The invention discloses a windscreen wiper for an automobile. The windscreen wiper comprises first hinges fixed to the two sides of the front and rear ends of the bottom of a connecting plate correspondingly. The ends, away from the connecting plate, of the two first hinges at the front end and the rear end are fixedly connected with the two ends of the top of a clamping plate. Limiting screw grooves are formed in the four corners of the side walls of the two clamping plates. The windscreen wiper has the following beneficial effects: an adjusting knob is rotated to drive a threaded rod to movein a threaded groove, and the threaded rod can abut against the side wall of the rear end of the connecting plate, so when an auxiliary windshield wiper frame rotates through a second hinge, the windshield wiper frame rotates only clockwise; when the auxiliary windshield wiper frame rotates in the counterclockwise direction, after the auxiliary windshield wiper frame rotates to a certain angle, the auxiliary windshield wiper frame cannot be continuously rotated due to limiting of the threaded rod; and when a main rubber wiper blade rotates passively, the auxiliary rubber wiper blade at the bottom of the auxiliary windshield wiper frame is driven to rotate together, and the auxiliary windshield wiper frame and the auxiliary rubber wiper blade are prevented from being broken through movement when touching the corners of the windshield through rotation of the auxiliary windshield wiper frame, so that the windshield wiper can move flexibly.

    本发明公开了一种汽车用雨刮器,包括连接板底部前后两端的两侧均固定有一号铰链,且前后两端的两个所述一号铰链远离连接板的一端分别与夹板的顶部两端固定连接,两个所述夹板的侧壁四角均开凿有限位螺槽,本发明的有益效果:通过旋转调节旋钮,带动螺纹杆在螺纹槽内移动,使螺纹杆能抵住连接板的后端侧壁,使副雨刷架在通过二号铰链的转动时,只能以顺时针的方向进行转动,而以逆时针方向转动时,转动到一定的角度后,因螺纹杆的限位从而无法继续转动,当主橡胶刮片被动旋转时,带动副雨刷架底部的副橡胶刮片一并旋转,副雨刷架和副橡胶刮片通过副雨刷架的转动,从而防止触碰到挡风玻璃边角时,通过活动避免折断的问题,可以灵活移动。
