When the positioning ring 31 rotates, it will move in the front-to-back direction. The rear surface of the positioning ring 31 is provided with an annular groove 302. The inner wall of the annular groove 302 is slidably connected with a protrusion 33. When the positioning ring 31 moves back and forth, it will pull the protrusion 33 to move synchronously, but the protrusion 33 will not rotate synchronously with the positioning ring 31. The rear surface of the protrusion 33 is fixedly connected with a positioning block 32, and the positioning block 32 and the protrusion 33 will move synchronously. The positioning assembly also includes a positioning rod 34. The upper surface of the circular tube 1 is penetrated by and slidably connected with a connecting block 35. The left surface of the connecting block 35 is provided with an oblique groove 303. The lower surface of the connecting block 35 is fixedly connected with a clamping block 36 for clamping the optical fiber body 2, and the connecting block 35 and the clamping block 36 will move synchronously.

[0032] Reference Figure 1 - Figure 2 The protective component includes a front sleeve 41, which is sleeved on the front end of the outer wall of the circular tube 1, and a threaded tube 42 is fixedly connected to the rear surface of the front sleeve 41. A rear sleeve 43 is sleeved on the rear end of the outer wall of the circular tube 1. An annular protrusion is provided on the front side of the front sleeve 41 and the rear side of the rear sleeve 43. The inner wall of the annular protrusion fits the circular tube 1, and a sponge pad 44 is fixedly connected to the inner wall of the rear sleeve 43, so that the device has a certain pressure resistance and can play a buffering role.

[0033] Reference Figure 1 , Figure 3 , Figure 4The thread groove 301 is opened in the middle section of the outer wall of the round tube 1. The round tube 1 is thin in the middle and thick at both ends. The thread groove 301 is concentric with the positioning ring 31. The upper surface of the positioning ring 31 is lower than the upper surface of the outer wall of the two ends of the round tube 1. The positioning block 32 is slidably connected to the upper surface of the round tube 1 and slides in the front-back direction. The positioning block 32 is located in the middle section of the round tube 1. The left surface of the positioning rod 34 is fixedly connected to the rear end of the right surface of the positioning block 32. The positioning rod 34 is slidably connected to the inner wall of the inclined groove 303. When the positioning rod 34 slides, it will squeeze the inner wall of the inclined groove 303. 03 The front end is low and the rear end is high. When the positioning rod 34 moves backward, it will drive the connecting block 35 to move downward. When the positioning rod 34 moves forward, it will drive the connecting block 35 to move upward. The clamping block 36 is set to an arc shape. There are four groups of clamping blocks 36, connecting blocks 35, positioning rods 34, protrusions 33, and positioning blocks 32. The four groups of clamping blocks 36, connecting blocks 35, positioning rods 34, protrusions 33, and positioning blocks 32 are arranged in a circular array with the center of the positioning ring 31 as the origin. They can clamp the optical fiber body 2 from four different directions at the same time to ensure the stability of the clamping.

[0034] Reference Figure 1 - Figure 2 The optical fiber body 2 passes through the front surface of the front sleeve 41 , the optical fiber body 2 passes through the rear surface of the rear sleeve 43 , and the threaded tube 42 passes through and is threadedly connected to the front surface of the rear sleeve 43 .

[0035] Working principle: When the optical fiber body 2 needs to be hot-melt connected, first insert two sections of the optical fiber body 2, one section from the front side of the round tube 1, and the other section from the back side of the round tube 1.

[0036] When the optical fiber bodies 2 at both ends are in contact with the clamping block 36, the positioning ring 31 is rotated to move the positioning ring 31 backward. When the positioning ring 31 moves backward, it will squeeze the protrusion 33 to make it move backward synchronously. The protrusion 33 drives the positioning block 32 to move backward, and the positioning block 32 drives the positioning rod 34 to move backward. Since the front end of the inclined groove 303 is low and the rear end is high, the positioning rod 34 will squeeze the inner wall of the inclined groove 303 during the backward movement, thereby driving the connecting block 35 to move downward, and the connecting block 35 drives the clamping block 36 to move downward. The four groups of clamping blocks 36 can clamp and position the optical fiber body 2 from four different directions to ensure that the optical fiber body 2 remains stable during hot melting.

[0037] After the hot-melt connection of the optical fiber body 2 is completed, the front sleeve 41 is sleeved on the front end of the outer wall of the circular tube 1, and the rear sleeve 43 is sleeved on the rear end of the outer wall of the circular tube 1, and the threaded tube 42 is passed through and threadedly connected to the front surface of the rear sleeve 43 to complete the installation of the front sleeve 41 and the rear sleeve 43. When the device is squeezed by external force, the sponge pad 44 on the inner wall of the rear sleeve 43 gives the device a certain pressure resistance and can play a buffering role, thereby protecting the optical fiber body 2 that has been hot-melt connected and preventing the connection from being damaged by external force.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
