At this time, a suspended object such as a hanger is locked by screwing a nut to the suspension bolt.

[0003]

Conventionally, the work of screwing the nut to the suspension bolt has been performed manually. Therefore, the nut can be easily attached when the locking position is at a short distance from the bolt end, but a considerable working time is required when the nut is attached at a distance from the bolt end. For example, when connecting a two-stage hanger to a suspension bolt, the hanger on the lower stage of the suspension bolt is installed at a position closer to the lower end of the suspension bolt, so it is easier to screw the nut, but the hanger on the upper stage of the suspension bolt is Since it is installed at a position distant from the lower end of the hanging bolt, it takes a lot of time and labor to manually fix the nut screw (see FIG. 2).

Therefore, this invention was developed in order to shorten the work time for screwing a nut to a long screw bolt such as a suspension bolt.
