Windscreen wiper device with function range convenient to adjustTechnical Field
The invention relates to a windscreen wiper device with a conveniently adjusted action range, and belongs to the technical field of automobile accessory structures.
Background
A wiper, also called a wiper, a wiper blade, or a windshield wiper, is a device for wiping off raindrops and dust attached to a windshield of a vehicle, so as to improve visibility of a driver and increase driving safety. Because of legal requirements, almost all motor vehicles come with wipers. The rear windows of vehicles such as hatchbacks and recreational vehicles are also equipped with wipers. In addition to automobiles, other transportation means are provided with wipers such as trains, trams, and the like. Some engineering machines, such as cranes, etc., are also equipped with wipers. At present, most glass wipers are of wiper structures, and can scrape off large-area glass surface water. However, since a certain distance is left between the two wipers, a part of the area above the middle parts of the two wipers cannot be touched by the glass wipers.
