Abstract
A ratchet structure includes a body. The body is provided with a plurality of equally spaced ratchet teeth extending along the axial direction, and an annular groove is formed on the body to divide the body into a head portion and a body portion. The ratchet teeth are located on the body portion, and a predetermined groove is provided between the ratchet teeth and the annular groove. With the predetermined groove, when the milling cutter mills out the groove in the body portion and enters the predetermined groove, the waste chips connected to the annular groove bottom surface of the annular groove will be surely cut off, thereby solving the problem that it is difficult for the ratchet wheel to get rid of the waste chips.
