Abstract: A windshield wiper adapter and windshield wiper assembly are disclosed. The windshield wiper adapter comprises a main body and a flexible buckling device. A front end of the main body has a notch that is downwardly recessed. The notch is used for snapping with a protrusion portion of a windshield wiper arm at an arbitrary angle. One end of the flexible buckling device is connected to a surface of the main body while another end is upwardly extended toward an upper side of the main body. The flexible buckling device is used for buckling a leaning side of a through hole of the windshield wiper arm. After the notch is coupled to the protrusion portion, the windshield wiper arm is rotated about a coupling portion therebetween, such that the flexible buckling device is propped by the leaning side of the through hole to firstly perform a deformation process.

Abstract: A windshield wiper connector and windshield wiper connection assembly. The windshield wiper connector comprises a main body, a lodging device and a flexible fastening device. The lodging device is disposed to a rear of the main body to lodge with a barb portion at random angles. One end of the flexile fastening device is connected below a front of the main body while another end is an extending end upwardly extended toward an upper side of the main body. The flexible fastening device leans against a protruding portion. After the lodging device is hooked with the barb portion, the windshield wiper arm is rotated by taking a hooking portion as an axis so that the extending end propped by the protruding portion performs a deformation toward a direction being distant from the protruding portion. When the protruding portion crosses the extending end, the extending end is restored.
