5. Moreover, when the moving plate 3 moves into the second storage slot 44, the top of the first locking block 39 can also press against the side of the hot stripper 5, further preventing the hot stripper 5 from detaching from the first storage slot 2 at will, so as to ensure the stable storage of the hot stripper 5. Furthermore, the operator only needs to push the first lever 42 down to retract the first locking block 39 into the first mounting slot 40 to release the restriction on the moving plate 3 or the hot stripper 5.

[0031] like Figures 8 to 11As shown, the second limiting mechanism includes a third mounting groove 53 and two positioning holes 50. The third mounting groove 53 is opened on one side of the front end of the moving plate 3. The two positioning holes 50 are both opened on one side of the bottom end of the swing frame 4, and the included angle between the two positioning holes 50 is 90°. A rod 51 is slidably provided through the inner wall of the third mounting groove 53. One end of the rod 51 is inserted into the corresponding positioning hole 50. The other end of the rod 51 is fixedly connected to a pull plate 52. A second tension spring 54 is sleeved on the surface of the rod 51. The two ends of the second tension spring 54 are respectively fixedly connected to the inner wall of the third mounting groove 53 and the surface of the pull plate 52.

[0032] Using the above solution: when the swing frame 4 is in a vertical state within the moving plate 3, the insert rod 51 is inserted into the corresponding positioning hole 50 to prevent the swing frame 4 from swinging arbitrarily, thus ensuring the stable use of the hot stripper 5. When it is necessary to swing the swing frame 4 within the front end of the moving plate 3, the pull plate 52 is pulled to remove the insert rod 51 from the positioning hole 50. Then, the swing frame 4 is laid down, and the pull plate 52 is released. Under the elastic force of the second tension spring 54, the insert rod 51 is automatically inserted into the corresponding positioning hole 50, thus ensuring the stability of the swing frame 4 after it is laid down.

[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 15 As shown, a sleeve block 31 is fixedly connected to the bottom end of the movable frame 10, and a sliding groove 32 is provided on the upper surface of the linear module 8. A guide rod 33 is fixedly connected to the inner wall of the sliding groove 32. The sleeve block 31 is slidably disposed in the sliding groove 32 and sleeved on the guide rod 33. Sliding grooves 32 are fixedly connected to the four adjacent corners of the fiber optic cleaver 9 and the movable frame 10, and the fiber optic cleaver 9 and the movable frame 10 are mutually attracted and connected through the sliding grooves 32.

[0034] The above solution ensures that the movable frame 10 slides stably and horizontally on the linear module 8. When the movable frame 10 approaches the fiber optic cleaver 9, the sliding groove 32 can be used to automatically attach the movable frame 10 and the fiber optic cleaver 9 together for easy use. When the movable frame 10 is located at the left end of the linear module 8 through the positioning mechanism, the fiber optic cleaver 9 will move to the right and automatically separate from the movable frame 10.

[0035] like Figure 5 and Figure 15 As shown, the positioning mechanism includes a swing rod 21 and a horizontal plate 34. The swing rod 21 is fixed to the left side of the movable frame 10, and the horizontal plate 34 is fixed to the left end of the linear module 8. Two vertical plates 35 are fixed to the horizontal plate 34, and a swing plate 13 is rotatably connected between the two vertical plates 35. A third locking block 38 adapted to the swing rod 21 is provided at the right end of the swing plate 13, and a spring 36 is fixed to the left end of the swing plate 13, and the spring 36 is fixed to the horizontal plate 34.

[0036] Using the above scheme: when the movable frame 10 is pushed to the swing plate 13 by the fiber optic cleaver 9, the swing rod 21 will automatically engage with the third locking block 38 to prevent the movable frame 10 from moving arbitrarily on the linear module 8. Subsequently, when the fiber optic cleaver 9 moves to the right through the linear module 8, the movable frame 10 and the fiber optic cleaver 9 will automatically separate. Only when the operator presses down on the left end of the swing plate 13 can the engagement between the third locking block 38 and the swing rod 21 be released. Then, the operator can push and slide the movable frame 10 toward the fiber optic cleaver 9 to quickly connect the movable frame 10 and the fiber optic cleaver 9.

[0037] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the fiber pressing mechanism includes two pressing plates 11 and two fixed frames 28. The bottom ends of the two pressing plates 11 are elastically hinged to the corresponding movable frame 10 and fiber optic cleaver 9, respectively. The two fixed frames 28 are fixedly connected to the front ends of the movable frame 10 and fiber optic cleaver 9, respectively. The bottom surfaces of the two pressing plates 11 are each fixedly connected to a pressing block 26. The movable frame 10 and fiber optic cleaver 9 are each provided with a pressing seat 14. The front ends of the two pressing plates 11 are each fixedly connected to a first insert plate 7. The two fixed frames 28 are each provided with a first locking plate 30, and the first insert plate 7 is adapted to the first locking plate 30. The bottom of the two first locking plates 30 is each fixedly connected to a pressing cylinder 29, and the pressing cylinder 29 slides through to the front of the fixed frame 28. The two pressing cylinders 29 are each fixedly connected to a third compression spring 43, and one end of the third compression spring 43 is fixedly connected to the inner wall of the fixed frame 28.

[0038] The above solution facilitates the compression and fixation of optical fibers located on the moving frame 10 and the fiber optic cleaver 9. Specifically, the optical fiber is first placed on the two compression seats 14, then the two pressing plates 11 are pressed down directly, causing the two first insert plates 7 to be inserted into the corresponding fixing frames 28 and secured by the first locking plates 30. During this process, the optical fiber is compressed onto the compression seats 14 by the compression blocks 26, ensuring that subsequent fiber stripping does not require manual pulling, preventing hand injuries from repeated pulling. When the optical fiber needs to be separated from the compression seats 14, simply press the two pressing cylinders 29 to automatically release the two pressing plates 11, allowing the optical fiber to be removed. Once the optical fiber begins to be stripped by the hot stripping pliers 5, the operation of the linear module 8 drives the fiber optic cleaver 9 to move to the left, thereby pulling the moving frame 10 and the fiber optic cleaver 9 together. The optical fiber is pulled out from the thermal stripper 5, removing the coating layer and wiping away surface impurities using a cleaning mechanism. No additional cleaning is required. Once the optical fiber is removed from the cleaning mechanism, the moving frame 10 is positioned at the left end of the linear module 8. The fiber cleaver 9 is then released from its clamping and fixing position, and the linear module 8 controls the fiber cleaver 9 to move to the right, separating it from the moving frame 10. Throughout this process, the optical fiber on the moving frame 10 remains clamped to prevent it from loosening. When the stripping point is located on the fiber cleaver 9, the operator uses the fiber cleaver 9 to cut the optical fiber. After cutting, the fixing on the moving frame 10 is released, and the operator removes the optical fiber and places it at the fusion splice interface of the fusion splicer body 1 and fixes it. Another optical fiber is then placed at the fusion splice interface of the fusion splicer body 1 and fixed. The splicing of the two optical fibers can then begin.

[0039] like Figures 2 to 4 and Figure 7 As shown, the linkage mechanism includes a connecting plate 20 and a sliding frame 17. One end of the connecting plate 20 is hinged to the bottom surface of the linear module 8. The sliding frame 17 is fixed to the left side of the fiber melting machine body 1. A slide plate 18 is slidably disposed on the inner wall of the sliding frame 17. The other end of the connecting plate 20 is hinged to the rear end of the slide plate 18. Two second slots 25 are opened on the inner top wall of the sliding frame 17. A second mounting groove 23 is opened on the top front end of the slide plate 18, and the second mounting groove 23 penetrates the side of the slide plate 18. A second locking block 22 is slidably disposed inside the second mounting groove 23, and the top end of the second locking block 22 is inserted into the corresponding second slot 25. A second lever 19 and a second compression spring 24 are fixedly connected to the bottom end of the second locking block 22. The bottom end of the second compression spring 24 is fixedly connected to the inner bottom wall of the second mounting groove 23. One end of the second lever 19 penetrates the second mounting groove 23 and extends to the side of the slide plate 18.

[0040] The above solution allows personnel to easily move the linear module 8 to the left side of the meltblown fiber machine body 1, reducing its space occupation after storage. It also ensures the stability of the linear module 8 after unfolding, preventing it from swinging arbitrarily. Specifically, personnel press down on the second lever 19 to separate the top of the second locking block 22 from the second locking slot 25. Then, pushing the second lever 19 causes the slide plate 18 to slide within the sliding frame 17, causing the connecting plate 20 to push the linear module 8 to swing around the hinge point between the swing rod 21 and the meltblown fiber machine body 1 until the linear module 8 swings 90°. At this point, the second locking block 22 will slide to the rear second locking slot 25, utilizing the elasticity of the second compression spring 24. The second locking block 22 automatically engages with the second locking slot 25, limiting the sliding plate 18 and preventing it from sliding freely within the sliding frame 17. This further ensures the stability of the linear module 8 during operation. After the linear module 8 is used, the operator can press down the second lever 19 again to disengage the second locking block 22 from the rear second locking slot 25 and slide it forward. This causes the connecting plate 20 to pull the linear module 8 to swing until it reaches the left side of the fiber melting machine body 1. At this point, the second locking block 22 will automatically insert into the front second locking slot 25, preventing the sliding plate 18, connecting plate 20, and linear module 8 from moving. This operation is more convenient and allows for quick and easy use by the operator.

[0041] like Figure 1 , Figure 2 and Figure 7 As shown, a bracket 15 is fixedly connected to the rear end of the fiber melting machine body 1, and a support plate 16 is fixedly connected to the top end of the bracket 15.

[0042] Using the above solution: After personnel complete the fusion splicing and heat shrinking of the two optical fibers through the fusion splicer body 1, they can be placed directly on the tray 16 for cooling, avoiding the messy working environment caused by the random placement of optical fibers.

[0043] The working principle and usage process of this invention are as follows: Before splicing two optical fibers, the thermal stripper 5 is first pulled out from the fusion splicer body 1 and positioned at the front. The linear module 8 is then placed to the left of the thermal stripper 5. The optical fiber is then placed on the two compression seats 14, with one end inserted into the cover and base of the thermal stripper 5. Next, the operator presses down on the cover of the thermal stripper 5 to perform thermal stripping on the optical fiber. Simultaneously, the operator turns on the power to the linear module 8, causing it to move the fiber cleaver 9 and the moving frame 10 to the left. This pulls the optical fiber to the left, allowing one end to smoothly detach from the thermal stripper. The outer sheath and coating are stripped off using clamps 5. During this process, the stripped portion of the optical fiber can be cleaned by wiping with two cleaning cotton pads 48. After the stripped portion of the optical fiber separates from the two cleaning cotton pads 48, the second insertion plate 27 will then press against the third locking block 38 until the third locking block 38 locks and limits the second insertion plate 27, preventing the moving frame 10 from moving arbitrarily on the linear module 8. Then, the pressure on the optical fiber cleaver 9 is released. Simply press the corresponding pressing cylinder 29 to release the first locking plate 30 from locking the first insertion plate 7. Then, the linear module 8 drives the fiber optic cleaver 9 to move to the right until the stripped portion of the fiber is on the cleaver 9, at which point the cutting process can begin. After cutting, the clamping force on the fiber on the moving frame 10 is released, and the above steps are repeated to strip, clean, and cut the two fibers separately. After the two fibers are cut, they can be placed into the fusion splice port of the fusion splicer body 1. Before this, a sleeve is inserted into the surface of one of the fibers to facilitate the subsequent heat shrinking treatment between the two fibers. Finally, when the heat stripping pliers 5 and the linear module 8 move to the right, the fiber stripping pliers 9 move to the right. After the use of Group 8, the hot stripping pliers 5 and the cleaning mechanism can be stored in the front of the fusion splicer body 1 using the storage mechanism. Then, the linkage mechanism drives the linear module 8 to swing to the left side of the fusion splicer body 1, so that the linear module 8 is close to the left side of the fusion splicer body 1. Therefore, it will not take up more space when storing the fusion splicer body 1 in the future, and other tools can also be stored stably. The tools have the effect of being assembled into one unit, which is convenient for the staff to use. There is no need for the staff to search for the tools, and further avoids the inconvenience of searching for tools caused by random placement.
