The invention relates to a structure of a funnel chest correction plate. The main structure includes at least one fixing plate body, at least one correction plate body and at least one limiting member. The fixing plate body has a fixing groove, a first limiting portion and At least one second perforation defines a plurality of free ends and an open end, the correction plate body has two guide groove portions and a perforation portion, and defines two open ends and a plurality of closed ends. The combination of the correction plate body and the fixed plate body can use the open end of the guide groove portion to dock with the open end of the fixed groove, and the first limiting portion and the closed end can assist in guiding the coupling action, and finally the limiting member is set on the In the two perforations, the stopper is pressed against the guide groove and cooperates with the closed end to limit the sliding range of the correction plate. This simplifies the combination of the fixed plate and the correction plate, while taking into account the freedom of movement and hygiene issues.本發明為有關一種漏斗胸矯正板之結構，主要結構包括至少一固定板體、至少一矯正板體及至少一限位件，該固定板體上具有一固定槽、一第一限位部及至少一第二穿孔，並界定出複數自由端及一開口端，矯正板體則具有二導槽部及一穿孔部，並界定出二開放端及複數封閉端。矯正板體與固定板體的結合，可利用導槽部的開放端與固定槽的開口端對接，並以第一限位部及封閉端輔助引導該結合動作，最後將限位件設置於第二穿孔中，使限位件抵持於導槽部上，並與封閉端配合作動以限制矯正板體的滑動範圍。藉此簡化固定板體與矯正板體的結合動作，同時兼顧其活動自由度及衛生問題。
