A strip opening is formed in the middle of the hollow seat in the front-back direction. Tube connectors are oppositely arranged at the front end and the rear end of the hollow seat in the vertical direction respectively. The first oblique tube penetrates through the strip opening and is hinged to the middle of the strip opening at the center through a hinge shaft. The two second oblique tubes are mounted in the tube connectors at the front end and the rear end of the hollow seat respectively and arranged in parallel and intersect with the first oblique in an X shape. The first oblique tube, the two second oblique tubes and the hollow seat are all located on the same plane.
