The invention provides a foldable support leg mechanism. The foldable support leg mechanism comprises an upper support leg, a lower support leg and a middle support leg, wherein the upper support leg and the lower support leg are respectively hinged to the upper and lower ends of the middle support leg through support leg connecting plates; the lower end of the lower support leg is in cup joint with a cushion plate support leg; a shaft hole and a chute corresponding to each other are formed in the lower support leg and the cushion plate support leg; an adjustable shaft sleeve is arranged in the shaft hole; a spring is arranged between the lower support leg and the cushion plate support leg; one end of the spring is fixed on the lower support leg, and the other end is fixed on the chute through a bolt; and a support leg lower cushion plate is arranged at the bottom of the cushion plate support leg. The foldable support leg mechanism can effectively support the ground to bear the load of the front half part of a semitrailer when a tractor is decoupled from the semitrailer. The mechanism uses the spring for controlling gears through the fit of several pin shafts to realize adjustable support of the semitrailer mechanism. The foldable support leg mechanism can preferably solve the problem of supporting the load of the front half part of the semitrailer, reduces the manual operation and the cost, and has excellent economic and social benefits.
