Because the radius of the second sector gear 10 is larger than that of the first sector gear 7, when the second sector gear and the first sector gear rotate relatively, the rotation angular velocity of the gear at the top of the paddle board 1 with the smaller radius is obviously larger than that of the fan-shaped transmission arm 9, so that the angular velocity of the paddle board 1 connected with the gear for cutting the viscous liquid 3 is increased, and the energy consumption capacity of the viscous damper is further enhanced.
