[0005] However, it has certain disadvantages: during use, the first lead screw may be accidentally rotated due to external factors (such as wind, vibration, etc.), which causes displacement of the U-shaped block, resulting in inclination of the supporting rod, so that the supporting rod cannot maintain a vertical state, and further causing loosening of the fixing of the building formwork by the supporting rod.
