The pressing plate 101 is pressed downward, the pressing plate 101 rotates along the rotating member, the door-shaped member 109 slides along the guide plate, the optical fiber fixing sleeve 202 is fixed in the door-shaped member 109, and the free end of the pressing plate 101 is locked by the limiting mechanism.

[0027] In this embodiment, if Figure 1 As shown, the limiting mechanism includes a fixed section 106 arranged at the upper end of the junction box 100, an iron core 107 extending toward the pressing plate 101 is slidably provided in the fixed section 106, a guiding inclined surface is provided at the end of the iron core 107 close to the pressing plate 101, a tail rod 104 is provided at the end of the iron core 107 away from the pressing plate 101, and the tail rod 104 is connected to the fixed section 106 through a spring 105.
