Referring to fig. 2 and 3, on the basis, at least one linkage plate 51 extending towards the tail direction of the connecting body 1 is fixedly connected to the lock sleeve 5, a driving column 52 extending outwards and penetrating through the side face of the connecting body 1 is arranged at one end, far away from the lock sleeve 5, of the linkage plate 51, the driving column 52 and the linkage plate 51 are reinforced through a reinforcing piece 53 connected with each other, an abdicating area 11 extending towards the end part and allowing the driving column 52 to penetrate is arranged at one side of the connecting body 1, and when the lock sleeve 5 slides on the splicing core 2, the driving column 52 connected to the lock sleeve 5 is synchronously driven to synchronously slide in the abdicating area 11. The both sides of rotating flip 3 have the connecting plate 31 that extends to the both sides of connecting body 1, connecting body 1 is last to be provided with the rotation post 12 of wearing to locate in connecting plate 31 and to connect in order to realize connecting plate 31 and connect for connecting body 1's rotation, one side that just is located rotation post 12 on connecting plate 31 is provided with the arc wall 32 that is used for supplying drive post 52 to wear to establish, rotating flip 3 and carrying out the pivoted in-process, drive post 52 can receive the spacing of arc wall 32 and carry out corresponding sliding motion in stepping down region 11, thereby drive the relative continuous core 2 emergence motion that the lock sleeve 5 corresponds. In addition, in order to ensure the structural strength of the linkage plate 51, a reinforcing plate 54 is connected between the linkage plates 51 on the two sides, and the reinforcing plate 54 is positioned in the outer circumferential direction of the splicing core 2.

In this embodiment, when the rotating flip 3 is closed and covered on the connecting body 1, the driving column 52 is gradually approached to the end of the optical fiber connector by the driving guide of the arc-shaped slot 32, whereas when the rotating flip 3 is turned to be opened, the driving column 52 is gradually approached to the position of the rotating column 12 by the driving guide of the arc-shaped slot 32.
