Specifically, both ends of the pedal belt 4 are fixed on both sides of the pedal plate 3 by fixing members 5. When the fixing member 5 passes through the first through hole 41 with the lowest height on the pedal belt 4 and is connected with the pedal plate 3, the length of the pedal belt 4 between the fixing points on the two sides is the largest, and the pedal belt 4 is the looest. When the fixing member 5 passes through the first through hole 41 with the highest height on the pedal belt 4 and is connected with the pedal plate 3, the length of the pedal belt 4 between the fixing points on the two sides is the smallest, and the pedal belt 4 is the looest. The pedal belt 4 is provided with a plurality of first through holes 41 on the left and right sides, and the first through holes 41 with different heights on the two sides can be selected for fixing, so that small-amplitude adjustment and large-amplitude adjustment can be performed.
