[0014] Through the above technical solution, the adjustment component can adjust the position of the adjustment airbag to achieve the dispersion of body pressure, which can reduce the pressure in the area and prevent or reduce the occurrence of pressure sores.

[0015] Furthermore, an air pump is provided on one side of the frame close to the fixing box, the output end of the air pump is connected to a connecting pipe, one end of the connecting pipe is connected to a plurality of shunt pipes, and the plurality of shunt pipes are respectively connected to corresponding regulating airbags.

[0029] The support assembly includes a fixed box 8, a motor 9 is arranged inside the fixed box 8, a threaded rod 10 is fixedly connected to the output end of the motor 9, a slider 11 is threadedly connected to the outer wall of the threaded rod 10, and a placement frame 13 is arranged on the top of the slider 11.

[0030] Reference Figure 1-Figure 2 The top of the slider 11 is fixedly connected to two support rods 12, the tops of the two support rods 12 are fixedly connected to the placement frame 13, and two slide grooves are opened inside the fixed box 8, and the two ends of the slider 11 are slidably connected to the corresponding slide grooves respectively.

[0031] When the slider 11 slides in the slide groove inside the fixed box 8, it drives the placement frame 13 on the top of the support rod 12 to move up and down, which can effectively reduce the contact between the heel and the frame 1, reduce the continuous stimulation of the skin, and help prevent the occurrence of pressure sores.

[0032] Reference Figure 1-Figure 3 , both ends of the frame 1 are provided with movable grooves 2, and the inner sides of the two movable grooves 2 are provided with adjustment components, the adjustment components include adjustment airbags 4, the number of adjustment airbags 4 is set to multiple, and both ends of the multiple adjustment airbags 4 are fixedly connected with connecting blocks 3, and the inner sides of the two movable grooves 2 are provided with multiple friction blocks, and each connecting block 3 is slidably connected to the corresponding movable groove 2 respectively.

[0033] By setting the adjustment component, the position of the adjustment airbag 4 can be adjusted. Specifically, when effective support is needed for different parts of the legs, the adjustment airbag 4 is moved, and the connecting block 3 is moved inside the moving groove 2. The friction block can provide a certain friction force, so that the adjustment airbag 4 can move only when external force is applied. The supporting part can be adjusted to achieve the dispersion of body pressure, which can reduce the pressure in the area and prevent or reduce the occurrence of pressure sores.
