[0059] The water pipe joint 32 is connected to the water pipe. After the tap water is collected by the collection tube 31, the collected tap water can flow to the direction of the waterproof bearing 33 and enter the interior of the linkage assembly 4.

[0061] When the locking rod 16 is separated from the limit block 15, the cross plate 11 can be vertically slidably connected to the two sets of guide slide rods 14, so that the cross plate 11 can drive the linkage assembly 4, the diversion assembly 5 and the detection assembly 7, pass through the protective ring 17, and extend into the rock and soil layer. In addition, the protective ring 117 can also use its own counterweight effect to increase the stability of the linkage assembly 4, the diversion assembly 5 and the detection assembly 7 when falling.
