The working principle is as follows: the motion process, motion pattern and composition of the left and right exercise arms 50 are substantially similar, differing only in the arrangement of the left and right traction wheel sets 71, 72, resulting in differences in the traction roping arrangement of the exercise cords 90 of the relevant portion.

When the swing arm main body 42 swings upwards, the anti-falling pull rope 61 is loosened, the pulling force on the sliding seat 65 is reduced, and the sliding seat 65 falls down, so that the air spring 62 is driven to extend downwards, the elastic force of the air spring 62 is used as power to generate downward assistance to the sliding seat 65 to assist the arm lifting action. When the swing arm main part 42 swings downwards, the anti-falling stay cord 61 is tensioned and pulled rightwards, the sliding seat 65 rises, so that the air spring 62 is driven to contract, the elastic force of the air spring 62 appears as resistance, the anti-falling stay cord 61 and the swing arm main part 42 generate resistance, the lower swing action is more difficult, the required external force is increased, but when the external force is removed, the swing arm main part 42 cannot fall down at once under the action of the air spring 62, and the safety precaution effect is achieved.

When the exercise rope 90 is stretched out in the exercise arm 50, taking the exercise arm 50 on the right side as an example, the whole exercise rope 90 is pulled rightward, and the traction plate 734 is driven to ascend through the guidance of the right traction wheel set 72, the guide fixed pulley 731, the guide fixed pulley set 732 and the guide movable pulley set 733, so that the acting force is generated on the motor 80 by the motor traction wheel 742 and the motor traction rope 75, and the motor 80 generates the reverse force, thereby playing the exercise effect. The exercise intensity is adjusted by adjusting the output of the motor 80. The pulling out of the left exercise arm 50 drives the other end of the exercise cord 90 to move to the left, which also drives the traction plate 734 to move up, generating a force on the motor 80. When the single arm exercises, the single-side force is exerted; when exercising both arms, a resultant force is exerted on the motor 80. Depending on the nature and number of the movable pulleys, the motor pulls the pull cord 75 to the right by a distance X when the exercise cord 90 on one side is extended by a distance of 6X. The bilateral exercise pull cords 90 are each pulled out a distance of 6X and the motor pulls the pull cord 75 to the right a distance of 2X. During double-arm training, the pulling force of the two sides on the exercise pull rope 90 is released, the motor pulls the pull rope 75 to move leftwards for a distance of 2X, and the two sides of the exercise pull rope 90 return inwards for a distance of 6X in each direction. During the single armed training, loosen the unilateral to temper pull rope 90's pulling force, motor traction stay rope 75 has moved the X distance left, tempers pull rope 90 and inwards resumes 6X distance. When the exercise arm 50 is rotated back and forth, the pull pin shaft 364 is pulled, and the bottom thereof is separated from the pin hole of the rotating plate and can rotate freely, and after the adjustment is completed, the pull pin shaft 364 is loosened, and the bottom thereof is automatically inserted into a new corresponding pin hole to be fixed under the action of the rotating elastic member 365. When the exercise arm 50 is swung up and down, the pull pin member 433 is pulled to separate the pull pin member 433 from the pin holes of the swing arm plate 41 and the swing arm plate 31, so that the exercise arm 50 can be directly swung, the pull pin member 433 is released, and a new pin hole is embedded under the action of the swing elastic member 435 to realize fixation. The stretching distance of the exercise pull rope 90 is effectively extended by the pulling mechanism 73, so that the exercise is more diversified.
