Quick install nut

A quick install nut comprising:

• an engagement assembly provided with a main body and at least one movable member;
• the main body having an entrance end, an exit end, and an insertion slot defined in the main body for allowing a threaded fastener to insert through;
• the movable member mounted adjacent to the entrance end of the main body and moved axially along the main body to be close to or away from the insertion slot;
• a tightening ring mounted and limited in the entrance end of the main body and maintained at an open position normally;
• While being abutted against and pressed on, the tightening ring moved from the open position to a closed position axially along the main body and positioned in the closed position in an elastically recoverable manner;
• the movable member is further driven to move so that the threaded fastener is engaged in the engagement assembly to form a threaded structure;
• and
• at least one reinforcing fixing member inserted through the main body from the exit end to the entrance end and threaded with the tightening ring;
• the reinforcing fixing member able to be turned and operated to protrude from the tightening ring and generate a pressing and tightening effect when the tightening ring is in the closed position.
