Background

The compass used by people consists of a top plate, an inner plate and an outer plate, wherein the top plate consists of a thimble, a magnetic needle, a sea bottom line, a cylindrical outer box and a glass cover; the dial on the inner disc is fixed with the upper end of the cylindrical outer box on the top pond; the outer disc is usually square, and crystal lines passing through central holes on the outer sides of four sides of the outer disc form ten celestial centers, namely positioning lines. When measuring a target object with a compass, it is usually necessary to align the magnetic needle with the sea bottom line and then align the target object with the alignment line to read the marks of the scale.

However, when the compass is used for measuring the direction of a building or a wall, because the existing target object such as the building or the wall has magnetic metal such as reinforcing steel bars, if the compass is directly attached to the target object to adjust the alignment of the magnetic needle and the sea bottom line, the magnetic needle is influenced by the magnetic metal in the target object to generate an angle deviation of more than 20 degrees; if the compass is directly placed on the floor with magnetic metal for measurement, larger measurement angle deviation can be generated; in addition, adjust the compass to the horizontality and with the compass after magnetic needle and the seabed line alignment are accomplished simultaneously just can measure the subject matter with the compass, need the compass not be close to the subject matter again in fact and just can avoid great deviation, so it is difficult to obtain accurate data to the subject matter is measured to the handheld compass of operating personnel.
