1. A locking device for silicone packings of household bean milk and bean curd makers, the makers individually having a housing with a cavity, a main body provided on an upper portion of the housing for opening and closing the housing, and a silicone packing attached to an underside of the main body so as to prevent leakage of water into the main body and to absorb shock, in use, the locking device, comprising: a) a plurality of protrusions provided on an upper surface of the silicone packing; b) a plurality of locking depressions provided on a lower portion of the main body and corresponding to the protrusions, so that the protrusions are inserted into the corresponding locking depressions, in use; c) each of the locking depressions having a cross-section different from that of each of the protrusions, thus allowing the protrusions to be deformed to have an elastic restoring force, when the protrusions are inserted into the corresponding locking depressions, in use; d) a boss provided in each of the locking depressions, thus causing the protrusions to be deformed to have an elastic restoring force when the protrusions are inserted into the corresponding locking depressions, in use; and e) an air hole provided to allow the protrusions to be easily inserted into the corresponding locking depressions.
