When the operator F steps on the right foot downwards, the second section 732 drives the second slide carriage 6 to move downwards on the second slide rail 5, and drives the second pedal 20 and the first handle 8 to move downwards synchronously, i.e. the operator F moves the right foot downwards and the operator F moves the left hand downwards synchronously. At this time, the second section 732 drives the first section 731 to move upward, and since the first sliding seat 4 is combined with the first section 731 of the transmission member 73, the first pedal 9 and the second handle 10 are jointly fixed to the first sliding seat 4. Therefore, when the first slide carriage 4 moves upward and drives the first pedal 9 and the second handle 10 to move upward synchronously, the left foot and the right hand of the operator F move upward synchronously. Thus, when the right foot of the operator F steps down, the left hand of the operator F synchronously moves down, and the left foot and the right hand of the operator F move up. The left foot and the right foot are stepped downwards in turn, so that the left foot and the right hand, and the right foot and the left hand can respectively move up and down for training, the synchronous up-and-down movement of the right foot and the left hand, and the synchronous up-and-down movement of the left foot and the right hand conform to the natural rhythm of four limbs.

The left foot of the operator F applies force to the first sliding seat 4, and the right foot of the operator F applies force to the second sliding seat 6, so that the force application on the first side 21 and the second side 22 can be balanced, and the effect of stable operation can be achieved. The first slide 4 is fixed to the first section 731 of the transmission member 73, the second slide 6 is fixed to the second section 732, the first pedal 9 is fixed to the first slide 4, and the first handle 8 is fixed to the second slide 6, so that the left foot and the left hand of the operator F always move away from and close to each other when operating. The second pedal 20 is fixed to the second slide 6, and the second handle 10 is fixed to the first slide 4, so that the right foot and the right hand of the operator F always move away from and close to each other when operating. Therefore, the left foot and the right hand of the operator F can synchronously slide upwards and downwards, and the right foot and the left hand can synchronously slide upwards and downwards, so that the limb climbing device is in accordance with limb actions during climbing.
