[0031] Specifically, the two insulation sleeves are insulation sleeve 1 3 and insulation sleeve 2 4, which are tightly attached to the outer wall of the buried pipe body 2 connected to the heat exchanger body 1. The purpose of this step is to minimize the influence of groundwater temperature on the buried pipe and reduce heat loss. Next, the outer wall of the insulation sleeve 1 3 is operated to rotate, and the rotation of the rotating shaft 5 drives the rotating plate 6 to rotate. The rotating plate 6 slides into the interior of the bracket 7, and the slider 8 is pulled to move with the block 9. During the movement, the slider 8 is released, so that the block 9 is driven by the reaction force of the telescopic rod 10 and the spring 11 to be stuck in the interior of the movable plate.
