[0065] In use, first, the shoe plate 101 is placed in the position of the patient's shoe inner bottom, then, the inflator is inserted into the inflation pipe 204, the inflator pushes the connecting rod 208 to move downward, so that the connecting rod 208 drives the limiting plate 209 to slide, the connecting rod 208 drives the ball 207 to move downward, the airflow input by the inflator enters the vertical air bag 202 and the arc-shaped air bag 203 through the gap between the two baffles 205, the vertical air bag 202 and the arc-shaped air bag 203 are inflated, and it is ensured that the shoe plate 101 closely fits the patient's shoe inner, after the inflation is completed, the inflator is taken out of the inflation pipe 204, the elastic rope 206 rebounds, so that the ball 207 seals the gap between the two baffles 205, and the airflow in the vertical air bag 202 and the arc-shaped air bag 203 is prevented from being discharged.

[0066] Then, the patient places the insole on the shoe plate 101, rotates the pressing plate 212 to fix the insole, and puts the elastic ring 214 into the circular groove 216 on the circular plate 215 to limit the pressing plate 212 and prevent the pressing plate 212 from rotating randomly during use, thereby increasing the comfort of the patient's foot bottom.

[0067] When different acupoints of the patient's foot bottom need to be massaged, the semicircular block 220 is pulled upward, the semicircular block 220 drives the circular plate 218, the circular plate 218 drives the sliding block 221 to slide in the vertical sliding groove 222, when the sliding block 221 slides to the upper end of the vertical sliding groove 222, the semicircular block 220 is rotated, the sliding block 221 slides to the inner wall of the semicircular sliding groove 223, the semicircular sliding groove 223 limits the sliding block 221, the semicircular block 220 massages different acupoints of the patient's foot bottom, and the foot correction of the patient is improved.

[0068] When the height of the arc-shaped pad 105 needs to be adjusted, the pull block 305 is pulled, the pull block 305 drives the connecting shaft 304, the connecting shaft 304 drives the sliding block 303, the second spring 306 is compressed, the sliding block 303 drives the connecting plate 307, the connecting plate 307 drives the bolt 308 to move away from the slot 310 on the disc 309, then, the twist block 225 is twisted, the twist block 225 drives the gear 226 to rotate, the gear 226 drives the rack plate 104 to rotate at the same time, the rack plate 104 drives the arc-shaped pad 105 to move upward, then, the pull block 305 is loosened, the second spring 306 rebounds, the sliding block 303 drives the connecting plate 307, the connecting plate 307 drives the bolt 308 to be inserted into the slot 310 to fix the disc 309, the rack plate 104 is fixed, and thus the height adjustment of the arc-shaped pad 105 is completed, so as to adapt to the legs of different patients.

[0069] When the patient needs to adjust the tightness of the bandage 106, the knob 230 is twisted to drive the rotating rod 229 to rotate, and the rotating rod 229 drives the winding drum 228 to wind the length of the bandage 106, so that the bandage 106 is wound on the surface of the winding drum 228. After the adjustment is completed, since the upper end of the winding drum 228 is fixedly connected with the ratchet wheel 231, when the winding drum 228 rotates, the ratchet wheel 231 can be driven to rotate at the same time, the pawl 233 is inserted into the tooth groove of the ratchet wheel 231 to limit the winding drum 228, so as to prevent the winding drum 228 from rotating at will, so as to complete the adjustment of the tightness of the bandage 106. That is, when the length of the bandage 106 needs to be released, the handle 234 is pulled to drive the pawl 233 and the elastic sheet 236 to be compressed, and after the pawl 233 is separated from the tooth groove of the ratchet wheel 231, the ratchet wheel 231 is released.
