The rear receiving ruler comprises a strip-shaped ruler body B5 and a magnet B6 connected to one end of the ruler body B5, and a through reference hole 51 (shown in figure 5) is formed in the scale surface of the ruler body B5. Like the front receiving ruler, the ruler body B5 can be attracted to the metal plane by the magnet B6 and the ruler body B5 is perpendicular to the metal plane.
When the front receiving ruler and the rear receiving ruler are arranged in the front and back direction on the same straight line and the scale surfaces face the same direction and are adsorbed on the same metal plane, the projection of the reference hole 51 on the ruler body A3 is positioned in the light transmission groove 31 or the length area of the light transmission groove 31 in the view angle parallel to the metal plane; when the laser emitting device and the rear receiving ruler are attached to (the same or different) metal planes, the distance from the reference hole 51 to the metal plane attached to the rear receiving ruler is equal to the distance from the light emitted by the emitter body 1 to the metal plane attached to the laser emitting device.
