[0035] The implementation principle of this embodiment is:

[0036] The handle steering quick-change mechanism of the upper and lower limb active and passive rehabilitation training device is provided with a lower limb trainer 1. When using the device, the user sits on the top of the lower limb trainer 1, holds the handles 29 on the left and right sides with both hands, and then turns on the motor 5, and the output shaft of the motor 5 starts to rotate. The rotation of the output shaft of the motor 5 can drive the connecting shaft 24 to rotate, and the rotation of the connecting shaft 24 can drive the connecting key 26 to rotate, and the rotation of the connecting key 26 can drive the key slot 23 to rotate.

[0037] After using it for a period of time, the user pulls the return spring positioning member 15 axially upward, and the button 17 moves upward. The upward movement of the button 17 can move the telescopic shaft 18 upward, and then the telescopic shaft 18 can be separated from the positioning hole 22. At this time, the user turns the handle 29 upward, and the upward rotation of the handle 29 can drive the right crank 11 to rotate upward, and the upward rotation of the right crank 11 can drive the positioning seat 14 to rotate upward, and the upward rotation of the positioning seat 14 can drive the slider 21 to slide inside the slide groove 20, so that the positioning seat 14 can rotate upward. The positioning seat 14 continues to rotate, and the positioning seat 14 will contact the limit screw 16. At this time, the telescopic shaft 18 will move downward and enter the interior of another positioning hole 22, so that the positioning seat 14 can be connected to the rotating shaft sleeve 13, and the right crank 11 can be rotated 180 degrees and connected to the rotating shaft sleeve 13, so that the motor 5 can drive the right crank 11 to rotate again, so that the user can perform vertical cross training, thereby greatly improving the efficiency of crank switching and the convenience of operation, and enabling the user to switch between vertical cross training and vertical horizontal training on the same device.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] The handle steering quick-change mechanism of the upper and lower limb active and passive rehabilitation training equipment is provided with an adjustment mechanism 12. By pulling the return spring positioning piece 15 upward in the axial direction, the telescopic shaft 18 can be moved upward, and then the telescopic shaft 18 can be disengaged from the positioning hole 22, so that the right crank 11 can be rotated. Subsequently, the right crank 11 is rotated, and the rotation angle of the right crank 11 can be limited by the limit screw 16. The telescopic shaft 18 enters the inside of another positioning hole 22, and the right crank 11 can be quickly reversed, thereby greatly improving the efficiency of the crank reversing and the convenience of operation, and realizing the switching between the two training modes of vertical cross training and vertical horizontal training.
