なうことができないという問題がある。In the conventional structure for mounting a drop lock, the fall lock always falls to the locking position by its own weight. The lock must be pushed up and held to the unlocking position artificially, and therefore, when installing or removing the scaffold, the workers must operate the falling locks of the hook devices on both sides separately. Therefore, there is a problem that work cannot be performed by one worker.

When the lower end of the falling tablet 4 is pushed up to bring the falling tablet 4 to the highest unlocked position, the lower end 10b of the upper slot 10 is
The lower end 11b of the lower slot 11 abuts on the pin 6, the lower end of the falling tablet 4 projects into the upper part of the locking recess 9 and abuts on the horizontal shallow A. The main body 3 is lifted from above the horizontal shallow A and floats. At this time, the falling tablet 4
At the lower end of the locking recess 9 escapes rearward.

The falling tablet 4 has its lower end abutting on the lower outer surface of the horizontal shallow A. Of the upper locking hole 10 is engaged with the pin 5 and the lower end of the falling lock 4 contacts the shallow horizontal A. 5 and the lower slot 11
The movement of the falling lock 4 is prevented by the three points of the inner edge of the pin and the contact point h to the pin 6, and the locked state is maintained.
