The invention relates to a rotating device, in particular to a long-strip screw nut rotating device. The purpose of the invention is to provide the long-strip screw nut rotating device which can rapidly rotate a nut and is high in working efficiency. The long-strip screw nut rotating device comprises a handle, a rotating assembly, a clamping assembly and the like; and the handle is provided with the rotating assembly and the clamping assembly, the clamping assembly is used for clamping the nut, and the rotating assembly is used for driving the nut to rotate. According to the rotating device, the rotating assembly can drive the nut to rotate, the nut is rotated to a long-strip screw, the nut can be screwed out, and manual nut rotating is replaced with mechanical nut rotating, so that the nut can be rapidly rotated, and the working efficiency is high. An arc-shaped pressing plate can be pressed through a limiting assembly, so that a rack on the right side can be prevented from sliding downwards.
