Angle-adjustable mounting apparatus

An angle-adjustable mounting apparatus for mounting a second object to a first object, said angle-adjustable mounting apparatus comprising:

• a first mounting device to be coupled to the first object;
• a second mounting device to be coupled to the second object, said second mounting device being connected pivotally to said first mounting device and being pivotable relative to said first mounting device about a first axis;
• and
• a first pivot-control unit including a first component provided at said first mounting device and a second component provided at said second mounting device, said second component abutting against and being rotatable relative to said first component to enable said second mounting device to pivot relative to said first mounting device about the first axis, one of said first and second components being a plug component with a curved surface, and the other one of said first and second components being a socket component;
• said first pivot-control unit further including a first adjusting rod coupled to said second component and operable to drive said second component so that assembly of said second component and said second mounting device pivots relative to said first component,
• wherein said first mounting device includes:
• a first mounting part to be coupled to the first object;
• a second mounting part connected pivotally to said first mounting part and pivotable relative to said first mounting part about a second axis that is perpendicular to the first axis, said second mounting device being connected pivotally to said second mounting part;
• and
• a second pivot-control unit including a third component provided at said first mounting part and a fourth component provided at said second mounting part, said fourth component abutting against and being rotatable relative to said third component to enable said second mounting part to pivot relative to said first mounting part about the second axis,
• wherein said second pivot-control unit further includes a second adjusting rod coupled to said third component and operable to drive said third component so that assembly of said fourth component and said second mounting part pivots relative to said third component,
• wherein said second mounting device includes:
• a first connection part connected pivotally to said second mounting part;
• a second connection part to be connected to the second object and retained pivotally on said first connection part so as to be pivotable relative to said first connection part about a third axis perpendicular to the first and second axes;
• and
• a third pivot-control unit including
• an adjusting base provided on said second connection part and formed with a third threaded hole therethrough, said third threaded hole having a hole axis that is not parallel to the third axis, and
• a third adjusting rod which is a threaded rod coupled rotatably to said first connection part for rotation about a rod axis of said third adjusting rod, said third adjusting rod threadedly engaging said third threaded hole,
• wherein rotation of said third adjusting rod relative to said first connection part results in displacement of said adjusting base along said third adjusting rod and pivoting of said second connection part relative to said first connection part.
