The utility model relates to a simple and easy audio -visual displacement recorder contains upper and lower board, pinion rack, jib, ratchet device, contains roller bracket, flexible rule rotary drum, takes scale flexible rule and ink horn, and ratchet device contains rotary drum, carousel, pawl, shellproof steel sheet and gear. When acting as the specific direction relative displacement of hypoplastron emergence, the pawl supports gear inner circle ratchet, drives the rotation of carousel and the removal of flexible rule, then do not drive during opposite direction. Through taking the data on the scale flexible rule, the upper and lower inter -plate accumulation relative displacement at this direction of motion fast can convert out. Get back to initial position if go up the hypoplastron, then positive accumulative total relative displacement in the other direction equals, cotton thread with chronozone look section can be dyeed through the ink horn, and the quilt dyeing hop count volume of positive negative d
