| description | The utility model relates to the field of testing devices, in particular to a digital display height gauge dial gauge. The transmission wheel (16) is also meshed with the rack of the main stand column (1) or the auxiliary stand column (2), and the device is characterized in that the bottom of the central shaft (13) is rotatably mounted on the upper flat plate (12) through a micro bearing (15); the upper flat plate (12) comprises a groove for accommodating the bearing bowl (14). By the adoption of the technical scheme, compared with the prior art, the center shaft has the advantages that aiming at the defect that the steel balls have certain rolling specificity, so that the center shaft is very difficult to assemble every time, the center shaft is more convenient to install and assemble by the adoption of the bearing. In order to overcome the defects, the lower portion of the center shaft must be machined into a conical face to be matched with the steel ball, machining cost is high, and combination is not easy |
