Mounting mechanism and electronic device having the same

Abstract

A mechanism for mounting an electronic device to a ceiling or a wall includes a fixing seat with a mounting hole, a trigger button in the mounting hole, two clamping members slidably connected to the fixing seat, and two first elastic members. The clamping members abut opposing ends of the first positioning portion when the trigger button is at a first position, and the clamping members move toward each other by a resilient force when the trigger button moves toward the second position. In a second position two ends of the fixing member are clamped, thereby the electronic device is mounted firmly and stably to the fixing member. An electronic device having the mounting mechanism is also disclosed.
