When it is necessary to adjust the angle of the ball connecting rod 120, first loosen the threaded connection between the ball nut 130 and the round tube handrail mounting seat 141 to adjust the angle of the ball connecting rod 120, and then tighten the threaded connection between the ball nut 130 and the round tube handrail mounting seat 141 to fix the angle of the ball connecting rod 120.
