摘要

The mechanism comprises two identical articulated parallelogram mechanisms (1) located at the two ends of the tool holder table (4) and supporting it. Each of the parallelogram mechanisms is in the form of two balance arms (1a). A bar (1b) has a central hole for a pin (3) linked to the table (4). The pin passes through a gear (3a) driven by a chain or a motor unit (7).
