Zusammenfassung:	The utility model discloses a knob nut for a forced centering base of a total station, and relates to the technical field of knob nuts for forced centering bases, the knob nut comprises a base assembly, when the knob nut is installed, limiting plates on the two sides of the knob nut are opened firstly, the limiting plates can be unfolded into a linear horizontal shape through hinge of hinge lugs, and the base assembly is installed on the base assembly. The rotary knob nut is inserted into the center hole in the middle of the forced centering base, the limiting plate is clamped into the inner side of the limiting groove at the moment, the protective cover is pressed at the upper end of the forced centering base in a covering mode, and when the protective cover is installed, the clamping block is clamped into the clamping groove, so that the rotary knob nut is prevented from loosening after being installed. After the protective cover is installed, a positioning screw rod can penetrate through the positioning ho
