[0030] (2) The rectangular frame of the support leg system and the limit adjustment mechanism work together to form a rigid enclosure at the bottom.

[0031] (3) The design of the ratchet limit device integrated into the drum can realize the one-way rapid tensioning and self-locking of the steel cable. The tension can be released by simply pushing the push rod, which greatly improves the operating efficiency and safety.

[0032] (4) Through the combined design of the adjustable base and the rubber block with grooves, the adjustable base can adaptively compensate for the ground slope error, and the grooves can simultaneously match steel structures of various cross-sectional shapes, achieving a triple tight fit between the device, the components, and the ground.
