The invention discloses a space coiling type stretching arm with the active pose adjusting capacity, and belongs to the technical field of spaceflight equipment and equipment. The device comprises a coiled stretching arm mechanism, a locking and releasing mechanism, a 3-RPS parallel mechanism, an electric linear sliding table and an electric rotating platform. The space coiling type stretching arm mechanism is fixed to the objective table through a fixing support, and the locking and releasing mechanism is installed between the objective table and the positioning table and is designed to be coupled with the 3-RPS parallel mechanism. The 3-RPS parallel mechanism is installed on the electric linear sliding table, and the electric linear sliding table is installed on the electric rotating platform through an adapter plate. The 3-RPS parallel mechanism is used for adjusting translation of the space stretching arm in the axis direction and rotation in the plane perpendicular to the axis of the arm body. The electric linear sliding table and the electric rotating platform are combined to be used for adjusting translation of the space stretching arm in the plane perpendicular to the axis of the arm body. According to the invention, the pose five-degree-of-freedom adjustability of the space coiling type extension arm after being unfolded can be realized, and the application range of the extension arm is widened.
