Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, a kind of blank of steering link outside link bulb, is made of connecting portion 1 and rotation section 2.
Connecting portion 1 is in the form of a column, and there is chamfering 1 in the outer of one end far from rotation section 2, is prevented when replacing blank
End outer of the connecting portion 1 far from rotation section 2 scratches worker's hand with overlap or burr.Connecting portion 1 is installed with what is be coaxial therewith
Threaded hole 11, while carry chamfering 2 13 in the aperture of the one end of threaded hole 11 far from rotation section 2.
As shown in Figures 1 and 2, the approximate cuboid in rotation section 2, one side is connected with connecting portion 1, and on rotation section 2
It is provided with axis hole 24.Axis hole 24 is connected with threaded hole 11, and the axle center of axis hole 24 is intersected with the axis perpendicular of threaded hole 11.
