[0019] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Embodiment 1:

[0021] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a fiber optic cable stripping pliers, which can be mainly applied to the installation and construction process of communication optical fibers.

[0022] As Figure 1 and Figure 2As shown, the fiber optic cable stripping pliers include a first pliers rod and a second pliers rod that are hinged to each other. When the jaws of the first pliers rod and the jaws of the second pliers rod are closed, a plurality of jaws are formed, and the plurality of jaws are used to respectively strip a plurality of different coating layers of the fiber optic cable.

[0023] The materials of the first pliers rod and the second pliers rod can be high carbon steel that has been quenched to improve the overall strength of the first pliers rod and the second pliers rod.

[0024] Exemplarily, the outer sides of the handles of the first pliers rod and the second pliers rod are both coated with a flexible protective layer to facilitate the holding by the staff. The flexible protective layer can be rubber, plastic, etc.

[0025] In actual use, by holding the handles of the first pliers rod and the second pliers rod, the staff can make the handles of the first pliers rod and the second pliers rod approach or open relative to each other, so that the jaws of the first pliers rod and the jaws of the second pliers rod are closed or separated, in order to grip or release the fiber optic cable through the plurality of jaws.

[0026] The fiber optic cable has a plurality of coating layers with different thicknesses from the outside to the inside. The sizes of the plurality of jaws can respectively correspond to the inner diameter sizes of the different coating layers, so as to sequentially strip the plurality of different coating layers of the fiber optic cable from the outside to the inside, exposing the optical fiber in the fiber optic cable, which is convenient for subsequent construction.

[0027] By providing a plurality of jaws on the fiber optic cable stripping pliers, the same fiber optic cable stripping pliers can be used without changing tools when stripping a plurality of different coating layers of the fiber optic cable, which is beneficial to improving work efficiency; and the staff only needs to carry one fiber optic cable stripping pliers during operation, without having to carry multiple tools, which is convenient for the staff to carry.

[0028] As Figure 2 and Figure 3 shown, the fiber optic cable stripping pliers further include a tool rest assembly. The tool rest assembly is arranged on the handle of the first pliers rod (or the second pliers rod). The tool rest assembly includes a blade anvil 2, a tool rest 4 and a blade 3. The blade anvil 2 is arranged on the outside of the handle of the first pliers rod (or the second pliers rod); the tool rest 4 is arranged opposite to the blade anvil 2 and is hinged to the handle of the first pliers rod (or the second pliers rod); the blade 3 is arranged on the tool rest 4; a cutting edge is formed between the blade anvil 2 and the blade 3, and the cutting edge is used for cutting the aramid of the fiber optic cable.

[0029] It should be noted that the blade anvil 2, the tool rest 4 and the blade 3 are simultaneously arranged on the handle of the first pliers rod, or can also be simultaneously arranged on the handle of the second pliers rod.

[0030] Exemplarily, the blade anvil 2 can be a separate component or a part of the handle of the first pliers rod (or the second pliers rod).

[0031] As Figure 2 and Figure 3As shown, the tool rest 4 is hinged to the handle of the first tong rod or the second tong rod through a rotating shaft 5.

[0032] Exemplarily, a positioning portion is provided on the tool rest 4, and positioning grooves are provided on both sides of the blade 3. The blade 3 is positioned with the tool rest 4 through the positioning grooves and the positioning portion.

[0033] When it is necessary to cut the aramid of the optical fiber ribbon, the aramid is placed in the cutting edge between the blade anvil 2 and the blade 3, and after pressing the tool rest 4, the blade 3 is driven to cut the aramid.

[0034] Therefore, the above settings further improve the functionality of the optical fiber ribbon stripper. When cutting the aramid, the same optical fiber ribbon stripper can be used without replacing tools, which is also beneficial to improving work efficiency and is convenient for the staff to carry.

[0035] Thus, for the optical fiber ribbon stripper provided by the embodiment of the present utility model, by forming a plurality of clamping jaws when the clamping heads of the first tong rod and the second tong rod are closed, the plurality of clamping jaws can respectively strip a plurality of different coating layers of the optical fiber ribbon; by providing the blade anvil 2 on the outer side of the handle of the first tong rod (or the second tong rod) and providing a tool rest 4 opposite to the blade anvil 2, and providing a blade 3 on the tool rest 4, a cutting edge can be formed between the blade anvil 2 and the blade 3 to cut the aramid of the optical fiber ribbon through the cutting edge; therefore, when the staff strips a plurality of different coating layers of the optical fiber ribbon and cuts the aramid, the same optical fiber ribbon stripper can be used without replacing tools, which is beneficial to improving work efficiency; and the staff only needs to carry one optical fiber ribbon stripper during operation and does not need to carry a plurality of tools, which is convenient for the staff to carry.

[0036] In some embodiments, as Figure 2 and Figure 3 shown, a clamping portion is provided on the tool rest 4. The optical fiber ribbon stripper further includes a locking member 1 which is rotatably arranged on the handle of the first tong rod or the second tong rod, and a clamping groove adapted to the clamping portion is provided on the locking member 1. After the tool rest 4 drives the blade 3 to press down, by rotating the locking member 1, the clamping groove can be engaged with the clamping portion to maintain the pressing-down state of the tool rest 4.

[0037] Exemplarily, the clamping portion and the blade 3 are respectively located on both sides of the tool rest 4 to avoid interference between the clamping portion and the blade 3.

[0038] When the aramid does not need to be cut, the clamping groove of the locking member 1 is engaged with the clamping portion to maintain the pressing-down state of the tool rest 4 and lock the blade 3 to prevent the blade 3 from being exposed and hurting the staff by mistake; when the blade 3 needs to be used, rotate the locking member 1, and the clamping groove of the locking member 1 is separated from the clamping portion. At this time, the blade 3 can be opened, and the cutting edge between the blade anvil 2 and the blade 3 can be normally used to cut the aramid of the optical fiber ribbon.

[0039] Through the above settings, the locking member 1 can conveniently lock and unlock the blade 3, improving the operation convenience for the staff and preventing the blade 3 from being abnormally exposed to injure the staff.

[0040] In some embodiments, as Figure 2 and Figure 3 shown, the tool rest assembly further includes a torsion spring 6. One end of the torsion spring 6 is fixed on the handle of the first tong rod (or the second tong rod), and the other end of the torsion spring 6 is fixed on the tool rest 4. After the tool rest 4 drives the blade 3 to press down, the torsion spring 6 can reset the tool rest 4.

[0041] Exemplarily, the torsion spring 6 is sleeved on the rotating shaft 5.

[0042] As Figure 2 and Figure 3 shown, after the staff presses down the tool rest 4, the tool rest 4 drives the blade 3 to press down, causing the two ends of the torsion spring 6 to approach each other and deform. The torsion spring 6 generates an outward restoring force on the tool rest 4. After the staff no longer applies pressure to the tool rest 4, the outward restoring force of the torsion spring 6 on the tool rest 4 will drive the tool rest 4 to reset to the non-pressed state.

[0043] Through the above settings, automatic reset of the tool rest 4 can be achieved, improving the operation convenience of the fiber optic cable stripping pliers.

[0044] In some embodiments, as Figure 3 shown, the blade 3 is detachably arranged on the tool rest 4 through a fastener.

[0045] Exemplarily, the fastener is a screw. A through hole is provided on the blade 3, and a threaded hole corresponding to the through hole is provided on the tool rest 4. The above screw passes through the through hole on the blade 3 and extends into the threaded hole on the tool rest 4 to fix the blade 3. When the blade 3 needs to be replaced, only the screw needs to be unscrewed.

[0046] Through the above settings, it is convenient to disassemble and replace the blade 3.

[0047] In some embodiments, as Figure 1 shown, the multiple jaws include a first jaw 7, a second jaw 8 and a third jaw 9 with different sizes. The first jaw 7 is used to strip the outer protective sleeve of the fiber optic cable, the second jaw 8 is used to strip the soft glue protective layer of the fiber optic cable, and the third jaw 9 is used to cut and strip the butterfly-shaped fiber optic cable.

[0048] The shapes and sizes of the first jaw 7, the second jaw 8 and the third jaw 9 are set according to the shapes and sizes of the different coating layers to be stripped from the fiber optic cable, so that each jaw can correspondingly strip one coating layer.

[0049] Exemplarily, the shape of the first jaw 7 is a V-shaped structure. When the jaws of the first pliers rod and the second pliers rod are closed, the size of the bottom opening of the V-shaped structure can be set to 1 mm, which can effectively strip the outer protective sleeve with a diameter of Φ2 mm - Φ3 mm of the pigtail.

[0050] Exemplarily, the shape of the second jaw 8 also adopts a V-shaped structure. When the jaws of the first pliers rod and the second pliers rod are closed, the size of the bottom opening of the V-shaped structure can be set to 0.14 mm, which can strip the white soft glue protective layer with a diameter of Φ0.6 mm - Φ0.9 mm of the pigtail and strip the coating layer with a diameter of Φ0.25 mm to the cladding with a diameter of Φ0.125.

[0051] Exemplarily, the shape of the third jaw 9 is butterfly-shaped. When the jaws of the first pliers rod and the second pliers rod are closed, the third jaw 9 can cut and strip the indoor / outdoor butterfly-shaped drop wire with a cross-section of 3 mm × 2 mm of metal or non-metal strengthening member.

[0052] Through the above settings, the outer protective sleeve and the soft glue protective layer of the pigtail can be stripped, and the butterfly-shaped drop wire can be cut and stripped.

[0053] In some embodiments, as Figure 1 and Figure 2 shown, the pigtail stripping pliers further include two circular felt wheels 10. The two circular felt wheels 10 are respectively fixed on the first pliers rod and the second pliers rod; when the first pliers rod and the second pliers rod are closed, the two circular felt wheels 10 are driven to approach and squeeze each other, so as to wipe off the coating layer on the optical fiber through the two circular felt wheels 10.

[0054] Exemplarily, a threaded post is respectively arranged on the first pliers rod and the second pliers rod, and the two circular felt wheels 10 are respectively fixed on the two threaded posts, and the circular felt wheels 10 are fixed through the nuts on the outer sides of the circular felt wheels 10, so that the circular felt wheels 10 can be conveniently replaced.

[0055] After the circular felt wheels 10 are dipped in alcohol, when the first pliers rod and the second pliers rod are closed, the two circular felt wheels 10 are driven to close and clamp the optical fiber, and the remaining coating layer on the optical fiber can be wiped off through the two circular felt wheels 10.

[0056] Through the above settings, it is convenient to remove the remaining coating layer on the optical fiber, and the functionality of the pigtail stripping pliers is improved.

[0057] In some embodiments, a first shearing part is arranged on the outer side surface of the pliers handle of the first pliers rod, and a second shearing part is arranged at a position close to the first shearing part on the outer side surface of the pliers handle of the second pliers rod. When the first pliers rod and the second pliers rod are closed, the first shearing part and the second shearing part jointly form a fourth jaw 11, and the fourth jaw 11 is a cutting opening.

[0058] Exemplarily, both the first shearing part and the second shearing part are U-shaped notches. The width of the U-shaped notch is 2.4 mm, and the height is 3.5 mm.

[0059] Exemplarily, when the first pliers rod and the second pliers rod are fully opened, the positions of the first shearing part and the second shearing part are aligned with each other. When it is necessary to cut the strengthening steel wire outside the outdoor skin wire, the strengthening steel wire is passed through the first shearing part and the second shearing part. At this time, the staff closes the first pliers rod and the second pliers rod, and the first shearing part and the second shearing part are misaligned to form the fourth jaw 11, and the strengthening steel wire is cut through the fourth jaw 11.

[0060] Through the above settings, the strengthening steel wire can be cut, improving the functionality of the fiber optic cable stripping pliers.

[0061] In some embodiments, as Figure 1 and Figure 2 shown, the fiber optic cable stripping pliers further include a limit adjusting member 12. The limit adjusting member 12 is fixed on the pliers handle of the second pliers rod or the first pliers rod. One side of the limit adjusting member 12 opposite to the pliers handle of the first pliers rod or the second pliers rod has an adjusting portion; the length of the adjusting portion extending out of the limit adjusting member 12 is adjustable, so as to adjust the sizes of the multiple jaws formed when the pliers head of the first pliers rod and the pliers head of the second pliers rod are closed through the adjusting portion.

[0062] It should be noted that when the limit adjusting member 12 is fixed on the pliers handle of the second pliers rod, the adjusting portion is located on the side of the limit adjusting member 12 opposite to the pliers handle of the first pliers rod; when the limit adjusting member 12 is fixed on the pliers handle of the first pliers rod, the adjusting portion is located on the side of the limit adjusting member 12 opposite to the pliers handle of the second pliers rod.

[0063] Exemplarily, the adjusting portion can be a screw screwed into the limit adjusting member 12. By adjusting the size of the part of the screw screwed into the limit adjusting member 12, the size of the part of the screw extending out of the limit adjusting member 12 can be adjusted.

[0064] As Figure 1 shown, when the first pliers rod and the second pliers rod are closed, the adjusting portion of the limit adjusting member 12 fixed on the pliers handle of the second pliers rod abuts against the pliers handle of the first pliers rod, thereby limiting the distance between the pliers handles of the first pliers rod and the second pliers rod when they are closed, and also limiting the sizes of the multiple jaws formed when the pliers heads of the first pliers rod and the second pliers rod are closed.

[0065] It can be understood that the longer the length of the adjusting part extending out of the limit adjusting part 12, the larger the distance between the handles of the first pliers rod and the second pliers rod when they are closed, and the larger the sizes of the multiple jaws formed when the jaws of the first pliers rod and the second pliers rod are closed; the shorter the length of the adjusting part extending out of the limit adjusting part 12, the smaller the distance between the handles of the first pliers rod and the second pliers rod when they are closed, and the smaller the sizes of the multiple jaws formed when the jaws of the first pliers rod and the second pliers rod are closed.

[0066] Through the above settings, the sizes of the multiple jaws formed when the jaws of the first pliers rod and the second pliers rod are closed can be finely adjusted, so that the sizes of the multiple jaws can be flexibly adjusted according to the size of the coating layer to be stripped during use, improving the versatility of the optical fiber stripping pliers.

[0067] In some embodiments, the optical fiber stripping pliers further include a protection part 13. The protection part 13 is rotatably arranged on the handle of the second pliers rod or the first pliers rod; when the first pliers rod and the second pliers rod are closed, the protection part 13 can be rotatably engaged with the handle of the first pliers rod or the second pliers rod after rotation, so that the first pliers rod and the second pliers rod are kept in a closed state.

[0068] It should be noted that when the protection part 13 is arranged on the handle of the second pliers rod, when the first pliers rod and the second pliers rod are closed, the protection part 13 can be rotatably engaged with the handle of the first pliers rod after rotation; when the protection part 13 is arranged on the handle of the first pliers rod, when the first pliers rod and the second pliers rod are closed, the protection part 13 can be rotatably engaged with the handle of the second pliers rod after rotation.

[0069] When the optical fiber stripping pliers are not needed, the first pliers rod and the second pliers rod can be kept in a closed state through the protection part 13, which is convenient for carrying the optical fiber stripping pliers.

[0070] In some embodiments, as Figure 1 and Figure 2 shown, the first pliers rod and the second pliers rod are hinged to each other through a rivet 14. A first mounting hole is formed at a position of the handle of the first pliers rod close to the rivet 14, and a second mounting hole is formed at a position of the handle of the second pliers rod close to the rivet 14. The first mounting hole and the second mounting hole are aligned with each other. The optical fiber stripping pliers further include a return spring 15, and the return spring 15 is arranged in the first mounting hole and the second mounting hole. One end of the return spring 15 abuts against the first pliers rod, and the other end abuts against the second pliers rod, and is used to reset the first pliers rod and the second pliers rod from the closed state to the open state.

[0071] Exemplarily, the return spring 15 is a common compression spring.

[0072] When the staff closes the pliers handles of the first pliers rod and the second pliers rod, the reset spring 15 will be compressed. When the pliers handles of the first pliers rod and the second pliers rod are released, the elastic force of the reset spring 15 causes the first pliers rod and the second pliers rod to reset from the closed state to the open state.

[0073] Through the above settings, it is convenient to install the reset spring 15, avoid the reset spring 15 from falling off, and enable the first pliers rod and the second pliers rod of the fiber optic cable stripping pliers to have the function of automatic reset, improving the operation convenience of the fiber optic cable stripping pliers.

[0074] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various variations and improvements can be made without departing from the spirit and essence of the present invention, and these variations and improvements are also regarded as the protection scope of the present invention.
