The invention discloses a dirt stripping and locking device for an electric automobile gear shift operating rod. The dirt stripping and locking device structurally comprises a dirt stripping and locking device body, a rocker and a grip. The rocker is moved, thereby entering a gear clamping groove, and meanwhile a cypress annular shaft at the lower end of the rocker also enters the gear clamping groove. When not subjected to external force, a slip rod does not press an outer expansion plate, thus a jacking moving ring elastically pulls a movable foot rod, thus the movable foot rod inwards tightens the outer expansion plate, a left locking groove and a right locking groove of the cypress annular shaft are locked with convex contraction parts, the rocker at the upper end of the cypress annular shaft does not move without pressing, the effect that the rocker does not move to other gears due to inertia of the body is ensured, and traffic accidents are prevented. Oil dirt in a resilience boxis dissolved and removed
