[0037] The steel sheet 5 is in the shape of an elongated strip and is inserted into the first decorative strip 2 , the mounting seat 1 , the wiper seat 4 and the second decorative strip 3 .

[0038] A plurality of connection seats 6 are detachably arranged on the steel sheet 5 at intervals.

[0039] The rubber strip 7 is in the shape of an elongated strip, and is detachably disposed on the bottom surfaces of the plurality of connecting seats 6 .

[0040] In this embodiment, the connecting seat 6 includes a connecting head 61 that is detachably arranged on the steel sheet 5 and an elastic strip 62 that is connected to the connecting head 61 and is in the shape of a long strip, wherein the connecting head 61 is arranged at the top end of the center of the elastic strip 62, and the bottom surface of the elastic strip 62 is provided with a clamping groove 625 along its length direction for accommodating the top end of the rubber strip 7.

[0041] Preferably, the elastic strip 62 is in the shape of a long rectangular strip, wherein a first baffle 621 and a second baffle 622 are respectively extended downward on both sides of the elastic strip 62, and a first clamping plate 623 and a second clamping plate 624 are respectively extended downward on both sides of one end of the elastic strip 62, the bottom end of the first clamping plate 623 is provided with a first extension plate 6231 extending horizontally toward the second clamping plate 624, and the bottom end of the second clamping plate 624 is provided with a second extension plate 6241 extending horizontally toward the first clamping plate 623, and the bottom surface of the elastic strip 62, the first clamping plate 623, the second clamping plate 624, the first extension plate 6231 and the second extension plate 6241 form a clamping groove 625. Furthermore, a third clamping plate 626 and a fourth clamping plate 627 are respectively extended downward from both sides of the other end of the elastic strip 62.

It should be understood that the retaining groove 625 is formed at both ends of the elastic strip 62. The first baffle 621 and the second baffle 622 are also used to clamp the rubber strip 7 below the elastic strip 62. The first clamping plate 623 and the third clamping plate 626 are connected to the first baffle 621, and the second baffle 622 and the fourth clamping plate 627 are connected to the second baffle 622.

[0042] Furthermore, a first clamping groove 71 and a second clamping groove 72 are respectively provided on both sides of the top of the rubber strip 7. The first extension plate 6231 and the third extension plate 6261 are respectively positioned within the first clamping groove 71, and the second extension plate 6241 and the fourth extension plate 6271 are respectively positioned within the second clamping groove 72. It should be understood that the rubber strip 7 is used to wipe dust and dirty water off the automobile glass, and the multiple elastic strips 62 can better confine the rubber strip 7 to the surface of the automobile glass to prevent it from tilting. The first extension plate 6231, the second extension plate 6241, the third extension plate 6261, and the fourth extension plate 6271 are respectively positioned within the first clamping groove 71 and the second clamping groove 72. When the rubber strip 7 wipes the automobile glass surface, it can be confined within the connecting base 6 to prevent the rubber strip 7 from detaching from the wiper blade.

[0043] Preferably, the top of the rubber strip 7 received in the retaining groove 625 is further provided with a third clamping groove 73 located above the first clamping groove 71 and a fourth clamping groove 74 located above the second clamping groove 72, respectively, on both sides.

[0046] In this embodiment, the steel sheet 5 is provided with a clamping hole 51 , the top end of the connecting rod 612 passes through the clamping hole 51 , and the clamping rod 613 is rotatably set at the top end of the steel sheet 5 so that the entire connecting seat 6 is clamped on the steel sheet 5 through the clamping rod 613 .

[0047] Preferably, the length of the clamping rod 613 is smaller than the length of the clamping hole 51, and the length of the clamping rod 613 is larger than the width of the clamping hole 51. In other words, the connecting seat 6 can be disassembled and assembled on the steel sheet 5 by rotating the connecting rod 612 of the connecting head 61. For example, when the long end of the clamping rod 613 is rotated to align with the long end of the clamping hole 51, the clamping rod 613 can be installed from the clamping hole 51. After installation, the connecting rod 612 is rotated again so that the long end of the clamping rod 613 is no longer parallel to the long end of the clamping hole 51, and the installation process of the connecting seat 6 is completed. If you want to disassemble the connecting seat 6 from the steel sheet 5, you only need to rotate the long end of the clamping rod 613 to align with the long end of the clamping hole 51, and then push the clamping rod 613 out of the clamping hole 51 to complete the disassembly of the connecting seat 6 from the steel sheet 5. When the locking rod 613 is locked outside the locking hole 51 , the connecting seat 6 will not be separated from the steel sheet 5 because the length of the locking rod 613 is greater than the width of the locking hole 51 .

[0048] Furthermore, a first extension arm 21 and a second extension arm 22 are provided on both sides of the first decorative strip 2 to extend downward, the first extension arm 21 is provided with a first clamping arm groove 211 for accommodating and clamping one side of the steel sheet 5, the second extension arm 22 is provided with a second clamping arm groove 221 for accommodating and clamping the other side of the steel sheet 5, and a third extension arm 31 and a fourth extension arm 32 are provided on both sides of the second decorative strip 3 to extend downward, the third extension arm 31 is provided with a third clamping arm groove 311 for accommodating and clamping one side of the steel sheet 5, and the fourth extension arm 32 is provided with a fourth clamping arm groove 321 for accommodating and clamping the other side of the steel sheet 5.

[0049] Furthermore, a fifth extension arm 41 and a sixth extension arm 42 are extended downward on both sides of the bottom surface of the wiper base 4, wherein the bottom end of the fifth extension arm 41 is bent and forms a fifth clamping arm groove 411 on one side of the bottom surface of the wiper base 4 for accommodating and clamping the steel sheet 5, and the bottom end of the sixth extension arm 42 is bent and forms a sixth clamping arm groove 421 on the other side of the bottom surface of the wiper base 4 for accommodating and clamping the steel sheet 5.

[0050] It can be understood that the first decorative strip 2, the second decorative strip 3, and the wiper base 4 are each connected to the steel sheet 5 through their own clamping arm grooves, so that the first decorative strip 2, the second decorative strip 3, and the wiper base 4 are all tightly attached to the rubber strip 7, so that the wiper has a certain hardness, so that the outer surface of the wiper will not deform during the process of scraping the automobile glass. In addition, if dust or dirt is hidden between the rubber strip 7 and the steel sheet 5, the first decorative strip 2, the second decorative strip 3, and the wiper base 4, the steel sheet 5 can be removed from the clamping arm groove, and then the connecting base 6 can be removed from the retaining hole 51 of the steel sheet 5. The rubber strip 7 can then be removed from the retaining groove 625. In this way, the first decorative strip 2, the second decorative strip 3, the wiper base 4, and the rubber strip 7 can be cleaned one by one, and any damaged components can be replaced at this time.

[0051] Furthermore, a first supporting side plate 43 and a second supporting side plate 44 extend upward from the top of the wiper base 4.
