The utility model discloses a processing tool for realizing expansion fracture of connecting rods, which is mainly used for realizing expansion fracture of connecting rods of automobile engines. The technical scheme mainly includes that the tool comprises a clamping portion and a positioning stamping portion, a straight expansion sleeve, an inclined expansion sleeve and an expansion core are coaxially movably mounted on the surface, which is coaxial with two holes of a positioning block, of a base, and a small hole positioning central spindle is coaxially movably mounted on the surface, which is coaxial with a connecting rod small-end rod, of the base. During usage, the straight expansion sleeve, the inclined expansion sleeve, the expansion core and the small hole positioning central spindle are fixed onto a hydraulic device on the top of a machine tool, and the expansion core is wrapped by the straight expansion sleeve and the inclined expansion sleeve after the straight expansion sleeve, the inclined expans
