It should be noted that, in order to limit the sliding block, the cross section of the sliding groove 9 is in the shape of "⊥", and the sliding block 10 is adapted to the horizontal part of the sliding groove 9, so that the sliding block can slide along the sliding groove, but will not be separated from the top of the sliding groove.
[0028] Further, a first magnet is embedded in the sliding block 10, so that the standard rod 12 is fixed on the sliding block 10 by magnetic attraction. As one of the embodiments, the first magnet can be embedded from the bottom of the sliding block, and the shape and number of the first magnet can be set as required, and the main purpose is to attract the standard rod to the sliding block. At the same time, the magnetic attraction fixing method is also convenient for replacing calibration rods of different specifications to calibrate different parameters.
[0029] Further, in order to increase the stability of the standard bar on the slider, the top surface of the slider 10 is provided with a V-shaped groove, the V-shaped groove is provided through both ends of the slider, and the standard bar 12 is placed in the V-shaped groove. The length of the standard bar is greater than the length of the slider, and the length of the slider is less than the length of the sliding groove.
[0030] Further, the side wall of the horizontal part of the support block 3 is fixed with a fixed block 4 through a second magnet, and the second magnet is embedded between the fixed block and the support block to be fixed by magnetic attraction. A sleeve 11 is provided through the fixed block 4 and connected with the slider 10, and one end of the cable 5 is fixed in the sleeve 11. It should be noted that the outer diameter of the sleeve is less than or equal to the height of the slider, so that the cable can push the sleeve to further push the slider to slide along the sliding groove, and then the standard bar extends into the detection area of the concave-convex detector. The setting of the sleeve increases the connection strength of the cable and the slider, so that the cable can more easily push the slider to slide.
