The translation plate 18 is slidably connected to the fixed plate 17 through a slider and a slide rail. A groove 19 is opened at the bottom of one end of the translation plate 18. A rack 20 is arranged in the groove 19. The rack 20 is meshed with a gear 21. The gear 21 is rotatably connected to the top surface of the fixed plate 17 through a mounting frame 22. A third rotating rod 23 is connected to the gear 21. A third hand wheel 24 is connected to the other end of the third rotating rod 23.

[0028] The lifting mechanism 2 includes a bracket 201 fixed on the flip plate 305, and a first rotating rod 203 is connected to the bracket 201 through a first bearing seat 204. One end of the first rotating rod 203 passes through the bracket 201 and is connected to a first hand wheel 202. The outer walls of both ends of the first rotating rod 203 are respectively provided with positive threads 205 and negative threads 206. The first rotating rod 203 is threadedly connected to a displacement block 207 through the positive threads 205 and the negative threads 206.

If the end of the limit clamp 307 close to the side of the examination bed is blocked above the rotating shaft 304, there is no need to push the push-pull wrench 16. If the end of the limit clamp 307 close to the side of the examination bed is not blocked above the rotating shaft 304, it is necessary to pull the push-pull handle 16. The adjusting rod 13 pulls the two limit clamps 307 to move horizontally, so that the end of the limit clamp 307 close to the examination bed is blocked above the rotating shaft 304, and then the first hand wheel 202 is turned to raise the translation mechanism and the bed body 1 until the translation mechanism is higher than the examination bed, and then the third hand wheel 24 is turned to make the gear 21 drive the rack 20 to translate, so that the translation plate 18 drives one side end of the bed body 1 to be placed above the examination bed, and then the second hand wheel 7 is turned to drive the flip plate 305 to tilt away from one side of the examination bed through the second connecting rod 9, so that the entire bed body 1 forms an inclined surface, and then the medical staff moves the patient onto the examination bed, and then the various components of the transfer bed are reset.
