When replacing the semicircular plate, the locking mechanism and the unlocking mechanism need to be replaced together, which increases the processing cost of the semicircular plate and reduces the utilization rate of replaceable materials.

[0023] The mounting mechanism 3 comprises a socket 301 and a heat-insulating base 302. The socket 301 is provided on the outer wall of the heat-insulating shell 2.

A rotating shaft 304 is rotatably connected to the inner wall of the groove. A stopper 305 is fixedly mounted on the outer wall of the rotating shaft 304. The stopper 305 blocks the outer side of the heat-insulating shell 2. A metal elastic plate 306 is fixedly mounted on the outer wall of the stopper 305. A semicircular block 307 is fixedly mounted on the outer wall of the movable end of the metal elastic plate 306. A semicircular block 307 is provided on the inner wall of the groove on the insert block 303. The circular card slot 308 and the semicircular card slot 308 are provided with two groups, upper and lower. The insert block 303 is passed through the insertion hole 301, and then the stopper 305 is rotated to block the outside of the heat-insulating shell 2, so as to limit and fix the heat-insulating shell 2. The semicircular card slot 307 can be inserted into the semicircular card slot 308 by using the elastically deformable metal elastic plate 306, and can also leave the semicircular card slot 308 when pushed by an external force, so as to ensure that the stopper 305 can be rotated, so that when the insert block 303 is passed through the insertion hole 301, the stopper 305 is level with the insert block 303. The upper and lower groups of semicircular card slots 308 are provided to fix the stopper 305 in two states: horizontally and vertically. The heat-insulating base 302 is provided to connect the insert block 303 with the combustion furnace 1 and provide a heat-insulating function;

[0024] The heat insulating base 302 includes a mounting base 3021 and a heat insulating body 3022. The mounting base 3021 is fixedly mounted on the outer wall of the combustion furnace 1. The heat insulating body 3022 is fixedly mounted on the outer wall of the mounting base 3021. The heat insulating body 3022 is fixedly connected to the plug block 303. The mounting base 3021 is provided for welding the heat insulating base 302 to the outer wall of the combustion furnace 1. The heat insulating body 3022 is provided for ensuring that the heat insulating base 302 has a heat insulating function.

[0025] A heat dissipation ring 4 is fixedly sleeved on the outer side of the top of the combustion furnace 1, and heat dissipation holes 5 are provided on the top and bottom of the heat dissipation ring 4.

The pull plate 9 makes it easier to rotate the stopper 305, and the curved surface design makes it easier for the user to pinch the pull plate 9 with fingers.

[0029] Working principle: When in use, the pull plate 9 is pulled to cause the block 305 to be stressed, and then the metal elastic plate 306 is stressed. After the elastic deformation condition of the metal elastic plate 306 is reached, the metal elastic plate 306 is deformed to drive the semicircular block 307 to move, so that the semicircular block 307 is disengaged from the semicircular slot 308, and the block 305 is rotated to make the block 305 perpendicular to the plug block 303, and the heat insulating shell 2 is moved horizontally, so that the block 305 and the plug block 303 pass through the socket 301, and then the two heat insulating shells 2 are assembled together, and the block 305 is rotated so that the block 305 blocks the outside of the heat insulating shell 2, and the heat insulating shell 2 is limited and fixed. At this time, the metal elastic plate 306 pushes the semicircular block 307 into the semicircular slot 308, fixes the block 305, and prevents the block 305 from continuing to rotate.

[0030] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
