• the anti-frost heaving component includes a first connecting rod rotationally connected with the support block and one or more telescopic rods, one end of each of the one or more telescopic rods is fixed on the first connecting rod, a scraping plate is fixed at another end of each of the one or more telescopic rods, and the scraping plate protrudes from an outer wall of the base when the one or more telescopic rods are in an extended state;
• and
• the support plate is in transmission connection with the first connecting rod through a transmission component, and the transmission component converts a vertical linear motion of the support plate into a rotation of the first connecting rod.
