The invention discloses a ski simulator with the safety protection function and a use method of the ski simulator. The ski simulator comprises a curved support plate, a simulating slide plate, an arm-rest frame, two bottom plates and an adjusting mechanism, the bottom plates are welded to two bottom ends of the curved support plate, the arm-rest frame is welded between top surfaces of the bottom plates, the simulating slide plate is slidably connected to the upper portion of the curved surface of the curved support plate, the adjusting mechanism is fixed on the inner curved surface of the curved support plate, and a strip-type through hole is formed in the top surface of the curved support plate along the curved side thereof. Through rotation of a two-way lead screw, moving blocks are driven to move towards each other to change the shape variable between spring ropes and achieve the adjustment of different training intensity, and simpleness in structure and convenience in operation areachieved; by the aid of the flexibility of balls in ball cups, each ball is connected with a pedal through a support rod, convenience is brought to training personnel to simulate ankle operation during training, and the sense of operation reality of the ski simulator is enhanced.
