The upper ends of the two sliders 13 are rotatably connected with the first connecting rod 14, and the lower ends of the two sliders 13 are rotatably connected with the second connecting rod 15. The two first connecting rods 14 and the two second connecting rods 15 are respectively rotatably connected with the two sleeves 5, and the two first connecting rods 14 and the two second connecting rods 15 form a diamond mechanism; a through hole vertically slidably connected to the bracket 2 is opened in the middle of the support block 4, and a fastening screw for fixing the support block 4 is threadedly connected to one side of the support block 4, and a worm gear 16 is coaxially fixedly connected to the winding drum 7, and the worm gear 16 is meshed with a worm 17, and the worm gear 16 and the worm 17 are both rotatably connected to the support block 4.

The base 1 is used to support the bracket 2. A hydraulic telescopic rod can be provided between the base 1 and the bracket 2 to adjust the height of the seat plate 3, so as to improve the comfort of the patient during use. The support block 4 is located on the bracket 2, and the support block 4 is fixedly connected to the bracket 2. Due to the different heights and body shapes of different patients, the support block 4 can be fixed to the bracket 2 by means of fastening screws, so that the two fixing frames 6 are located at a suitable height of the patient's upper body. There are arc-shaped protective blocks on both sides of the fixing frame 6, and there are straps on both sides of the fixing frame 6. The straps and the fixing frame 6 cooperate to form a closed structure for fixing the position above the lumbar spine. The two fixing frames 6 move relative to each other under the action of the diamond mechanism, and the movement of the traction belt 9 and the fixing frame 6 is synchronized.
