[0039] The transmission member 85 includes a power block 851 that is slidably inserted in the guide groove 33. The end of the power block 851 away from the fixed block 2 is fixedly connected to a transmission spring 852. The end of the transmission spring 852 away from the power block 851 is fixedly connected to the groove wall of the guide groove 33 away from the fixed block 2. The transmission spring 852 causes the power block 851 to be located at the end of the guide groove 33 close to the fixed block 2; an accommodating cavity 36 is provided in the mounting block 3, and the surfaces of the two power blocks 851 away from each other are fixedly connected to a support rod 853, and the length direction of the support rod 853 is arranged along the radial direction of the matching rod 4.

[0041] When the upper limb training part needs to be installed on the main body bracket 1, align the guide groove 33 with the guide rod 71, and then push the mounting block 3 in the direction close to the fixed block 2 so that the guide rod 71 is inserted into the guide groove 33. During this process, the mating rod 4 contacts the bottom wall of the mating groove 32. At this time, the plug-in rod 81 is aligned with the plug-in sleeve 83. As the mounting block 3 continues to move, the mounting block 3 pushes the mating rod 4 to move into the fixed block 2 and compresses the limit spring 41. The movement of the mating rod 4 causes the plug-in rod 81 to move toward the higher side of the driving block 821 and compress the connecting spring 823. At the same time, the driving block 821 pushes the plug-in rod 81 to move outward from the mating rod 4.

[0042] When the guide rod 71 moves into the guide groove 33, the guide rod 71 pushes the power block 851 to move and compresses the transmission spring 852. The power block 851 moves and drives the support rod 853 and the transmission block 854 to move, and also rotates the hinge rod 856, so that the hinge rod 856 pushes the corresponding transmission rod 855 to move in the direction close to the matching groove 32. The transmission rod 855 drives the corresponding plug-in sleeve 83 to move, so that the plug-in sleeve 83 moves into the matching groove 32, and also rotates the support rod 853 and the transmission block 854. The spring 84 is compressed; when the mounting block 3 moves to contact the stop plate 74, the plug-in sleeve 83 moves into the copper ring 6, and the plug-in rod 81 is plugged into the plug-in sleeve 83. The plug-in rod 81 cooperates with the plug-in sleeve 83, the contact switch 75 is closed, and the electromagnet sheet 76 is controlled to work and magnetize, thereby adsorbing the mounting block 3, so that the transmission block 854 maintains its position at this time, and the mounting block 3 is connected to the fixed block 2, restricting the two from relative movement in the axial direction of the connecting rod 51.

[0043] To change the direction of upper limb exercise, the wristband 52 is rotated, which in turn rotates the connecting rod 51, which in turn rotates the mating rod 4, the plug rod 81, the plug sleeve 83, the mounting block 3, the guide rod 71, and the stop plate 74, while also compressing the guide spring 73. When the axial direction of the handwheel 31 reaches the desired direction, the wristband 52 is stopped. This arrangement allows the user to independently and more conveniently install the upper limb training unit and change the circumferential direction of the handwheel 31, making it easier for the user to use the upper and lower limb rehabilitation training device.

[0044] When the upper limb training part needs to be removed, the control contact switch 75 is disconnected. At this time, the electromagnet sheet 76 loses its magnetism, the limit spring 41 recovers its deformation and pushes the matching rod 4 and the mounting block 3 to move away from the fixed block 2. At the same time, the connecting spring 823 recovers its deformation, causing the plug-in rod 81 to move into the matching rod 4, and the transmission spring 852 and the support spring 84 recover their deformation, causing the plug-in sleeve 83 to move into the mounting block 3; when the limit spring 41 returns to its initial state, the transmission spring 852 and the support spring 84 also return to their initial state. At this time, the plug-in rod 81 and the plug-in sleeve 83 return to their initial position. At this time, the mounting block 3 and the matching rod 4 are released, and the user can remove the mounting block 3 from the fixed block 2.

[0045] The implementation principle of an upper and lower limb rehabilitation training device in an embodiment of the present application is: align the guide groove 33 with the guide rod 71, push the mounting block 3 in the direction close to the fixed block 2, insert the copper ring 6 into the matching groove 32, until the mounting block 3 contacts the stop plate 74, at this time the plug-in sleeve 83 moves into the copper ring 6, the plug-in rod 81 is plugged into the plug-in sleeve 83, the contact switch 75 is closed, so that the mounting block 3 is adsorbed on the mounting block 3 through the electromagnet sheet 76, so that the plug-in rod 81 and the plug-in sleeve 83 remain matched, and the mounting block 3 and the fixed block 2 can be fixed; when the axial direction of the handwheel 31 needs to be changed, rotate the hand ring 52 until the axial direction of the handwheel 31 reaches the desired direction.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
