The movement of the stop bar 26 will drive the L-shaped rod 25 fixed thereto to slide inside the L-shaped groove 24. The movement of the L-shaped rod 25 will drive the first screw 27 to slide inside the fixing block 28. At this time, the first threaded ring 29 can be rotated on the first screw 27. At this time, the extension distance of the stop bar 26 can be controlled by adjusting the position of the first threaded ring 29 on the first screw 27. At this time, the free end of the optical cable will be limited by the stop bar 26.
