The laser point. When the slope cutter is in operation, the traveling device 4 will be displaced in the vertical direction due to the unevenness in the horizontal direction of the guide rail 7. The laser spot received by the laser receiver 3 will also be inconsistent with the initial laser spot. The difference between the points is the same as the displacement generated by the traveling device 4, because these displacements will cause the slope ratio of the working surface of the sloper before the displacement to be different from the slope of the working surface of the slopeer after the displacement Therefore, when these unavoidable displacements occur, the constructor can adjust the lifting and lowering adjustment device 5 according to the initial value of the recorded laser spot position until the initial position is adjusted, thereby saving the previous procedure for measuring the height of the lifting device.
