[0008] The utility model discloses a kind of mobile scaffold with high stability for construction, which moves upward by pulling the handle, thereby driving the two vertical plates to disengage from the corresponding positioning grooves, and then rotating the handle, and rotating the vertical plates and the vertical grooves through the cooperation of the turntable and the screw rod, the screw rod drives the horizontal plate downward through the thread transmission of the horizontal plate and under the guidance of the support column and the U-shaped plate, the horizontal plate drives the four bottom plates to move downward through the four supporting bent plates, so that the four bottom plates are in contact with the ground, and the scaffold is propped up, so that the four universal wheels are off the ground, and then the handle is released, so that the vertical plates move downward under the action of the compression springs and are stuck in the positioning grooves, so as to realize the positioning of the horizontal plates, thereby preventing the rolling of the universal wheels from affecting the stability and safety of the scaffold;

[0009] The utility model has a reasonable structural design. The rolling of the universal wheels facilitates the movement of the scaffolding, thereby improving the flexibility of use. The four bottom plates are driven downward by the cross plate to make them contact with the ground to prop up the scaffolding, so that the four universal wheels are separated from the ground, thereby preventing the rolling of the universal wheels from affecting the stability and safety of the scaffolding, and the reliability is high.
