Abstract: A mounting device includes a housing, a sliding structure, and a switch structure. The housing includes two tracks, an elastic element including a blocking rib, and a first clamping element. The sliding structure is movably disposed in the tracks and includes a second clamping element and a reverse rib. The switch structure is movably disposed on the sliding structure and includes a forward rib. When the sliding structure is in the installed position, a support frame is fastened between the first clamping element and the second clamping element, and the blocking rib prevents the sliding structure moving relative to the housing. When the switch structure is moved in a detaching direction, the forward rib pushes the blocking rib away from the reverse rib, to allow the sliding structure to move in the detaching direction relative to the housing.
