Specifically, the rotating handle 340 is provided to facilitate the operation of the screw 350 by the user. In operation, when the water pump 100 is required to be lifted up, the rotating handle 340 is rotated in the first direction, so that the screw 350 is driven to rotate synchronously, and the lifting rod 310 is rotated up. When the water pump 100 is required to be lowered, the rotating handle 340 is rotated in the second direction, thereby driving the screw 350 to rotate synchronously, and thus the lifting lever 310 is rotated downward.

In some embodiments of the utility model, as shown in fig. 1 and 2, the operating mechanism further includes a sleeve 330. The shaft sleeve 330 is disposed at the top of the receiving cavity, and the screw 350 can be inserted into the shaft sleeve 330.
