Zusammenfassung:	A flatness detector includes a positioning plate, a positioning assembly arranged on a top surface of the positioning plate, a dial indicator arranged on the positioning assembly, and a sliding block. The positioning assembly includes a first positioning rod and a second positioning rod perpendicularly coupled together and pin-jointed. The dial indicator includes a detecting post maintained as a plumb line by the positioning assembly. The sliding block defines a groove for conforming to the detecting post. A measurement value of the dial indicator is obtained when the groove of the sliding block is conformed to the detecting post.
