Because the windshield is easy to intercept and is adhered with a large amount of sand and dust in the driving process of the automobile, when the number of the rubber strip assemblies 4 is two, the problem that the sweeping part 42 on the rubber strip assembly 4 is seriously abraded due to the fact that the rubber strip assemblies 4 are adhered with the sand and dust can be effectively solved; secondly, because the adhesive tape components 4 are easy to age after being subjected to direct sunlight for a long time, the situation that the single adhesive tape components 4 are inconvenient to scrape rain after being aged is easy to occur, and when the adhesive tape components 4 adopt the two adhesive tape components 4 of the scheme and are arranged, the sticky sand of the adhesive tape components 4 and the abrasion caused by aging are only generated at the outer sides of the two adhesive tape components 4 which are far away from each other, the side edge of the sweeping part 42 between the two adjacent adhesive tape components 4 can still normally work, and the service life of the wiper component is further effectively prolonged; secondly, when two adhesive tape subassemblies 4 are carrying out windscreen wiper work, first adhesive tape subassembly 4 is scraped once roughly, and second adhesive tape subassembly 4 is then scraped once finely on the basis of first adhesive tape subassembly 4 is scraped roughly, and consequently the windscreen wiper effect that reaches is more excellent than single adhesive tape subassembly 4. On the basis, the advantages of the windscreen wiper with the framework (uniform stress distribution and capability of being tightly attached to the windshield of the automobile for wiping) are utilized, so that the wiping effect can be further improved.

The skeleton assembly 3 comprises a main skeleton 31 and a three-level skeleton 33 with a cross section in an inferior arc shape; the number of the three-level frameworks 33 is two, one end of the main framework 31 is connected to the middle part of one three-level framework 33, and the other end of the main framework is connected to the middle part of the other three-level framework 33; both ends of the three-level framework 33 are connected with the rubber strip component 4 through the first universal fastener 5. The skeleton assembly 3 includes a second-stage skeleton 32, one end of the second-stage skeleton 32 is connected with the main skeleton 31, and the other end is connected with a third-stage skeleton 33. The number of the three-stage frameworks 33 is at least two and is uniformly distributed along the axial direction of the rubber strip assembly 4. The framework component 3 further comprises a connecting framework 34 for connecting the main framework 31 and the three-level framework 33, one end of the connecting framework 34 is rotatably connected to the main framework 31, and the other end of the connecting framework is rotatably connected to the middle part of the three-level framework 33; both ends of the three-stage framework 33 are slidably connected to both sides of the adhesive tape component 4 through the first universal fasteners 5.

The adhesive tape assembly 4 comprises a clamping part 41 for clamping and mounting and a sweeping part 42 for scraping off the glass attached; the clamping portion 41 is provided with first grooves 6 along two axial side faces of the clamping portion. In the present embodiment, the clamping portion 41 and the sweeping portion 42 are formed integrally as a product commonly used in the art.

The first universal fastener 5 comprises a second buckling part 52 with a C-shaped cross section, and the second buckling part 52 is inserted into and clamped and fixed in the first groove 6. The side of second buckle portion 52 extends and is provided with the crooked first installation department 8 towards tertiary skeleton 33, and tertiary skeleton 33's side is seted up with 8 assorted second breachs 10 of first installation department, and first installation department 8 matches the joint in second breach 10. The two axial sides of the adhesive tape component 4 are respectively provided with a first notch 9 matched with the first universal fastener 5, and the first universal fastener 5 is arranged in the first notch 9 in a buckling mode. The first buckling part and the second buckling part 52 are C-shaped in cross section, and two are independent sheet metal parts. The second locking portion 52 and the first mounting portion 8 are formed by a sheet metal bending technique, and the first locking portion, the third locking portion and the fourth locking portion are formed by a sheet metal bending technique, but not limited thereto.

Firstly, the first mounting part 8 is mounted in the second gap 10 in a matching way, so that the first buckling part and the second buckling part 52 are mounted in a matching way to form a first universal fastener 5 with an integrated structure; then, sequentially penetrating the adhesive tape assembly 4 into second buckling parts 52 of a plurality of first general assemblies along the axial direction of the first groove 6, so that the adhesive tape assembly 4 is installed on the second buckling parts 52; then, one ends of a plurality of first universal fasteners 5 are arranged on the three-stage framework 33 in a buckling mode, and the other ends of the first universal fasteners are correspondingly clamped in the first notches 9; after the installation, the first universal fasteners 5 located at the two ends of the framework component 3 are respectively fixed in the two first notches 9 of the adhesive tape component 4 corresponding to the buckles, and the other universal fasteners located between the two first universal fasteners 5 can slide along the axial direction of the first groove 6.
