Development of a measuring instrument

摘要

The invention relates to the inventor of a measurement.At least one pair of polygonal plates (3) with slopes (11);The measured scale of the inclined edge (11) mentioned above (5);The distance (2 9522) between the previous tilt valve (11) and the equal center line (CL) and the previous tilt change (11), the angle between one side is the tilt angle (952);When the above measurement interval (5) is the measured length (a),The expression length (b) is an interval in the form of 2A sin 9522b, which is scaled according to the performance of the above central line system (7);Characterized by inclusion,Therefore, the inclined edge is inserted between the upper and lower portal teeth according to the distance between the upper and lower portal teeth occurring at the inclined edge.The tool quantity is measured by slope measurement and displayed by table.The prosecutor's mouth is correct in a stable state.It is convenient to measure the amount of tools.
