[0027] Further, as shown in Figure 1 , Figure 3 and Figure 4 , the middle part of the fixed ring 2 is provided with an adjusting block 3; the adjusting block 3 is fixedly connected to the middle part of the fixed ring 2; the adjusting block 3 is sleeved on the middle part of the electric push rod 11; the middle part of the adjusting block 3 is provided with a threaded hole 31; the inner side wall of the threaded hole 31 is provided with a fixed button 32; the fixed button 32 is screwedly connected to the inner side wall of the threaded hole 31, and during operation, the threaded hole 31 allows the worker to adjust the position of the fixed ring 2 according to the size of the distillation tube, thereby adapting to different distillation tubes and increasing the convenience of the equipment.

[0030] Further, as shown in Figure 1 , Figure 3 and Figure 4As shown in the figure, the side wall of the extrusion block 22 is provided with a rubber sheet 6; the rubber sheet 6 is fixed to the side wall of the extrusion block 22, and in operation, the rubber sheet 6 effectively increases the friction between the rubber sheet 6 and the distillation tube, thereby increasing the fixing effect and the stability of the equipment.

When facing different diameters of distillation tubes, the first spring 18 and the connecting column 19 can effectively clean the distillation tubes of different diameters, thereby improving the use range of the equipment and increasing the applicability of the equipment. When fixing the distillation tube, the distillation tube needs to be inserted into the middle part of the fixing ring 2. When the distillation tube is inserted into the middle part of the fixing ring 2, the extrusion block 22 is extruded and enters the extrusion block 22. Since the magnet 21 and the extrusion block 22 are made of the same material, and there is a repulsive force between the extrusion block 22 and the magnet 21, the two pairs of extrusion blocks 22 extrude the distillation tube under the action of the repulsive force, thereby fixing the distillation tube in the fixing ring 2.
