The motion of stay cord 28 drives the motion of spacing connecting rod 35, make spacing connecting rod 35 begin to rotate round second pivot 34 under the effect that receives the pulling force of stay cord 28, thereby drive the motion of second spring 36 and make second spring 36 compressed, make spacing connecting rod 35 and spacing groove 37 separate, because initial condition spacing connecting rod 35 is located spacing groove 37, make support slider 17 can receive spacing connecting rod 35's effort when having the rotation trend, thereby make support slider 17 unable rotation, consequently after spacing connecting rod 35 separates with spacing groove 37, spacing effect of spacing connecting rod 35 has been relieved.

When the user uses the foot, the foot is separated from the supporting bracket 13, at this time, because the supporting bracket 13 does not bear the force from the user any more, the first spring 26 does not bear the force from the slider 23 any more, so that the first spring 26 starts to reset, and the third link 27 is driven to start to move upwards, so that the connection end of the pull rope 28 and the third link 27 moves upwards, and therefore the second spring 36 does not bear the force from the limit link 35 any more, so that the second spring 36 starts to reset, and the limit link 35 is driven to move towards the direction of the limit groove 37; because the limiting connecting rod 35 can not necessarily just move into the limiting groove 37 in the moving process, when the limiting connecting rod 35 moves to the position between the limiting grooves 37, the limiting connecting rod 35 can contact with the second rubber block 39, because the central lines of the limiting connecting rod 35 and the second rubber block 39 are parallel and the central lines do not pass through the circle center of the supporting sliding block 17 but form an acute angle, and the first rubber block 38 and the second rubber block 39 on the limiting connecting rod 35 both have certain elasticity, the supporting sliding block 17 can be continuously pushed to rotate in a small amplitude when the first rubber block 38 is in contact with the second rubber block 39, so that the limiting connecting rod 35 can move into the nearest limiting groove 37, and the limiting effect when no person uses the limiting connecting rod is achieved.

The working principle is as follows: when the user uses the device, the user places the feet on the support bracket 13, and the hands grasp the handrail 16, and then starts to twist; when the supporting bracket 13 receives the force transmitted from the foot, the supporting bracket 13 guides the force to the supporting slider 17, and then the supporting slider 17 moves downward, so that the supporting bracket 13 also moves downward, and the first ball 18 is driven to move downward, so that the first ball 18 is engaged with the groove on the supporting base 12, the rolling resistance is reduced, and the first ball 18 is kept to rotate stably, thereby keeping the supporting bracket 13 to rotate stably.

The downward movement of the supporting sliding block 17 drives the second ball 20 to move downward, so that the second ball 20 is engaged with the groove on the second connecting rod 11, the rolling resistance is reduced, the downward movement of the supporting sliding block 17 drives the sliding block 23 to move downward, thereby compressing the first spring 26, and simultaneously driving the downward movement of the third connecting rod 27, thereby driving the movement of the pulling rope 28, the movement of the pulling rope 28 drives the movement of the limiting connecting rod 35, so that the limiting connecting rod 35 starts to rotate around the second rotating shaft 34 under the action of the pulling force of the pulling rope 28, thereby driving the movement of the second spring 36 to compress the second spring 36, so that the limiting connecting rod 35 is separated from the limiting groove 37, because the initial state limiting connecting rod 35 is located in the limiting groove 37, the supporting sliding block 17 can receive the acting force of the limiting connecting rod 35 when having a rotation tendency, thereby making the supporting sliding block 17 unable to rotate, therefore, after the stopper link 35 is separated from the stopper groove 37, the stopper effect of the stopper link 35 is released.

When the user uses the foot, the foot is separated from the support bracket 13, at this time, because the support bracket 13 does not bear the force from the user any more, the first spring 26 does not bear the force from the slider 23 any more, so that the first spring 26 starts to reset, the third link 27 is driven to start to move upwards, the connecting end of the pull rope 28 and the third link 27 is driven to move upwards, the second spring 36 does not bear the force from the limit link 35 any more, the second spring 36 starts to reset, and the limit link 35 is driven to move towards the direction of the limit groove 37; because the limiting connecting rod 35 can not necessarily just move into the limiting groove 37 in the moving process, when the limiting connecting rod 35 moves to the position between the limiting grooves 37, the limiting connecting rod 35 can contact with the second rubber block 39, because the central lines of the limiting connecting rod 35 and the second rubber block 39 are parallel and the central lines do not pass through the circle center of the supporting sliding block 17 but form an acute angle, and the first rubber block 38 and the second rubber block 39 on the limiting connecting rod 35 both have certain elasticity, the supporting sliding block 17 can be continuously pushed to rotate in a small amplitude when the first rubber block 38 is in contact with the second rubber block 39, so that the limiting connecting rod 35 can move into the nearest limiting groove 37, and the limiting effect when no person uses the limiting connecting rod is achieved.
