The invention discloses a detection tool for detecting the length from a steering shaft conical surface datum line to an end face and a use method, a positioning cylinder inner cavity of the detection tool comprises a cylindrical length measuring section, an auxiliary positioning section and a detection positioning section, and the diameter of the detection positioning section is the same as the outer diameter of the steering shaft conical surface datum line; the whole sliding block is in an inverted-T shape, the diameter of an upper cylinder of the sliding block is matched with the diameter of the length measuring section, the diameter of a lower cylinder of the sliding block is matched with the diameter of the auxiliary positioning section, and the sliding block can slide up and down in an inner cavity of the positioning barrel. A dividing step is arranged on the positioning cylinder to divide the upper end face of the positioning cylinder into an upper step face and a lower step face, the whole section fro
