As shown in fig. 1 to 4, a first notch 1 matched with the first fastening portion 51 is formed in a side edge of the baffle assembly 3, and the first fastening portion 51 is fastened in the first notch 1 in a matching manner. The side of second buckle portion 52 extends and is provided with the crooked first installation department 8 of first buckle portion 51, and the side of first buckle portion 51 is seted up with 8 assorted second breachs 2 of first installation department, and first installation department 8 matches the joint in second breach 2. The second locking portion 52 and the first mounting portion 8 are formed by using a sheet metal bending technique, and the first locking portion 51, the third locking portion 61 and the fourth locking portion 62 are formed by using a sheet metal bending technique, but not limited thereto.

The guide plate component 3 comprises a guide block 31 and two end buckles 32, and the end buckles 32 are respectively installed at two ends of the guide block 31 in a buckling manner; one end of the first universal fastener 5, which is far away from the adhesive tape component 4, is fixed on the flow guide block 31. The baffle assembly 3 is a component commonly used in the art.

In the embodiment, the double-rubber-strip boneless wiper further comprises a second universal fastener 6 for mounting the rubber strip assembly 4; the side surface of the end buckle 32 close to the rubber strip component 4 is provided with a connecting part 13 which is vertical to the rubber strip component 4 in the axial direction; the second universal fastener 6 comprises a third fastening part 61 and a fourth fastening part 62 with C-shaped cross sections, the third fastening part 61 is clamped and fixed on the connecting part 13, and the fourth fastening part 62 is clamped and fixed on two sides of the adhesive tape assembly 4 along the axial direction of the adhesive tape assembly. Third grooves 11 are symmetrically formed in the adhesive tape assembly 4 along the axial direction of the adhesive tape assembly, and the fourth buckling parts 62 penetrate into and are clamped and fixed in the third grooves 11. In the present embodiment, the first groove 9 and the third groove 11 are on the same extension line along the axial direction of the clamping portion 41, but they do not communicate with each other.

When the fastener is installed, the first installation part 8 is installed in the second notch 2 in a matching mode, so that the first buckling part 51 and the second buckling part 52 are installed in a matching mode, and the first universal fastener 5 of an integrated structure is formed; then, uniformly arranging a plurality of first universal fasteners 5 on the guide plate assembly 3 along the axial direction of the guide plate assembly 3, and correspondingly clamping the first clamping parts 51 in the first notches 1; 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 9, so that the adhesive tape assembly 4 is installed on the second buckling parts 52; next, the third snap-fit portion 61 is mounted on the connecting portion 13 in a matching manner, so that the two ends of the air deflector assembly 3 and the two ends of the adhesive tape assembly 4 are further fixed, so as to improve the integrity of the air deflector assembly 3 and the adhesive tape assembly 4.

The quantity of first general fastener 5 is two at least and along the axial equipartition of guide plate subassembly 3, can be convenient for further improve guide plate subassembly 3 and adhesive tape subassembly 4's wholeness, and then be convenient for improve the effect of windscreen wiper. In the present embodiment, the number of the first universal fasteners 5 is four.

The clamping portion 41 is provided with a second groove 10 extending along the axial direction of the clamping portion, and an integrated elastic sheet 12 is arranged in the second groove 10.
