課題を解決することを目的とするものである。[Problems to be Solved by the Invention] Therefore, there are the following problems. As the number of times of pushing the locking piece with the fingertip increases, the fingertip gradually becomes tired, the work efficiency is reduced, and the labor burden is large. When repainting the building frame, the coating on the locking piece may be thicker, in which case the force required to push the locking piece against the bias of the spring increases. It is labor intensive. In a distorted portion such as the upper part of the scaffold, it may be difficult to move the mounting hole along the mounting pin itself, and in conjunction with the above-described operation of pushing the locking piece, It takes time to dismantle the scaffold. The purpose of the present invention is to solve such a problem.

After the operating cylinder 7 is inserted in this manner, the hook-shaped portion 9 at the tip of the operating piece 8 is hooked on the mounting hole 5 of the unit 4 to be removed, and the operating cylinder 7 is moved to the near side in this state. . The mounting hole 5 is drawn by the hook-shaped portion 9 and moves along the two pins for mounting to reach the step portion on the rear side of the locking piece 3, but this step is kept small by the working cylinder 7. Therefore, the mounting hole 5 can be removed from the mounting pin 2 without passing through the mounting hole 5.
