摘要

The system has two tubular columns comprising clamping plates (1), connecting parts (2) and a set of pipes (4) screwed with centering plates (3) and connection parts (5, 6) by a set of threaded rods (7). A side part is screwed with flat bars at the connecting parts, and the clamping plates are screwed with another side part by another set of threaded rods (8). A recess is provided at the connection parts, and corresponds to thickness of the flat bars that are fitted in the latter set of threaded rods and are screwed with another set of pipes and threaded screw caps by hand.
