Limiting device and medicine cabinet

The utility model relates to a limiting device and a medicine cabinet. The limiting device comprises a suspension rod and a plurality of limiting pieces. The multiple limiting pieces are rotationally arranged on the suspension rod, when the object moves from the lower portion of the suspension rod in the first direction, part of the limiting pieces rotate along with the object, and the non-rotating limiting pieces limit the object to move in the second direction. According to the limiting device, when the articles move from the lower portion of the suspension rod in the first direction, due to the fact that each limiting piece can rotate relative to the suspension rod, different articles can drive the different limiting pieces to rotate according to the different thicknesses of the articles, at the moment, the limiting pieces which do not rotate limit the articles to move in the second direction, and therefore the articles are limited; and medicine management is facilitated. 本申请涉及一种限位装置和药柜，包括悬杆和多个限位件；多个限位件转动设
