[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. Fasteners are widely used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, etc. They are the most widely used mechanical basic parts. When processing fasteners, it is usually necessary to use a grinding device to grind the inner ring of the fastener.

[0003] For example, the Chinese utility model patent with the publication number "CN213615814U" discloses a grinding device for processing the inner ring of a fastener. The utility model places the fastener in the positioning groove first, and then uses the knob to rotate the threaded rod so that the threaded rod and the threaded ring are relatively displaced, and then the fastener is squeezed and positioned by the threaded rod. Then, the power of the second motor is turned on, and the second motor is started by the forward and reverse switch. The second motor rotates forward or reversely, driving the threaded protrusion on the support shaft to rotate, and the threaded sleeve moves, cooperating with the limit rod to slide in the strip hole, so that the two grinding strips can approach or move away from each other at the same time, so as to fit with the inner ring of the fastener. Finally, the power of the first motor is turned on, and the first motor drives the two grinding strips to grind the inner ring of the fastener.

[0004] In the above patent, the position of the grinding strip can be adjusted so that the device can be suitable for fasteners of different sizes, but it is difficult to disassemble the grinding structure of the device for replacement. If the surface of the grinding strip is damaged or debris is adhered after long-term use, it is easy to scratch the inner wall surface of the fastener, thus affecting the use of the fastener.
