[0033] Embodiment 2, this embodiment is based on the previous embodiment, as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 And attached Figure 7 As shown, the reciprocating dynamic traction component 5 also includes an airflow duct 10 fixedly arranged on the circumferential side wall of the diverter cylinder 21, and a mounting plate 8 symmetrically fixedly arranged on the upper wall of the base 1, one end of the airflow duct 10 is through-connected with the alternating diverter holes 24, and a telescopic air cylinder 9 is horizontally fixedly arranged on one side wall of the mounting plate 8, and the base end of the telescopic air cylinder 9 is through-connected with one end of the airflow duct 10 away from the diverter cylinder 21.

[0034] Embodiment 3, this embodiment is based on the previous embodiment, as shown in the attached Figure 1 -Attached Figure 7 As shown, the reciprocating dynamic traction assembly 5 also includes a guide groove 6 symmetrically opened on the upper wall of the base 1, a moving plate 7 horizontally slidably arranged in the guide groove 6, an adapter plate 20 fixedly arranged on a side wall of one side of the moving plate 7, a push rod 14 with one end horizontally fixed on the adapter plate 20, and a rubber piston 15 fixedly arranged at one end of the push rod 14 away from the adapter plate 20. A fixed plate 19 is symmetrically fixed on the base 1, a fixed air cylinder 13 is horizontally fixed on a side wall of one side of the fixed plate 19, the rubber piston 15 is slidably arranged in the fixed air cylinder 13, and the output end of the telescopic air cylinder 9 is fixedly connected to the moving plate 7.

[0035] Embodiment 4, this embodiment is based on the previous embodiment, as shown in the attached Figure 1 -Attached Figure 7 As shown, a multi-stage cylinder 11 is fixedly provided on the upper side of the movable plate 7, an air flow hose 16 is connected through the base end of the multi-stage cylinder 11 and the base end of the fixed air cylinder 13, and a pedal 12 is fixedly provided at the output end of the multi-stage cylinder 11.

[0036] An L-shaped connecting rod 17 is fixedly provided on the side wall of the adapter plate 20 , and a massage ball 18 is provided at one end of the L-shaped connecting rod 17 away from the adapter plate 20 , and the massage ball 18 is in active contact with the lower wall of the breathable mesh 3 .

[0037] When in use, the patient first sits on the chair 2, and then starts the driving motor 23 and the air pump 25. At this time, the driving motor 23 starts to work, driving the air flow alternating transmission box 22 to rotate. When the strip through hole 27 corresponds to the alternating diversion hole 24 on one side, the air pump 25 inhales air through the strip through hole 27 and the alternating diversion hole 24, and then releases air through the air outlet pipe 26, so that the air flow in the telescopic air cylinder 9 on one side can be transferred to the telescopic air cylinder 9 on the other side. At this time, the telescopic air cylinder 9 on the side where the air is sucked away will shrink, thereby pulling the pedal 12 to move to one side, while the telescopic air cylinder 9 on the other side will stretch after the air is injected, driving the pedal 12 on the other side to move in the opposite direction; as the air flow alternating transmission box 22 rotates continuously, the strip through hole 27 will continuously and alternately dock with the two alternating diversion holes 24, thereby realizing the reciprocating telescopic movement of the two telescopic air cylinders 9 in opposite directions. This process can effectively promote the patient's legs to perform repeated flexion and extension movements;

[0038] When the telescopic cylinder 9 performs reciprocating telescopic motion, it also drives the adapter plate 20 and the push rod 14 to perform reciprocating motion. Under the push and pull action of the push rod 14, the rubber piston 15 repeatedly moves in the fixed cylinder 13. When the rubber piston 15 moves toward the fixed plate 19, the airflow in the fixed cylinder 13 is guided to the multi-stage cylinder 11 through the airflow hose 16, so that the multi-stage cylinder 11 performs extension motion, and then the pedal 12 is used to help the patient complete the vertical upward lifting motion of the left and right legs alternately.

[0039] At the same time, the reciprocating telescopic movement of the telescopic air cylinder 9 also causes the adapter plate 20 and the L-shaped connecting rod 17 to move back and forth accordingly. The movement of the L-shaped connecting rod 17 further drives the massage ball 18 to perform regular massage movements on the patient's buttocks, which can deeply stimulate the patient's buttocks muscles and promote blood circulation, help relieve muscle tension and improve local blood circulation, thereby achieving the desired therapeutic effect.

[0040] In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creatively designing without departing from the purpose of the invention, they should all fall within the scope of protection of the invention.
