[0049] The self-adjusting device comprises a first rotating rod 23, a second rotating rod 24 and a connecting assembly, the first rotating rod 23 is movably inserted on the inner wall of the protection box 7, the second rotating rod 24 is movably inserted on the other end of the inner wall of the protection box 7, the first rotating rod 23 and the second rotating rod 24 are movably connected together, two groups of connecting assemblies are arranged in the protection box 7 corresponding to the positions of the first rotating rod 23 and the second rotating rod 24, one end of the two foot stepping plates 6 extends to the inside of the protection box 7, and the two foot stepping plates 6 are fixedly connected with the first rotating rod 23 and the second rotating rod 24 respectively.

[0050] The two connecting assemblies comprise a shaft sleeve 25, a movable sleeve 26, a connecting plate 27, a connecting shaft 28 and a second connecting plate 29, the two shaft sleeves 25 are fixedly connected to the first rotating rod 23 and the second rotating rod 24 respectively, the upper ends of the two shaft sleeves 25 are fixedly connected with the movable sleeves 26, the inner walls of the protective box 7 are movably connected with the two connecting shafts 28, the two ends of the two connecting shafts 28 are fixedly connected with the connecting plates 27 and the second connecting plates 29 respectively, the other ends of the two adjacent second connecting plates 29 are movably connected together through a column, and the two connecting shafts 28 are located on the two sides of the first rotating rod 23 and the second rotating rod 24 respectively.

[0052] The protective box 7 is movably connected with the two connecting assemblies through the two connecting shafts 28.

[0053] Working principle: when the patient lies on the mattress 4 on the bed body 1, the foot part will be in contact with the position of the foot stepping plate 6 at one end of the bed body 1. When the patient needs to pull his own spine, there is no accompanying person, and the patient needs to operate by himself. The patient steps on the foot stepping plate 6 by using his feet. The stepping of the two foot stepping plates 6 will start the self-adjusting device. The self-adjusting device starts the spine lifting device. The activated spine lifting device drives the jack 9 to lift the support flap 2. After the support flap 2 is lifted, the patient's spine is pulled;

[0054] When the patient needs to adjust the spine traction part, first step on the foot stepping plate 6 by using his feet. After the foot stepping plate 6 is stepped on, the first rotating rod 23 and the second rotating rod 24 are driven to rotate. When the first rotating rod 23 is stepped on, the connecting assembly is started. The connecting assembly is rotated with the shaft sleeve 25. The rotation of the shaft sleeve 25 drives the movable sleeve 26 to rotate. After the movable sleeve 26 swings, the limiting column 31 in the movable sleeve 26 swings in the limiting groove 30. The rotation of the movable sleeve 26 drives the connecting plate 27 to swing. The connecting plate 27 and the second connecting plate 29 are fixed by the connecting shaft 28. Therefore, after the connecting plate 27 swings, it rotates around the connecting shaft 28, so that the second connecting plate 29 at the other end also swings up and down with the connecting plate 27. When the connecting assembly at one end is started, the connecting assembly at the other end is also started. After the foot stepping plate 6 at one end is stepped on, the foot stepping plate 6 at the other end swings in the opposite direction due to the symmetry of the two groups. After the two connecting assemblies are started, the two second connecting plates 29 swing up and down. After swinging, the connecting plate 33 moves up and down, so that the swing rod 14 is started by the connecting plate 33. After the self-adjusting device is started, the spine traction device is started. The movement track of the two foot stepping plates 6 forms the movement when walking, so that the legs are exercised to prevent the patient from lying on the bed for a long time to cause the muscle of the lower body to be paralyzed;

[0055] When the self-adjusting device drives the vertebral traction device to start, it drives the swing lever 14 to swing up and down around the rotating shaft 12, and the swing lever 14 is connected with the lever sleeve 13, after the swing lever 14 swings, the lever sleeve 13 rotates slightly, and the lever sleeve 13 has the fixed block 17, the fixed block 17 has the tooth hook 15, after rotating clockwise, the tooth hook 15 will not rotate to the side end because of the block of the blocking block 18, therefore, the lever sleeve 13 will drive the tooth hook 15 to block the gear 11 after rotating clockwise, so as to realize that the tooth hook 15 drives the gear 11 to rotate, after the gear 11 rotates, it drives the rotating disc 10 to rotate, and the rotation of the rotating disc 10 drives the back screw block 21 to rotate, and the interval of the screw block 21 corresponds to the tooth groove 22 on the top rod 9, after the screw block 21 rotates, the tooth groove 22 will gradually rise along the interval of the screw block 21, so as to make the top rod 9 gradually rise, and the top rod 9 is used to make the support rocker plate 2 rise, so that the mattress 4 forms an angle, and the spine can be lifted;

[0056] When it is needed to put down the top rod 9, the hand position is moved to the edge of the bed body 1 to move the adjusting rod 35 to the side end, so that the adjusting rod 35 drives the moving seat 34 to move to the side end, and the moving seat 34 drives the rotating disc 10 to move to the side end, at this time, the rotating disc 10 drives the support sleeve 16 to move to the side end, so that the slider 19 on the side end of the support sleeve 16 is separated from the original sliding groove 20 and is moved to the sliding groove 20 on the other side, and at this time, the screw block 21 is also separated from the tooth groove 22, loses the support of the screw block 21, and the tooth groove 22 on the top rod 9 also loses the support force, so that the top rod 9 falls, and thus the mattress 4 returns to the original state.

[0057] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
