The guide shaft 15, the scale bar 62, and the pull rod 63 all have a guiding movement function for the limit screw 61. The limit screw sleeve 61 is in threaded fit with the drive screw (the first drive screw 42a or the second drive screw 42 b), so that rotation of the drive screw is converted into translation of the limit screw sleeve 61, rotation angle of the drive screw and axial displacement distance of the limit screw sleeve 61 are in a proportional relationship, and the axial displacement distance of the limit screw sleeve 61 can be reflected on scales (not shown) of the scale rod 62.

The spring 64 applies an inward elastic force to the snap ring 621 to retract the scale bar 62 into the holder 1, and the scale bar 621 cannot read the adjustment amount, but is not easily affected by external moisture to corrode the scale. The anti-slip portion 622 is used to facilitate the extraction of the scale bar 62. When the scale rod 62 is pulled out until the snap ring 621 contacts the stopper 611, the scale displayed is the adjustment amount at this time, the anti-slip portion 622 is released, and the spring 64 causes the scale rod 62 to retract back into the holder 1.
