When the hip push rod 401 is extended, the hip plate 203, the thigh plate 204 and the back flip plate assembly can be lifted upward. At this time, the back plate 202 will also rise, so that the human body can turn from a sitting position to a standing position. On the contrary, when the hip push rod 401 is retracted, the human body can turn from a standing position to a sitting position.

[0043] Specifically, the lower end of the calf plate 205 is hinged to the upper end of the foot plate 207, and a hinge is welded to the middle part of the side of the calf plate 205. The hinge is connected to the end of the leg push rod 206, and the other end of the leg push rod 206 is connected to the hinge in the middle of the lower support rod at the front end of the chair frame 208. The calf plate 205 can be raised and lowered by the extension and contraction of the leg push rod 206. The foot plate extension rods 213 are vertically welded on both sides of one end of the foot plate 207 close to the calf plate 205. The two foot plate extension rods 213 are respectively hinged to one end of the two foot plate connecting rods 212, and the other ends of the two foot plate connecting rods 212 are hinged to the vertical chair legs at the front end of the chair frame 208.
