The utility model belongs to a perpendicular transport means technical field is used in the disintegrating slag clearance in the pile foundation construction, difficultly takes a lot of work for solving present well -bucket, can not topple over the problem of disintegrating slag voluntarily, provides a manual hole digging pile emptys simple and easy well -bucket automatically. The symmetry is respectively welded two with axle center clamping ring I on the handle of the staving upper portion left and right sides, and two outside symmetries are respectively welded two with axle center clamping ring II about the staving middle part, and clamping ring I and clamping ring II locate on the same axle center and inside interlude connecting rod, two outsides symmetry perpendicular to staving respectively welds a pivot about the staving lower part, cup joints circle sleeve in two pivots respectively, and circle sleeve revolutes a free rotation, tip welding was fixed in on the circle sleeve in the handle inserted clamping ring I and clamping ring II. The staving is not borrowed external force and is emptyd away the dregs naturally, has reduced the processes such as putting forward, transport, fall of digging the hole workman, labour saving and time saving, and simple structure, the preparation is simple and convenient, has improved work efficiency, is applied to building site bored pile dress and hangs native stone and hoist balk cargos such as grit with the high -rise buildings fitment.
