Description

technical field [0001] The invention relates to a transport machine capable of climbing stairs to transport articles, in particular to a multifunctional trolley capable of climbing stairs composed of mechanical mechanisms. Background technique [0002] With the continuous prosperity and development of the social economy, there are more and more residents living in buildings. Most of the current residential buildings are 6-7 floors, and there are no elevators. When transporting objects, it will be very laborious or require two people to lift them up, which is labor-intensive and time-consuming. At the same time, collisions will occur if there is a slight carelessness during transportation, and the objects will be damaged if they are not close, and sometimes the personal safety of residents will be threatened. It is especially inconvenient for households lacking labor force in the family. In addition, when we go out, we will inevitably encounter stairs when we carry bulky lug...
