ABSTRACT:
A hand truck includes a frame, a telescopic handle pivotally connected with the frame, and a joint structure assembled between the frame and the handle. The frame is disposed with a collapsible wheel unit adjustable in position, and the handle and the frame can be bent and extended to a proper length and then fixed in position so that a user can push the hand truck with convenience. Further, the hand truck can be shaped alternately into a two-wheel vertical truck or a four-wheel platform hand truck.
