1. A rotation mechanism for an umbrella, comprising:
a hollow vertical column having a through hole;
a rotating shaft having a peripheral wall for a rope to wrap onto, rotatably disposed inside the through hole of the column;
a ratchet sleeved around the rotating shaft;
a magnet block; and
a pressing assembly;
wherein,
the ratchet has two side surfaces and a plurality of ratchet teeth on a periphery of the ratchet;
the column has a limiting room opening towards the ratchet teeth for receiving the magnet block;
the magnet block is movably located inside the limiting room, and has a magnetic attraction surface capable of being attached to the ratchet teeth;
when the rotating shaft rotates in a first direction, the magnet block separates from the ratchet teeth;
when the rotating shaft rotates in a second direction, the magnet block is attached and magnetically attracted to the ratchet teeth, so as to limit the rotation of the ratchet in the second direction;
the pressing assembly is connected to the rotating shaft and presses against the two side surfaces of the ratchet, so as to allow the ratchet to rotate with the rotating shaft when the rotating shaft rotates in the first direction, and the magnet block stops the ratchet from rotating when the rotating shaft rotates in the second direction.
