[0017] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. For the purpose of clarity, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not necessary. In addition, for the purpose of simplifying the illustration, some conventional structures and components will be depicted in a simple schematic manner in the illustration.

[0018] like Figure 1-4 As shown, the utility model is a special tool for milling the middle groove of the middle plate of a small end face, including a workbench 1, a fixed base 2, and a turntable 3. The upper end of the workbench 1 is fixedly connected to the fixed base 2, and the upper end of the fixed base 2 is rotatably connected to the turntable 3. The four corners of the turntable 3 are provided with positioning pin holes 302. The turntable 3 is rotated to a horizontal position or a vertical position. After the positioning pin 4 is installed in the positioning pin hole 302, the edge of the positioning pin 4 clamps the edge of the middle plate to be processed, thereby realizing the limitation of the horizontal position or vertical position of the middle plate to be processed.
