The insertion groove is formed on the top center of the body part. The screw groove is formed on the bottom center of the body part. The top flange is formed on the top edge of the body part. The middle flange is formed in the middle edge of the body part and has a longer radius than the top flange. The bottom flange is formed on the bottom edge of the body part and has a longer radius than the middle flange. The cut groove is formed in a circular band shape to surround the screw groove. The inner diameter of the cut groove is more than the diameter of the body part, and the outer diameter thereof is less than the diameter of the bottom flange. |
