The invention discloses a mechanical knot formation method of a heterogenous 8-shaped knot, which belongs to the technical field of strapping. The heterogenous 8-shaped knot is formed by changing one of two X-shaped cross structures at the middle part of the standardized 8-shaped knot into Chinese doughnut-shaped twisted structure. The heterogenous 8-shaped knot is formed by the following steps: hawk-mouth-shaped knotter jaw hooks the rope to finish two circles of twisting so that one end head of the rope crosses an alpha-shaped rope ring encircling the knotter jaw, thus forming the heterogenous 8-shaped knot. The heterogenous 8-shaped knot has more complex twisting relation and increased twisting area than half-knot, thus effectively reducing slipping of buckles at the tensioning state of the rope and improving reliability and stability of buckles.
