1. A wheeled carrying apparatus comprising:
a standing frame and a handle frame pivotally coupled to each other, the handle frame being rotatable relative to the standing frame between a first position and a second position of different inclinations;
a wheel mount carrying a wheel and pivotally connected with the standing frame, the wheel being rotatable relative to the wheel mount about a wheel axis;
a locking assembly including a wheel mount latch connected with the standing frame, the wheel mount latch being adapted to engage and thereby rotationally lock the wheel mount with respect to the standing frame, and to disengage and thereby unlock the wheel mount so that the wheel mount is rotatable relative to the standing frame for changing an orientation of the wheel axis;
an actuating assembly coupling the wheel mount latch to the handle frame so that the wheel mount latch is movable to engage and disengage the wheel mount in response to a rotation of the handle frame; and
a release mechanism including an operating part, and a cable assembly coupling the operating part to the actuating assembly, wherein the cable assembly includes a flexible part configured to stretch or loosen as the handle frame rotates between the first position and the second position, the operating part being operable to cause the wheel mount latch to disengage from the wheel mount when the handle frame is in the first position.
