Screw grooving mechanism

The utility model discloses a screw grooving mechanism which comprises a machine table, a feeding disc used for feeding screws is arranged on the left side of the machine table, a machining table is arranged on the left side of the upper end face of the machine table, and a screw grooving mechanism used for grooving the two faces of each screw at the same time is arranged on a driving mechanism in a linear sliding mode. The motor drives the rotary disc to rotate, rotation of the rotary disc drives the grooving motor and the grooving cutting wheel to conduct adjustment of different grooving angles, and after the angle of the grooving cutting wheel is adjusted, driving force is generated through cooperation of the driving motor and the driving sliding block; the grooving cutting wheel with the adjusted angle transversely moves at the grooving position of the screw to conduct grooving operation on the screw, then the grooving cutting wheel can conduct grooving on the two faces of the screw at the relative angle,
