A misuse preventing mechanism disposed on a rotatable child safety seat, the rotatable child safety seat having a base and an installation bracket coupled to the base and configured to support a carrier body, the installation bracket being capable of rotating with respect to the base and having a restraining groove, and the misuse preventing mechanism comprising a lock member disposed on the base and driven to extend into the restraining groove to restrain a rotation angle of the carrier body,
wherein the misuse preventing mechanism further comprises a driving assembly disposed on the base, the driving assembly being adapted to drive the lock member to extend into the restraining groove, and drive the lock member to eject from the restraining groove; and
wherein the driving assembly comprises an operating member, a linkage member, and a guiding pillar, the operating member is pivotally connected to the linkage member, a pivot joint between the operating member and the linkage member slides along an arc hole about the guiding pillar, such that rotation of the operating member drives the lock member to move along a length direction of the lock member.
