When the upper plate 1 moves upwards, the rolling lead screw 5 moves upwards and drives the lead screw nut 13 to rotate forwards, the lead screw nut 13 drives the inner ring of the lead screw one-way bearing 14 to rotate forwards, and the inner ring of the lead screw one-way bearing 14 can drive the outer ring of the lead screw one-way bearing 14 to rotate forwards simultaneously in the rotating direction, so that the rotating shaft cylinder 7 and the transmission gear 6 are driven to rotate forwards continuously. In the upward movement process of the upper plate 1, the upper plate 1 drives the lower plate 4 to rotate reversely through the ball pairs 2 and the ball pair connecting rods 3, but the outer ring of the one-way bearing 12 of the lower plate cannot drive the inner ring of the one-way bearing to rotate in the direction. The transmission gear 6 drives the gear in the speed increasing box 9 to rotate, the output shaft of the speed increasing box 9 transmits the rotation energy to the input shaft of the generator 10 to generate electricity, and the storage battery 11 stores the electric energy.
