Then, the bent end of the moisture measuring tube 7 is connected to the mouth of the round-bottom flask 9, and the condenser tube 8 is connected to the moisture measuring tube 7.

[0030] A second through hole is provided on one side of the connecting block 5. The inner surface of the second through hole is adapted to the outer surface of one side of the clamping plate 6. One side of the clamping plate 6 is threaded into the inside of the second through hole.
