The moving grooves 18 are evenly distributed on the outer wall of the driven teeth 5, and the inner wall of the transmission groove 18 is in contact with and slidably connected to the outer wall of the transmission curved tooth 8. The outer diameter of the power tooth 6 is smaller than the inner diameter of the power cylinder body 14, and the inner wall of the transmission curved tooth 8 is in contact with the outer wall of the power tooth 6. A second connecting flange 4 is connected to one side of the power cylinder body 14, and an electric push rod 1 is fixedly installed on one side of the second connecting flange 4. An oil seal plate 13 is slidably connected to the outer wall of the power shaft rod 12, and the outer wall of the oil seal plate 13 is connected to the inner wall of the power cylinder body 14. The end of the power cylinder body 14 away from the electric push rod 1 is connected to the power cylinder cover 11, and one end of the power shaft rod 12 passes through the power cylinder cover 11 and extends out of the power cylinder body 14.
