The invention discloses a ceiling smart home mounting machine. The ceiling smart home mounting machine is mainly composed of a bottom plate part, a first-stage mechanism, a second-stage mechanism, a third-stage mechanism, a fourth-stage mechanism and a rotating mechanism. When the machine is used, wheels are used for moving the machine to the position required to be drilled, during work state, thewheels can be separated from the ground, and the work state is more stable. The four stages of mechanisms are used for achieving ascending work, the rotating mechanism is used for achieving the actions of drill hole angle adjusting, drilling, and expansion bolt mounting, an ash collecting device achieves collection of ash generated by drilling, and cleaning is facilitated.
