Easy assembly vehicle jack

摘要

The lift jack (1) has a strut (2) and a lever arm (4) mounted for pivoting on the strut when actuated by a screw rod (6), turning in a nut (8), articulated in cut outs (25) in the strut. The nut is held on the strut by engagement of a retainer (89) fixed to the nut. This is done using at least one curvilinear aperture (27) formed in the strut and centred on the axis of articulation of the nut on the strut. Each cut out in the strut can be formed as a groove with its base formed by a semi-circular face.
