摘要
The tube (1) has an extension piece (3) welded to its inside near its top so that it forms a shoulder (1a). A tube (2) can be pushed down over the extension piece to the shoulder to interlock the two tubes. The bottom of tube (2) carries a half tube (8) hinged at one end (7) and notched near the other end (9) to form a hook. The top of the extension piece carries a pin bolt (4) perpendicular to the tube axis and protruding outside the tube so that the hook (10) can lock onto it. The bottom of the tube (2) is notched on both sides (6) so that the pin bolt can pass through the notch during tube interlock.
