When one side of the two half gears 12 is engaged with the sliding tooth plate 13, the other side will no longer be engaged. The sliding tooth plate 13 drives the baffle 14 to move back and forth, controlling the opening and closing of the connecting pipe 6, and the moving time of the baffle 14 each time is the same, so that the amount of liquid medicine passing through the connecting pipe 6 each time is the same.
