Description

Handle stick of cleaning tool {HANDLE STICK OF CLEANING TOOL}

The present invention relates to a handle stick of a cleaning tool, and more particularly, to a handle stick of a cleaning tool that can be connected to a dust mop, a duster or a tape cleaner, etc. and whose length can be adjusted.

In general, a cleaning tool such as a mop, duster, or tape cleaner has a handle stick that is held by a user's hand. A hair or tape cleaner is constructed.

Republic of Korea Patent Registration No. 10-2182640 (2020.11.24.) (hereinafter referred to as 'prior art 1') discloses a 'hand stick wet mop cleaner'.

The prior art 1 discloses the 'mop rod', which is the handle stick, and has a structure in which the mop rod is connected to the 'main bracket', which is a part constituting the head of the wet mop, through a 'hinge block'.

However, since the prior art 1 is sold in a form in which the main bracket is coupled to the mop rod through the hinge block, the main bracket cannot be separated from the mop rod, and storage is cumbersome.

Republic of Korea Utility Model Registration No. 20-0180762 (May 15, 2000) (hereinafter referred to as 'prior art 2') discloses a 'mop with a handle coupled in a rotational manner'.

The prior art 2 discloses a 'handle bar', which is the handle stick, and a 'fastener' for fixing the mop, which is a part constituting the head of the mop, and the handle bar fixed thereto to be concave-convex by press processing. It has a structure in which the fastener is coupled by forming a fastening groove portion and coupling the handle bar in a fit-fitting manner, and then pressing the fastener with a 'fixer' from the outside of the fastener.

However, since the handle bar is rotatably coupled to the fastener, there is a problem in that it takes a long time to couple and separate the handle bar from the fastener.
