The invention discloses a dual-purpose test tube oscillator. The dual-purpose test tube oscillator comprises a worktable, wherein a rectangular groove is formed in the upper surface of the worktable;a circular groove 1 is formed in the inner left side surface of the rectangular groove; a miniature electric push rod 1 of which the pushing end is rightward is arranged on the inner right side surface of the circular groove 1; a miniature electric rotating rod 1 of which the rotating end is rightward is arranged at the pushing end of the miniature electric push rod 1; the rotating end of the miniature electric rotating rod 1 is sleeved by a limiting block; a notch is formed in the inner right side surface of the rectangular groove; a circular groove 2 is formed in the inner lower surface of the notch; a miniature electric push rod 2 of which the pushing end is upward is arranged on the inner lower surface of the circular groove 2. The dual-purpose test tube oscillator has the beneficial effects as follows: the dual-purpose test tube oscillator is not only applicable to test tubes, but also applicable to dissolution of an immobilized reagent, so that the dual-purpose effect is achieved; in addition, a semi-automatic state is achieved, timing is achieved, and the test tubes are convenient to take.
