The pedal blocks 2 comprise sliding seats and right-angle pedals, the two sliding seats are respectively fixed at the front end and the rear end of the right-angle pedals, and the pedal blocks 2 are connected onto the sliding rails 11 in a sliding mode through the sliding seats. The support 1 is obliquely arranged, the base is arranged at the lower end of the support 1, and the top seat is arranged at the upper end of the support 1. The base includes first splice block 31, right angle piece 32, bradyseism spring 34, grounding piece 33 and first gim peg 37, first splice block 31 is fixed in on grounding piece 33 through a plurality of bradyseism springs 34, grounding piece 33's bottom is provided with the first sawtooth 35 that is used for the reinforcing to grab the land fertility, first connecting groove 36 has been seted up on the slope of first splice block 31, first connecting groove 36 is inserted to the lower extreme of support 1, first fixed orifices 12 has been seted up to the lower extreme of support 1, second fixed orifices 13 has been seted up to the upper end of support 1, first gim peg 37 is inserted from the top of first splice block 31, and first gim peg 37 passes first fixed orifices 12, right angle piece 32 is fixed in the right side of first splice block 31, right angle piece 32's left end is connected with the right angle footboard that is located the least significant end. The top seat comprises a panel 42, a second connecting block 41 and a second fixing bolt 45, the panel 42 is fixed at the top of the second connecting block 41, a second connecting groove 46 is formed in the bottom of the second connecting block 41, the upper end of the support 1 is inserted into the second connecting groove 46, the second fixing bolt 45 is inserted from the top of the second connecting block 41, the second fixing bolt 45 penetrates through the second fixing hole 13, and the topmost right-angle pedal on the support 1 abuts against the second connecting block 41.

The length of support 1 chooses suitable length according to the height of floor, then inserts the lower extreme of support 1 on the first connecting slot 36 of base, then inserts first gim peg 37 toward first connecting slot 36 in, and first gim peg 37 inserts first connecting slot 36 and the first fixed orifices 12 of support 1 in, pins support 1 and base. The pedal 2 is then slid onto the slide rail 11 of the bracket 1. According to the height of the floor, the slide rail 11 is filled with the tread blocks 2, the filled tread blocks 2 are stacked on each other, and the tread block 2 located above is pressed against the tread block 2 located below. After the pedal block 2 fills the bracket 1, the top seat is installed. The upper end of the support 1 is inserted into the second connecting groove 46 of the second connecting block 41 of the top seat, and then the second fixing bolt 45 is obliquely inserted into the second connecting groove 46, and the second fixing bolt 45 passes through the second fixing hole 13 at the top end of the support 1, so that the support 1 is fixed on the second connecting block 41.
