The invention discloses an electric spiral following jack, and relates to the technical field of building (structure) displacement transformation. The electric spiral following jack specifically comprises a base plate, an outer cylinder and an inner cylinder are coaxially arranged on the base plate, the outer cylinder is fixedly connected with the base plate, and the inner cylinder is in threadedconnection with the outer cylinder. A driving unit used for driving the inner cylinder to rotate is fixedly arranged on part, located in the inner cylinder, of the base plate. The driving unit comprises a mounting bracket fixedly arranged on the base plate, a driving motor is fixedly arranged in the mounting bracket, and a driving arm used for driving the inner cylinder to rotate is fixedly installed on a power output shaft of the driving motor. An unbalance loading resistant spherical hinge is arranged at the upper end of the inner cylinder. The jack is simple and compact in structure, smallin size and convenient to install and use. Meanwhile, the invention further provides a control method of the electric spiral following jack. By means of the control method, it can be guaranteed that the jacking end of the jack always abuts against a jacked building.
