[0036] Working principle: First, when the sealing cover plate 2 needs to be released, the limit block 402 is manually pulled, and the limit block 402 moves and separates from the rotating rod 306, and then the rotating rod 306 is pulled upward, and the upward movement of the rotating rod 306 drives the fixing plate 305 to move upward, and the movement of the fixing plate 305 drives the connecting rod 304 to move, and the upward movement of the connecting rod 304 stretches the first spring 303, and the fixing protrusion at the bottom of the fixing plate 305 moves and separates from the square groove above the sealing cover plate 2;
[0037] Secondly, when the fixing protrusion of the fixing plate 305 is completely separated from the sealing cover plate 2, the rotating rod 306 is rotated, and the rotation of the rotating rod 306 will drive the fixing plate 305 to rotate, and the fixing plate 305 rotates and the position of the sealing cover plate 2 no longer overlaps, and the rotating rod 306 is released, and the first spring 303 will restore its deformation and pull the connecting rod 304 to move downward, and the movement of the connecting rod 304 drives the fixing plate 305 to move, and the fixing plate 305 moves to fit above the shell of the convection frame main body 1, and then the sealing cover plate 2 is pulled to complete the disassembly;
[0038] Finally, when the sealing cover plate 2 needs to be installed, the sealing cover plate 2 is placed above the convection frame body 1, and the limit block 402 is pulled again to separate it from the rotating rod 306. The movement of the limit block 402 will cause the second spring 403 to deform, and then the rotating rod 306 is pulled, and the movement of the rotating rod 306 will drive the fixed plate 305 to move. The movement of the fixed plate 305 causes the first spring 303 to deform, and then the rotating rod 306 is rotated, and the movement of the rotating rod 306 will drive the fixed plate 305 to move. The fixed plate 305 rotates and moves to above the square groove of the sealing cover plate 2, and the rotating rod 306 is released. The first spring 303 will restore the deformation so that the fixed protrusion at the bottom of the fixed plate 305 is inserted into the square groove above the sealing cover plate 2, and then the limit block 402 is released, and the second spring 403 will restore the deformation to push the limit block 402 to fit the rotating rod 306, completing the installation of the sealing cover plate 2.
