When the patient lies on the elastic component 203, the support plate 202 will be pressed down, causing the limiting sleeve 2012 to slide down inside the auxiliary rod 2011, and the rubber pad 2037 will be pressed down by the elastic sheet 2034 and the spring 2036. Spring 1 2014 causes the limiting sleeve 2012 to stop sliding down after sliding to a certain extent. When the limiting sleeve 2012 drives the piston 1 213 to move up and down inside the auxiliary rod 211, it will drive the electromorphic fluid inside the auxiliary rod 2011 to flow out or flow in. When the patient lies down, the electrode is energized to fix the electromorphic fluid, thereby fixing the adjustment component 201, so that the multiple elastic components 203 on the upper part form a groove that fits the patient's body, so that the elderly with hunchbacks can also lie down well, effectively preventing the patient from moving around.
