Each side of a connecting rod big end is provided with two bolt holes and each side of a connecting rod cover is provided with two bolt holes. A positioning hole and a positioning pin are arranged between the two bolt holes on a subdivision surface of each side of the connecting rod big end, and a positioning hole and a positioning pin are arranged between the two bolt holes on a subdivision surface of each side of the connecting rod cover. One end of each positioning pin is in interference fit with each positioning hole in the connecting rod body big end. The positioning fin on an oilhole side is in a hollow sleeve structure, and the positioning pin on a non-oilhole side is in a solid prismatic structure. Inner protrude column surfaces of the bolt holes and outer protruded column surfaces of bolts are not needed, and sufficient gaps can be formed between t
