Abstract: The present invention relates to a device for retrieving waste deposits and, more particularly, animal excrement and the like. The device includes an outer tubular shaft having a handle portion formed in the shape of the handle of a walking cane. An inner shaft is concentrically disposed within said outer shaft and is moveable longitudinally with respect thereto. Such longitudinal movement of the inner shaft causes a tension spring to bear against a normally-open hinge which, in the absence of circumferential force thereabout, will exhibit its normally-open position. Longitudinal movement of the inner shaft away from the handle will cause said tension spring to bear against the hinge thus permitting said hinge to open selectably as may be desired. After opening, a throwaway box is attached to the fingers of the hinge and, through an upper movement of the inner shaft, the retrieval of an animal deposit is achieved.
