Embodiment 2:

The difference from the first embodiment is that, as shown in FIGS. 1-3 and 5 , the protective cover 4 is composed of a protective tube 41 and a plurality of No. 1 arc-shaped elastic pieces 42 ; the outer ring of the protective tube 41 is provided with The thread groove matched with the screw cap 5; each of the No. 1 arc-shaped elastic pieces 42 is respectively connected to the end surface of the protection tube 41, and forms an aperture with the same size as the inner diameter of the protection tube 41, and the adjacent No. 1 arc-shaped elastic pieces Adjustment holes 43 are respectively formed between 42 .

When the outer diameter of the optical fiber 3 used is smaller than the inner diameter of the protection tube 41, since the inner diameter of the protection tube 41 is larger than the outer diameter of the optical fiber 3, the passage of the optical fiber 3 can be facilitated without causing damage to the optical fiber 3; When screwing the screw cap 5 in, the width of the inner space of the screw groove gradually decreases from the outside to the inside. The outer diameters of the rings are the same, so the No. 1 arc shrapnel 42 does not generate a force to move toward the side close to the outer ring of the optical fiber 3. Since the thread groove matched with the screw cap 5 is arranged on the outer ring of the protection tube 41, In order to form a threaded connection, as the screw cap 5 continues to work, when it is located in the area of multiple No. 1 arc-shaped shrapnel 42, the inner wall of the screw cap 5 squeezes the No. 1 arc-shaped shrapnel 42, so that the No. 1 arc-shaped shrapnel 42 is squeezed. 42 drives the pressing block 61 to move to the side close to the outer ring of the optical fiber 3 to lock the position of the optical fiber 3, and the screw cap 5 does not rotate, but the No. 1 arc shrapnel 42 will be on the side away from the optical fiber 3 The groove marks are left, which increases the frictional force between the No. 1 arc-shaped shrapnel 42 and the inner wall of the screw cap 5, and increases the difficulty of separating the screw cap 5 from the multiple No. 1 arc-shaped shrapnel 42;

When the front end of the screw cap 5 reaches the position of the protection tube 41, the screw cap 5 fits into the threaded groove on the outer ring of the protection tube 41 to form a threaded connection, which further prevents the screw cap 5 from detaching from the protection tube 41, thereby ensuring the inner wall of the screw cap 5. Squeeze the multiple No. 1 arc-shaped elastic pieces 42 to ensure that the pressing block 61 fits the outer ring of the optical fiber 3, so as to realize the locking of the position of the optical fiber 3, so as to prevent the position of the optical fiber 3 from moving due to the action of external force, resulting in The fusion joint between the optical fiber 3 and the pigtail in the communication body 1 is broken, thereby ensuring the stability of the optical fiber 3 communication.
