The invention belongs to the field of undercarriage structure design, and particularly relates to an undercarriage frame linkage mechanism which comprises a supporting column, a fixed connecting rod, a rotary clamp, a stable buffer, an upper anti-torsion arm, a lower anti-torsion arm and a frame. The frame is perpendicular to the axis of the rotating shaft; the rotating shaft is hinged to the machine body; one end of the rotary clamp is hinged to a fixed connecting rod hinged to the machine body, the other end of the rotary clamp is hinged to a stable buffer, the other end of the stable buffer is hinged to the middle of an upper anti-torque arm, one end of the upper anti-torque arm is hinged to a supporting column, the other end of the upper anti-torque arm is hinged to a lower anti-torque arm, and the other end of the lower anti-torque arm is hinged to a frame. The folding and unfolding of the undercarriage and the folding of the frame are realized through series connection of the double four-bar mechanisms.
