US Patent 10364567 Connector for framing material

A connector for framing material comprises: a limiting member, a connecting member and a first screw. The hexagon portion of the first screw is received between the first stopping plate and the second stopping plate of the limiting member. The through hole of the connecting member is passed by the first screw to form a pre-lock assembly of the limiting member and the connecting member. The first stopping plate and the second stopping plate parallel to the accepting slot direction to place the limiting member in the U-shaped frame, and then the connecting member is rotated and to make a cross with the U-shaped frame, such that the first screw drives the limiting member to rotate to perpendicular to the U-shaped frame.
