Vehicle lifting jack has cog segment of pivoted carrier arm cooperating with cog section of control slider displaced parallel to support column

摘要

The lifting jack has a support base mounted on the ground (4), provided by a support column (1) and a foot (2), with a carrier arm (5) attached to the support column so that it pivots about a fixed horizontal axis under control of an operating spindle (7). The pivoted end of the carrier arm has a toothed cog segment (13) cooperating with a cog section of a 2-part control slider (10), which is displaced parallel to the longitudinal axis of the support column.
