The working surface of the gauge 2 is on the measuring section 21, and in order to cope with different measurement conditions, the measuring section 21 generally needs to be long. To improve the strength of the gauge 2, to maintain the perpendicularity, etc., a reinforcing rib 22 is fixedly attached to the gauge 2. The reinforcing rib plate 22 adopts a triangular rule structural design, the middle is hollowed, and the performance of the gauge 2 is improved on the basis of not increasing too much weight.
