The blocking piece is composed of a pair of longitudinal baffles which are vertically fixed on the base, and the two longitudinal baffles are of V-shaped structures with one side opened so that the reagent bottle can be horizontally pushed into the clamping cavity between the two longitudinal baffles from the opening side of the reagent bottle.
The lower end of the push rod is provided with a push plate of which the lower surface is pressed with the tail end of the core rod of the needle tube.
The sleeve is slidably sleeved on the longitudinal supporting rod, a jacking bolt is vertically arranged on the side wall of the sleeve in a penetrating mode, the inner end of the jacking bolt jacks the longitudinal supporting rod to enable the sleeve to be fixed, the horizontal supporting rod is fixed on the outer wall of the sleeve, and the horizontal supporting rod is enabled to move up and down through the movement of the sleeve.
The puller bolt is a butterfly bolt convenient to screw.
And an anti-skid handle is arranged at the outer end of the operating rod.
The utility model has the advantages of simple structure and simple operation. When a needle tube is used for filtering a small amount of reagent in a laboratory, the needle tube is longitudinally clamped and fixed on the horizontal supporting ring, and the operating rod is rotated downwards, so that the core rod of the needle tube is pressed downwards by the push rod instead of manually pushing the core rod by hand, the operation is more convenient and labor-saving, and the filtering efficiency is improved; in addition, the reagent bottle mouth clamped and fixed in the stopper is always aligned with the liquid outlet end of the needle tube, so that the needle tube and the reagent bottle are ensured to be stably fixed in the whole filtering process, and meanwhile, the filtered reagent is prevented from splashing or not flowing into the reagent bottle, the waste is reduced, and the unnecessary economic loss is avoided.
