The mounting plate 1 is vertically mounted on the front side end surface of the mounting bracket 2. One of the step surfaces of each step on the mounting plate 1 is at an angle of 45° to the horizontal plane and tilted upward, so that it is directly in line with the driver's sight when the driver lowers his head, which is convenient for observation. The two side surfaces of the mounting bracket 2 are provided with right-angled serrations 23 that match the bends of the mounting plate. The side serrations 23 of the mounting bracket extend outwardly to form mounting ear plates 24.
