Control mechanism for switching moving and lifting functions of wheelchair

The invention discloses a control mechanism for switching moving and lifting functions of a wheelchair. The control mechanism for switching the moving and lifting functions of the wheelchair comprisesa center shaft, a tension line and two sets of chain transmission assemblies arranged on the center shaft in a bilateral symmetry mode, wherein the chain transmission assemblies are connected to supporting plates; and the two supporting plates are connected through the tension line. In each chain transmission assembly, one end of the supporting plate is buckled between a first meshing device andthe inner end of a second chain wheel and is connected with the center shaft; the second chain wheel and the first meshing device are relatively fixed and connected to the center shaft; a first chainwheel is in chain transmission connection with a third chain wheel through a chain, and the axis position is fixed through an external system; a second meshing device is arranged between the outer endof the third chain wheel an
