[0066] When the patient needs to turn over on the other side, the pull plate 209 is pulled upward, and the pull plate 209 drives the sliding block 206 to slide in the sliding groove 207, the first spring 208 is compressed, and the sliding block 206 drives the latch 210 to leave one of the slots 211, then, the handle 205 is pushed, and the handle 205 drives the second rack plate 204 to slide in the rectangular block 110. During the sliding process, the second rack plate 204 can simultaneously drive the two second gears 203 to rotate, and the two second gears 203 respectively drive the corresponding connecting shaft 201 and the first rack plate 111 to rotate in opposite directions, so that one of the first rack plates 111 and the first gear 108 are meshed with each other, and the other first rack plate 111 leaves the tooth groove on the corresponding first gear 108, and the electric push rod 109 is started to turn over the other side of the patient, then, the pull plate 209 is released, the first spring 208 rebounds, and the sliding block 206 The latch pin 210 is driven to be inserted into another slot 211 to restrict the second rack plate 204. When the nursing staff needs to clean the patient's back, the two pulling blocks 220 are pulled at the same time, so that the two pulling blocks 220 are close to each other. The two pulling blocks 220 respectively drive the moving blocks 218 to slide in the moving groove 217, the second spring 219 is compressed, and the moving block 218 drives the insertion rod 221 to leave the two sockets 222 on the drawing plate 213. Then, the drawing plate 213 is pulled, and the drawing plate 213 drives the T-shaped slider 214 to slide in the T-shaped slide groove 215. When the drawing plate 213 slides to fit the inner top wall of the cleaning port 212, the two pulling blocks 220 are released at the same time, the two second springs 219 rebound, and the moving block 218 drives the insertion rod 221 to be inserted into the other two sockets 222, locking the drawing plate 213, and the nursing staff can clean the patient through the cleaning port 212.
