VEHICLE TRACTOR

The present invention relates to the field of tractors, and discloses a vehicle tractor. The vehicle tractor includes a traction front arm which is inserted and mounted in a trailer inserting end, and a traction rear arm which is mounted at a vehicle head connecting end. Through an arranged insertion prompting mechanism, under the action of damping telescopic rods and a connecting spring, a turning-over plate is abutted against the vehicle head connecting end, whereby a limiting effect is achieved, and the vehicle head connecting end is prevented from sliding; and on the other hand, when the turning-over plate turns over, the meshing gear on a front side of the turning-over plate moves upwards to be meshed with the transmission gear, at this time, the transmission gear rotates clockwise, connecting arms connected to the transmission gear through transmission shafts rotate clockwise along with the transmission gear.
