The invention discloses a wild-mouth
bottle fixing device, and belongs to the technical field of experiment auxiliary tools. The wild-mouth
bottle fixing device comprises a
bottle body, a bottle plug,a pull disc and a screw-in rod, the
bottleneck part of the bottle body is sleeved with a fixed
lantern ring; the pull disc is arranged on the upper side of the bottle plug; the fixed
lantern ring isconnected with the pull disc by means of upper elastic pull belts which are annularly arranged at intervals; the screw-in rod penetrates through the pull disc and is in threaded connection with the pull disc, and a hook is provided at the end, away from the bottle plug, of the screw-in rod. The screw-in rod is screwed in the pull disc, so that the lower end thereof abuts against the bottle plug; and the upper elastic pull belt applies
pull force to firmly fix the bottle plug, so that the bottle plug is prevented from being disengaged and reagents are prevented from being scattered out due to toppling of the wild-mouth bottle, the waste of the reagents is eradicated, and biochemical
pollution danger is avoided. The screw-in rod is screwed out outwards, the pull disc and the screw-in rod areturned over towards one side, a bottle plug lifting space is reserved, and storing and taking of internal reagents are implemented. The whole wild-mouth bottle can be hung by means of the hook, so that the risk that the wild-mouth bottle topples over due to mistaken touch is effectively eradicated, and hanging, storage and transportation are facilitated.
