The utility model relates to the technical field of baking trays, and discloses a high-strength deformation-resistant baking tray which comprises a fixing groove formed in the outer side wall of a supporting block. The fixing block is fixedly connected to the end, away from the inner side wall of the frame body, of the first spring, extends into the baking tray base and is provided with an inclined plane; one end of the pull rod is fixedly connected to the side wall, close to the first spring, of the fixing block, the other end of the pull rod penetrates and extends out of the frame body, and the first spring sleeves the pull rod. A user selects a proper tray surface according to baking requirements, a supporting block at the bottom of the tray surface is placed in the baking tray base, in the process, after the edge of the supporting block makes contact with an inclined face on a fixing block, the fixing block is pushed towards the frame body, a first spring is compressed, and when the bottom of the supporting block makes contact with the baking tray base, a second spring is compressed; at the moment, the fixing blocks and the fixing grooves are located on the same horizontal line, the first springs push the fixing blocks into the fixing grooves, the fixing blocks limit the supporting blocks, and therefore the bottom of the disc face is fixed.
