Claims

[Scope of utility model registration request]

A large-diameter bolt head is provided at both ends of the connecting bolt in line with the bolt neck, and an operating tool such as a screwdriver is attached to one longitudinal end of the rotating connecting body that is rotated around an axis that is approximately perpendicular to the connecting bolt. A large diameter hole larger than the bolt head and a small diameter hole having an opening larger than the bolt neck but smaller than the bolt head are provided in the body of the rotating connection body in the circumferential direction. A cam part is formed in this small diameter hole to draw the bolt head toward the rotating connection body as it moves away from the large diameter hole, and the connecting bolt is inserted through the opening in the end face of both plates to be connected. At the same time, a side hole is formed in which the rotary connection body can be rotatably inserted by communicating with the through hole in a direction substantially perpendicular to the through hole and opening on the plate surface side of the plate material. A plate material formed by locking the bolt head of the inserted connecting bolt to the above-mentioned cam part that moves from the large diameter hole to the small diameter hole and pulls it toward the rotating connection body as the rotation connection body inserted into the side hole is rotated. connection structure.
