Rod 9, connecting rod 9 is an inverted L-shaped structure, the top of the connecting rod 9 is fixedly connected to the rack 11, the gear 6 is engaged with the rack 11, one side of the box body 2 is fixedly connected to the slide rail 7, the lower end of the connecting rod 9 is slidably connected to the slide rail 7, the top side of the test tube insert 5 is provided with a top cover 20, the top cover 20 is in contact with the tube mouth of the test tube in the corresponding test tube insert 5, the outside of the test tube insert 5 is fixedly connected to the side rod 18, the top side of the side rod 18 is rotatably connected to the screw 19, one end of the screw 19 is threadedly connected to the side of the corresponding top cover 20, a number of leakage holes 23 are provided on the bottom side of the box body 2, and a recovery box 24 is provided at the bottom of the box body 2.

[0026] like Figure 1-5As shown, one end of one connecting shaft 3 passes through the side wall of the box body 2 and is fixedly connected to the gear 6, the slide rail 7 is fixedly connected with a limit rod 8, the lower end of the connecting rod 9 is slidably connected to the limit rod 8, and a spring 10 is fixedly connected between the connecting rod 9 and the slide rail 7. The spring 10 is sleeved on the outside of the limit rod 8, and the end of the connecting rod 9 away from the slide rail 7 is fixedly connected to a fixed rod 12, and the end of the fixed rod 12 is fixedly connected to a top block 13. One side of the box body 2 is fixedly connected to a support frame 14, and the inner side of the support frame 14 is rotatably connected to a rotating shaft 15. One end of the rotating shaft 15 is located at a position corresponding to the top block 13 and is fixedly connected to a biasing member. The edge of the heart wheel 16 and the eccentric wheel 16 abut against the top block 13, and the outer side of the support frame 14 is fixedly connected to the position corresponding to the rotating shaft 15 with a drive motor 17. The output end of the drive motor 17 passes through the support frame 14 and is fixedly connected to one end of the rotating shaft 15. When the drive motor 17 is started, the rotating shaft 15 and the eccentric wheel 16 are driven to rotate, and the reset effect of the spring 10 drives the connecting rod 9 to move back and forth laterally along the slide rail 7, so that the rack 11 moves back and forth laterally and drives the gear 6, the connecting shaft 3, the U-shaped frame 4, and the test tube as a whole to rotate forward and backward by a certain angle, thereby shaking the test tube.

[0027] like Figure 1-5 As shown, the ends of the screw rods 19 are fixedly connected with turning handles 22, and the sides of the top cover 20 and the corresponding side rods 18 are fixedly connected with telescopic rods 21.

The drive motor 17 is started to drive the rotating shaft 15 and the eccentric wheel 16 to rotate. During the rotation process, the eccentric wheel 16 uses its outer edge to push the top block 13 and the solid block 13 to move. The fixed rod 12 and the connecting rod 9 move laterally, and the spring 10 is compressed when it is pushed by the connecting rod 9 and extends when it is not stressed, driving the connecting rod 9 to reset. In this way, the connecting rod 9 can move back and forth laterally along the slide rail 7, so that the rack 11 moves back and forth laterally and drives the gear 6, the connecting shaft 3, the U-shaped frame 4, and the test tube as a whole to rotate forward and backward a certain angle, thereby shaking the test tube. During the experiment, there is a situation where the experimental solution reacts violently and overflows. The box body 2 can receive the liquid overflowing during the shaking process, and the liquid is discharged to the recovery box 24 below through the leakage hole 23, which is convenient for the experimenters to clean up in a centralized manner.
