In order to allow the sliding tube 11 to be moved down better when the agitating shaft 2 is rotated so that the above-mentioned water feed hole 10 is aligned and communicated with the drainage hole 1102 more accurately, the longer the sliding tube 11 is, the better the sliding velocity of the sliding tube 11 caused by gravity is increased. The design of the sliding pipe 11 is characterized in that when the stirring hook 201 rotates around a vertical axis in a posture of up and down, left and right, the larger the rotating speed is, the more the sliding pipe 11 is tightly attached to the bottom end step of the inner reaming section, so that the position state of the main water supply hole 10 and the corresponding drainage hole 1102 which are aligned and communicated is more stable, the conduction state is ensured to be maintained, and the stirring machine is particularly suitable for a stirring machine with a large stirring range, and the size advantage of the stirring rod 2 is fully utilized.
