The invention belongs to the technical field of ultra-light two-seat helicopters and discloses a plate type rotor head of a closed ultra-light two-seat helicopter. The plate type rotor head is used for solving the problem that the cost is high because the conventional rotor head is high in manufacturing precision. The plate type rotor head disclosed by the invention comprises a rotor head hub, a main rotor seat, a main rotor positioning seat, a main rotor rocker arm and a teeterboard, wherein the teeterboard is connected to the front and rear ends of the rotor head hub and can vertically rotate around the rotor head hub; shaft holes are formed in the left and right ends of the teeterboard; the shaft holes are provided with a main rotor positioning shaft; one end of the main rotor positioning shaft is fixedly connected into the shaft holes; the other end of the main rotor positioning shaft is sequentially arranged in the main rotor seat and the main rotor positioning seat in a sleeving manner; the upper and lower sides of the main rotor seat and the main rotor positioning seat are respectively connected with a main rotor upper clamping plate and a main rotor lower clamping plate; a main rotor is clamped between the main rotor upper clamping plate and the main rotor lower clamping plate; and the upper side of the main rotor upper clamping plate is connected with the main rotor rocker arm used for adjusting the main rotor to rotate around the main rotor positioning shaft.
