[0011] Preferably, the length and width of the mounting plate are both smaller than the length and width of the inner cavity of the frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting the sliding groove and the sliding wheel, when the measuring instrument passes through an uphill or downhill road, under the action of the angle, the sliding wheel will slide backward in the inner cavity of the sliding groove and drive the supporting block to move backward. The backward movement of the supporting block will drive the mounting plate and the laser sensor to rotate downward by a certain angle. When going downhill, the sliding wheel will slide forward in the inner cavity of the sliding groove and drive the mounting plate and the laser sensor to rotate upward by a certain angle, thereby automatically adjusting the angle of the laser sensor, so that the laser sensor always remains level, thereby improving the measurement accuracy.
