Then manually rotate the turntable 13. The rotation of the turntable 13 drives the rotating rod 11 to rotate, thereby driving the second gear 803 to rotate. The rotation of the second gear 803 drives the first gear 801 to rotate. The rotation of the first gear 801 drives the screw rod 5 to rotate, thereby driving the sliding sleeve 4 to move upward.
