[0032] Specifically, such as Figure 1 and Figure 2 As shown, the connecting rod 3 is fixed to the guardrail 2 by the connecting rope 24. Pulling the pull rod on the connecting sleeve 23 causes the connecting sleeve 23 to compress the limiting spring 20, thereby opening the clamp 22 through the connecting rod 3. Then, the infusion tube or other treatment equipment cable is placed between the clamps 22. After placement, the pull rod is released to limit the infusion tube and cable. Using the clamp 22 to limit the infusion tube and cable not only prevents the infusion tube and cable from being placed randomly on the bed board 1 and affecting the appearance, but also facilitates the sliding of the infusion tube and cable between the clamps 22.

[0033] Working Principle: In use, the connecting rod 3 is fixed to the guardrail 2 via the connecting rope 24. Pulling the pull rod on the connecting sleeve 23 causes the connecting sleeve 23 to compress the limiting spring 20, thus opening the clamp 22 via the connecting rod 3. Then, the infusion tube or cables from other treatment equipment are placed between the clamps 22. After placement, the pull rod is released, and the clamp 22 limits the infusion tube and cables. Using the clamp 22 to limit the infusion tube and cables not only prevents them from being placed haphazardly on the bed board 1, affecting aesthetics, but also facilitates the sliding of the infusion tube and cables between the clamps 22. Pulling the pull ring 7 at the bottom of the connecting block 8 activates the return spring 9, which can improve elasticity and strengthen the user's arm muscles. The pull ring 7 at the bottom of the suspension rope 11 facilitates the user getting up. Adjusting the pull ring 7 is required. When positioning, unscrew the fixing bolt 25 from the inside of the adjustment hole 14 to loosen the movable plate 10. After the movable plate 10 is loosened, slide it inside the fixed plate 12 to adjust the position of the pull ring 7. After adjustment, screw the fixing bolt 25 back into the adjustment hole 14 to fix the movable plate 10. The hydraulic cylinder 4 can drive the caster 18 to rise and fall through the mounting plate 17, thus facilitating the movement of the nursing bed. When it is necessary to adjust the angle of the adjustment plate 5 to support the patient's upper body, turn the handle 28. The handle 28 drives the rotating shaft 27 to rotate through the worm 29 and worm wheel 26. The rotation of the rotating shaft 27 can adjust the angle of the adjustment plate 5 as needed. Using the worm wheel 26 and worm 29 to adjust the angle of the adjustment plate 5 can lock the adjustment plate 5 to prevent the rotating shaft 27 from accidentally rotating the adjustment plate 5.
