Wheeled carrying apparatus

A wheeled carrying apparatus comprising:

• a frame structure including a standing frame and a handle frame coupled to each other;
• a first wheel mount carrying a first wheel and pivotally connected with the standing frame, the first wheel being rotatable relative to the first wheel mount about a first wheel axis;
• a locking assembly including a first wheel mount latch movably connected with the standing frame, the first wheel mount latch having an elongate shape slidably received in a cavity provided in the standing frame, the first wheel mount latch being adapted to be engaged with the first wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and adapted to be disengaged from the first wheel mount to unlock the first wheel mount so that the first wheel mount is rotatable relative to the standing frame for changing an orientation of the first wheel axis;
• a second wheel mount carrying a second wheel and pivotally connected with the standing frame, the second wheel being rotatable relative to the second wheel mount about a second wheel axis, the second wheel mount is rotatable relative to the standing frame for changing an orientation of the second wheel axis;
• a linking part coupled to the first wheel mount latch;
• and
• a release mechanism being operable to cause the linking part to drive the first wheel mount latch to disengage from the first wheel mount, so that both the first wheel mount and the second wheel mount are rotatable relative to the standing frame.
