- The present invention relates generally to a cleaning tool, and more particularly to a cleaning tool having a cleaning head that could be detached and replaced easily.
- A conventional cleaning tools have multiple types and designs for different purposes. The conventional cleaning tool includes a long rod body for a user to hold easily. Taking a scraper for removing dirt, snow, or water as an example, an end of the long rod body is connected to a cleaning head, wherein the cleaning head could be a broom, brush, snow shovel, or a scraper. Since the long rod body and the cleaning head of the conventional cleaning tool is fixed, more space is needed for storing the cleaning tools for different purposes. Therefore, the cleaning tool with the fixed cleaning head is not convenient for storing.
- In order to solve the aforementioned defect, there is a cleaning tool on the market, wherein a long rod body is detachably connected to a cleaning head. For example, according to “Brushware operating lever with telescopic locating function” of China utility model patent publication number CN201270923Y, an end of a connecting rod is disposed with a protruding lump, and a rotating rod is disposed with a fixing hole. When the connecting rod is inserted into the rotating rod, the protruding lump is engaged with the fixing hole, thereby connecting the connecting rod and the rotating rod.
- According to the disclosure of the aforementioned patent, when the connecting rod is about to be disengaged from the rotating rod, the protruding lump should be pressed downwardly first to allow the protruding lump leaving from the fixing hole. After that, the connecting rod is withdrawn from the rotating rod, so that the connecting rod and the rotating rod are departed. However, the protruding lump is adapted to lock the components and to be pressed by the user. When the user presses the protruding lump by a finger and withdraws the connecting rod from the rotating rod, the finger is easily pinched between an edge of the fixing hole of the rotating rod and the protruding lump of the connecting rod. On the other hand, when the connecting rod is about to be assembled with the rotating rod, the protruding lump needs to be pressed for allowing the connecting rod to be inserted into the rotating rod. During the assembly process, the finger could probably be pinched and injured. Besides, the protruding lump and the connecting rod is integrally formed as a monolithic unit, so that the protruding lump is connected to the connecting rod via a small rib, thereby allowing the protruding lump could be pressed. After repeatedly used for a long period of time, the small rib is easily broken due to the stress. In such situation, the structure losses the function of connecting.
- In view of the above, the primary objective of the present invention is to provide a cleaning tool, wherein a cleaning assembly of the cleaning tool could be easily and safely detached from and mounted to the holding rod, so that the cleaning assembly could be replaced easily.
