A rotating mechanism is provided at the other end of the second rotating shaft 19, and the second rotating shaft 19 can rotate with the second bevel gear 22 through the first bevel gear 21, and then the second bevel gear 22 drives the screw 25 to spirally rotate on the inner side of the moving rod 24, so that the moving rod 24 stretches the patient's body through the strap 3, thereby realizing auxiliary treatment of the patient's lumbar vertebra, and at the same time, a strap 3 is also provided at one end of the traction frame 2.

[0025] As a further improvement of the present invention, Figure 2 、 Figure 3 and Figure 4 As shown, the rotation mechanism includes a connecting cover 4 fixedly connected to the bed body 1, the inner side of the connecting cover 4 is rotatably connected to a driving wheel 10 and a driven wheel 12, and the driven wheel 12 is fixedly connected to a second rotating shaft 19, and the second rotating shaft 19 is rotatably connected to the connecting cover 4. A belt 11 is provided on the outer side of the driving wheel 10 and the driven wheel 12, and one end of the belt 11 is provided with a tensioning assembly. One end of the driving wheel 10 is fixedly connected to a first rotating shaft 6, and the other end of the first rotating shaft 6 is fixedly connected to a handwheel 5. A limiting assembly is provided at one end of the first rotating shaft 6. The handwheel 5 is moved in the horizontal direction by the first rotating shaft 6, so that the patient can adjust the use position of the handwheel 5 according to his own usage needs, so that the patient can use the arm to forcefully turn the handwheel 5, thereby facilitating the patient's use and ensuring the traction effect. At the same time, the handwheel 5 rotates with the first rotating shaft 6, and then the first rotating shaft 6 drives the driving wheel 10, so that the driving wheel 10 rotates with the driven wheel 12 through the belt 11, and then the driven wheel 12 rotates with the second rotating shaft 19.

[0026] As a further improvement of the present invention, Figure 4 、 Figure 5As shown, the tensioning assembly includes a support frame 15 fixedly connected to the connecting cover 4, and a guide column 16 is slidably connected to the inner side of the support frame 15.

[0028] As a further improvement of the present invention, Figure 2 、 Figure 3 and Figure 4 When the hand wheel 5 is in a proper position, the threaded ring 8 and the connecting cover 4 are tightly fitted together, and the friction between the threaded ring 8 and the connecting cover 4 is used to limit and fix the threaded ring 8 and the slider 7, thereby ensuring that the position of the hand wheel 5 does not change when in use; at the same time, a sliding groove for the smooth movement of the bolt 9 and the slider 7 is respectively provided at the top and side ends of the connecting cover 4. By limiting the length of the sliding groove according to actual design requirements, no matter which end of the sliding groove the slider 7 moves to, the angle between the belt 11 and the driving pulley 10 and the driven pulley 12 is greater than 120 degrees.

[0029] Working process: the patient first lies on the bed and adjusts the position of the hand wheel 5 according to the best position of his arm using the hand wheel 5. First, the threaded ring 8 is separated from the connecting cover 4, and then the slider 7 is moved horizontally on the inner side of the connecting cover 4 with the driving wheel 10 through the first rotating shaft 6. At the same time, when the driving wheel 10 moves, the end of the belt 11 close to the driving wheel 10 will also move accordingly, and as the end of the belt 11 moves, the tensioning wheel 13 will also move accordingly in the vertical direction. When the hand wheel 5 is adjusted to the appropriate position, the patient makes the threaded ring 8 fit tightly with the connecting cover 4, and the threaded ring 8, bolt 9, slider 7, first rotating shaft 6 and hand wheel 5 are adjusted by the friction between the threaded ring 8 and the connecting cover 4. The limit is fixed to ensure that the position of the handwheel 5 does not change when it is used. After the patient lies on the bed 1, the patient's shoulders and waist are tied by the straps 3 at both ends of the bed 1. Then the patient rotates the first rotating shaft 6 with the handwheel 5, and then the first rotating shaft 6 rotates the driving wheel 10, so that the driving wheel 10 rotates with the driven wheel 12 through the belt 11, and then the driven wheel 12 rotates with the second rotating shaft 19. The second rotating shaft 19 can rotate with the second bevel gear 22 through the first bevel gear 21, and then the second bevel gear 22 drives the screw 25 to rotate spirally on the inner side of the moving rod 24, so that the moving rod 24 is tensioned on the patient's body through the straps 3, thereby achieving auxiliary treatment of the patient's lumbar vertebra.
