[0036] Working principle: When in use, shaking the rocker arm 18 drives the worm gear 3 to rotate the worm wheel 25, which in turn drives the third threaded rod 17 to rotate, thereby raising or lowering the four corners of the worktable 4. After the worktable 4 is leveled, the first roller 2 is placed against the vertical wall to be tested. The second motor 11 is started to rotate the second roller 22 to the vertical wall to be tested. When the second roller 22 touches the wall, the pressure plate 23 hits the spring sensor 29. The spring sensor 29 will send feedback to the PLC controller. The PLC controller stops the second motor 11 and starts the first motor 9 and the third motor 34 to move the vertical rod 8 along with the third roller. When the third roller 31 is placed on the top and ground to be tested, the pressure plate 23 will touch the elastic sensor 29. The elastic sensor 29 will provide feedback to the PLC controller. The PLC controller will stop the first motor 9 and the third motor 34, and start the laser instrument to measure the distance. The pusher 13 will push along the trajectory of the first roller 2 against the wall until the test is completed. If there are uneven areas, the second roller 22 and the third roller 31 will touch the elastic sensor 29 again with the pressure plate 23. These test data are transmitted to the display panel through the PLC controller.
