Manual and automatic sample injection mode switching device of quantitative fluorescence analyzer

The utility model discloses a manual and automatic sample injection mode switching device of a quantitative fluorescence analyzer. The manual and automatic sample injection mode switching device comprises a sample cell base provided with an accommodating groove, a flowing cuvette and a cuvette mounting seat for fixing the flowing cuvette, an optical assembly is arranged on the side wall of the accommodating groove; the cuvette mounting base is mounted on the guide mechanism, so that the cuvette mounting base can drive the flowing cuvette to be inserted into or moved out of the accommodating groove. The manual and automatic sample injection mode switching device of the quantitative fluorescence analyzer can realize switching between automatic sample injection and manual sample injection, issimple in structure and convenient to operate, and overcomes the defect that only an automatic sample injection mode or a manual sample injection mode quantitative fluorescence analyzer is availablein the prior art. 本实用新型公开了
