[0028] The present invention will be further described below with reference to the embodiments.

[0029] Please see Figures 1-6This utility model provides a fiber optic stripping tool that retains the coating layer, including a lower blade holder 1 and an upper blade holder 2. A hinge assembly 3 is connected between the lower blade holder 1 and the upper blade holder 2. The hinge assembly 3 includes a boss 31 fixedly connected to the upper side of the lower blade holder 1 and a clamping fork 32 fixedly connected to the lower side of the upper blade holder 2. A pin 33 is rotatably embedded in the boss 31, and the two ends of the pin 33 are fixedly connected to the two sides of the clamping fork 32 respectively.

[0030] Specifically, the lower blade holder 1 and the upper blade holder 2 can be opened and closed flexibly to adapt to the requirements of picking up and putting in optical fibers. When it is necessary to strip the optical fiber, the user can adjust the relative position of the lower blade holder 1 and the upper blade holder 2 by operating the hinge assembly 3 so that the blade holder can fit and fix the optical fiber, and then perform circumferential cutting and slitting operations.

[0031] Furthermore, a groove 34 is provided on the upper side of the boss 31, and a spring 35 is fixedly connected in the groove 34. The top of the spring 35 is in contact with the upper tool holder 2. A threaded hole with a hole is provided on one side of the boss 31. A fastening screw 36 is threadedly connected in the threaded hole with a hole. The fastening screw 36 is set to abut against the pin 33.

[0032] Specifically, the spring 35 can support the lower blade holder 1 and the upper blade holder 2 to open to the maximum angle, making it convenient to remove the optical fiber. After the lower blade holder 1 and the upper blade holder 2 are combined, the fastening screw 36 is tightened. The fastening screw 36 presses the pin 33 tightly, so that the lower blade holder 1 cannot rotate relative to the upper blade holder 2, keeping the two in a close fit state and ensuring that the optical fiber cutting process can proceed smoothly.

[0033] Furthermore, both the lower tool holder 1 and the upper tool holder 2 are provided with a connecting module 4 at the end away from the hinge position. The adjacent surfaces of the two connecting modules 4 are provided with a circumferential semicircular groove 41 and a slitting semicircular groove 42. Two guide pins 43 are fixedly connected to the connecting module 4 connected to the lower tool holder 1 on both sides of the circumferential semicircular groove 41 and the slitting semicircular groove 42. Two guide grooves 44 are provided on the connecting module 4 connected to the upper tool holder 2 on both sides of the circumferential semicircular groove 41 and the slitting semicircular groove 42, and the guide pins 43 correspond to the guide grooves 44.

[0034] Specifically, the cooperation of guide pin 43 and guide groove 44 can ensure that the combined module 4 of lower tool holder 1 and upper tool holder 2 maintains the correct relative position during circumferential cutting and slitting operations, and can provide positioning perpendicular to the tool holder movement direction to ensure that upper tool holder 2 is correctly aligned with lower tool holder 1.

[0035] Furthermore, the two circumferential semicircular grooves 41 correspond to each other, and the groove wall of the circumferential semicircular groove 41 is provided with a circumferential groove 411 perpendicular to it. The circumferential groove 411 is embedded with a cross blade 5 with adjustable extension length. The bottom of the circumferential groove 411 is provided with two cross blade semi-threads 412, and a cross blade adjusting screw 413 is threaded between the two cross blade semi-threads 412.

[0036] Specifically, by turning the cross blade adjusting screw 413, the length of the cross blade 5 extending out of the circumferential groove 411 can be adjusted to accommodate optical fiber protective layers of different thicknesses. It is worth noting that the length of the cross blade 5 extending out of the circumferential groove 411 should be at least half the thickness of the optical fiber protective layer, so that the optical fiber protective layer will not be damaged at once, and the optical fiber coating layer will not be damaged.

[0037] Furthermore, two transverse knife threaded holes 414 are provided on one side of the annular groove 411, and transverse knife clamping screws 415 are threaded into each of the transverse knife threaded holes 414.

[0038] Specifically, by tightening the cross blade clamping screw 415, it can be ensured that the cross blade 5 remains fixed during the circumferential cutting operation, preventing changes in the blade position caused by tool vibration or fiber movement, thereby ensuring the accuracy and reliability of the circumferential cutting process.

[0039] Furthermore, the two cutting semicircular grooves 42 correspond to each other, and a cutting groove 421 is provided in the center of the bottom of the groove wall of the cutting semicircular groove 42. A longitudinal blade 6 with an adjustable extension length is embedded in the cutting groove 421. Two longitudinal blade semi-threads 422 are provided on both sides of the cutting groove 421, and a longitudinal blade adjusting screw 423 is threaded between the two longitudinal blade semi-threads 422.

[0040] Specifically, the two pairs of longitudinal blade semi-threads 422 are located on the bottom and side of the slitting semi-circular groove 42, respectively. Tightening the longitudinal blade adjusting screw 423 on the bottom side can adjust the length of the longitudinal blade 6 extending out of the slitting groove 421 to accommodate optical fiber protective layers of different thicknesses. It is worth noting that the length of the longitudinal blade 6 extending out of the slitting groove 421 should be at least half the thickness of the optical fiber protective layer, so that the optical fiber protective layer will not be damaged at once and the optical fiber coating layer will not be damaged. Tightening the longitudinal blade adjusting screw 423 on the side side allows the longitudinal blade 6 to abut against the inner end wall of the slitting groove 421 to prevent the blade position from changing due to tool vibration or optical fiber movement, thereby ensuring the accuracy and reliability of the stripping process.

[0041] Furthermore, two longitudinal knife threaded holes 424 are provided on one side of the cutting groove 421, and longitudinal knife clamping screws 425 are threaded into each of the longitudinal knife threaded holes 424.

[0042] Specifically, tightening the longitudinal blade clamping screw 425 ensures that the longitudinal blade 6 remains fixed during operation, preventing changes in blade position due to tool vibration or fiber movement, thereby ensuring the accuracy and reliability of the peeling process.

[0043] Working principle:

[0044] In use, first place the optical fiber into the circumferential cutting semicircular groove 41, then close the lower blade holder 1 and the upper blade holder 2, and then rotate the optical fiber to circumferentially cut the optical fiber protective layer. Alternatively, place the optical fiber into the slitting semicircular groove 42, close the lower blade holder 1 and the upper blade holder 2, and then pull the optical fiber to cut the protective layer. After removing the optical fiber, tear the protective layer along the cut to expose the optical fiber core with a complete coating. By using both methods together, the process of removing the protective layer of half of the optical fiber can be completed. When cutting protective layers of different thicknesses, turning the cross blade adjusting screw 413 can adjust the extension of the cross blade 5 out of the circumferential cutting semicircular groove 41. After adjusting the length of the cross blade 5, tighten the cross blade clamping screw 415 to fully position the cross blade 5. Tighten the longitudinal blade adjusting screw 423 to adjust the extension length of the longitudinal blade 6 and ensure that the longitudinal blade 6 can abut against the inner end wall of the semi-circular groove 42. Then, tighten the longitudinal blade clamping screw 425 to fully position the longitudinal blade 6 and ensure that the fiber optic cutting process can proceed smoothly. It is worth noting that each clamping screw and adjusting screw mentioned above has a hexagonal countersunk groove on its end face, allowing the operator to rotate it with the help of tools.
