Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of a tool for cleaning burrs of an annular groove according to the present invention; fig. 2 is a schematic view of a partial cross-sectional structure of the annular groove burr cleaning tool provided by the present invention; fig. 3 is a schematic structural view of the handle provided by the present invention.

The utility model discloses an annular groove burr clearance instrument, annular groove burr clearance instrument includes: a blade 1 and a handle 2.

One end of the handle 2 is provided with a groove 21, part of the blade 1 is arranged in the groove 21, part of the blade protrudes out of the handle 2, and the part of the blade 1 protruding out of the handle 2 comprises a triangular knife edge 11.

In the annular groove burr cleaning tool in the embodiment, the handle 2 is held by hands, the triangular knife edge 11 is stretched into and clamped in the annular groove, and burrs of the annular groove can be completely scraped by rotating the product with the annular groove at a low speed, so that the annular groove burr cleaning tool is simple and labor-saving to operate and high in production efficiency. And the arrangement of the triangular knife edge 11 can adapt to the widths of the notches of various annular grooves.
