Abstract

A movable stage includes a playing surface, a movable mechanism, a control circuit, and a switch. The movable mechanism includes a longitudinal movable mechanism and a widthwise movable mechanism. The widthwise movable mechanism comprises cam mechanism and a movable mechanism. The protruding distance between an original state portable plate and the cam touch contact is 0. When the cam and the portable plate are in the original state that the protruding distance is 0, the distance between the longitudinal wheel and the playing surface is larger than the distance between the widthwise movable and the playing surface. When the cam and the portable plate are in the state of maximum protruding distance, the distance between the longitudinal wheel and the playing surface is smaller than the distance between the widthwise movable and the playing surface. The utility model adopts the longitudinal movable mechanism and widthwise movable mechanism which can realize two-direction move via a motor driving a cam mechanism with no need of labor to move on site, convenient and laborsaving. The stage can be adjusted to move through the switch at the same time with the live performance. The performance form is varied and the scene effect is better.
