1. A pivot joint comprising:
a first joining part, a second joining part and a coupling part pivotally connected with one another, the second joining part being disposed between the first joining part and the coupling part;
a latch carried with the second joining part and movable between a locking position where the latch is engaged with the coupling part to prevent rotation of the second joining part relative to the coupling part, and an unlocking position where the latch is disengaged from the coupling part for rotation of the second joining part relative to the coupling part; and
a linking mechanism configured to couple the latch to the first joining part so that a rotation of the first joining part relative to the second joining part in a first direction causes the latch to disengage from the coupling part, and a rotation of the first joining part relative to the second joining part in a second direction opposite to the first direction causes the latch to engage with the coupling part.
