The invention provides a pantograph device. A power receiving roller is mounted on a pantograph base through a roll shaft, the lower portion of the pantograph base is fixedly connected with a mounting plate, and the mounting plate is connected with a lifting rack. The lifting rack comprises a first support, a second support, a third support and a fourth support. The first support and the second support are hinged to the mounting plate, the lower end of the first support and the lower end of the second support are hinged to the upper end of the third support and the upper end of the fourth support respectively, and torsion springs are arranged at the hinged position of the first support and the third support and the hinged position of the second support and the fourth support. The lower end of the third support and the lower end of the fourth support are fixedly connected with a left gear shaft and a right gear shaft respectively, and the left gear shaft and the right gear shaft are arranged in a mounting base and are parallel to each other. A left gear and a right gear are arranged on the left gear shaft and the right gear shaft respectively, the left gear is meshed with the right gear, and the mounting plate is provided with a vertical limiting device used for enabling the mounting plate to be kept vertical. The pantograph device is simple in structure, the vibration amplitude of a pantograph head is small, the height can be adjusted flexibly, and the stability is high.
