The lower box body 1 includes a tray 11 and a lower side wall panel 12 fixedly connected to the four sides of the tray 11. The two ends of the inner wall of the lower box body 1 are fixedly connected with end flange panels 13 protruding from the lower side wall panel 12. Side stabilizing panels 15 are fixedly connected with the protruding lower side wall panel 12 on both sides of the inner wall of the lower box body 1 and are used to abut the side walls of the end flange panel 13 to increase the stability of the end flange panel 13. A lower positioning groove 14 is opened on the end flange panel 13. The upper housing 2 includes a top cover 21 and an upper sidewall 22 fixedly connected to the periphery of the top cover 21. End concave edge plates 23 are fixedly attached to both ends of the inner wall of the upper housing 2.
