[0038] Working principle and usage process of this utility model:
[0039] In use:
[0040] In use, firstly, move the insertion rod 642. As the insertion rod 642 moves, it stretches the reset damping rod 642. As the insertion rod 642 moves, one end of it disengages from the second slot 617. After disengagement, rotate the first measuring component 62 and the second measuring component 63. When the first measuring component 62 and the second measuring component 63 are perpendicular to the measuring scale 1, release the insertion rod 642. This allows the insertion rod 642 to reset under the action of the reset damping rod 643, allowing it to be inserted into the first slot 616. When measuring deep holes, first insert one end of the conical bucket 2 into the hole groove. Then, make the bottom surface of the orifice block 611 contact the top surface of the workpiece. After contact, the value coinciding with the bottom surface of the orifice block 611 and the first scale 4 can be read, thus achieving measurement. The hole depth of the workpiece is measured. When the hole diameter needs to be measured during the hole depth measurement, simply pull the pull rod 624, causing the pull rod 624 to move the stop rod 625, so that the stop rod 625 comes into contact with the inner wall of the hole. After contact, the second scale 623 and the third scale 626 cooperate to detect the hole diameter of the workpiece. When it is necessary to detect the height of the annular groove in the hole later, first, make the bottom surface of the orifice block 611 fit with the top surface of the workpiece. At this time, the thin plate 3 of the measuring ruler 1 is inserted into the hole and makes the thin plate 3 contact the bottom of the annular groove. Then, the reading is taken. After the reading, the measuring ruler 1 is moved again so that the thin plate 3 comes into contact with the top surface of the annular groove and the reading is taken again. Then, the height of the annular groove can be measured by the difference between the two readings.
