F=f，M=f·（h-H）；

since H is much greater than H, and therefore (H-H) is positive, the resulting bending moment M is inward, and an increase in F causes F to increase, which will also increase. The heavier the weight, the greater the clamping force of the two clamps 9; the F force acts on the hanging beam 6, and the clamp 9 is also fixed on the hanging beam 6, so that the first active and passive transmission shaft 33, the first secondary passive transmission shaft 34, the second active and passive transmission shaft 51 and the second secondary passive transmission shaft are bearing shafts.
