A ceiling mount includes a base adapted to engage with one side of the ceiling, a core extending through the base to securely connect to the base and having a cylindrical body provided with at least one indentation, at least one arm selectively extending out of and movably received in the at least one indentation of the cylindrical body for engagement with the other side of the ceiling so as to provide a supporting force, at least one threaded bolt rotatably mounted in the cylindrical body and operably connected to the at least one arm to allow the at least one arm to extend out of and move relative to the cylindrical body in response to the rotational movement of the at least one threaded bolt and a stop to avoid the at least one arm from further extending.
