The invention discloses a linkage mechanism of a straight-shaft internal combustion engine. A balance shaft is arranged to be in a crankshaft shape; a straight shaft is positioned at the rear upper position of the balance shaft; a first linkage gear and a second linkage gear are coaxially and fixedly connected to one end face of the straight shaft and one end face of the balance shaft respectively; the first linkage gear and the second linkage gear are directly meshed and connected with an intermediate gear; four eccentric gears are arranged on the straight shaft in the axial direction; each crank part is assembled and connected with a balance shaft connecting part; each balance shaft connecting part is assembled and slidably connected with one end of each telescopic connecting rod; the ends, not connected with the balance shaft connecting parts, of the telescopic connecting rods are coaxially and fixedly connected with one ends of the piston connecting rods; and the side faces, close to the eccentric gears,
