When materials in a container such as a three-neck flask are required to be stirred, a stirring device stretches into the bottle mouth of the container, so that the lower cock 400 is clamped at the bottle mouth of the container, at the moment, the stirring rod 100 penetrating through the lower cock 400 stretches into the container, and then the stirring rod 100 is driven to rotate around the axis of the stirring rod 100 so as to stir the materials in the container.

In this embodiment, the inner diameter of the inner ring of the bearing 500 is equal to the outer diameter of the stirring rod 100, and the outer diameter of the stirring rod 100 of the inner diameter of the sealing ring 600 is equal, so that both the bearing 500 and the sealing ring 600 are tightly matched with the stirring rod 100.

In this embodiment, when the stirring device is used to stir the materials in the container such as the three-neck flask, the lower cock 400 of the stirring device is clamped at the bottle mouth of the container, so as to avoid that the upper cock 200, the connecting cock 300 and the lower cock 400 extend below the liquid level in the container and directly contact the materials in the container; in addition, the sealing process is performed on the clamping position of the lower cock 400 at the bottle mouth of the container before the stirring process is performed; because the stirring rod 100 is sleeved with the sealing ring 600, the material in the container is prevented from being sputtered outside the container.

The lower cock 400 is made of polytetrafluoroethylene material, and in particular, polytetrafluoroethylene has anti-corrosion performance, so that the lower cock 400 is prevented from being corroded by material being sputtered onto the lower cock 400 when corrosive material is stirred by the stirring device. Further, the upper plug 200 and the connection plug 300 are also made of polytetrafluoroethylene.

Referring to fig. 1 and 3-5, the upper cock 200, the connection plug 300, and the lower cock 400 are all of a truncated cone structure having a top size greater than a bottom size.
