An outer arc frame 12 is snap-connected to the outside of the inner arc frame 11. An active frame 13 is arranged inside the outer arc frame 12. A plurality of compression springs 14 are fixedly connected to the back side of the active frame 13 at equal intervals. The outer ends of the compression springs 14 are fixedly connected to the inner side of the outer arc frame 12. When the hoop mechanism 1 is clamped to the utility pole 18, it pushes the active frame 13 to make it close to the surface of the utility pole 18, achieving the effect of temporary clamping and preventing falling. The center of the outside of the active frame 13 is rotatably connected to a threaded rod 15. The threaded rod 15 is threadedly connected to the outer arc frame 12 and is fixedly connected to an adjustment knob 16 at the outer end. During use, the adjustment knob 16 can be manually rotated, which can then drive the threaded rod 15 to rotate. Then, by using the threaded connection between the threaded rod 15 and the outer arc frame 12 and the rotational connection with the active frame 13, the active frame 13 is driven to move, realizing the loosening and disassembly of the hoop mechanism 1 from the utility pole 18. This does not require the use of tools and the operation is simple and fast. A limit knob 17 is threadedly connected to the surface of the threaded rod 15 between the adjustment knob 16 and the outer arc frame 12, which is used to structurally limit the threaded rod 15 after the hoop mechanism 1 is fixed to the utility pole 18 to prevent rotation and loosening, and its structure has high installation stability.

[0026] The fiber optic splice box 2 includes a box body 21. A cable management mechanism 22 is fixedly connected inside the box body 21.

Card slots 225 are opened on both sides of the center of the winding frame 224 and at both ends of the cable groove 223. Permanent magnets 226 are embedded on both outer sides of the outer end of the cable management plate 222. Wedge-shaped platforms 227 are fixedly connected to both the upper and lower ends of the connecting frame 221. During use, the optical fibers introduced into the fiber optic splice box 2 are shunted by a splitter and then sequentially plugged and unplugged with the external household fiber optic connectors. Then, each group of plugged optical fiber bundles are sequentially wound around the winding frames 224 inside the cable grooves 223 of each cable management plate 222. The connectors are clamped in the card slots 225 inside the winding frame 224, and the optical fiber bundles connected on both sides are clamped in the card slots 225 at both ends of the cable groove 223. Thus, an independent unit layout and storage design for the optical fiber bundles in the fiber optic splice box 2 is achieved, realizing an orderly cable management and fixation of the optical fibers in the fiber optic splice box 2, facilitating subsequent maintenance and troubleshooting, thereby reducing the aerial operation time, reducing the safety hazards of operators, and improving the operation safety.
