The invention discloses a multi-degree-of-freedom flexible lifting appliance which comprises a rotary table, a rotary speed reducer, a rotary body, a cross beam, a first electric push rod, a telescopic arm, a second electric push rod, a direct-current servo all-in-one machine and a lifting rod. The hydraulic motor and the rotary speed reducer drive the rotary body to perform 360-degree full rotation relative to the rotary table; the rotary body is hinged to the cross beam, and two turn-back type first electric push rods are connected between the rotary body and the cross beam and drive the cross beam to longitudinally swing by +/-10 degrees relative to the rotary body; the telescopic arms are installed at the two ends of the cross beam, two second electric push rods are connected between the cross beam and the telescopic arms, and the second electric push rods drive the telescopic arms to move up and down along guide rails on the cross beam; the direct-current servo all-in-one machine is installed on the telescopic arm and controls rotation of the lifting rod so that the lifting rod can be locked to a lifted object or unlocked from the lifted object. The lifting appliance has the advantages of multiple degrees of freedom, flexible action, compact structure and high lifting precision.
