when the two legs of the athlete are separated or folded, the vertical shaft 10 is driven to rotate through the connecting plate 9, the vertical shaft 10 drives the gear 25 arranged on the outer wall of the vertical shaft to rotate, the gear 25 can circularly push the rack 26 inwards and compress the second spring 28 when rotating, and after the two legs stop swinging, the rack 26 is meshed with the gear 25 under the elastic force action of the second spring 28, so that resistance can be intermittently provided for the vertical shaft 10 through the second spring 28, and the two legs of the athlete need to overcome the resistance of the second spring 28 to separate or fold so as to achieve the effect of strength training.

Example two:

referring to fig. 7 and 8, on the basis of the first embodiment, an extension plate 17 is fixedly mounted on each of opposite sides of the two rotating wheels 11, a vertical rod 18 is fixedly mounted on the top of the end of the extension plate 17, a handle 19 is fixedly mounted on the top of the vertical rod 18, a player sits on the seat board 4, and then two legs are respectively placed on the first swing arm 5 and the second swing arm 6, and at this time, the player can directly grab the handle 19 with both hands and push the rotating wheels 11 to rotate through the extension plate 17, so that not only can arm strength be exercised, but also the first swing arm 5 and the second swing arm 6 can be freely pushed to open a certain angle, and flexibility training can be conveniently performed on the two legs;

if the flexibility training is carried out by using the legs without using the handle 19, the ligament is difficult to stretch under the limitation of self-strength, and if the arms are used as a power source, the stretching angles of the two legs can be freely controlled, so that the ligament can be effectively stretched;

as shown in fig. 5, outer grooves for moving the extension plates 17 are formed on opposite sides of the two outer rings 12, so as to facilitate the movement of the extension plates 17;

as shown in fig. 8, a plurality of hanging rings 20 are uniformly arranged on two sides of the outer wall of the extension plate 17, a side plate 21 is further fixedly mounted between the bottom plate 1 and the top plate 3, a training spring 22 is fixedly mounted on the side plate 21, a tail plate 23 is fixedly mounted at the tail end of the training spring 22, a hook 24 is arranged on the outer wall of the tail plate 23, and the hook 24 is hung on the hanging rings 20;

the training spring 22 is hung on the hanging ring 20 at different positions through the hook 24, so that the extension plate 17 has different resistance forces when rotating (the closer the hanging position is to the vertical rod 18, the larger the pulling force is), and the resistance force of the extension plate 17 when rotating can be conveniently adjusted;

when the handle 19 is not used for purely performing leg strength training, the resistance of the first swinging arm 5 and the second swinging arm 6 during rotation can be freely adjusted through the extension plate 17 with adjustable resistance, so that the training effect is better;

when the handle 19 is used for the arm strength training and the leg flexibility training, the extending plate 17 with adjustable resistance can select the resistance with proper magnitude according to the self condition to train the arm muscle.

The working principle and the using process of the invention are as follows:

a sportsman sits on the seat board 4, then two legs are respectively placed on the first swing arm 5 and the second swing arm 6, and at the moment, the two hands of the sportsman can also directly hold the handles 19 to push the rotating wheels 11 to rotate through the extension boards 17, so that the arm strength is exercised, and the first swing arm 5 and the second swing arm 6 can be freely pushed to open a certain angle, so that the flexibility training of the two legs is facilitated;

the training spring 22 is hung on the hanging ring 20 at different positions through the hook 24, so that the extension plate 17 has different resistance in rotation, the resistance in rotation of the extension plate 17 can be conveniently adjusted, the resistance in rotation of the first swing arm 5 and the second swing arm 6 can be freely adjusted through the extension plate 17 with adjustable resistance when the handle 19 is not used for purely performing leg strength training, and the training effect is better; when the handle 19 is used for the arm strength training and the leg flexibility training, the extending plate 17 with adjustable resistance can select the resistance with proper magnitude according to the self condition to train the arm muscle.
