A scraping plate of the longitudinal moving windscreen wiper is of an integrated structure composed of the two wiper blades. The connecting ends of the two wiper blades are in attraction connection through a pair of magnets with opposite polarities, and the magnets are wrapped by the connecting ends of the two wiper blades. The wiper blades are in hinged connection with the wiper gear arms. The wiper blades can rotate around the wiper gear arms. The wiper gear arms are driven by a motor to do up-down reciprocating motion. The wiper gear arms are sleeved with the wiper rack arms. The two gears are mounted at the lower portions of the wiper gear arms. The inner walls of the wiper rack arms are provided with rack grooves. The two gears are meshed with the rack grooves to drive the wiper gear arms to move in the wiper rack arms in the longitudinal direction. The large wiper arms are mounted outside the wiper rack arms. The wiper rack arms can move in the large wiper arms in the longitudinal direction. The bottom ends of the large wiper arms are connected with the large wiper arm mandrels. The longitudinal moving windscreen wiper is more thorough in water wiping and large in operating area, so a driver can drive more safely on rainy and snowy days.
