When the rotating frame 3 is used, the U-shaped sliding seat 2-1 can drive the two horizontal sliding frames 3-4 to move back and forth when moving back and forth, and the two worms 2-15 do circular motion around the axis of the external thread rod 2-9, so that the circular ring 3-1 is driven to rotate between the two arc-shaped plates 2-16. When the test tube fixing seats 4 are used, the four test tube fixing seats 4 can simultaneously clamp four test tubes, and the four test tube fixing seats 4 respectively rotate on the two horizontal sliding frames 3-4 to drive the test tubes to swing; four test tubes on four test tube fixing seats 4 can be driven to vibrate back and forth simultaneously when the U-shaped sliding seat 2-1 moves back and forth, the ring 3-1 is driven to drive the test tubes on the four test tube fixing seats 4 to do centrifugal motion when rotating, two worms 2-15 can drive two swinging driving pieces 5 to work when rotating, the two swinging driving pieces 5 drive the test tubes on the four test tube fixing seats 4 to vibrate in a horizontal swinging mode simultaneously, the effect of driving a plurality of test tubes to vibrate in a multidimensional manner simultaneously is achieved, chemical liquid in the test tubes can be fully fused, the full progress of reaction is guaranteed, the experiment effect is achieved, and meanwhile, the plurality of test tubes vibrate simultaneously, so that the contrast test is convenient to carry out.
