[0052] When implementing it, Figure 1As shown, the jack 5 is started, and the telescopic end of the jack 5 rises in the vertical direction, driving the connecting plate 41 to move upward. In this process, the connecting rod is pulled by the pull rod 44, so that the inclination angle of the pull rod 44 relative to the base 1 gradually increases. At the same time, the connecting sleeve 42 drives the lattice column standard section 3 to move upward along the outer wall of the fixed end of the jack 5.
