A three-scraping-piece flexible wall round hole internal-supported wiper blade hydraulic type windscreen wiper comprises a wiper motor, a wiper driving mechanism and a wiper and is characterized in that two blade swing oil cylinders are communicated through a hydraulic oil pipe and transfer torque, and a forward and reverse rotating gear intermittent drive mechanism is arranged on the driving blade swing oil cylinder. The three-scraping-piece flexible wall round hole internal-supported wiper blade hydraulic type windscreen wiper has the advantages that the wiper driving mechanism of the windscreen wiper performs hydraulic drive through a flexible pipe, is large in transfer torque, is small in structural limitation during installation, is completely of a closed structure, 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, a wiper rubber strip is supported by a flexible wall and can be well fit with a windscreen, and efficiency of a three-scraping-piece structure is triple of the scraping efficiency of a common single scraping piece.
