An adjustable mounting device includes a base, first and second linearly displaceable support units, and first and second tiltable support units. The first linearly displaceable support unit is mounted movably on the base, and is operable to move along a first axis relative to the base. The first tiltable support unit is mounted pivotally to the first linearly displaceable support unit, and is operable to pivot about a second axis relative to the base. The second linearly displaceable support unit is mounted movably on the first tiltable support unit, and is operable to move along the second axis relative to the base. The second tiltable support unit is mounted pivotally to the second linearly displaceable support unit, and is operable to pivot about the first axis relative to the base.
