Novel resistance box automatic adjusting equipment

The utility model relates to the technical field of automatic control. The novel resistance box automatic adjusting equipment comprises a resistance box, the resistance box comprises an outer box body, a display screen, a PLC and a servo motor, the display screen is installed on the front face of the outer box body, the PLC and the servo motor are installed in the outer box body, the PLC is electrically connected with the servo motor and the display screen, the servo motor is used for adjusting the knob position of the resistance box, and the resistance box is located in the outer box body. The resistance box can be installed on an existing resistance box, the resistance values of six frequency bands can be adjusted at the same time through the display screen, manual adjustment is not needed, adjustment is rapid, time and labor are saved, meanwhile, deviation is avoided during manual adjustment, the display screen can display the resistance value of the resistor of each frequency bandat present, and problems
