[0031] A water delivery hole 205 is provided at the top of the stirring shaft 2 , and the water delivery hole 205 is located inside the connecting seat 3 and is enclosed and wrapped by two sets of waterproof bearings.

[0032] The telescopic tube 202 and the water delivery hole 205 are in communication with a pipeline disposed inside the stirring shaft 2 .
