[0029] First, the reactor 2 is placed between the two support frames 12, and then, according to the size of the reactor 2, the two support frames 12 are driven to move closer or farther by the first driving component 15 so that the two clamping components 13 can be clamped on the reactor 2. In this way, the driving of the first driving component 15 can achieve stable clamping of reactors 2 of different sizes, reduce the risk of accidental collision and tilting, protect the safety of experimental samples and equipment, reduce the risk during the experiment, and also facilitate operators to compare and verify different samples on the same reactor mechanism, thereby reducing operational errors; after clamping the reactor 2, the two clamping components 13 are synchronously flipped by the two flipping components 14, so that the two clamping components 13 can drive the reactor 2 to flip synchronously, so that the materials in the reactor 2 can be shaken, and the samples in the reactor 2 are effectively promoted to be evenly mixed, thereby accelerating the mixing and reaction process of the samples and reagents in the reactor 2, and ensuring that they are evenly treated during the experiment, thereby improving the reaction efficiency and detection accuracy, and also making it easier to clean and maintain through flipping, reducing the accumulation of residues, thereby bringing convenience and benefits to experimental operations and sample comparisons.

[0030] Among them, a horizontal slide groove is arranged on the upper side of the base 11, and the bottom of the support frame 12 is slidably arranged in the horizontal slide groove to achieve sliding cooperation.

[0031] Among the optional solutions of this embodiment, it is more preferred to refer to Figure 4Each clamping assembly 13 includes a second driving assembly 131 and two clamping flaps 132, and the second driving assembly 131 is connected to the corresponding flip assembly 14; the second driving assembly 131 is connected to the two clamping flaps 132, and is used to drive the two clamping flaps 132 to move closer or farther away, and the distance between the two clamping flaps 132 is further regulated by the second driving assembly 131 to meet the clamping of reactors 2 of different specifications in a larger range; specifically, the moving direction of the two clamping flaps 132 is parallel to the diameter direction of the reactor 2, wherein the moving direction of the two support frames 12 can be perpendicular to the moving direction of the two clamping flaps 132, which is equivalent to adapting to the specifications of the reactor 2 in two horizontal directions perpendicular to the reactor 2.

[0032] Among the optional solutions of this embodiment, it is more preferred to refer to Figure 4 Each second driving assembly 131 includes a clamping plate 133, a bidirectional screw 134 and a driving gear 135.

In this way, the main gear 136 is rotated by external manpower or electric power to drive the bidirectional screw 134 to rotate through the slave gear, thereby driving the two clamping petals 132 to slide relative to the clamping plate 133 to get closer or farther away.

[0033] In addition, the second drive component 131 can also be set as other mechanisms that can realize the movement of the clamping flap 132, such as an electric telescopic mechanism, which realizes the linear movement of the clamping flap 132 through electric control. It should be noted that the type of the second drive component 131 is not limited to the above, and other structures that can drive the clamping flap 132 to move reciprocatingly in a linear manner can also be used.

[0034] In the optional scheme of this embodiment, it is more preferred that the inner side surface of each clamping petal 132 is used to match the outer peripheral shape of the reactor 2; correspondingly, the inner side surface is set to be arc-shaped, and a rubber pad is provided on the inner side surface to improve the clamping stability while avoiding damage to the reactor 2 by clamping.

[0042] Among the optional solutions of this embodiment, it is more preferred to refer to Figure 3The transmission assembly 152 includes a first transmission rod 153 and two second transmission rods 154.
