Abstract:
1. An industrial robot comprising: a mounting base; a turning base rotatable relative to the mounting base about a rotation axis; and a stopper mechanically limiting an operating angle of the turning base, the stopper comprising: a fixed section attached to the mounting base, wherein the cross section of the fixed section perpendicular to the rotation axis of the turning base is substantially sector-shaped; a connecting base attached to the turning base, the connecting base comprising a bottom wall and two side walls substantially perpendicular to the bottom wall, wherein each of the two side walls defines a shaft hole, and two shaft holes of the two sidewalls are aligned; and a swing lever pivotally connected to the connecting base and capable of swinging between a first position and a second position, wherein the swing lever defines a through hole extending radially, and the stopper further comprises a retaining shaft received in the through hole and the two shaft holes of the two side walls, the bottom wall defines a limit hole for receiving the swing lever, and the turning base is maintained in the first position and the second position, respectively, by the stopper when the swing lever contacts the fixed section, thereby limiting the operating angle of the turning base.
