The housing 1 is provided with an axially extending accommodation cavity 5, and the side wall of the housing 1 is provided with an elastic buckle 6. The plug assembly 2 is arranged in the accommodation cavity 5 of the housing 1, and the plug assembly 2 comprises a plug 7 and a spring 8 sleeved on the plug 7. The cable core of the optical cable 27 is connected to the plug 7. The stopper 3 is connected to the rear end of the housing 1, and the front end of the stopper 3 is against the spring 8. The stopper 3 is provided with a through hole 9 in the middle, and the stopper 3 is provided with a first slot 10 in front of the through hole 9, and the stopper 3 is provided with a second slot 11 and a wire clamp 12 at the rear end of the through hole 9, and the first slot 10 and the second slot 11 are in opposite directions. The tail handle 4 is connected to the rear end of the stopper 3, and the tail handle 4 can retract the wire clamp 12 so that the wire clamp 12 is clamped on the optical cable 27.

[0025] Preferably, a dust cap 13 is provided at the front end of the ferrule 7, and a conical head 14 is provided at the front end of the dust cap 13. After the conical head 14 is provided at the front end of the dust cap 13, it is easier to pass the pipe when blowing the cable.
