[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] The following is combined Figure 1-6 This invention describes a specific embodiment of a cutting tool for right-angled parts with an R0 angle, comprising a tool holder 1, which is used to support a mechanism component, and a special cutting tool assembly is provided on the tool holder 1.

[0019] The special tool assembly includes: bushing 2, drive groove 3, driver 4, drive gear 5, groove 6, gear ring 7, shaft groove 8, rotating shaft 9, tool holder 10, cutting blade 11, bolt 12, and bolt hole 13.

[0020] The bushing 2 is connected to the tool holder 10. The shaft groove 8 and the recess 6 are formed inside the bushing 2. The tool shank 1 is connected to the rotating shaft 9. The rotating shaft 9 is installed in the shaft groove 8. The drive groove 3 is formed inside the tool shank 1. The driver 4 is installed in the drive groove 3. The drive gear 5 is fitted on the output end of the driver 4. The gear ring 7 is installed in the recess 6. The bolt hole 13 is formed on the tool holder 10 and the cutting blade 11. The bolt 12 is used to install the cutting blade 11 on the tool holder 10 through the bolt hole 13.

[0021] It should be noted that during the cutting operation, the cutting blade 11 is fixed to the tool holder 10 by bolts 12 and bolt holes 13. The rounded corners can be cut off by the sharp corner at the bottom. The drive gear 5 is driven by the driver 4 to rotate, which in turn drives the bushing 2 with the gear ring 7 to rotate, thereby changing the cutting blade 11 on the tool holder 10, thus reducing the frequency of tool changing by personnel.

[0022] Preferably, the tool holder 10 and the outer side of the cutting blade 11 are configured as a ramp.

[0023] It should be noted that the sloping cutting blade 11 can make the cutting point of the cutting blade 11 protrude, making the cutting more efficient.

[0024] Preferably, and further, the cutting blades 11 are provided in four.

[0025] It should be noted that the four cutting blades 11 can be interchanged, thereby reducing the frequency of manual blade changes and improving work efficiency.

[0026] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
