[0025] The use method and advantages of the utility model: When the anti-loosening optical fiber connector is used, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, when using, the user places the device on a horizontal surface, picks up the optical fiber connector body 1, installs the protective shell 11 on the outer surface of the optical fiber connector body 1, then installs the mounting plate 13 on the upper and lower sides of the optical fiber connector body 1, then installs the connecting ring 14 on the rear side of the mounting plate 13, then installs the support rod 15 on the side end of the mounting plate 13 away from the connecting ring 14, installs two springs 16 inside the support rod 15, then installs the support rod 15 and the spring 16 into the mounting plate 13 along the side end opening of the mounting plate 13, then the user picks up the optical fiber connector body 1, and then installs the support rod 15 and the spring 16 into the mounting plate 13. The user then takes up the bolt 19 and uses the bolt 19 to connect the fixed splint 17 to the support rod 15. The user then takes up the support frame 2 and installs the first rotating gear 21 inside the support frame 2. The user then installs the threaded rotating rod 22 on both sides of the support frame 2. The user then installs the rotating handle 24 above the threaded rotating rod 22. The user then installs the second rotating gear 23 on the side end of the threaded rotating rod 22 and meshes the second rotating gear 23 with the first rotating gear 21. Then the user installs the support frame 2 to the rear position of the optical fiber connector body 1, and sets the connecting ring 14 on the outer surfaces of the two threaded rotating rods 22. When the user needs to use the device, the user first rotates the rotating handle 24, and the rotating handle 24 cooperates with the first rotating gear 21 to drive the two second rotating gears 23 to rotate, thereby driving the two threaded rotating rods 22 to rotate at the same time. At this time, the connecting ring 14 installed on the outer surface of the threaded rotating rod 22 can drive the two mounting plates 13 to move upward and downward, thereby adjusting the device opening to a suitable size, and then the user needs to connect The connected optical fiber is inserted into the connecting socket 12 opened at the side end of the optical fiber connector body 1, and then the fixing clamp 17 is pulled toward the front side of the optical fiber connector body 1. At this time, the support rod 15 of the fixing clamp 17 will be pulled outward from the inside of the mounting plate 13, and at the same time, the spring 16 will be squeezed in cooperation with the inner wall of the mounting plate 13. Then the user turns the rotating handle 24 again to make the mounting plate 13 close to the upper and lower sides of the optical fiber. As the fixing clamp 17 is released, the fixing clamp 17 will rebound under the cooperation of the spring 16 and the inner wall of the mounting plate 13, thereby pulling the optical fiber toward the optical fiber connector body 1, thereby preventing the optical fiber from loosening and falling off.
