[0025] First, the staff rotates the adjusting screw rod 45 in sequence, driving the sleeve rod 47 to drive the second sleeve ring 41 to move backward, thereby pulling the distance between the first sleeve ring 40. When the second sleeve ring 41 moves backward to a suitable position where the distance between it and the first sleeve ring 40 is sufficient to accommodate the gangplank body 2 to be laid, stop rotating the adjusting screw rod 45. Then, pull up the limiting plate 50 to stagger the first sleeve ring 40 and the second sleeve ring 41, and the telescopic spring 55 is compressed accordingly. Next, put a plurality of first sleeve rings 40 and second sleeve rings 41 on the gangplank body 2. After putting them on, adjust the positions of the first sleeve rings 40 and second sleeve rings 41 on the left and right sides to align with the left and right ends of the gangplank body 2 respectively. After alignment, release the limiting plate 50, and the telescopic spring 55 returns to its original state, prompting the limiting plate 50 to move downward to reset and contact the end of the gangplank body 2, thereby limiting the end of the gangplank body 2 and preventing the gangplank body 2 from tipping. Then, reverse the rotation of the adjusting screw rod 45, driving the sleeve rod 47 to drive the second sleeve ring 41 to move forward, thereby shortening the distance between it and the first sleeve ring 40, ensuring the cooperation between the second sleeve ring 41 and the first sleeve ring 40 to firmly hold the gangplank body 2. Then, use a screw gun to drive the prepared screws into the mounting holes 42 in sequence to connect the gangplank body 2, realizing the reinforcement of the gangplank body 2. Next, rotate the first nut 33 downward to disengage from the first screw rod 32, releasing the fixation of the lower buckle ring 30. Then, put the lower buckle ring 30 and the upper buckle ring 31 on the crossbar of the scaffolding bracket 1. After putting them on, rotate the first nut 33 upward to connect with the first screw rod 32 and contact the lower buckle ring 30, thereby fixing the lower buckle ring 30 on the upper buckle ring 31, making the two cooperate to firmly hold the crossbar of the scaffolding bracket 1, realizing the quick fixation of the gangplank body 2. Finally, repeat the above steps to lay an appropriate amount of gangplank bodies 2 on the scaffolding bracket 1.
