摘要

The jig has aluminum beams (11, 12) arranged between battens (21, 22), and arranged in support with the battens to define parallelism and to define spacing between the beams. A regulating unit (30) is placed between the beams to regulate the parallelism and the spacing. The regulating unit has a screw or nut type blocking device (33) that blocks aluminum male and female telescopic elements (31, 32) of the regulating position in a desired position.
