In a preferred embodiment of the present invention, the fixing base is further provided with a protrusion, the hinge support and the elastic structure are arranged along the length direction of the wiper blade, and the hinge support is located between the protrusion and the elastic structure; the two inner surfaces of the scraping arm connector are contacted with the two side surfaces of the protruding portion, so that the scraping arm connector is limited to be separated from the fixing seat.
In a preferred embodiment of the present invention, the windward side of the wiper arm connector is a curved surface, and the leeward side of the wiper arm connector is formed by a straight surface and a curved surface, and the curved surface is in smooth transition connection with the straight surface and the curved surface.
In a preferred embodiment of the present invention, the inclined surface is an outer convex inclined surface.
By adopting the technical scheme, the side wall stop block is added on the fixed seat, so that the elastic structure is considered to be opened during assembly, and the elastic structure is released after assembly. The elastic structure plays a double-locking role on the transverse release of the scraping arm, and ensures that terminal customers cannot release accidents absolutely.

Detailed Description
The invention is further described below with reference to the drawings and detailed description.
Referring to fig. 1 to 4, the improved wiper suitable for high-speed running of a vehicle is shown to include a wiper arm 10, a fixing base 20, and a wiper blade 30, the wiper blade 30 being fixed to the fixing base 20.
The fixing base 20 has a hinge seat 21 and a protrusion 22, and an elastic structure 23, the elastic part 23 and the protrusion 22 are separately disposed on two sides of the hinge seat 21 parallel to the length direction of the wiper blade 30, and two sides 22a, 22b of the protrusion 22a are inclined surfaces. The inside of the hinge support 21 is provided with a shaft hole 21a, and the axis of the shaft hole 21a is perpendicular to the length direction of the wiper blade.
The scraping arm 10 is provided with a scraping arm connector 11, and the outer surface of the scraping arm connector 11 is provided with a windward side 11a and a leeward side 11b; the windward side 11a is a slant surface, and the slant surface is an outer convex slant surface.
A shaft 12 is anchored to the windward side 11a of the wiper arm attachment 11, the shaft 12 extending in the direction of the leeward side 11b of the wiper arm attachment.
The leeward side 11b of the wiper arm connector 11 is provided with a sidewall stopper 11ba and a notch 11baa, and the notch 11baa corresponds to the hinge support 21 and the elastic structure 23 for retracting the hinge support 21 and the elastic structure 23.
During assembly, the wiper arm connector 11 is obliquely upwards at an angle to the length direction of the wiper blade 30, the notch 11ba on the leeward side 11b is aligned with the hinge support 21 and the elastic structure 23, the bottom of the windward side 11a of the wiper arm connector 11 and the bottom of the leeward side 11b are simultaneously higher than the protruding part 22, then the edge 11baaa of the side wall baffle 11ba is used for pushing the wiper arm connector 11, the elastic structure 23 is squeezed out, then the wiper arm connector 11 is transversely moved or the fixing seat 20 and the wiper blade 30 are transversely moved, the shaft 12 on the wiper arm connector is inserted into the shaft hole 21a of the hinge support 21, and after the shaft 12 is inserted into place, the elastic structure 23 is restored to be deformed to the initial position, the edge 11baaa of the side wall baffle 11ba is blocked, and the side wall baffle 11ba is prevented from retreating.
