A plurality of aluminum blades 3 are fixedly connected to the outer wall of the outer lining 2. A locking and fixing assembly is provided between the lining 1 and the outer lining 2;

[0027] The locking and fixing assembly includes a plurality of slots 401, a plurality of card slots 402, a plurality of blocks 403, a limiting groove 404, and an elastic snap ring 405. A plurality of slots 401 are opened on the side wall of the lining 1. A plurality of card slots 402 are opened on the inner side of the outer lining 2. A plurality of blocks 403 are fixedly installed between the slots 401 and the card slots 402. The limiting groove 404 is opened on the inner side of the lining 1. The elastic snap ring 405 is fixedly installed on the inner side of the limiting groove 404. A plurality of slots 401 correspond to the card slots 402 one by one. One end of the block 403 passes through the slot 401 and is fixedly installed inside the card slot 402. The limiting groove 404 is located between two slots 401. The outer surface of the elastic snap ring 405 abuts against one end surface of the block 403.

[0028] It should be noted that through the split design of the lining 1 and the outer lining 2, aluminum blades 3 are installed on the outer side of the outer lining 2. Then, by providing the slots 401, the card slots 402, and the blocks 403, the lining 1 and the outer lining 2 can be locked by passing the block 403 through the slot 401 and snapping it into the card slot 402.
