Since the rotation shafts of the first and second holding

arms

3231 and 3232 are at the first end, the elastic member 3234 is disposed to avoid the gap between the second end of the first holding arm 3231 and the second end of the second holding arm 3232, which causes the holding to be loose. Of course, other methods may be used, for example, the second end of the first holding arm 3231 is an inclined surface, that is, the thickness from the first end of the first holding arm 3231 to the second end of the first holding arm 3231 increases gradually, but such a structure results in a small contact area between the holding portion and the component.
