The invention relates to the field of vehicle-mounted jacks, in particular to a multifunctional jack. The multifunctional jack comprises a lifting mechanism and a driving mechanism for enabling the lifting mechanism to rise and fall, wherein the driving mechanism comprises a supporting assembly, a threaded rod connected to the supporting assembly in a threaded mode, a first force application assembly and a second force application assembly; and the first force application assembly comprises a connecting rod fixedly connected to the threaded rod and a hexagonal head connected to the connecting rod, the connecting rod and the threaded rod are coaxially arranged, and the second force application assembly comprises a force application rod connected to the connecting rod. During working, a drill bit of an electric drill is embedded into the hexagonal head, the electric drill drives the hexagonal head to rotate around the axis of the hexagonal head, the hexagonal head drives the connecting rod to rotate, the connecting rod drives the threaded rod to rotate, the threaded rod moves upwards relative to the supporting assembly, and the threaded rod drives the lifting mechanism to move upwards; and meanwhile, an operator can hold the force application rod by hand to drive the connecting rod to rotate, and thus a manual operation mode and an electric operation mode are available.
