Abstract: A spring nut assembly is inserted within the internal cavity of a shank tube until the nut is aligned with opposing side holes in the side walls of the shank tube. The spring maintains the nut in alignment with the opposing side walls. A hitch pin including a threaded portion for engaging the spring nut assembly is inserted through the side holes of the receiver tube and the shank tube until the threaded portion of the hitch pin engages the nut mounted within the shank tube. The hitch pin is then rotated relative to the nut to clamp the shank tube against the receiver tube. A lock or clip can be attached to the end of the hitch pin to prevent accidental or unauthorized removal of the hitch pin from the receiver assembly. A bushing can also be used over the reduced diameter.

Abstract translation: 弹簧螺母组件插入到柄管的内部空腔内，直到螺母与柄管的侧壁中的相对侧孔对准。 弹簧保持螺母与相对的侧壁对准。 包括用于接合弹簧螺母组件的螺纹部分的连接销通过接收器管和柄管的侧孔插入，直到连接销的螺纹部分接合安装在柄管内的螺母。 然后，连接销相对于螺母旋转，以将柄管夹紧在接收器管上。 锁扣或夹子可以连接到挂钩销的端部，以防止意外或未经授权地将接头销从接收器组件拆下。 也可以在减小的直径上使用衬套。
