Detailed Implementation

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes: Positioning cylinder 1, wherein the positioning cylinder 1 is a hollow cylindrical structure with one end open, and a positioning ring 2 is fixedly sleeved on the annular wall of the positioning cylinder 1, and the end of the connecting cylinder 3 is connected to the optical fiber. The connecting cylinder 3 is movably sleeved on the annular wall of the positioning cylinder 1, and the positioning ring 2 is used to limit the sleeve position of the connecting cylinder 3. The abutment rod 4, there are several abutment rods 4, and they are set at the same angle on the annular wall of the connecting cylinder 3 by the connecting component 5. The connecting cylinder 3 is fixed to the positioning cylinder 1 by the abutment rod 4 and the positioning ring 2. The buckle 6 consists of several buckles, each fixed to the left end of the abutment rod 4. The buckle 6 engages with the positioning ring 2, thereby restricting the position of the buckle 6. Each buckle 6 is provided with a buffer pad 16, which engages with the positioning ring 2 to ensure flexible contact between the buckle 6 and the positioning ring 2, thus preventing damage to the buckle 6 and the positioning ring 2. The adjusting cylinder 7 is threaded onto the annular wall of the connecting cylinder 3, and the annular wall of the adjusting cylinder 7 is provided with an inclined surface. The right end of the abutment rod 4 is slidably disposed on the inclined surface of the adjusting cylinder 7. The rotation of the abutment rod 4 is controlled by the adjusting cylinder 7. The annular wall of the adjusting cylinder 7 is fixed with protrusions 14 at equal angles, and the protrusions 14 are provided with rubber pads 17. The protrusions of the protrusions 14 facilitate the rotation of the adjusting cylinder 7. The right ends of several abutment rods 4 are screwed onto abutment shafts 15 by bearings. The abutment shafts 15 are slidably disposed on the inclined surface of the adjusting cylinder 7, so that the ends of the abutment rods 4 can roll on the inclined surface of the adjusting cylinder 7. The limiting ring 8 is fixedly sleeved on the right end of the connecting cylinder 3, and the adjusting cylinder 7 is engaged with the limiting ring 8 to restrict the movement position of the adjusting cylinder 7. Connection component 5 includes: The connecting ring 9 has several insert rods 10 fixed at equal angles on its right side surface. The insert rods 10 are movably inserted into the ring wall of the connecting cylinder 3. The abutment rod 4 is screwed onto the ring wall of the connecting ring 9 by a spring-loaded rotating rod. The connecting ring 9 is installed at the end of the connecting cylinder 3 by the positioning of the insert rods 10. The ring wall of the connecting ring 9 is provided with an abutment pad 13. The abutment pad 13 and the abutment rod 4 are set to abut against each other, so that the connecting ring 9 and the abutment rod 4 are in flexible contact. Nut 11, there are several nuts 11, and they are respectively threaded onto the right end of the insertion rod 10, and the nuts 11 are located on the right side wall of the connecting cylinder 3, and the insertion rod 10 is fixed in the connecting cylinder 3 by the nuts 11; The protective pad 12 consists of several pads, each of which is disposed on the nut 11. The protective pad 12 is configured to abut against the side wall of the connecting cylinder 3 to prevent the nut 11 from directly contacting the side wall of the connecting cylinder 3 and damaging the connecting cylinder 3.

[0018] When using this utility model, after the operator puts the connecting cylinder 3 on the positioning cylinder 1, the operator controls the rotation of the adjusting cylinder 7 through the protrusion 14. With the guiding effect of the inclined surface on the adjusting cylinder 7, and with the action of the spring-loaded rotating rod, the operator controls the rotation of the abutment rod 4. The abutment rod 4 drives the buckle 6 to rotate until the buckle 6 is locked on the positioning ring 2. At this time, the end of the adjusting cylinder 7 abuts against the limiting ring 8. With the self-locking characteristic of the thread, the position of the adjusting cylinder 7 is restricted, thereby fixing the connecting cylinder 3 on the positioning cylinder 1. This prevents the connection between the connecting cylinder 3 and the positioning cylinder 1 from loosening after a long time, which would affect the signal transmission of the optical fiber. Meanwhile, the operator periodically removes nut 11 and removes connecting ring 9 from connecting cylinder 3 to check the rotation of contact rod 4, so as to facilitate timely replacement of connecting ring 9 and contact rod 4.

[0019] Compared with the prior art, the beneficial effects of this utility model are: The rotation of the abutment rod 4 is controlled by the adjusting cylinder 7, so that the buckle 6 and the positioning ring 2 are locked together. Then, the self-locking characteristic of the thread is used to fix the position of the abutment rod 4, thereby limiting the position of the buckle 6 and connecting and fixing the positioning cylinder 1 and the connecting cylinder 3. The connecting component 5 is set up, and the connection state between the insert rod 10 and the connecting cylinder 3 is controlled by the nut 11. This facilitates the periodic replacement of the connecting ring 9 and the abutment rod 4, ensuring the rebound performance of the rebound rod on the abutment rod 4. The contact pad 13 is provided so that the contact rod 4 and the connecting ring 9 can make flexible contact, thus avoiding damage to the contact rod 4 and the connecting ring 9; An abutment shaft 15 is provided, which rolls on the inclined surface of the adjusting cylinder 7 to facilitate the movement of the abutment rod 4 on the adjusting cylinder 7.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
