Namely: the connecting part 101a is provided with an external thread, the connecting section 201 is sleeved on the periphery of the connecting seat 100, and the inner side wall of the connecting section is provided with an internal thread matched with the external thread; the connecting section 201 and the connecting part 101a are detachably connected through matching of threads.

Further, the rear end of the tailstock 101 is provided with a tapered surface 101c, and the compressing assembly 200 further includes an extruding section 202 connected to the connecting section 201 and located at the rear end thereof, wherein the connecting section 201 and the extruding section 202 are integrally formed. The extruding section 202 may be a tapered tube having an inner diameter gradually decreasing from the end engaged with the connecting section 201 toward the rear. When the connecting section 201 is connected to the connecting section 101a of the tailstock 101, the pressing section 202 can press the tapered surface 101 c. Therefore, the reinforcing wire 603 introduced between the connecting section 201 and the connecting section 101a can be sandwiched between the pressing section 202 and the tapered surface 101c, so that double fixation of the reinforcing wire 603 is realized, and the tensile resistance thereof exceeds 50N.

The cantilever 102a is a strip-shaped structure which is integrally formed on the rear end of the tailstock 101 and extends backwards along the longitudinal direction, and the cross section of the cantilever is preferably an arc-shaped bent plate which protrudes outwards; the clasps 102b are preferably fixed to a ring structure on the end of the cantilever 102 a. The sheath 604 can be embedded into the ring of the hoop 102b to realize initial fixation, so that a constructor can ensure accurate positioning of the bare fiber 601 in the fastening process of the bare fiber 601 and the tight cladding layer 602 and also protect the bare fiber 601 from being pulled. In addition, the fixing component 300 is detachably connected to the clasping ring 102b and can be clamped and clamped together with the clasping ring 102b to form a longitudinally through fixing position G.

Locking element 301 may be a protruding structure, a knife-like structure, or a pointed structure inside of fixation assembly 300 that is capable of extending partially into fixation site G. Thus, when the outer skin 604 is embedded in the clasping ring 102b and is covered on the clasping ring 102b by the fixing component 300, the locking component 301 inside the fixing component 300 can partially cut or penetrate into the outer skin 604 and realize the final fixing of the outer skin 604 under the constraint of the periphery.

Further, the fixing assembly 300 further includes an insertion section 302 engaged with the opening 102b-1 and a jaw 303 fixed to an end of the insertion section 302. The insertion section 302 is a structure capable of being inserted into the opening 102b-1 of the hoop 102b, and has a complementary structure, while the claw 303 has a bayonet 303a fitted to the outer skin 604, and the locking member 301 is disposed on the inner side surface of the insertion section 302 and/or the claw 303.

Preferably, the two ends of the embedding section 302 are respectively provided with a claw 303, and the distance between the two claws 303 is matched with the longitudinal length of the clasping ring 102 b. Therefore, when the inserting section 302 is inserted into the opening 102b-1, the claws 303 at both ends thereof can be respectively and exactly defined at the front and rear ends of the hoop 102b, and the bayonets 303a of both claws 303 can be clamped at the periphery of the outer skin 604, so as to realize the final fixation of the outer skin 604.

Preferably, the locking member 301 is an outer convex blade-like structure disposed on the inner side surface of the bayonet 303a, and is integrally formed with the claw 303. When the claw 303 is clamped on the periphery of the outer skin 604, the locking member 301 can be cut into the outer skin 604 to limit the longitudinal sliding of the outer skin 604, so that the outer skin 604 is fixed.

Further, the rear portion of the compressing assembly 200 is provided with a bell mouth 203, and the flexible cantilever 102a passes through the bell mouth 203 and can swing within the bell mouth 203 to a certain extent.

Further, the flexible optical cable fastening device further includes a tail sleeve 400, which is used for protecting the optical cable at the tail of the pressing component 200 and also can play a role in restraining and fixing the matching connection between the fixing component 300 and the surrounding ring 102 b. Specifically, the tail sleeve 400 is internally provided with a limiting cavity 401, and two ends of the limiting cavity are through; after the fixing assembly 300 is detachably connected to the positioning member 102, the tail sleeve 400 can be pushed in and sleeved on the positioning member 102 and the periphery of the fixing assembly 300 through the limiting chamber 401, so that the outer skin 604 and the positioning member 102 are firmly fixed; furthermore, the utility model discloses can stretch out the length of bail front end through control crust 604, guarantee that crust 604 tensile drags the ability, avoid indoor optical cable 600 when cold and hot temperature variation, the chucking power that the crust 604 hard and soft brought changes.

Further, a wire gathering groove 402 is arranged at the front end of the tail sleeve 400, and the wire gathering groove 402 is opened outwards. The exposed reinforcing wire 603 is constrained in the wire gathering groove 402 after being pulled, and has a positioning effect on the position of the reinforcing wire 603; in addition, the wire gathering groove 402 can improve the torsion resistance of the connecting section 201 in the rotating process, and avoids the extra damage of the optical cable caused by the winding of the reinforcing wire 603 and the optical cable due to the rotation and tightening of the connecting section 201.

Further, the tail sleeve 400 is provided with an observation window 403 which can be communicated with the limiting chamber 401. The viewing window 403 is a through-going feature on the boot 400 and is directly opposite any section of the upjacket layer 602. After the optical cable is fixed by the constructor, the leakage detection red light in the bent optical cable can be checked through the observation window 403, and the leakage degree can be determined, so that the approximate bending degree of the tight cladding layer 602 and the fixing quality of the optical cable can be preliminarily judged. In another embodiment, the boot 400 is made of a transparent or translucent material, such as a conventional transparent plastic, a translucent PC material, etc., and can directly observe the light leakage inside the boot 400 instead of the observation window 403.

Further, a ring of anti-falling ring 404 is arranged at the front end of the inner side wall of the limiting chamber 401, and the inner diameter of the anti-falling ring 404 is smaller than the peripheral size of the fixing assembly 300, so that after the limiting chamber 401 is sleeved on the periphery of the fixing assembly 300 and the surrounding ring 102b, the anti-falling ring 404 can be placed on the front side surface of the clamping jaw 303, and the limiting of the tail sleeve 400 is realized, so that the tail sleeve cannot be released backwards.

Further, the maximum outer diameter of the tail sleeve 400 is not larger than the minimum inner diameter of the compression assembly 200, so that the tail sleeve 400 can pass through the interior of the compression assembly 200 without hindrance, and the problem of successive fiber passing of the compression assembly 200 and the tail sleeve 400 is not required to be considered when the indoor optical cable 600 is installed in a fiber passing mode.
