The invention relates to a tensioning jack for a deformed steel bar. The defects that an existing deformed steel bar is tensioned and screwed directly by workers in the manner of wrenching of a nut by hand, the screwing work is troublesome, and dangerousness is high are overcome. A supporting component is connected to the front end of the jack and comprises a supporting sleeve and a nut screwing component arranged in the supporting sleeve. The nut screwing component comprises a nut sleeve matched with the nut, and a ratchet mechanism driving the nut sleeve to rotate. The ratchet mechanism is connected with a drive handle, and the drive handle extends out of the supporting component. The supporting component is used for separating the jack from an anchor plate, and a position large enough for installing of the nut screwing component is reserved. The nut sleeve of the nut screwing component is used for being matched with the nut on the deformed steel bar. The ratchet mechanism can drive the nut sleeve to rotate. The nut sleeve rotates to screw the nut. The ratchet mechanism is connected with the drive handle. The drive handle extends out of the supporting component. A worker can carry out operation outside and does not need to stretch in the hand to directly wrench the nut, and the operation safety is ensured.
