Abstract
A sliding method on ice-surface aims at solve the problems of power output and poor durability and the difficulty in large-scale promotion. An ice-surface sliding tool includes a seat board, a U-shaped rod, sliding plates, H-shaped connecting frames, a pushing device, a hand-operated chain wheel and a reversing gear. One end of the upper end surface of the seat board is provided with a backrest. The U-shaped rod is provided on the side wall of the other end of the seat board. The lower end of the seat board is symmetrically provided with two sliding plates in parallel to each other. The sliding plates are connected with the lower end surface of the seat board through the H-shaped connecting frames. The pushing device is rotationally provided between the two H-shaped connecting frames. The hand-operated chain wheel is on the upper end of the U-shaped rod through a support bar.
