Read the value corresponding to the moving ruler 300 on the main ruler 100, and then obtain the GAP value of the car wheel eyebrow. This method enables the user to measure the GAP value of the vehicle wheel eyebrow only by one person. Compared with the traditional measurement method, using the vehicle's Vehicle attitude measurement tool, more convenient and more efficient.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: The technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features thereof can be equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention. scope.
