A double-scraper flexible shaft type windscreen wiper with flexible walls and a wiper connecting rod comprises a windscreen wiper motor, a wiper driving mechanism and wipers and is characterized in that a wiper driving shaft is divided into a driven wiper driving shaft and a driving wiper driving shaft, a driven gear and a driving gear are arranged on the driven wiper driving shaft and the driving wiper driving shaft, the driven gear and the driving gear are connected through a flexible shaft, and torque is transmitted between the driven gear and the driving gear through the flexible shaft. A closed connecting rod and rocker arm driving mechanism is arranged on the driving gear. As the wiper driving mechanism of the windscreen wiper is of a closed structure, noise is low when the windscreen wiper works, the windscreen wiper is particularly suitable for the complex external environmental structure and long-distance transmission, the defect that the windscreen wiper motor is burnt due to external obstacles is overcome, the noise in a vehicle is effectively lowered, and the comfort in the vehicle is improved when the vehicle operates; windscreen wiper rubber strips are supported by the flexible walls and therefore can fit windscreen better, and the scraping efficiency of the double-scraper structure is two times that of a general single scraper.
