In addition, disassembly and replacement require relatively more operations, making it inconvenient for replacement and maintenance.

To resolve the foregoing problem, this application provides a rotation bracket, to rotate a communications device from an inner side of a wall to an outer side of the wall, to avoid construction on the outer side of the wall, thereby improving safety of mounting the communications device. Details are described as follows:.

Referring to <FIG>, an embodiment of a rotation bracket provided in this application includes:
