The protective frame 902 located in the hollow space of the installation bin 901 provides protection for the surface of the flexible soft cable 8. After the upper end of the installation bin 901 is damaged by the user after being stepped on, the over-squeezed protective frame 902 synchronously squeezes the internal gas of the bellows telescopic tube 906 to enter the ventilation duct 904 and push the bellows connected to the telescopic top rod 903 to extend, so that the telescopic top rod 903 supports the bottom end of the protective frame 902 to maintain stability, avoiding the protective frame 902 from excessively descending and squeezing the flexible soft cable 8, causing the flexible soft cable 8 to be damaged, thereby extending the service life and increasing the overall practicality.
