A kind of rocker structure of nursing bed,Its one end is recessed with a room and forms a pivot block,This room is equipped with the first upright embedding part from bottom surface,And a connection-peg has a plug socket,This plug socket one end has an inserting column to grafting what nursing bed,The other end has the second embedding part of corresponding the first embedding part of what configuration； Accordingly,Connection-peg is embedded in the room of what rocker arm with plug socket,And it is corresponding with the first embedding part chimeric with the second embedding part,And plug socket is suppressed fixation towards pivot block by the fixing piece set on what plug socket with one； And a gap is formed between the first embedding part and the second embedding part,And damping material is filled up in what this gap,The resistance for generating and being pivoted relative to each other between pivot block and plug socket is used,And what external force exceed this resistance critical value when form noiseless idling conditions.一種護理床之搖桿結構，其搖臂一端凹設有一容室而形成一樞轉座，此容室自底面設有直立的第一嵌卡部，而一插接頭具有一插接座，此插接座一端具有一用以插接於護理床之插接柱，另一端具有對應於第一嵌卡部配置的第二嵌卡部；據此，插接頭以插接座嵌設於搖臂之容室中，且以第二嵌卡部與第一嵌卡部對應嵌合，並以一設於插接座上之固定件將插接座朝樞轉座壓制固定；而第一嵌卡部與第二嵌卡部之間形成有一間隙，並於此間隙中填滿阻尼材料，藉以產生樞轉座與插接座間相對樞轉的阻力，並於外力超出此阻力的臨界值時形成無聲的空轉狀態。
