USPTO Abstract
A jack having a detachable rear-end handle comprises a wheeled jack and a hand-held ring. Two sidewalls of the jack are each provided with a pair of blocking pieces respectively mounted on an upper location and a lower location about a screw nut of a rear shaft. The hand-held ring can be coupled to screw nuts of a rear shaft. The blocking pieces further restrict the rotation of the hand-held ring. The connection of the hand-held ring at the rear end of the jack not only facilitates carrying the jack but also controlling the movements of the jack to a proper lift point.
