4. The snowmobile of claim 1, wherein the snowmobile body is provided with a plurality of rotating mechanisms inside, the output end of each rotating mechanism is provided with a torsion bar extending out of the snowmobile body, and each swing arm is connected to the corresponding torsion bar.
5. A multi-function snowmobile according to any one of claims 1 to 4, wherein the outer wall of the screw propulsion buoy is provided with a propulsion helix for providing a propulsion power, the rotation of the screw propulsion buoy causing the propulsion helix to rotate.
6. The multi-function snowmobile of claim 5, wherein the propelling spirals of the spiral propelling floats on both sides of the snowmobile body are opposite and the direction of rotation of the spiral propelling floats on both sides of the snowmobile body are opposite.
7. The snowmobile of claim 6, wherein each of the spiral propelling floats is a closed hollow structure.
8. The multi-functional snowmobile of claim 1, characterized by, be equipped with on the snowmobile body a plurality of wheels that are used for supporting the snowmobile body to travel when the spiral propulsion flotation pontoon lifts up, wheel's rotation axle center department is equipped with and is used for driving its rotatory in-wheel motor.
9. A multi-function snowmobile of claim 8, wherein a suspension mechanism is provided between the wheels and the snowmobile body for shock absorption.
10. The running method of the multifunctional snowmobile is characterized by comprising the following steps:
preparation before hard road surface advancing: keeping the spiral propelling buoy to rotate, driving the torsion bar to rotate by the rotating mechanism in the advancing process of the snowmobile body, driving the swing arm to swing by the rotation of the torsion bar, lifting the spiral propelling buoy and separating from an advancing surface, enabling the wheels to gradually approach and finally support on the advancing surface, and stopping the rotation of the spiral propelling buoy;
advancing on a hard road surface: the hub motor drives the wheels to rotate and drives the snowmobile body to move forwards or backwards on a hard road surface;
preparation before traveling on snowfield: the spiral propelling buoys are opened to rotate, the rotating mechanism drives the torsion bars to rotate, the torsion bars rotate to drive the swing arms to swing, the roller support rods fall down and contact with the advancing surface, the torsion bars continue to rotate, the spiral propelling buoys on the two sides of the snowmobile body gradually approach to lift the snowmobile body and the wheels and separate from the advancing surface;
advancing on snow: the spiral propelling buoy rotates forwards or backwards to drive the snowmobile body to move forwards or backwards.
