Abstract

In order to operate the spindle (11), the vehicle jack has an operating head at its upper end incorporating a universal joint consisting of two forks (31, 32) connected by a crosspiece (33). One of the forks is rigidly connected to the spindle while the other can be angularly adjusted and has an e.g. hexagonal sided nut (34) with which a hand crank can be engaged. The radius of the circumferential circle described by the end of the angularly adjustable fork (32) is at least equal to the distance (d) between the cross-piece's axis (o) passing through the two arms of this fork and each of the ends (311, 322) of the arms of the other fork (31). In this way the angle of adjustment of the fork (32) is limited to an angle below 90 deg.
