The invention relates to the field of cylinders, and discloses a multi-shaft combined cylinder comprising a cylinder body, nozzles, pistons, piston rods, returning springs, thimbles, adapting blocks, a guide tube and a gasket. The multi-shaft combined cylinder has the advantages that a cylinder is capable of achieving the effect of multiple shafts moving independently, axial distances among the shafts are further decreased, and the multi-shaft combined cylinder is particularly adaptive to multi-point independent moving mechanisms in small space environment.
