Orientation adjusting device for a satellite antenna

An orientation adjusting device, comprising:

• a base unit;
• a bracket unit coupled pivotally to said base unit, and including a pair of parallel plates;
• and
• an angle-adjusting mechanism for adjusting an angular position of said bracket unit relative to said base unit, said angle-adjusting mechanism including
• a first rotatable unit that includes a tubular member,
• a first pivot joint that interconnects said plates of said bracket unit and said tubular member of said first rotatable unit so as to permit rotation of said tubular member of said first rotatable unit relative to said bracket unit about a first horizontal axis,
• a second rotatable unit that is coupled pivotally to said base unit, and is pivotable relative to said base unit about a second horizontal axis parallel to the first horizontal axis, and
• a telescopic unit that interconnects said first and second rotatable units, and that is operable so as to vary the distance between the second and third horizontal axes, thereby adjusting the angular position of said bracket unit relative to said base unit,
• wherein said first pivot joint has an enlarged head that abuts against one of said plates of said bracket unit, and a shank that extends from said enlarged head and that is formed with a shoulder abutting against the other one of said plates of said bracket unit so as to fix the distance between said plates of said bracket unit, and
• wherein said tubular member of said first rotatable unit is sleeved on said shank of said first pivot joint.
