Abstract

A support vertical shaft for a steering operation board of an electric vehicle is vertically connected with the middle part of shaft supported on a left and a right support plates in front of a vehicle frame, and a pair of clutches coaxially sleeved on the shaft are respectively arranged between the vertical shaft and the left support plate and between the vertical shaft and the right support plate. Reset springs acting on the lateral surface of the movable half part and steel balls with an active force opposite to the reset spring are arranged in the clutches, and the steel balls are operated through the operation of clutch operation tubes with corresponding pits. The support vertical shaft is a combined shaft consisting of an upper half vertical shaft sleeved on the lower half vertical shaft, and is fastened by an elastic claw clamping nut mechanism. When the distance between the steering wheel and the driver needs to be adjusted, the clutch operation tube rotates and is separated from the clutches. When the height of the steering wheel is adjusted, the clamping nut is loosened to open the elastic claws. The support vertical shaft is reset after the adjustment. The support vertical shaft has the advantages of convenient adjustment, accurate, stable and reliable result, and better rigidity.
