The right end of the motor mounting plate 22 is fixedly connected to the left end of the position sensor fixing block 24. The right end of the position sensor fixing block 24 is fixedly connected to the left end of the position sensor mounting plate 9.

The inner cavity of the tracheal connector 6 is controlled to be connected to positive pressure, and the inner cavity of the suction head 3 connected to the inner cavity of the tracheal connector 6 is also connected to positive pressure. The freezing tube 2 is blown away from the opening at the lower end of the suction head 3 and falls on the designated placement position, completing the release action of the freezing tube 2.
