The invention provides a driving control mechanism of a screw elevator, and belongs to the technical field of elevators. The driving control mechanism comprises a screw and a thread bushing matched with the screw, a sleeve is rotationally connected outside the thread bushing, and a mounting cavity is formed between the middle of the sleeve and the inner wall of the thread bushing; a rotor locatedin the mounting cavity is connected to the thread bushing through a spline, a plurality of permanent magnet strips are arranged on the rotor, and a plurality of stator iron cores evenly distributed inthe circumferential direction are arranged on the inner wall of the sleeve; each stator iron core is wound with an electrified coil and located in the middle of the sleeve, a first reset spring is connected between the upper end of the rotor and the thread bushing, a second reset spring is connected between the lower end of the rotor and the thread bushing, and the sleeve and the guide rail are matched to longitudinally slide under the condition that rotation of the sleeve is limited. The device has the advantages of being simple in structure, capable of driving the screw to rotate or tendingto stop the screw and the like.
