The first working position is the position for installing and taking the experimental container 5. At this time, the sliding seat 41 is not located directly below the stirring member 33, so that the experimental container 5 can be conveniently installed or removed. The second working position is the stirring working position of the experimental container 5. At this time, the sliding seat 41 is located directly below the stirring member 33.

The elastic contact bodies can be silicone or other materials. In this way, when the experimental container 5 is inserted into When the experimental container 5 is inserted into the cylindrical mounting groove 43, the bottom of the experimental container 5 presses against the inclined pressing portion 450, so that the arc-shaped limiting block 45 is driven to move toward the inside of the arc-shaped opening groove 47. During this process, the spring member 46 is pressed and has elasticity until the experimental container 5 is inserted into and installed in the cylindrical mounting groove 43. At this time, the vertical pressing portion of the arc-shaped limiting block 45 is in pressing contact with the side wall of the experimental container 5. Since an elastic contact body is provided on the vertical pressing portion, damage to the experimental container 5 can be avoided. Under the action of the spring member 46, the two arc-shaped limiting blocks 45 press and limit the experimental container 5, so that the experimental container 5 is fixed in the cylindrical mounting groove 43. When the experimental container 5 is taken out of the cylindrical mounting groove 43, the arc-shaped limiting block 45 will return to its initial state under the action of the spring member 46.
