A processing box is fixedly connected to the center of the top of the bottom plate, and a support rod is fixedly connected to the bottom of the inner wall of the processing box and near the central position of the left side. A round rod is fixedly connected to the center of the top of the support rod, and a rotating rod is rotatably connected to the center of the top of the round rod.
