[0002] Windshield wipers are standard components on cars, primarily used to clear dust, debris, and rainwater from the windshield to ensure clear visibility for the driver. Currently, the most common type of wiper is the frameless wiper, which mainly consists of a wiper blade and a wiper strip. The wiper blade is connected to the car's drive unit and is detachably connected to the wiper strip. This is because wiper strips are consumables, so the connection between the wiper blade and the wiper strip must be easy to disassemble. However, the detachable connection methods commonly found in the market have some drawbacks.

[0003] For common button-type wiper structures, the wiper blade can be directly installed on the wiper mount by clicking the button. However, different models of wiper blades have different structures and do not have a locking slot on the top for engaging with the button. Therefore, a special connecting piece needs to be designed to improve the compatibility of the wiper and enable it to support wiper blades of various structures. Summary of the Invention
