[0032] The support column 31 supports the rotating mechanism 3. When the load-bearing plate 39 rotates laterally, under the action of the first bearing 32, the rotating column 33 rotates, thereby driving the fixed frame 34 to rotate. The fixed frame 34 drives the sleeve 36 and the moving rod 37 to rotate, thereby causing the load-bearing plate 39 to rotate above the running platform of the treadmill body 1. Then, the load-bearing plate 39 rotates longitudinally, causing the waist twisting mechanism 8 to rotate upward. Through the action of the connecting rod 35 and the sleeve 36, the tilt angle of the load-bearing plate 39 can be adjusted up and down, so that the other end of the load-bearing plate 39 can be placed on the platform 11 (the length of the moving rod 37 and the load-bearing plate 39 is greater than the distance between the support column 31 and the platform 11). After the load-bearing plate 39 is placed, the user sits on the disc cover 82. The user twists his waist to drive his hips to rotate. At this time, the disc cover 82 is supported by the third bearing 85 and the rotating rod 84. The lower part can rotate. The rotating rod 84 and the limiting block 86 limit the torsion spring 83. When the cover 82 rotates, it will be resisted by the torsion spring 83, thereby exercising the user's waist. The user's feet are placed on the massage cylinder 75. The second rotating component can make the massage cylinder 75 rotate. The massage protrusions on the massage cylinder 75 can massage the user's feet. When the user bends and straightens his / her legs, the movable rod 73 can rotate under the action of the first rotating component 72. The hanging ring 76 limits the spring 77. When the movable rod 73 moves, the spring 77 is stretched, thereby achieving the purpose of exercising the user's legs. The rope is tied to the hook 52. The rope and back strap are used to reduce the burden on the patient during use. The user then holds the pull ring 54 and pulls it down. Under the action of the elastic pull rope 53, the purpose of exercising the arms is achieved.

[0033] The control mechanism includes two uprights 10 and a control console 9. One end of each upright is fixedly connected to two auxiliary pedals near the front of the treadmill body 1. The bottom of the control console 9 is fixedly connected between the other ends of the two uprights 10. The control console 9 is equipped with a display screen and control buttons.

[0034] The support column 10 supports the control console 9, which can control the start and speed of the treadmill body 1, making it easier for users to carry out rehabilitation training.

[0035] The purification mechanism 4 includes a dustproof mesh frame 41, a frame cover 42, and a negative ion generator 43. The two ends of the dustproof mesh frame 41 are fixedly connected to the adjacent sides of the two columns 10, respectively. A placement groove is provided at the middle of the top of the dustproof mesh frame 41. A hinge is fixedly connected to one end of the frame cover 42. The connecting wall of the hinge is fixedly connected to one side of the groove opening of the placement groove. The negative ion generator 43 is fixedly connected in the placement groove and is electrically connected to the control console 9.

[0036] The dustproof mesh frame 41 has many ventilation holes, which facilitates the negative ion generator 43 to purify the air. The negative ion generator 43 can be inspected and maintained by opening the frame cover 42. The negative ion generator 43 can be started through the control panel 9. The negative ion generator 43 can effectively remove harmful substances such as dust, smoke, pollen, and bacteria from the air, making the air fresher and thus achieving the purpose of purifying the air.
