Background
During the assembly process of the electric power steering gear, an adjusting screw plug and a locking nut (an adjusting screw plug compression gap adjusting mechanism and a jacking rack) need to be screwed down. The adjusting screw plug and the locking nut are in a coaxial relationship, and the adjusting screw plug on the inner ring is generally screwed down first, and then the locking nut on the outer ring is screwed down.
