The invention discloses a pump truck supporting leg oil cylinder. The pump truck supporting leg oil cylinder is characterized in that a cylinder bottom is welded to one end of a cylinder barrel, an oil return through hole is formed in the side wall of the cylinder barrel, one end of the oil return through hole is communicated with an oil return hole formed in the cylinder bottom, the other end of the oil return through hole is communicated with an inner cavity of one end of the cylinder barrel, the inner wall of the other end of the cylinder barrel is provided with a guide sleeve, a piston rod penetrates through the guide sleeve to be inserted into the cylinder barrel, and a piston is arranged at the end, extending into the cylinder barrel, of the piston rod through a locking nut. In this way, an oil return pipe does not need to be arranged on the outer side of the cylinder barrel, the size of the cylinder body is reduced, the weight of the cylinder block is reduced, during operation, the oil cylinder cannot be damaged by an operation environment, and the service life of the oil cylinder is guaranteed.
