The insertion portion includes a first inclined edge having a diagonal surface inclined downward in a direction from a first end of the body to the hollow portion, a second inclined edge having a diagonal surface inclined upward from a second end of the body to the first inclined edge, the second end being positioned opposite the first end, and a third inclined edge having a diagonal surface inclined downward in a direction from an end of the first inclined edge to the second inclined edge
