Disclosed is an intelligent front clamping type jack enabling construction to be achieved conveniently. A kicker cylinder is fastened to the front end of a tensioning cylinder, the outer diameter of the kicker cylinder is smaller than that of the tensioning cylinder, and the center line of the kicker cylinder is coaxial with that of the tensioning cylinder; the front end of a hollow sleeve is of a stepped structure, and the stepped wall serves as the pushing driving surface of the kicker cylinder; a sealing plug is fastened to the rear end of the hollow sleeve, and the side wall of the sealing plug serves as the pushing driving surface of the tensioning cylinder. The jack has the advantages that a piston is omitted, structure is extremely simple, the working supporting surface of the front end is small, the jack is suitable for various construction occasions, construction is convenient, steel strands are saved, and the jack is especially suitable for prestresstension construction sites where space is limited.
