Multi-dimensional overturning platform for preparing external wall panel for fabricated building

The invention belongs to the field of wallboard preparation, particularly relates to a multi-dimensional overturning platform for preparation of an externally-hung wallboard for a fabricated building, and aims to solve the problems that an existing clamping platform for an externally-hung wall is insufficient in flexibility and can only be adjusted in two dimensions, so that much inconvenience is brought to operators, workers need to operate for a long time when an externally-hung wall board is clamped, and the working efficiency is high. In order to solve the problems that a wall plate body, a placement plate and a bottom plate are included, the wall plate body is placed at the top of the placement plate, and a first fixing plate and a second fixing plate are fixedly connected to the top of the placement plate; one side of the second fixing plate is provided with a clamping assembly used for clamping a wallboard body, the device can be adjusted from three angles, the application range is wide, use is conveni
