In this way, the flat surface of the square housing 31 allows the tool magazine 100 to be easily connected to the CNC machine tool (not shown) using the tool magazine 100 through the square housing 31. Moreover, because the shape of the square housing 31 and the shape of the tool holder 1 match each other, the volume and cost of the tool magazine 100 can be effectively controlled.
[0026] The tool holder 1 is roughly in the shape of a rectangular parallelepiped, and includes an upper plate 11, a lower plate 13 and a spacer supported between the upper plate 11 and the lower plate 13 arranged at intervals. The upper plate 11 and the lower plate 13 are respectively provided with a plurality of accommodating holes (not shown) corresponding to each other. The tool 2 is set on the tool holder 1 through the containing holes of the upper plate 11 and the lower plate 12 and a part of the tool holder 1 is exposed.
[0027] In practical applications, the shape of the first protective cover 3 should not be limited by this. For example, the first protective cover 3 may be configured as an overall fan-shaped cylindrical shape or an overall square shape that accommodates the tool holder 1.
[0028] The second shield 4 includes a second sector-shaped cylindrical shell 41. The first sector-shaped cylindrical shell 32 and the second sector-shaped cylindrical shell 41 are rotationally connected in a coaxial manner. For details, please refer to figure 1 , Figure 4 with Figure 5. The shaft of the first sector-shaped cylindrical shell 32 is provided with a bearing 321, and the shaft of the second sector-shaped cylindrical shell 41 is provided with a rotating shaft 42.
