The width at end is of same size with the second end of extension 214, the second end different from first end of the second transition part 216 and company
The first end of socket part 218 connects, and the width of the second end of the second transition part 216 is of same size with the first end of interconnecting piece 218,
Second end of the width of second transition part 216 from the width gradual change of the first end of the second transition part 216 to the second transition part 216
Width.For example, when extension 214 and interconnecting piece 218 are embodied as cylinder, the second transition part 216 can be implemented as justifying
Platform shape.Similar with the effect in First Transition portion 212, the effect of the second transition part 216 is to realize extension 214 and interconnecting piece
Width adaptation between 218 so that the two width in connection is gradual change rather than mutation, so as to avoid extension
214 occur discontinuous point when connecting with interconnecting piece 218, it is ensured that milling cutter 20 will not stress concentration in the process of target 10
And it is broken.
