The invention relates to the technical field of lifters, and discloses a bottom frame lifting mechanism which comprises a manual pump, swing assemblies, push rod assemblies and walking assemblies. The power output end of the manual pump is connected with a first supporting base, the first supporting base is connected with a stand column, the bottom end of the manual pump is connected with a second supporting base, and the bottom end of the second supporting base is connected with first walking wheels. Each swing assembly comprises a first swing rod, a second swing rod, a first connecting shaft and a rotating shaft, wherein the first connecting shaft is connected to a bottom frame, the rotating shaft is sleeved with the first connecting shaft, the rotating shaft is rotatably connected to the first connecting shaft, one end of the first swing rod is rotatably connected to the rotating shaft, the other end of the first swing rod is fixedly connected to the first connecting shaft, and one end of the second swing rod is fixed to the first connecting shaft. One end of each push rod assembly is rotatably connected to the other end of the corresponding second swing rod, and the other end of each push rod assembly is connected with the corresponding walking assembly. The bottom frame lifting mechanism aims to achieve the purpose that a single-column lifter can move.
