[0027] The shaped grinding wheel is placed in the fixing groove 12 in the fixing plate 8, and the grinding wheel is fixed by the fixing structure so as to heat and bake the grinding wheel;

[0028] The fixing structure includes a connecting rod 22 fixedly connected to the upper pressure plate 14, the inner wall of each connecting rod 22 is slidably connected with an adjusting rod 23, and each adjusting rod 23 penetrates the inner wall of the connecting rod 22 and extends to the outer side of the connecting rod 22, the bottom end of each adjusting rod 23 is fixedly connected with a fixed pressing block 24, the position of the fixed pressing block 24 corresponds to the fixing groove 12, the inner wall of the connecting rod 22 and the adjusting rod 23 are fixedly connected by a connecting spring 25, the side walls of the upper pressure plate 14 and the fixing plate 8 are fixedly connected with a connecting block 15, the connecting block 15 connected to the upper pressure plate 14 is fixedly connected with a connecting screw 16 penetrating the connecting block 15, and the connecting block 15 connected to the fixing plate 8 is rotatably connected with a threaded block 17 matching the connecting screw 16;

[0029] The threaded block 17 is rotated. Since the connecting screw 16 cannot be rotated, the connecting screw 16 will move with the rotation of the threaded block 17 under the action of the thread, so that the connecting screw 16 and the upper pressure plate 14 move toward the direction of the fixed plate 8, driving the connecting rod 22, the adjusting rod 23 and the fixed pressure block 24 to move accordingly, so that the fixed pressure block 24 is pressed on the grinding wheel, and the connecting spring 25 allows the adjusting rod 23 and the connecting rod 22 to be telescopic, so that grinding wheels of different thicknesses can be fixed, and the grinding wheel is also prevented from being damaged during the fixing process;
