The rotation of the first screw rod 3 causes the first motion block 5 to move on the first screw rod, and the rotation of the second screw rod 4 causes the second motion block 6 to move on the second screw rod 4. The first motion block 5 and the second motion block 6 always move in opposite or reverse directions. The movement of the first motion block 5 drives the first slider 8 to slide on the slide rod 11 through the first push rod 7, and the movement of the second motion block 6 drives the second slider 10 to slide on the slide rod 11 through the second push rod 9.
[0023] The first slider 8 is rotatably connected to a first lifting rod 12, and the second slider 10 is rotatably connected to a second lifting rod 13.

The intersection of the first lifting rod 12 and the second lifting rod 13 is rotatably connected. When the first slider 8 and the second slider 10 move in opposite directions, the first lifting rod 12 and the second lifting rod 13 will rise, and when the first slider 8 and the second slider 10 move in reverse, the first lifting rod 12 and the second lifting rod 13 will fall.
