[0068] Working principle of the present application: Height adjustment principle: the second telescopic member 22 is extended outward, and since the output shaft of the second telescopic member 22 always has an included angle with the lifting frame 38, the lifting frame 38 is pushed obliquely downward. The first connecting rod 601 has one end hinged to the lifting frame 38, and the hinged rod 603 arranged on the first connecting rod 601 is hinged to the bottom frame 101. Since the bottom frame 101 is fixed as a whole, the first connecting rod 601 rotates around the hinged point of the hinged rod 603 and the bottom frame 101 as the center, and the first telescopic rod drives the support frame 102 and the top frame 103 to be lifted upward during the rotation of the first connecting rod 601, thereby realizing overall height adjustment. Transfer: first, the third driving assembly 18 drives the transfer plate 2 to extend outward and approach the patient. After being moved to the position, the second driving assembly 8 drives the first movable plate 1001 and the second movable plate 1004 to be opened at the same time toward the longitudinal two ends of the bed body 1, thereby driving the first movable plate 1001 and the second movable plate 1004 to be unfolded, inserting the first movable plate 1001 or the second movable plate 1004 into the back of the patient, starting the first driving assembly 7 to drive the transfer belt 301 to rotate and transfer the patient to the transfer plate 2, and turning up the first movable plate 1001 and the second movable plate 1004 to limit the two ends of the transfer plate 2. The operation of transferring the patient from the transfer bed to the sickbed is opposite to the above, which will not be described herein.
