The utility model provides an automatic measuring instrument that soil sample breathing changes, places the soil sample that awaits measuring including installing the testboard on supporting the chassis on, and the top of the soil sample that awaits measuring is equipped with the laser displacement sensor subassembly, and the laser displacement sensor subassembly includes three group's laser headsof distribution on same high plane, and the three laser head simultaneous ejaculation laser pulse of group are received by the laser displacement sensor subassembly after the soil sample that awaitsmeasuring reflects. The utility model discloses sending to return according to three laser pulse of group and being received time experience, calculate the distance on three group's laser heads and the soil sample surface of awaiting measuring respectively, the recalculation goes out the vertical height on laser head and the soil sample surface of awaiting measuring, combines the vertical height on laser head and testboard
