The movable frame 5 moves longitudinally along the surface of the slide bar 4, shortens and adjusts the horizontal distance between the pillow 6 and the wrist clamp assembly 8, and starts the electromagnetic suction cup 10. The iron core inside the electromagnetic suction cup 10 is magnetized, and suction is generated between the magnetized iron core and the iron sheet 2. Then the electromagnetic suction cup 10 drives the moving plate 9 and the slider 12 to move along the slide groove 11 until the electromagnetic suction cup 10 is adsorbed on the surface of the iron sheet 2, and the fixing of the moving plate 9 is completed. The two moving plates 9 fixed by the electromagnetic suction cup 10 fix the movable frame 5 through the slider 12.

[0027] The bottom ends of the two sliders 12 are fixedly connected to the bottom ends of the two movable plates 9 respectively, through holes are provided on the surfaces of the two sliders 12, the inner wall of the movable frame 5 is slidably connected to the surface of the bed body 1, a side plate 13 is fixedly provided on one side of the top of the movable frame 5, and the surfaces of the two iron sheets 2 are coated with anti-rust paint. The sliders 12 will slide along the surface of the guide rod 72 through the through holes.

[0034] When in use, the movable frame 5 is pulled by the handle and the side plate 13, and the movable frame 5 slides along the surface of the bed body 1. The movable frame 5 is moved, and the movable frame 5 drives the pillow 6 to move. The movable frame 5 moves longitudinally along the surface of the slide bar 4, shortening and adjusting the horizontal distance between the pillow 6 and the wrist clamp assembly 8, and selecting the position where the pillow 6 stays according to the patient's height, and then starting the two electromagnetic suction cups 10, the iron core inside the electromagnetic suction cup 10 is magnetized, and the magnetized iron core and the iron sheet 2 generate suction force. At this time, the electromagnetic suction cup 10 drives the movable plate 9 and the slider 12 to move along the slide groove 11 until the electromagnetic suction cup 10 is adsorbed on the surface of the iron sheet 2, completing the fixation of the electromagnetic suction cup 10, and the two electromagnetic suction cups 10 fix the movable frame 5 through the movable plate 9, the slider 12 and the slide groove 11, completing the fixation of the pillow 6, thereby adjusting the position of the pillow 6 and enhancing practicality;
