[Prior art]

 With the presence of cars, human behavior has become more and more convenient. An automobile is made up of many parts, for example, windshield glass is one of them, and windshield glass is exposed to many factors such as wind, rain, sunshine, etc. Generates waste such as bird droppings. At this time, you have to wipe it off with a wiper. Most of the well-known wiper blades only have blade rubber attached, and when cleaning dirt attached to the windshield glass of automobiles, the dirt attached to the windshield contains granular particles that fall in the air. There are limbs and bird droppings of insects hit by headwinds while driving, and simply scraping with a blade rubber can cause dirt to be applied to the glass surface. A severe phenomenon occurred, and the hardness of some of the dust was extremely high. During the process of removing the wiper, the pressed glass surface and the blade rubber were extremely easily damaged. For this purpose, a kind of wiper blade is provided, in which a single wiper blade is provided with a single layer of blade rubber, and a single row of strips stretched longitudinally on both the front and rear sides thereof. A brush is provided to clean the windshield glass of the car, first removing bird droppings, dead insects or dust, removing any other dirt, and also using the outermost blade rubber to recover the wiper during recovery. To assist the lack of water repellency. However, such a wiper sheet has a blade formed integrally with a brush, lacks elastic adaptability, and can provide only a slightly flat water repellent effect, and if used on curved glass, the effect is not clear. . However, all windshield glasses of automobiles have a curved surface, which makes it impossible to achieve the ideal result as expected in use, which in turn affects the water repellency of the wiper, and also reduces the blade rubber and brush. The wiper blade integrally formed cannot be separated and replaced at the time of local damage, and if the whole is replaced, unnecessary waste is formed. Therefore, an improvement is required.

In view of the above-mentioned drawbacks of such known wiper blades, the present invention has been made to improve the drawbacks.

[Problems to be solved by the invention]

 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a kind of wiper front assist device, which is a detachable front assist device which is attached to a wiper blade of an automobile, and has a resilient side on one side of the wiper blade of the automobile. A fixed part that penetrates the part fixes the divided arch-shaped arm and one seat body provided with a brush, and the blade rubber is pivotally connected to the seat body through this divided-type arched arm. Thus, the blade rubber has a good elasticity adapting ability to adhere to the glass curved surface during use, and the blade rubber is made independent and can be separated and replaced independently, so that unnecessary waste can be reduced.
