[0003] The manual chamfering tool and the mechanical chamfering tool currently used in the market are mostly designed as single function, and can only perform single upper chamfering or lower chamfering. In addition, these tools usually need to be replaced between different processing tasks to adapt to different chamfering requirements, thereby increasing working time and operation complexity. Meanwhile, when the tools for upper chamfering and lower chamfering are switched, the tolerance requirements and process requirements generated in subsequent processing are greatly different, and the defective product rate is high. The manual chamfering tool is simple to operate and has low cost, but is low in efficiency and high in skill requirement for operators. The manual chamfering tool is usually not suitable for large-scale or precision processing. The mechanical chamfering tool can be installed on a machine tool such as a milling machine or a lathe, and can automatically perform chamfering processing. However, most of the mechanical chamfering tools can only perform upper chamfering or lower chamfering, and the conventional tools may not be made of optimal materials, so that they are quickly worn under high load or high wear conditions and need to be frequently replaced, thereby increasing maintenance cost. Therefore, the utility value is insufficient and needs to be improved. UTILITY MODEL CONTENT
