Firstly, the first bolt 148 is twisted to rotate reversely, the first bolt 148 rotates reversely to be separated from the first threaded hole 144, then the first bolt 148 is pulled to move outwards to be separated from the elongated hole 147, the connecting rope 145 hangs the first bolt 148, then the handle 146 is shaken to rotate forwards and backwards alternately, the handle 146 rotates forwards and backwards alternately to drive the rotating shaft 149 to rotate forwards and backwards alternately, the rotating shaft 149 rotates forwards and backwards alternately to drive the reel 141 to rotate forwards and backwards alternately, the reel 141 rotates forwards and backwards alternately to drive the lifting block 5 to move upwards and downwards through the steel wire rope 142, and then drive seat 11 and reciprocate, when seat 11 reciprocated to suitable position, stop rocking handle 146, pass elongated hole 147 with first screw hole 144 contact with first bolt 148, twist first bolt 148 corotation and remove and fix handle 146 in first screw hole 144, stop twisting first bolt 148, people can sit on seat 11, place the foot on disc 17 and take exercises.

When people sit on the seat board 11 and place feet in the placing groove 19, the feet are moved to the space between the rubber blocks 20 at the front and the rear sides, the rotating board 25 is pulled to swing upwards, so that the clamping groove 28 is separated from the clamping block 27, the return spring 24 is stretched, the front and rear side sliding blocks 22 are pushed to move inwards on the sliding rail 21, the sliding blocks 22 move inwards to drive the first supporting rod 23 to move inwards, the first supporting rod 23 moves inwards to drive the rotating plate 25 to move inwards, meanwhile, the first support rod 23 moves inwards to drive the rubber block 20 to move inwards through the second bolt 30, the rubber block 20 moves inwards to be contacted with the foot to fix the rubber block, the sliding block 22 is stopped being pushed, the rotating plate 25 is loosened, the rotating plate 25 swings downwards under the action of the return spring 24, the clamping block 27 is clamped into the clamping groove 28, the clamping block 27 is matched with the clamping groove 28 to fix the rotating plate 25, further, the rubber block 20 is fixed, and the user can start exercising by turning the disc 17 with his foot. After the exercise, pull revolving plate 25 upward swing once more and make draw-in groove 28 break away from with fixture block 27, pull slider 22 again and outwards remove and reset, slider 22 outwards removes and drives first branch 23 outwards removal, and then drive block rubber 20 outwards and remove and reset, outwards remove and reset when revolving plate 25, loosen revolving plate 25, because of the effect of return spring 24, revolving plate 25 swings downwards and makes fixture block 27 card go into draw-in groove 28, when block rubber 20 damages, people can twist second bolt 30 and second screw hole 29 and break away from, then trade the block rubber 20 that damages for new block rubber 20, twist second bolt 30 and pass through second screw hole 29 with new block rubber 20 fixed, so, can make people better rotating disc 17, the exercise effect is better.

When people's feet are put on the disc 17 for exercise, the disc 17 rotates to drive the rotating rod 16 to rotate, the rotating rod 16 rotates to drive the annular grindstone block 31 to rotate, and the annular grindstone block 31 rotates to rub against the friction rod 34 to increase resistance, so that the feet of people need to rotate the disc 17 harder. When the resistance does not need to be increased, the pulling rotating handle 35 swings upwards to drive the screw 33 to rotate reversely, the screw 33 rotates reversely to drive the friction rod 34 to rotate reversely, and when the friction rod 34 rotates reversely and does not contact with the annular grindstone block 31, the pulling rotating handle 35 is stopped. Thus, people can rotate the disc 17 harder, and the exercise effect is improved.

When a person sits on the seat plate 11 and leans against the backrest plate 13, the backrest is in contact with the massage wheels 38, and the massage wheels 38 can massage the backrest when the body of the person moves. Thus, the user can feel more comfortable during exercise.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
