Galvanizing thickness gauge capable of avoiding abrasion of coating

The invention relates to the technical field of coating detection, and particularly discloses a galvanized thickness gauge capable of avoiding coating abrasion, and the galvanized thickness gauge comprises a detection mechanism, the detection mechanism comprises a detection probe used for detecting the thickness of a galvanized coating on a galvanized steel sheet; the conveying mechanism is connected with the detection mechanism and used for conveying the detection probe to move along the surface of the galvanized steel sheet; the guide mechanism is connected between the conveying mechanism and the detection probe and is used for adjusting the angle of the detection probe, so that the detection probe can directly face the arc-shaped surface when the arc-shaped surface area of the galvanized steel sheet is detected, and the detection result can be more accurate through vertical detection; the problem that in the prior art, when an arc-shaped surface, an arc-shaped convex-concave area or an arc-shaped concave a
