The invention relates to a multifunctional manpower machine basic part, a thrust rod, a pushing and pulling belt and accessories thereof. The basic part comprises a running wheel axle (2) arranged on a single frame (3), a running wheel (5) provided with a driving gear (6) at the end part, an armrest cross-rod (10) fixed tightly on an armrest straight rod (9), a thrust straight rod (11), a front-movable vertical rod (1), a back-movable vertical rod (12), a frame hook (2), a front suspension arm shaft (4), a back suspension arm shaft (8), etc. More than ten kinds of various functional mechanisms, tools and work parts are arranged on the suspension arm shafts and movable vertical rod in a module manner and each kind is provided with different specifications, functions and capabilities so as to lead a user to select parts individually for the mutual coordination without interruption. Particularly, the cooperation between the thrust rod and pushing belt changes the prior manner that hands and arms generate thrust so as to lead the abdomen to get thrust; and the shoulders generate pulling force so as to lead the waist to get pulling force, thereby saving force under the same work load. With a support connecting part, an operator can hold the machine with one hand and also can push the machine to move forward.
