[0036] Working principle: When the utility model is in use, the exerciser holds the pull rod 25, the first motor 6 works, the first motor 6 drives the first incomplete gear 8 to rotate, when the first incomplete gear 8 is meshed with the first transmission gear 9, the first transmission gear 9 is driven to rotate, the first transmission gear 9 drives the rotating shaft 4 to make the arc plate 5 swing a certain angle, the arc plate 5 drives the exerciser's arm to swing to one side, when the first motor 6 works, it drives the transmission wheel 13 thereon to rotate, under the action of the belt 14, drives the transmission wheel 13 on the transmission shaft 11 to rotate, so that the transmission shaft 11 rotates, the transmission shaft 11 drives the second transmission gear 12 above to rotate, the two second transmission gears 12 are meshed with each other, so that the two second transmission gears 12 rotate in opposite directions, driving the lower transmission shaft 11 to rotate, and the transmission wheel 13 on the lower transmission shaft 11 rotates accordingly The first incomplete gear 8 rotates in the opposite direction to the second incomplete gear 10. When the first incomplete gear 8 is disengaged from the surface of the first transmission gear 9, the second incomplete gear 10 meshes with the first transmission gear 9, so that the first transmission wheel 13 drives the rotating shaft 4 to make the arc plate 5 swing to the other side, thereby driving the two arms of the exerciser to pull back and forth, and performing rehabilitation exercises on the two arms of the exerciser, thereby performing auxiliary exercises on the exerciser. In the later stage of rehabilitation exercises, there is no need for auxiliary exercises. At this time, the first motor 6 does not work, and the patient can directly pull the pull rod 25 to exercise, thereby performing auxiliary exercises on the exerciser in the early stage of exercise. The friendliness is better, and the practicality of the device is improved.

[0037] When the exerciser performs the later stage of exercise, the exerciser pulls the pull rod 25 downward, drives the pull rope 24, causes the pull plate 23 to move downward, and the spring 22 is compressed. The exerciser performs the exercise. According to the actual needs of the exerciser, the elastic force of the spring 22 can be adjusted to increase the intensity of the exercise. At this time, the threaded rod 20 is rotated, and the threaded rod 20 drives the adjustment disk 21 to move, so that the spring 22 is compressed. As the position of the adjustment disk 21 is adjusted, the deformation of the spring 22 is adjusted, thereby adjusting the elastic force of the spring 22, and adjusting the intensity of the exercise. Therefore, the elastic force of the spring 22 can be adjusted according to the actual needs of the exerciser, which is convenient for the exerciser to use.
