Convenient-to-operate auxiliary docking mechanism for building outer frame steel pipe

The invention discloses a convenient-to-operate auxiliary docking mechanism for building outer frame steel pipes. The convenient-to-operate auxiliary docking mechanism is composed of an upper sleeve, a lower sleeve, a supporting shaft, a stabilizing rod and a worm-gear speed reducing mechanism, the upper sleeve is composed of two semicircular arcs with one sides connected in a hinged manner and the other sides connected through a bolt, a rotating shaft is fixed on each semicircular arc, section of the lower sleeve is a splay double sleeve which comprises a fixing sleeve and an opening and closing sleeve, the lower portion of the supporting shaft is inserted in the fixing sleeve of the lower sleeve, a wedge-shaped groove gradually deepening from top to bottom is formed in the supporting shaft matched with a fastening screw, the stabilizing rod sleeves the rotating shaft, is axially fixed by a nut and can rotate to realize connection with the upper sleeve, the lower end of the stabilizing rod is open and is fixed on the lower sleeve through a nut, the worm-gear speed reducing mechanism is fixed at the top of the supporting shaft, a gear shaft and another rotating shaft of the upper sleeve are coaxially connected, and a worm shaft is a manual operating portion. The convenient-to-operate auxiliary docking mechanism has high social and economic benefit.
