The invention relates to the technical field of mechanical oil extraction, and belongs to a novel sucker rod centralizing and paraffin scrapping device. The sucker rod centralizing and paraffin scrapping device is designed for effectively solving the problems that a sucker rod column is vibrated, a sucker rod tube is abraded, and paraffin is deposited on the inner wall of an oil tube. An upper central pipe (1) and an upper centralizing block (2) are cast together, a lower central pipe (3) and a lower centralizing block (4) are cast together, and the upper central pipe (1) is connected with the lower central pipe (3) through a locking block (7) and a locking groove (5). The sucker rod centralizing and paraffin scrapping device is mainly used for rod pumped wells of an oil field, and has the advantages of being low in cost, rapid and convenient to install, good in paraffin scrapping effect, not prone to playing in the axial direction, small in resistance to a sucker rod and oil and the like.
