- the forceps 35 has both the front cylindrical portion 36 and the rear flange portion 38 made of hard plastic, but the cylindrical portion 36 is made of a metal such as brass. You may comprise.
- the cylindrical portion 36 is not easily elastically deformed, the force for clamping the tensile body 52 with the caulking ring 45 is strengthened, and the cylindrical portion 36 is difficult to be plastically deformed. Power is maintained for a long time.
