Lifting platform and locking mechanism thereof

The utility model discloses a lifting platform and a locking mechanism thereof. The locking mechanism comprises a limiting piece fixed to the peripheral side of a rotating component and an embedding piece used for being matched with the limiting piece. A plurality of embedding grooves are formed in the outward side, relative to the rotating part, of the limiting part, and the embedding parts can be correspondingly embedded into the embedding grooves; the embedding piece can move close to or away from the limiting piece in the rotating shaft of the rotating component, and when the embedding piece is close to the limiting piece, the embedding piece is embedded into the embedding groove. When the embedding piece is matched with the limiting piece in an abutting mode, the limiting piece stops rotating under abutting of the embedding piece. According to the technical scheme, the stable locking function is provided, and the structure is simple. 本实用新型公开一种举升平台及其锁止机构，锁止机构包括固定于转动部件周侧的限位件以及用于与限位件配合的嵌合件；限位件相对转动部件的朝外一侧设有多
