The step driving module 21 can be a step motor or a servo motor, so that the angle parameter obtained after the processing of the processing control module 23 has two calculation modes, if the step driving module 21 is the step motor, the rotation angle is controlled by controlling the number of pulses, and one pulse corresponds to one step angle; if the servo motor is used, the rotation angle is controlled by controlling the pulse time.

The laser emitted by the laser emitting module 7 forms a 90-degree angle with the direction of the rotating shaft 2.

The supporting legs 3 comprise first connecting rods 3-2, second connecting rods 3-1 and adjusting knobs 3-3, the upper portions of the first connecting rods 3-2 are rotatably connected to the lower portion of the first base 1 through U-shaped supports, the second connecting rods 3-1 are connected to the lower portions of the first connecting rods 3-2 through the adjusting knobs 3-3, and the connecting positions of the second connecting rods 3-1 and the first connecting rods 3-2 can be adjusted by rotating the adjusting knobs 3-3, so that the heights of the supporting legs 3 are adjusted.

As shown in fig. 5, the initial angle and the final angle of the blasthole instrument (or default values of the instrument) are set (on the screen), the device starts automatic measurement, and the inclination angle relative to the direction can be obtained after the automatic measurement. Generally, the device can be rotated to align at 90 degrees, and the measurement is arranged again, so that the result in the other direction can be obtained, and the two results are matched to evaluate the inclination quality of the blast hole. That is, by comparing the two results (i.e., the angles in the two directions) with the design angle of the blast hole, the difference is the error, the larger the error is, the lower the inclined quality is, and the smaller the error is, the higher the quality is.
