The utility model discloses a cup set anti -backoff device of mixer, including cup set, anti -backoff rod and elastic part, cup set includes mixing cup and cup seat, and the lower part of mixing cup is fixedly connected through the mode of thread or along one direction rotation jointing with cup seat, and the anti -backoff limiting portion is formed on mixing cup, and anti -backoff rod is installed on cup seat through elastic part, and when cup set leans against mixer host computer, anti -backoff rod is lifted under the action of external force, and its side leans against the side of anti -backoff limiting portion to restrict mixing cup and cup seat from separating, when cup set leaves mixer host computer, anti -backoff rod leaves the side of anti -backoff limiting portion under the action of elastic part, and mixing cup and cup seat can normally separate. The utility model adopts the mode that anti -backoff rod leans against the side of anti -backoff limiting portion to limit and prevent the anti -backoff between mixing cup and cup seat, and the anti -backoff mode is stable, improves the stop effect of cup set anti -backoff device, and guarantees the safety of practical mixer.
