During the use, when the user carries out active training, can drive the rotation of axle one 4 at last, through the transmission of axle one 4, can drive the synchronous rotation of cylindrical cam 20, because the movable plate 11 can only control spacing slip on bedplate 1 for the movement track of linking arm one 18 and linking arm two 19 all receives the restriction, can only control horizontal migration.

When the first shaft 4 of the cylindrical cam 20 rotates, the first spherical slider 21 on the connecting arm two 19 slides relative to the inner wall of the outer contour sliding slot on the cylindrical cam 20, and under the guidance of the sliding slot, the first spherical slider 21 can drive the connecting arm two 19, the connecting arm one 18 and the moving plate 11 to horizontally reciprocate on the seat plate 1.

The meshing teeth 12 can synchronously move left and right through the transmission of the moving plate 11; under the matching of the supporting plate 17, the arc-shaped positioning plate 16 and the arc-shaped through groove 15 formed in the surface of the semi-circular gear 13, the semi-circular gear 13 can stably rotate in a fixed axis manner, and after the meshing teeth 12 meshed with the semi-circular gear 13 move left and right along with the moving plate 11, the semi-circular gear 13 is driven to rotate in the fixed axis manner;

through the left and right movement of the moving plate 11 and the transmission of the transmission rod 25, the piston rod 24 can drive the piston plate 23 to move left and right in the air storage shell 22, so that the sealed space in the air storage shell 22 is continuously increased and decreased, when the space is reduced, the air in the air storage shell 22 is transferred to the semicircular air bag 14 through the air duct 26, the air in the semicircular air bag 14 expands after the air in the semicircular air bag 14 increases, a user puts the thigh skin behind the fossa knee on the semicircular air bag 14 in advance, and finally wraps and fixes the legs of the user through the expansion change of the semicircular air bag 14, the legs of the user can also synchronously twist by a small angle along with the rotation of the semicircular ring gear 13, the movement angles of the hip joint and the knee joint of the user can be trained through the twisting, and in the practical use process, the inward rotation or outward rotation of the legs, the path trend of the outer contour sliding groove on the cylindrical cam 20 can be determined, and in the actual use process, the cylindrical cam 20 with different horizontal placement angles can be arranged to meet different requirements of outward rotation and inward rotation of the leg of a user.

The number of backup pad 17 on the arc locating plate 16 is two, and leans on the bottom of rear side backup pad 17 and the last fixed surface of bedplate 1 to be connected, leans on the rear side of front side backup pad 17 and the front side fixed connection of bedplate 1.

Through the setting of two backup pads 17 on the arc locating plate 16, can strengthen the fixed intensity in location of arc locating plate 16, avoid single backup pad 17 to appear rocking after fixing arc locating plate 16 for the dead axle rotational stability degree of semicircle ring gear 13 reduces, and two backup pads 17 all are the adaptability installation on bedplate 1 around on the arc locating plate 16.

The inner wall of the air storage shell 22 is fixedly connected with a damping spring 38, and one end of the damping spring 38, which is far away from the inner wall of the air storage shell 22, is fixedly connected with the side surface of the piston plate 23.

Through the arrangement of the damping spring 38 in the inner wall of the air storage shell 22, the fine vibration generated when the piston plate 23 slides in the air storage shell can be filtered and absorbed, and the influence of the vibration on the airtight effect of the piston plate 23 is avoided.

The sliding movement of the piston rod 24 in the air container 22 from side to side does not affect the airtight effect in the air container 22.

The rotation device 9 is provided with an auxiliary device 10, and the auxiliary device 10 can limit the thighs of the user during training, so that the phenomenon that the root part and the upper body of the thighs of the user lean forward by virtue of force is avoided, and the training effect is not as expected.

The auxiliary device 10 comprises a lifting toothed plate 27, the surface of the lifting toothed plate 27 penetrates through the upper surface of the seat plate 1 and is in limit sliding connection with the seat plate 1, teeth on the side surface of the lifting toothed plate 27 are meshed with teeth on the outer contour of the semi-circular gear 13, the rear side of the lifting toothed plate 27 is rotationally connected with a rotating connecting plate 28 through a pin shaft, the surface, close to the top, of the rotating connecting plate 28 is rotationally connected with a mounting seat 29 through a pin shaft, the upper surface of the mounting seat 29 is fixedly connected with a vertical plate 30, the rear side of the vertical plate 30 is fixedly connected with a horizontal push plate 31, the lower surface of the horizontal push plate 31 is fixedly connected with a bevel block 32, a bevel on the bevel block 32 faces backwards, the upper surface of the gas storage shell 22 is fixedly connected with a supporting template 33, the upper surface of the supporting template 33 is provided with a through hole, the through hole is connected with a lifting column 34 in an up-and-down limiting sliding mode through the through hole, the bottom of the lifting column 34 is fixedly connected with an n-shaped pressing plate 35, and the bottom of the mounting seat 29 is connected with the upper surface of the supporting template 33 in a limiting sliding mode.

When the lifting device is used, the rear half ring gear 13 is driven to rotate in a reciprocating mode, the lifting toothed plate 27 can lift on the seat plate 1 in a reciprocating mode through rotation, the mounting seat 29 can only slide on the supporting template 33 in a front-back limiting mode, namely the movement track is limited, and potential energy moves in the front-back horizontal direction.
