Windshield wiper with even pressing force

摘要

A windshield wiper (1) with an even pressing force is connected to a driving arm (2) and includes a primary wiper frame (10), two auxiliary wiper frames (20), connecting frames (30), and a wiper blade (40). The primary wiper frame (10) includes a fixing base (11) connected to the driving arm (2). The auxiliary wiper frames (20) are disposed on both ends of the primary wiper frame (10). Each auxiliary wiper frame (20) includes an elastic piece (21) and a pivotal base (22) fixed to the elastic piece (21) and pivotally connected to the primary wiper frame (10). The connecting frames (30) are evenly provided on each auxiliary wiper frame (20). Each connecting frame (30) includes a pressing piece (31) and buckling brackets (32). The wiper blade (40) is disposed through the buckling brackets (32) to be connected below the pressing piece (31).
