The invention discloses a shiftable mechanical jack comprising a shift transmission mechanism and a lifting mechanism. The shift transmission mechanism is mounted on one side of the lifting mechanism and comprises a mounting shell, a first transmission rod, a second transmission rod and a rocker; the lifting mechanism comprises a lifting member, a first bevel gear, a second bevel gear, a lifting screw, an upper screw nut and a bottom plate; the mounting shell is mounted on one side of the lifting member; a support plate is mounted in the lifting member; the support plate is provided with a gear seat; the second bevel gear is mounted on the gear seat; the first bevel gear is mounted on the first transmission rod; the first bevel gear and the second bevel gear are mounted in a vertical meshing manner. The shiftable mechanical jack has the advantages that lifting speed of a container can be well controlled, handling the container is easier, less force is required by the rocker during handling, equipment structure is simple, stability is good, the lifting screw is high in strength, and the service life is longer.
