SCREW JACK ASSEMBLY FOR PAVING MACHINE

A screw jack assembly includes a first body defining a longitudinal axis and a screw drive disposed within the first body. The screw jack assembly also includes a second body movable relative to the first body and coupled to the screw drive, and a first gear coupled to the screw drive. The screw jack assembly further includes a handle assembly having a tube member coupled to the first body. The handle assembly also includes a second gear coupled to the first gear. The handle assembly further includes a handle member coupled to the second gear and adapted to rotate about a rotational axis substantially perpendicular to the longitudinal axis. The handle member is adapted to selectively rotate between an operating position and a stowed position about the longitudinal axis based, at least in part, on rotation of the tube member relative to the first body along the longitudinal axis. 一种螺旋千斤顶组件，包括限定纵向轴线的第一本体和设置在第一本体内的螺旋驱动器。螺旋千斤顶组件还包括相对于第一本体可移动并且联接到螺旋驱动器上的第二本体，以及联接到螺旋驱动器上的第一齿轮。螺旋千斤顶组件进一步包括手柄组件，手柄组件具有联接到第一本体上的管构件。手柄组
