At the same time, since the opening 112 of the opening groove 11 faces upward and is located below the processing structure, during the processing of the workpiece 40 to be processed, the processing structure can directly process the surface of the workpiece 40 to be processed, and the frame structure will not interfere with the processing, so there is no need to repeatedly move and adjust the position of the frame structure, and thus the convenience of the processing operation and the processing accuracy can be better ensured. Therefore, through the frame structure provided by this embodiment, the technical problem that the center frame structure in the prior art is prone to interfere with the milling processing operation can be solved.

The stable fixation of the workpiece 40 to be processed is formed through the three supports, which not only ensures that the workpiece 40 to be processed does not shake and affect the processing accuracy during the processing of the workpiece 40 to be processed, but also controls the production cost of the frame structure and reduces the assembly difficulty.
