At this time, the fixing post 21 extends into the auxiliary block 12, and the notches 131 and 241... The support plate 13 and the mating plate 23 are tightly connected by mutual cooperation, forming a cavity at the rear of the base and a panel at the front. Then, the rubber gasket 16 is fitted into the groove on the mating post 41 at the bottom of the carrier plate 40, and the mating post 41 is inserted into the support post 15. At this time, the bottom surface of the carrier plate 40 is in contact with the top surface of the support post 15, thus supporting and fixing the carrier plate 40. Then, the baking tray 50 is placed on the carrier plate 40. The shape of the carrier plate 40 is designed to form a gap between the carrier plate 40 and the baking tray 50, which can dissipate heat when the heat source is working. At the same time, the cavity formed under the carrier plate 40 can dissipate heat when the heat source is working, and also prevents the heat source from damaging the work surface. In addition, the overall structure of the base has good sealing performance, which improves the safety of the baking tray.

[0060] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
