[0002] With the improvement of people's living standards and the progress of technology, people have higher requirements for cleaning tools, and no longer stay in the stage of low-end products. There are certain requirements for both the quality and function of products.

[0003] Although the existing glass squeegees can clean glass, they can only turn in one direction and cannot be positioned. Moreover, the button of the plug-in part for extending the glass squeegee has no protection function, resulting in difficulty in resetting the button after long-term use. Therefore, a rotatable positioning single-sided squeegee is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the embodiments of the utility model is to provide a rotatable positioning single-sided squeegee, aiming to solve the following problems: the existing glass squeegees can only turn in one direction and the button of the plug-in part for extending the glass squeegee has no protection function.

[0005] The embodiments of the utility model are implemented as follows. A rotatable positioning single-sided squeegee includes: a connecting sleeve and a stop block. The connecting sleeve is provided with a bayonet, a sliding opening and a slot opening. The slot opening is arranged at the front end of the connecting sleeve, and the stop block is fixedly arranged in the connecting sleeve; an extension mechanism which can be inserted into the connecting sleeve and clamped at the bayonet. The extension mechanism can be installed and disassembled through the connecting sleeve and is used to extend the overall length of the single-sided squeegee; a reversing mechanism which is rotatably installed in the slot opening formed in the connecting sleeve. A squeegee for cleaning glass is installed on the reversing mechanism; a clamping mechanism which is slidably installed on the connecting sleeve and passes through the sliding opening. One end of the clamping mechanism is fixedly connected with the stop block, and the other end can be clamped into the reversing mechanism to limit the rotation of the reversing mechanism on the connecting sleeve.

[0006] Preferably, the extension mechanism includes: an extension rod which is cooperatively arranged with the connecting sleeve. The extension rod can be inserted into the connecting sleeve. An elastic button is installed on the extension rod, and the elastic button can be clamped into the bayonet to fix the extension rod and the connecting sleeve; a spring piece which is installed in the extension rod and abuts against the elastic button, and is used to assist the elastic button to reset after being clamped into the bayonet.

[0007] Preferably, the reversing mechanism includes: a clamping block which is rotatably installed in the slot opening formed in the connecting sleeve. A clamping groove is arranged on the outer side of the clamping block, and the clamping mechanism can be clamped into the clamping groove to limit the rotation of the clamping block; an upper pressing plate which is fixedly connected with the clamping block. The upper pressing plate is fixedly connected with a lower pressing plate through bolts, and the squeegee is pressed between the upper pressing plate and the lower pressing plate.

[0008] Preferably, the clamping mechanism includes: a slider slidably mounted within the connecting sleeve, a reset spring fixedly provided on one side of the slider, and the end of the reset spring away from the slider is fixedly connected to a stop block; a rotation-limiting block fixedly connected to the other side of the slider, and the reset spring is used to push the rotation-limiting block into the clamping groove formed in the clamping block; a pull-twist slidably disposed at the sliding opening formed in the connecting sleeve and fixedly connected to the slider by a bolt for pulling the rotation-limiting block out of the clamping groove formed in the clamping block.

[0009] The single-sided scraping device with rotational positioning provided by the present utility model can not only clean glass, but also adopts a spring ejection mechanism design. When it is necessary to rotate to different directions, only by pulling and releasing the button switch on the surface, the spring can achieve positioning by retracting and extending. Further, a spring piece is provided within the extension rod to ensure that the elastic button can still rebound and reset after long-term use. The operation is simple and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
