1. A floating-type on-water support apparatus comprising:
a ball in which a guide groove is formed along a circumferential surface thereof;
a floating unit including a floating part which floats on water and supports the ball so that the ball is rotatable; and
a support rod,
wherein a first end of the support rod is exposed above the water and a second end of the support rod is heavier than the first end so that the support rod stands vertically, passes through the circumferential surface, and is coupled to the ball,
wherein the floating unit further includes a restriction protrusion fitted into the guide groove to restrict the ball from being rotated about an axis of the support rod,
wherein the floating unit further includes a fixing member by which the restriction protrusion is installed on the floating part,
wherein the ball further includes a fixing groove formed in the guide groove at two sides of the ball to be perpendicular to a central axis of the support rod,
wherein the restriction protrusion is fixed to the fixing member to be movable toward or away from the fixing member in a radius direction of the ball so as to be fitted into the fixing groove.
