Embodiment

Name preferred embodiment, and become apparent from intactly illustrating the utility model with reference to accompanying drawing.

As shown in figure 1, a kind of inner diameter lathe tool 10, it includes handle of a knife 11 and the cutter head 12 being connected with handle of a knife 11, cutter head 12 be bulb, and bulb is provided with a blade 13, and the first end of blade 13 is located at the side of end of the bulb away from handle of a knife 11, blade 13 The second end be located at bulb close to the position of handle of a knife 11.Blade 13 is made up of some sections of connected circular arcs.

In the present embodiment, two adjacent circular arcs are tangent, and the radius of some sections of circular arcs is identical.

In another embodiment, two adjacent circular arcs can be tangent, and the radius of some sections of circular arcs can be different.The circle of different radii Arc can be by realizing to the grinding of bulb surface in various degree.In another embodiment, the radius of some sections of circular arcs can be from first end Become larger to the second end.

Handle of a knife 11 is pole, and the centre of sphere of bulb is located on the axis of pole, and a neck 14, neck are provided between pole and bulb The diameter in portion 14 is less than the diameter of bulb.The diameter with diameter greater than bulb of pole.A cone can be passed through between pole and neck 14 Face 15 is connected, and the angle of the conical surface 15 and the outer peripheral face of pole is 30 °.In other embodiment, the conical surface 15 and the outer peripheral face of pole Angle can be configured as other angles.
