The limit rod 3 passes through the main limit holes 11 and is used to limit the PCB board. After adopting the above scheme, during use, the PCB board to be baked is pushed into the support groove 21, and then the limit rod 3 is passed through the main limit holes 11. The plurality of limit rods 3 are used to limit the PCB board from both ends respectively to ensure the stability of the PCB board. Then, the bracket loaded with the PCB board is placed in the baking equipment for baking and processing of the PCB board; when necessary, according to the actual width of the PCB board, the countersunk head screws can be loosened first, and then the side plate 2 is moved. At this time, the side plate 2 drives the countersunk head screws to move along the waist-shaped counterbore 13 to adjust the distance between the two side plates 2, which is applicable to PCB boards of different widths and has a wide range of applications.

[0038] Optionally, as shown by Figure 1 and Figure 2 In this embodiment, three main crossbeams 1 in the same group are equally spaced in the horizontal direction.
