When sled stopped sliding, after the people left the seat, the seat one end of elasticity that leans on the spring upwarp, drive the rudder piece through the connecting rod and raise, make the rudder piece pack up, the sled empty wagon of being convenient for is transported, when using, the people sits and can push down the multi-disc through the seat on the seat, makes the rudder piece performance normal function.

The steering of the steering handle can also control the skis to climb over the snow bag, so that the same jumping action as the skis is realized, and the driving pleasure is improved.

The rudder plate is positioned behind the rudder stock and participates in steering, so that the turning radius of the sled is reduced, and the driving sensitivity of the sled is improved.

The rudder plate which is positioned right below the rudder stock is positioned at the center of the sled, so that the sled has the flexibility of a single-plate ski and the safety and the operability of the sled, and the driving flexibility and the driving pleasure of the sled are greatly improved.

The double-rudder plate structure of the two sides of the rudder stock can improve the stability of the sled, has large area, reduces the pressure of the sled to the snow, can improve the trafficability characteristic and the bearing capacity of the sled, further enhances the stability of the sled, enables the sled to be more easily operated, and passes through the connecting structure, the double-rudder plate structure can synchronously rotate, and has good flexibility and easy operation.
