发明名称 Foldable duster
摘要 A foldable duster can be folded to enable selective use of a single-sided or double-sided pile as well as a change in length of the duster. The duster includes a stationary member whose two ends form a pivotally connecting portion and a fastening portion respectively. The fastening portion is configured for connecting with a handle. The pivotally connecting portion is pivotally connected with a folding member. A dusting sleeve coated with pile threads is mounted around the stationary member and the folding member. The folding member can be swung to a position where the folding member and the stationary member form a straight line, thereby straightening the dusting sleeve and extending the duster to its full length. When the folding member is swung to overlap the stationary member, the dusting sleeve becomes folded, and the duster is shortened. Thus, the foldable duster provides convenience of use.

主权项 1. A foldable duster, comprising: a handle; a stationary member having two ends respectively forming a pivotally connecting portion and a fastening portion for connecting with the handle; a folding member pivotally connected to the pivotally connecting portion; and a dusting sleeve having a sleeve body to be mounted around the stationary member and the folding member, the sleeve body having an outer surface having either a pile layer or a cloth strip layer, the folding member being able to be swung to a position where the folding member and the stationary member are arranged along a straight line such that the dusting sleeve is straightened and the duster is extended at full length in order to clean a large-area surface, the folding member also being able to be swung to a position where the folding member overlaps the stationary member such that the dusting sleeve is folded and the duster is shortened in order to clean a complex surface; wherein the fastening portion has a receiving groove opening toward the handle, the receiving groove having an inner wall formed with two symmetrically arranged end openings in communication with outside, the handle having an end having a connecting portion to be inserted into the receiving groove, the connecting portion being formed with two symmetrically arranged elastic hooks, the hooks being configured to be placed in the end openings respectively and elastically and thus be exposed to the outside.
