The present invention discloses a convertible worktable convertible between a storage configuration and an assembled use configuration. The worktable comprises a tabletop has a top surface and a bottom surface, a top frame fixed to the bottom surface of the tabletop and a bottom frame being spaced apart and coaxial to the top frame. The bottom frame having a first side and a second side opposite to the first side. The worktable further comprises a plurality of legs fastened to the top frame and extends beyond and in contact with the bottom frame. A fastener assembly detachably fastens the plurality of legs to the top frame and the bottom frame and defines an assembled use configuration. The fastener assembly allows detachment of the plurality of legs from the top and bottom frame, fastens the plurality of legs and the bottom frame alongside the top frame, and defines a storage configuration.

A bracket (20) includes: a pedestal (21, 22) that is mountable on a support frame (2) of a work stand (1) for supporting a saw (60); and first and second engaging parts (38A, 38B) arranged on the pedestal to sandwich the support frame in a horizontal direction and engage with first and second engagement parts (8A, 8B) on opposite sides of the support frame. The second engaging part includes first and second levers (41, 42). The pedestal is movable along the longitudinal direction of the support frame by manipulating only the first lever to disengage it from the second engagement part (8B) and is removable from the support frame by simultaneously manipulating both the first and second levers in the same direction to disengage them from the second engagement part. The first and second levers both move in the same opposite direction to engage the second engagement part.

An aircraft structure manufacturing device is provided with: a jig supporting a component of an aircraft structure; a plurality of raising/lowering stands; and a control unit for controlling positions of support parts of the raising/lowering stands. The control unit includes: an input unit inputting position information for a movement destination of a reference point provided to the component; a storage unit storing, in advance, master data, which is the relationship for position information of the support parts of respective raising/lowering stands corresponding to the position information for the movement destination; a unit position information acquisition unit acquiring position information for the support part of each of the raising/lowering stands, based on the master data and the position information for the movement destination; and the movement command unit for simultaneously moving the support parts of a plurality of raising/lowering stands.
