A front end of the bottom frame is rotationally connected with a front end of the side frame. A top support rod is fixed at a rear end of the side frame. Left and right ends of the top support rod are respectively connected with an upper-section tail support rod rotating around an axis thereof. A tail end of the upper-section tail support rod is connected with a folding joint. The other end of the folding joint is connected with a lower-section tail support rod. A rear end of the bottom frame is connected with a tail rack rotating around a shaft parallel to the axis of the top support rod.
