[0023] Example 2: Figure 3 and Figure 4A through hole 110 is provided on the inner wall of the protrusion 150, and the through hole 110 is U-shaped. The top of the through hole 110 is semicircular, and the bottom corners on the left and right sides of the through hole 110 are set as rounded corners 120.
