Drawstring restringing apparatus
摘要:
A drawstring restringing apparatus includes a front end, a rear end, and a mid-portion located between the front end and the rear end. The front end and a portion of the mid-portion adjacent to the front end are hollow. A leading portion of the front end is tapered from a top portion of the front end to a bottom portion of the front end. A portion of the front end, which is behind the leading portion, includes a closed top. A portion of the mid-portion adjacent to the front end includes an open top, and the open top defines a mid-portion gap which has a mid-portion-gap width. The open top of the mid-portion extends through the rear end, whereby the rear end also includes an open top. The closed top of the front end includes a slit. The slit has a slit-gap width. The slit-gap width is less than the mid-portion-gap width.
