AI Technical Summary
The output shaft assembly of existing wipers is prone to loosening, and the installation angle of the wiper arm and output linkage requires adjustment by a professional.
The output shaft is fixed by interference fitting with a toothed structure, the installation angle is limited by a keyway, and screwless installation is achieved by ball joint and circumferential limiting groove, thus fixing the initial position.
This achieves stable installation of the wiper arm, avoids bolt loosening, simplifies the production and assembly process, and reduces reliance on professional personnel.
