During active training, a patient holds the handle 601 by hand, and the handle 601 drives the rotating block 608 to rotate along the rotating plate 901 through the telescopic rod 602, the telescopic cylinder 603 and the sliding rod 604 to perform chest expanding movement; a pair of rotating blocks 608 are synchronously rotated by matching a synchronizing shaft 803 and a pair of synchronizing bevel gear sets 610; meanwhile, under the action of the sector-shaped gear ring 606, the planet gear 615 rotates in a reciprocating manner, and the planet gear 615 drives the crank block 613 to rotate in a reciprocating manner; the crank block 613 drives the sliding rod 604 to slide back and forth along the rotating block 608 through the cooperation of the crank screw 614, the sliding block 619, the second connecting rod 607 and the connecting block; in addition, the rotating block 608 drives the connecting bevel gear set 810 to move through the synchronous bevel gear set 610, the connecting bevel gear set 810 drives the driving wheel 804 to rotate, and the driving wheel 804 drives the sector teeth 805 to slide along the sector block 807; when the sector-shaped teeth 805 are in contact with the limiting block 806, the sector-shaped teeth 805 drive the sector-shaped block 807 to rotate through the limiting block 806, and the sector-shaped block 807 drives the first crank 802 to rotate through the first connecting rod 809; the adjustment of the amplitude of rotation of the exercise structure is achieved due to the limited amplitude of rotation of the segments 807 as a result of the adjustment of the actual crank length of the segments 807.
During passive training, the motor 801 rotates, the motor 801 drives the fan-shaped block 807 to rotate through the first crank 802 and the first connecting rod 809, and the fan-shaped block 807 rotates until the limiting block 806 contacts with the fan-shaped teeth 805 to drive the fan-shaped teeth 805 to synchronously rotate; the sector teeth 805 drive the driving wheel 804 to rotate, the driving wheel 804 drives the synchronizing shaft 803 to rotate through the bevel gear group 810, the synchronizing shaft 803 drives the rotating block 608 to rotate along the rotating plate 901 through the bevel gear group 610, and the rotating block 608 drives the patient to perform chest expanding movement through the sliding rod 604, the telescopic cylinder 603, the telescopic rod 602 and the handle 601; (ii) a Meanwhile, under the action of the fan-shaped gear ring 606, the planet gear 615 rotates in a reciprocating mode, and the planet gear 615 drives the crank block 613 to rotate in a reciprocating mode; the crank block 613 drives the sliding rod 604 to slide back and forth along the rotating block 608 through the cooperation of the crank screw 614, the sliding block 619, the second connecting rod 607 and the connecting block.
