A positioning and fitting groove 4 is arranged at the top edge of the support base 2, and limiting arc blocks 5 are evenly arranged at the inner side edge end of the positioning and fitting groove 4. A connecting and fitting block 6 is connected corresponding to the positioning and fitting groove 4 at the bottom end of the main box body 1. During the process of the connecting and fitting block 6 being inserted into the positioning and fitting groove 4, the side edge of the connecting and fitting block 6 is in close contact with the side edge of the limiting arc block 5, making the connection between the connecting and fitting block 6 and the positioning and fitting groove 4 tighter, ensuring higher tightness between the main box body 1 and the support base 2 after the initial connection, and the main box body 1 is fitted and connected with the positioning and fitting groove 4 through the connecting and fitting block 6 at its bottom end;

[0027] A bolt seat 7 is arranged at the outer side edge end of the support base 2, and a fastening seat 8 is arranged corresponding to the bolt seat 7 at the inner side edge end of the main box body 1. The positions and numbers of the bolt seat 7 and the fastening seat 8 correspond to each other, and the bolt seat 7 and the fastening seat 8 are fixedly connected by a locking bolt, which can further limit and fix the side edges of the main box body 1 and the support base 2, so that the main box body 1 and the support base 2 have higher stability after the alignment connection, preventing looseness and instability during the working process. Bottom support strips 9 are evenly arranged at the inner side edge end of the support base 2, inner strengthening ribs 10 are arranged at the inner side edge end of the main box body 1, a reinforced leaky hole bottom frame 11 is arranged at the bottom end of the support base 2, and reinforced bottom sheets 12 are evenly arranged at the bottom end of the reinforced leaky hole bottom frame 11. Limiting clamping seats 13 are symmetrically arranged at the four side edges of the bottom of the reinforced leaky hole bottom frame 11. The limiting clamping seats 13 are L-shaped. The support net at the bottom of the support base 2 is fitted and clamped inside the limiting clamping seats 13 in a pushing and clamping manner, which is convenient to install the support net at the bottom of the support base 2 in a pushing and clamping manner, so as to facilitate the protection of the bottom of the support base 2.
