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 a compass is used to measure a target object, it is usually necessary to align the magnetic needle with the sea bottom line and then align the target object with the positioning line to read the mark of the corresponding dial below the positioning line.

Although people install laser at the front end of the compass positioning line to align the object to be measured, which does bring convenience to operators, the problem that how to adjust the laser head to be consistent with the positioning line, namely, how to adjust the laser head in the outer disc or the fixed die sleeve of the compass can be accurately aligned with the positioning line still exists. The general method for adjusting the direction of the laser head in the fixed die sleeve is to use adjusting bolts on four sides of the fixed die sleeve respectively, namely four adjusting bolts are shared by the four sides of the fixed die sleeve, when the direction of the laser head is adjusted, the adjusting bolt on one side is loosened a little, then the adjusting bolt on the opposite side is tightened a little, the adjustment is repeated a little by a little, the left and right adjustment also needs to be adjusted up and down, the time and the labor are very wasted, and the accurate positioning is difficult to achieve.
