Disclosed is a rotating guiding device. The rotating guiding device comprises a rotating shaft, a first non-rotating body, a second non-rotating body and a guiding driving mechanism, wherein the rotating shaft rotates to drive a tool head and comprises at least one steerable part; the first non-rotating body and the second non-rotating body are each generally in a non-rotating state relative to the rotating shaft in the circumferential direction when the rotating shaft rotates to drive the tool head; and the guiding driving mechanism is connected with the first non-rotating body and the secondnon-rotating body and suitable for producing driving force generally in the axial direction to change the opposite direction between the first non-rotating body and the second non-rotating body, so that the direction of the tool head is changed.
