[0032] Furthermore, the purpose of the locking nut 3 is to adjust the distance between the first tensile end 11 and the second tensile end 21, thereby achieving a better fit and connection. The first tensile end 11 is connected to the agricultural machinery equipment, while the second tensile end 21 is connected to the traction agricultural implement. When vibration occurs, the damping and buffering effect of the two springs can greatly alleviate the impact force and avoid causing rigid damage to the traction agricultural implement.
