An electronically controlled full rotary clutch controller includes a drive assembly, an executive assembly and an auxiliary assembly. The device can have two working states: directional drilling and compound drilling. When compound drilling, drilling parameter information is obtained through the main control board, and the data is fed back to a ground processing system, which transmits a control signal to the main control board. The main control board controls a rotating motor, and pushes a screw sleeve and a push block shaft on a ball screw. The push block shaft pushes a push block radially, and a mandrel shell transmits torque to a roller shell through the push block. The roller shell and the mandrel shell rotate together to realize compound drilling. When directional drilling, the main control board reverses the rotary motor, the push block shaft pulls the push block radially, and the roller shell does not rotate.
