[0025] The bottom plate 102 is placed horizontally on the base 101; several side plates 103 are arranged perpendicular to the bottom plate 102 and are all connected to the base 101; the top plate 104 is connected to the side plates 103 and is parallel to and spaced apart from the bottom plate 102. The top plate 104 cooperates with the side plates 103 and the bottom plate 102 to form a accommodating cavity 105; the support assembly includes a first support bar 106 and a second support bar 107 located in the accommodating cavity 105 and respectively connected to the side plates 103. The first support bar 106 and the second support bar 107 are both made of a bending-resistant polymer material. The first support bar 106 passes vertically through the bottom plate 102 and is connected to the base 101. The second support bar 107 is parallel to the top plate 104 and is connected at the angle between the side plate 103 and the top plate 104.
