[0038] One end of the clamping plate 61 is installed with a connecting shaft 63, one end of the connecting shaft 63 is installed with a sliding sleeve 64, one side of the sliding sleeve 64 is installed with a scraper 65, the scraper 65 is used for scraping the outer surface of the fiber jumper, the upper end of the sliding sleeve 64 is also installed with a spray pipe 13, one end of the spray pipe 13 is connected with the upper end of the sliding sleeve 64, and the other end of the spray pipe 13 is connected with the upper end of the scraper 65.

[0039] According to Figure 1 , the fiber line and the optical jumper connector are placed at the upper end of the base 2, so that the fiber line and the optical jumper connector are located at the clamping groove 62, according to Figure 2As shown, the sliding connection shaft 63 is connected with the sliding sleeve 64, so that the sliding sleeve 64 drives the scraper 65 to approach the outer surface of the optical fiber wire, and then by rotating the two sliding sleeves 64, the sliding sleeve 64 drives the scraper 65 to rotate, so that the scraper 65 rotates to cut the outer surface of the optical fiber wire and the outer surface of the optical fiber connector, thereby forming a concave on the optical fiber wire and the optical fiber connector, then sliding the limiting ring between the optical fiber wire and the optical fiber connector, then injecting the glue through the spray pipe 13 to the outer surface of the optical fiber wire and the optical fiber connector, then by extruding the deformed limiting ring, so that the glue flows to the limiting ring and the optical fiber wire and the optical fiber connector, when the glue solidifies, and the connecting strength of the limiting ring and the optical fiber wire and the optical fiber connector is increased by the glue in the concave, thereby reducing the risk of separation and falling of the optical fiber wire and the optical fiber connector after long-term use.

[0040] Embodiment 2

[0041] This embodiment is an improvement based on embodiment 1, for details, please refer to Figures 1-3 The sliding sleeve 64 is slidably connected with the sliding bar 68, the sliding bar 68 penetrates the sliding sleeve 64, one side of the sliding bar 68 is connected with the scraper 65, and the outer surface of the sliding bar 68 is further provided with the first spring 12, one side of the first spring 12 is connected with the inner wall of the sliding sleeve 64;

[0042] One end of the clamping plate 61 is provided with the receiving cavity 67 for receiving the sliding sleeve 64;

[0044] One end of the receiving cavity 67 is provided with the sealing plate 66, and the sealing plate 66 and the clamping plate 61 are connected through the contraction spring.

[0045] According to Figure 2 and Figure 3As shown, when the connecting shaft 63 drives the sliding sleeve 64 to rotate, the adjusting device 9 at one end of the sliding strip 68 is in contact with the arc block 69, so that the sliding strip 68 and the scraper 65 are pressed by the arc block 69 to slide to one end. When the scraper 65 rotates around the axis of the connecting shaft 63, the scraper 65 can cut deeper into the outer rubber of the optical fiber cable and the optical connector joint. Then, the scraper 65 continues to swing to cut the rubber. At this time, the scraper 65 cuts a part of the rubber, but the cut rubber is not separated from the rubber. Then, when the adjusting device 9 is not in contact with the arc block 69, the first spring 12 pulls the sliding strip 68 and the scraper 65 to reset, so that the scraper 65 is separated from the cut rubber, thereby realizing that the outer surface of the optical connector joint and the optical fiber cable is cut to extend the rubber strip connected with the outer rubber.

[0047] It should be particularly pointed out that the inner diameter of the limiting ring is larger than the optical connector joint and the optical fiber cable, and the limiting ring is deformed to shrink by pressing, so that the limiting ring is attached to the outer surface of the optical connector joint and the optical fiber cable.

[0048] Embodiment 3

[0057] According to Figure 2 , the operator first passes the optical connector and the optical fiber line through the rotating plate 83, because one end of the rotating plate 83 is limited by the stop strip 84, so the optical connector and the optical fiber line will extrude the two rotating plates 83 to expand to both ends, so that the optical connector and the optical fiber line fall to the clamping groove 62, and are supported by another group of rotating plates 83, and the upper end of the optical connector and the optical fiber line is supported by the upper end rotating plate 83 in Figure 2 , so that the optical connector and the optical fiber line are extruded by the two groups of rotating plates 83, so that the optical connector and the optical fiber line are located in the middle of the clamping groove 62, so that the scraper 65 can accurately cut into the outer surface of the optical connector and the optical fiber line;

[0064] It should be particularly pointed out that the rubber is continuously transmitted to the second cavity 11 through the transmission hole 14, so that the one-way valve 16 is opened and closed to supplement the rubber to the first cavity 10.
