A three-scraping-piece flexible wall round hole internal-supported wiper connecting rod blade hydraulic type windscreen wiper comprises a wiper motor and a wiper driving mechanism and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe and transfer torque, and a connecting rod rocker arm drive mechanism is arranged on the driving blade swing oil cylinder. The three-scraping-piece flexible wall round hole internal-supported wiper connecting rod blade hydraulic type windscreen wiper that the wiper driving mechanism of the windscreen wiper performs hydraulic drive through a flexible pipe, is large in transfer torque, small in size and quick in response, is small in structural limitation during installation due to the fact that the hydraulic drive by means of the flexible pipe is adopted, is completely of a closed structure, is low in noise during working, is especially suitable for a complicated external environment structure and remote transmission and is not influenced by the outside, the defect that the wiper motor is burned down due to an external obstacle is avoided, interior noise is effectively reduced, the interior comfort of a vehicle in running is improved, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and the efficiency of a three-scraping-piece structure is triple of the scraping efficiency of a common single scraping piece.
