The diameter of the large right pulley 402 is larger than the diameter of the small right pulley 404, for example, the ratio of the diameters of the large right pulley 402 and the small right pulley 404 is 3: 1.

The first embodiment is as follows: if the upper limb on one side of the patient moves autonomously to drive the upper limb on the other side to move forwards and backwards in a pushing and pulling way, the patient sits on the seat 3, the right hand holds the right handle 401, the left hand holds the left handle of the left movement mechanism 2, if the upper limb on one side of the patient can not move autonomously at all, a palm bandage is additionally arranged on the handle on the side which can not move autonomously, for example, the upper limb on the left side can not move autonomously, the palm bandage is fixed on the left handle to bandage the left palm of the patient, when in the initial position, the front side and the rear side of the left swing plate 6 are respectively aligned with the front side and the rear side of the right swing plate 5, the metal ball 8 is placed on the right track 501, the right upper limb pulls the right handle 401 backwards, or pushes the left handle forwards, the lower end of the right swing rod 408 swings forwards, the lower end of the left swing rod of the left movement mechanism 2 swings backwards, the right swing plate 5 inclines, the front is high and the rear is low, the metal ball rolls backwards along the right track 501 and accelerates, rolling to the left end of the right rear linear rail 5013, the right end of the left front linear rail 6011, if not swung backward to a position aligned with the left end of the right rear linear rail 5013, the patient continues to push the left handle forward, or pulls the right handle backward, when the right end of the left front linear rail 6011 is aligned with the left end of the right rear linear rail 5013, the left end of the right rear linear rail 5013 is higher than the right end of the left front linear rail 6011, the height of the right end of the left front linear rail 6011 to the middle of the left half ring rail 6012 becomes gradually lower, the metal ball 8 rolls at an accelerated speed, and at this time the left upper limb of the patient is pulled backward, the right upper limb is pulled forward, both upper limbs are moved in opposite directions, the left swing plate 6 is inclined and the height of the front side becomes higher, the metal ball 8 rolls backward along the left rail 601, the metal ball 8 rolls to the right end of the left rear linear rail 6013, if the left end of the right front linear rail 5011 of the right swing plate 5 is not aligned with the right end of the right rear linear rail 6013, the left side of the upper limb of the patient continues to be pulled backwards, the right upper limb continues to be pulled forwards, when the left end of the right front linear rail 5011 of the right swinging plate 5 is aligned with the right end of the left rear linear rail 6013, the right end of the left rear linear rail 6013 is higher than the left end of the right front linear rail 5011, the metal ball 8 rolls onto the right rear linear rail 5013, the rolling cycle of the metal ball 8 on the right swinging plate 5 and the left swinging plate 6 is completed once, then the right upper limb pulls the right handle 401 backwards, or pushes the left handle forwards, and the rolling cycle of the metal ball on the right swinging plate 5 and the left swinging plate 6 continues.

The patient controls the pulling speed of the two upper limbs back and forth, when the metal ball 8 rolls to the left end of the right rear linear rail 5013, the right end of the left front linear rail 6011 is just aligned with the left end of the right rear linear rail 5013, and when the metal ball 8 rolls to the right end of the left rear linear rail 6013, the left end of the right front linear rail 5011 is just aligned with the right end of the left rear linear rail 6013, the rolling circulation speed of the metal ball 8 on the right swinging plate 5 and the left swinging plate 6 is accelerated, and the patient is stimulated to perform rehabilitation training according to fixed motion intensity.

Example two: if the patient's upper limb movement function reaches a certain force, at the start position, the front and rear sides of the left swing plate 6 are aligned with the front and rear sides of the right swing plate 5, respectively, the metal ball 8 is placed on the right rail 501, the right upper limb pushes the right handle 401 forward, or pulls the left handle backward, the lower end of the right swing link 408 swings backward, the lower end of the left swing link of the left movement mechanism 2 swings forward, the metal ball 8 realizes a movement trajectory in the opposite direction to the first embodiment by means of the potential energy generated by the inclination of the right swing plate 5, and it is required that when the metal ball 8 rolls to the left end of the right front linear rail 5011, the right end of the left rear linear rail 6013 is aligned with the left end of the right front linear rail 5011 just right, and when the metal ball 8 rolls to the left end of the left front linear rail 5011, the left end of the right rear linear rail 5013 is aligned with the right end of the left front linear rail 6011 just right end, thereby increasing the difficulty of the patient.
