) Is a multiplying factor of (2).
When switching between different connection pipes 82, the water in the connection pipe 82 needs to be removed, and the following measures are taken in this embodiment:

The working principle of the above technical solution is that when switching, the test electric valve 93 is closed first, and then the rotation angle K of the third driving component 103 is controlled, where the rotation angle K is determined according to the position of the last used connecting pipe 82 and the relative position of the currently used connecting pipe 82, for example, the number of connecting pipes 82 is 6, then the included angle between two adjacent connecting pipes 82 is 60 degrees, then if the relative position is 1, then the rotation is 120 degrees, and so on.
