A universal mounting apparatus formed of a device cradle that is configured with a base plate having a device mounting surface with an integral stop structure adjacent to a first end thereof and projected thereabove, and a linear drive channel arranged along a first axis thereof. The universal mounting apparatus including a clamping mechanism having a linear drive shaft structured to slidingly engage the linear drive channel with a movable clamp structure projected above the device mounting surface adjacent to a second end of the base plate, the movable clamp structure has clamping surfaces inclined toward the device mounting surface and the integral stop structure projected thereabove. A spring is coupled for biasing the movable clamp structure toward the integral stop structure along the first axis.
