[0002] Geological disasters are a kind of natural disasters, such as earthquakes that occur all year round, which belong to geological disasters and can pose a great threat to people's lives and property safety. Most geological disasters mainly occur in mountainous areas, such as flash floods, landslides, debris flows and landslides, etc. Such geological disasters often cause large geological vibrations when they occur. In order to reduce the loss of geological disasters, it is necessary to set up surveying and mapping devices in areas where geological disasters frequently occur to achieve monitoring and early warning.

[0003] A geological disaster early warning device is disclosed in Chinese Utility Model Patent No. CN215450392U, which comprises an early warning box with a heat dissipation mechanism inside, a protection mechanism on the top of the early warning box, and two fastening mechanisms on both sides of the early warning box. The fastening mechanism includes a fixed block welded to the side wall of the early warning box, a threaded rod screwed onto the fixed block, a spiral drill rod coaxially welded to the outer wall of the bottom end of the threaded rod, and a hand wheel sleeved on the threaded rod.

[0004] The above technology realizes the fixation between the early warning device and the soil layer by inserting four spiral drill rods into the soil layer. The spiral drill rod only contacts the soil layer in the vertical direction, and the grip ability is poor. After the early warning box is impacted by external forces such as wild animals, the stability of the connection between the early warning device and the soil layer is easily affected. SUMMARY
