The invention relates to an externally folded crane mechanism which is fixed in a truck. One end of the first folding column is hinged to the stand column, the other end of the first folding column is hinged to one end of the second folding column, the first folding column rotates around a hinge point through a first driving mechanism, and the second folding column rotates around a hinge point through a second driving mechanism; and the clamping jaw assembly is hinged to the other end of the second folding column, the second driving mechanism drives the second folding column to rotate around a hinge point until the clamping jaw assembly makes contact with the surface of the truck for supporting, the first driving mechanism drives the first folding column to rotate around the hinge point, and therefore the clamping jaw assembly is driven to move from the folded state to the working state.
