A centrifugal force change-based device for preventing a stirring device from stalling relates to the technical field of furniture, and comprises a rotating shaft, a turntable is fixedly connected tothe outer side of the rotating shaft, uniformly distributed electromagnets I are fixedly connected to the inner wall of the turntable, and uniformly distributed springs I are fixedly connected to theouter side of the turntable. According to the centrifugal force change-based device for preventing the stirring device from stalling, a clamping block is matched with a movable resistor for use, whenthe rotating shaft rotates and stalls, the clamping block can move outwards under the action of release force, and is clamped to the limiting block to increase the resistance, if stall is too large, the clamping block can drive the movable resistor at the top to gradually rotate rightwards, the larger the stall is, the more the finally electrically connected resistors are, the lower the circuit voltage is, and the lower the rotating speed is, and when the stall reaches the maximum value, all the movable resistors are electrically connected and finally electrically connected with the power-offblock, so that the whole circuit of the stirring device is disconnected, splashing of a coating is effectively avoided, and the coating is effectively saved.
