A first threaded ring 202 is fixedly connected to the upper portions of both the second water suction pipe 201 and the first water suction pipe 1. A second threaded ring 203 is fixedly connected to the bottom of the first water suction pipe 1. The second threaded ring 203 is threadedly connected to the first threaded ring 202. A protective shell 204 is fixedly connected to the outer side of the second water suction pipe 201. The interior of the protective shell 204 is sleeved with the second threaded ring 203. The protective shell 204 protects the outer side of the first threaded ring 202 to prevent soil from contaminating the outer side of the first threaded ring 202.

[0026] like Figure 2 and Figure 4As shown, the fixing assembly 5 includes a third threaded ring 501, which is threadedly connected to the outer side of the first threaded ring 202 at the top of the first water suction pipe 1. The bottom cover of the third threaded ring 501 is fixedly connected to a connecting plate 502. The side surface of the connecting plate 502 has a plurality of connecting blocks 503 arranged in a circular array. The top of each connecting block 503 is provided with two connecting grooves 504, and the two connecting grooves 504 are symmetrically distributed.
